    BimmerBoost member IMHOWTFFTW recently added some performance parts to his F82 M4 and got the car dyno'd before and after. He purchased the Active Autowerke Active-8 S55 tuning module and also added Zima ceramic downpipes to improve the engine breathing. His baseline on a Dyno Dynamics was 433.3 wheel horsepower. This particular Dyno Dynamics is reading fairly high and seems to be set to read like a Dynojet. What is important to focus on is not the peak figures but the gains. And what nice gains they are. The Active Autowerke Active-8 tune provides a torque gain throughout the entire curve. Peak torque goes up to 520 lb-ft at the wheels. That will provide a nice kick in the pants at 3500 rpm. The peak horsepower gain is 54.2 at the wheels but peak horsepower does not really tell the story here. The torque curve drops off toward redline so you see major gains with the BMW M turbo motors far earlier in the powerband. Thank you to @IMHOWTFFTW for doing independent testing and getting a baseline dyno. Very useful for data for those considering tuning their M4 (and tuner friendly it is).

    The E39 M5 is the camera car in the video and it belongs to BimmerBoost member Omni. You may remember his E39 M5 from an article last month detailing how he went from a supercharged S62 V8 to swapping in an S52 inline-6 six and turbocharging it. Considering the result in the video below, it is difficult to argue with his decision. The performance certainly is there. His S52 turbo setup has shown 708 wheel horsepower but he states in the video he is running roughly 640 wheel horsepower during the race. The E39 M5 does not have the fancy dual clutch transmission the M6 Gran Coupe does and the S52 six-cylinder has less displacement than the 4.4 liter S63TU V8 in the M6 Gran Coupe yet @Omni's E39 M5 makes easy work of the M6 once he hooks up. Definitely impressive to pull on a stock M6 Gran Coupe in an E39 let alone one that is tuned with catless downpipes.

    The Nissan GTR in stock form is a pretty quick car. The 2014 GTR you see on the graph below makes an impressive 452 horsepower at all four wheels and 408 lb-ft of torque at all four wheels. Those numbers are impressive until you put a Switzer Goliath GTR next to it. The standard GTR looks, well, puny. That tends to happen when you put a stock GTR up against a GTR with almost four times the horsepower. The two actually look pretty similar until about 4500 rpm when all hell breaks loose. The Switzer Goliath GTR climbs and climbs until it hits 1744 horsepower at all four wheels and 1102 lb-ft of torque at all four wheels. In other words, absolutely insane numbers. As the Goliath package takes some time to spool the GTR benefits from a 9000 rpm redline. The torque curve actually stays pretty flat from 7000 to 8500 rpm making for some big horsepower figures. Compare these Switzer Goliath figures at 9000 rpm to the Switzer E1K-X-GTR figures at 8500 rpm. They just keep raising the game.

    It looks like a dealer specification sheet for the upcoming 991 generation GT3 RS model was leaked. What we learn is pretty much what everyone already expected as the GT3 RS gets a larger 4.0 liter direct injected flat-6 engine with 500 horsepower and 339 lb-ft of torque. It is interesting they do not seem to be exceeding the 997 generation GT3 RS 4.0 output figures. That vehicle had the exact same horsepower and torque output except without direct injection and also at a lower redline. There is no information on a manual transmission so it seems talk on the subject is just wishful thinking. With less weight than the standard 991 GT3 but more power and torque the GT3 RS is going to be a hell of a track weapon.

    Here we finally are, the new second generation Audi R8 based on the Lamborghini Huracan platform. The R8 is very much a reskinned Huracan and shares the same drivetrain including the naturally aspirated and direct injected 5.2 liter V10 engine as well as the dual clutch transmission sending power to all four wheels. The standard R8 V10 has an output of 540 horsepower and 398 lb-ft of torque. The R8 V10 Plus increases output to 610 horsepower and 413 lb-ft of torque essentially matching the Lamborghini Huracan. As the standard V10 and V10 Plus share the exact same engine one can save some money and simply get some software to get the increased output if they wish. The new R8 is lighter, wider, and lower to the ground. The new aluminum chassis shaves roughly 110 pounds from its predecessor. Less weight along with a lower center of grabity should considerably improve track performance. The styling is evolutionary. The average person might not be able to tell the difference between the first generation and second generation cars. The new R8 certainly looks more aggressive and the more sharply angled headlight design gives it bit of a meaner look. Overall it is exactly what we expected and that is not a bad thing. Expect a V8 and all electric E-Tron version to come later. Ingolstadt, 2015-02-26 Audi presents the new R8: The sporty spearhead just got even sharper - The second generation of the high-performance sports car makes its debut in Geneva - 5.2 FSI engine with up to 449 kW (610 hp), 0 to 100 km/h (62.1 mph) in 3.2 seconds - New multimaterial Audi Space Frame with high proportions of aluminum and CFRP No model with the four rings is closer to motorsport, none is more striking and more dynamic: at the Geneva Motor Show, Audi is presenting the second generation of its high-performance R8 sports car. The V10 mid-engine and a newly developed quattro drive ensure breathtaking driving performance, especially in the top-of-the-range version with 449 kW (610 hp): achieving 0 to 100 km/h (62.1 mph) in just 3.2 seconds, its top speed is 330 km/h (205.1 mph). A high-revving mid-engine with superior performance, a consistently lightweight construction concept and an extremely dynamic chassis with quattro drive system and fully variable torque control – this is what makes the R8 the sporty spearhead of Audi. The high-performance sports car has been newly developed from the ground up – it is more taut, more striking and more fascinating both on the race track and on the road. "Motorsport is in Audi's genes, it has always been a permanent feature of our brand's character," says Prof. Dr. Ulrich Hackenberg, Board Member for Technical Development at Audi. "With the new Audi R8, our engineers are bringing accumulated racing expertise from the race track onto the road. No other model of ours evokes more dynamic emotion. The new R8 V10 plus is therefore the most powerful and fastest series-production Audi of all time." Thanks to the close cooperation between racing engineers, racing drivers and developers, the Audi R8 has seen a clear performance increase – this benefits both the series production car and the R8 LMS developed on the basis of this. The engines: 10 cylinders in two versions The 5.2 FSI is available in two versions: one with 397 kW (540 hp) and another sporting 449 kW (610 hp). The range-topping model accelerates in a mere 3.2 seconds from 0 to 100 km/h (62.1 mph) and keeps going to its maximum speed of 330 km/h (205.1 mph). The sound of the freely aspirated V10 engine, whose maximum torque is available at 6,500 rpm, has become even fuller and sharper. A 7-speed S tronic transmission and a newly developed quattro drive system transmit the power to the road. The distribution of the drive torque adapts to the respective driving conditions – in extreme cases, 100 percent of the torque can be transmitted to the front or rear axle. The new performance mode in the Audi drive select dynamic handling system enables adaptation of the most important ride dynamics parameters to the friction coefficient of the road. Lightweight construction: only 1,454 kg (3,205.5 lb) dry weight The top model R8 V10 plus has a dry weight of 1,454 kilograms (3,205.5 lb). Despite a lot of extra equipment and greater rigidity, the new Audi R8 weighs up to 50 kilograms (110.2 lb) less than its predecessor. The multimaterial Audi Space Frame (ASF) ensures low weight and optimum axle load distribution. The combination of aluminum and carbon fiber reinforced plastics (CFRP) in the Audi Space Frame opens up new dimensions with regard to weight, rigidity and crash behavior. The aerodynamic underbody which integrates a long diffuser boosts downforce. The chassis, too, with its double wishbone suspension demonstrates how close the new Audi R8 is to motorsport. Design: flat, wide, muscular The design reflects the powerful sporty character of the R8. A visual distinguishing feature which also provides enhanced safety comes in the form of the standard LED headlights. For an extended field of vision and more brightness, Audi offers the laser spot for the high beam as an option – complemented by the dynamic turn signals at the front. Dynamic turn signals are standard at the rear. In the new Audi virtual cockpit, the displays are digital. The most important controls are grouped together in button clusters on the steering wheel, also known as satellites. In the interior, the driver has the impression of sitting in a race car. The air conditioning controls emphasize the simplicity of the control panel with its floating effect. MMI navigation plus with MMI touch is standard. Sales of the new Audi R8 start in summer 2015. Prices are 165,000 euros for the R8 V10 and 187,400 euros for the top-of-the-range version R8 V10 plus. New factory for quattro GmbH: production at the "Böllinger Höfe" site The new Audi R8 is produced at a new quattro GmbH production site that was specially built for the sports car – the "Böllinger Höfe" site in Heilbronn. An elaborate manufacturing technique ensures that Audi-typical quality is produced. Specialists: the Audi R8 e-tron and Audi R8 LMS The second generation of the Audi R8 forms the basis for more models. The latest evolutionary version of the electrically-powered high-performance R8 e-tron sports car achieves a performance figure of 340 kW and a torque of 920 Nm (678.6 lb-ft). It sprints from a standstill to 100 km/h (62.1 mph) in 3.9 seconds. Thanks to new battery cells, the range could be more than doubled compared to the first version of this technological wonder – it is now more than 450 kilometers (279.6 mi). The new Audi R8 LMS race car was developed based on the new GT3 regulations due to come into effect worldwide from 2016. This year it will already be put through its paces at the factory. Despite massive performance increases, around 50 percent of its components are the same as the series-production car. The new Audi R8 The R8 is the dynamic spearhead of Audi. In its second generation, the high-performance sports car has been newly developed from the ground up – it is more taut, more striking and more fascinating. The high-revving V10 engine is available in two performance variants. In the top-of-the-range version with 449 kW (610 hp), it develops breathtaking power. "Motorsport is in Audi's DNA, it is part of our brand's character," says Prof. Dr. Ulrich Hackenberg, Board Member for Technical Development at Audi. "With the new R8, our engineers are bringing accumulated racing expertise from the race track onto the road. No other model of ours evokes more dynamic emotion, none is closer to a race car. The new R8 V10 plus is the most powerful and fastest series production Audi of all time." The mid-engine principle used for the Audi R8 is not only a classic concept in motorsport but also an important piece of Audi tradition. The powerful engines were located in front of the rear axle even in the Grand Prix race cars brought to the start line by Auto Union in the 1930s – a revolutionary step at the time. In 2000, Audi won the 24-hour Le Mans endurance race with the LMP R8 prototype for the first time. By 2005, the car which provided the name for today's series-production high-performance sports car had secured five overall victories at the Sarthe – the name chosen for the road version of the super sports car from Audi, R8, indicates the technological relationship between the two winners. As the R8 LMS, the Audi R8 is also highly successful in customer racing. The basis for its success: motorsport was part of the development strategy from the very beginning. In 2009, the R8 LMS customer racing race car began its success story which would lead it to more than 190 victories and 23 championship titles worldwide. Technically speaking, it is closely related to the road version of the sports car with around 50 percent of the same parts. Up to 449 kW (610 hp): the two V10 engines The new generation of the Audi R8 utilizes the latest development of the ten-cylinder engine. With its spontaneous throttle response, quick revving up to 6,500 rpm and inimitable roaring sound, the naturally aspirated 5.2 FSI engine is enough to give you goose bumps. In the new R8, the freely aspirated V10 engine offers even more power and torque than before. Controllable flaps in the exhaust pipe and an optional sport exhaust system make the car sound even more characteristic. The ten-cylinder engine is available in two versions. In the R8 V10, it develops a power of 397 kW (540 hp) from its 5,204 cc displacement and a torque of 540 Nm (398.3 lb-ft) at an engine speed of 6,500 rpm. The sprint from 0 to 100 km/h (62.1 mph) takes just 3.5 seconds, and it can reach a top speed of 323 km/h (200.7 mph). The R8 V10 plus is even more powerful and is the fastest series-production Audi of all time. It develops 449 kW (610 hp) and its maximum torque of 560 Nm (413.0 lb-ft) is available at 6,500 rpm. The performance figures are equally impressive: 0 to 100 km/h (62.1 mph) in 3.2 seconds, 0 to 200 km/h (124.3 mph) in 9.9 seconds, and a top speed of 330 km/h (205.1 mph). A further innovation in the 5.2 FSI engine is the additional indirect injection. It complements the FSI direct gasoline injection, lowers fuel consumption and enhances engine output. Moreover, the R8 features yet another innovative system in the form of COD (cylinder on demand). It shuts off one of the two cylinder banks by deactivating injection and ignition. The R8 V10 consumes an average of 11.8 liters of fuel per 100 kilometers (19.9 US mpg) with CO2 emissions of 275 grams per kilometer (442.6 g/mi), for the R8 V10 plus those values are 12.4 liters per 100 kilometers (19.0 US mpg) and 289 grams per kilometer (465.1 g/mi). The fuel consumption reduction of up to 10 percent compared to the previous model is also due to the new start-stop system. The dry sump lubrication completes the technology package of the 5.2 FSI. The ten-cylinder engine is hand built in the Hungarian engine plant in Gy 014Å'' type="#_x0000_t75">r. As a traditional motorsport technology, it allows for low installation of the engine, which is particularly beneficial for the car's center of gravity. What's more, it also ensures oil supply even under extreme lateral acceleration. Fast as lightning and highly variable: the power transmission In both engine versions, power is transmitted to a rapid-shifting seven-speed S tronic transmission installed behind the engine. The S tronic has three automatic modes and can also be controlled manually. Shift commands are transmitted electronically (shift-by-wire). The launch control system manages full-throttle acceleration from a standing start. Another function of the S tronic comes into play when the driver's foot is removed from the accelerator pedal at speeds above 55 km/h (34.2 mph). In such cases, both clutches open and the car goes into coasting mode. This function saves a considerable amount of fuel, especially in everyday use by the customer. The quattro permanent all-wheel drive system gives the new R8 a decisive plus in terms of stability and traction when compared with two-wheel-drive competitors. On the front axle, an electrohydraulic multi-plate clutch replaces the Visco clutch of the predecessor model. The newly developed quattro drive system enables completely unrestricted and fully variable distribution of the drive torque to the front and rear axles depending on the driving situation and weather. In normal operation, up to 100 percent is transmitted to the rear wheels and, if required, the clutch continuously diverts up to 100 percent of this torque to the front wheels. Thanks to the mechanical differential lock on the rear axle, the driver experiences maximum traction without any slip. Audi drive select: the chassis In the chassis of the new Audi R8, double wishbones made from aluminum guide all four wheels. The R8 V10 plus has a particularly sporty setup – for both engine variants, variable adaptively controlled Audi magnetic ride shock absorbers are available as an option. The newly developed electromechanical power steering system provides close contact to the road surface and makes a further contribution to reducing CO2 emissions. As an option, Audi offers dynamic steering, whereby the steering ratio varies in accordance with the road speed and the settings in the Audi drive select dynamic handling system. As standard, the new Audi R8 V10 has 19-inch wheels with size 245/35 tires at the front and 295/35 at the rear. Upon request, Audi is also offering 20-inch wheels for the first time in the R8. With this option, the tires are size 245/30 at the front and 305/30 at the rear. The steel brake disks have a weight-saving wave design and the calipers can be painted red upon request. In the R8 V10 plus, high-tech disks made from carbon fiber ceramic are responsible for deceleration of the 20-inch wheels (optional for the V10). In the Audi drive select dynamic handling system, the driver has the choice of four modes (comfort, auto, dynamic and individual) to control the way in which important technical components operate. As standard, the system takes into account the engine characteristics, steering, S tronic transmission and quattro drive system as well as optional extras such as Audi magnetic ride, the exhaust flaps and dynamic steering. On top of that, there is also the new performance mode (available as an option for the V10 and standard for the V10 plus). The driver activates it by pressing a separate button on the steering wheel. He or she can select between the programs dry, wet and snow using a rotary wheel. These programs support dynamic handling on dry, wet and snow-covered surfaces. In performance mode, Audi drive select also makes use of the ESC stabilization control function. New Audi Space Frame with high proportions of aluminum and CFRP The R8 V10 plus has a dry weight of 1,454 kilograms (3,205.5 lb). The key factor behind the consistent lightweight design is the body shell with multimaterial Audi Space Frame (ASF): It weighs only 200 kilograms (440.9 lb). The resulting unladen weight of 1,555 kilograms (3,428.2 lb) leads to a superior power-to-weight ratio of 3.46 kg/kW (2.55 kg/hp). The ASF body shell features a completely new multimaterial lightweight construction concept. Components made from carbon fiber reinforced plastics (CFRP) form the B‑pillars, the central tunnel and the rear wall. The front section of the vehicle, the roof arch and the rear section form a framework made from cast aluminum nodes and aluminum profiles which, in some cases, employ new alloys. As always with the ASF, each component is precisely designed for its location and purpose. Accordingly, the engineers have now integrated some components into the body shell due to their function. Leaving aside its components, the body shell is now around 15 percent lighter than its predecessor. At the same time, torsional rigidity is roughly 40 percent better. Particularly with regard to rigidity, the body of the new Audi R8 is a benchmark. The resulting lightweight construction is unparalleled among the competition. The multimaterial Audi Space Frame in the new Audi R8 is extremely light and rigid, whilst also being acoustically comfortable and offering a high level of safety. The outer skin is made entirely of aluminum, but as an optional extra (or as standard for the V10 plus), Audi also offers attachment parts made from clear-coated carbon fiber, for example the front splitter, the diffuser or the side blades. A long, rising diffuser in the underbody produces downforce on the rear axle at higher speeds. Design: flat, wide, muscular A cockpit positioned very far forward, a long, flowing back and a relatively short wheelbase – the exterior design makes the technical concept of the mid-engine, high-performance Audi R8 sports car clear upon first sight. At 4.42 meters long (14.5 ft), 1.24 meters high (4.1 ft) and with a wheelbase measuring 2.65 meters (8.7 ft), its dimensions have only slightly changed in comparison to the previous model. Its width now measures 1.94 meters (6.4 ft) and has thus grown by about four centimeters (1.6 in). The car's proportions convey more of a race car character, with characteristic design ideas from the previous model now more pronounced. The four rings sit proudly on the hood, the Singleframe radiator grille with honeycomb design is wide and flat. Modeled plastic surfaces allow it to merge into the flat headlights – facets of the vehicle which highlight tension, provide an impression of depth and add an air of logic to the design. The grid-type signature of the daytime running lights with vertical elements replicates the structure of the air inlets and emphasizes the width of the car. The entire appearance of the Audi R8 conveys a feeling of lightness and technical precision. LED headlights are standard. Available upon request, Audi can also supply the laser spot which doubles the range of the high beam to 600 meters (1,968.5 ft) as well as the dynamic turn signals at the front. The dynamic turn signals are standard at the rear. The rear lighting signature also combines two vertical elements with a horizontal line. This gives the Audi R8 an even more powerful appearance. As part of the new laser high beams, one laser module per headlight generates a cone of light with twice the range of the all-LED headlamp. Each module comprises four high-power laser diodes. With a diameter of just 300 micrometers, these generate a blue laser beam with a wavelength of 450 nanometers. A phosphor converter transforms it into white light suitable for roadway use with a color temperature of 5,500 Kelvin – ideal conditions for the human eye that enable the driver to recognize contrast more easily and help to prevent fatigue. The laser spot is active from a speed of 60 km/h (37.3 mph) to supplement the LED high beam of the R8 and, thanks to its long range, greatly enhances the driver's field of vision as well as safety. An intelligent camera-based sensor system detects other road users and actively adjusts the light pattern to exclude them. On the sides of the high-performance sports car, characteristically curved contours are drawn over the wheels. The shoulder line, shaped like a powerful muscle, connects the wheels with one another while at the same time dividing the side blade in two to leave an upper and a lower half. This new design solution makes the car appear even longer and more dynamic. At the rear, as well, the lights and the air inlets visually connect to one another. The two tailpipes of the exhaust system have a trapezoidal design and the rear window offers a clear view of the illuminated engine compartment. The R8 is equipped with an electrically extending spoiler, the R8 V10 plus with a fixed wing made from CFRP. Just like in a race car: the interior and the controls Behind the steering wheel of the new Audi R8, the driver feels like a race car driver. All functions are driver-oriented and allow easy operation even when the critical limits are reached – and all without the driver having to take his or her hands off the steering wheel. The newly designed sport seats with integrated headrest provide excellent lateral support. Even more radical seating for a sports car comes in the form of the newly developed R8 bucket seats. These make a clear statement confirming the relationship between lightweight construction and comfort (optional in the V10 and standard in the V10 plus). The start-stop button and the Audi drive select button are located on several satellites on the new multifunction plus steering wheel. The Performance steering wheel in the Audi R8 V10 plus features two more satellites. One button is for performance mode together with a rotary wheel for selecting the dry, wet and snow programs as well as a button for controlling the sports exhaust system. The Audi virtual cockpit is set in a free-standing housing and presents all the information on its 12.3-inch display with elaborately computed, fascinating graphics. The driver can toggle between different display modes and also adjust the digital instrument cluster to his needs in individual mode. In performance mode, the driver is presented with information on the driving programs, acceleration, deceleration and lateral forces as well as power and torque. The Audi virtual cockpit also displays a shift light which informs the driver that the engine speed limit has been reached. The driver operates the Audi virtual cockpit using the multifunction plus steering wheel. The driver's hands remain on the steering wheel and he or she can concentrate on the road. Alternatively, operation can take place via the touch wheel or the buttons in the center console. In the design of the interior too, the taut geometric lines emphasize the aesthetic lightweight construction of the brand. Its characteristic element is the monoposto, a large arc in the area around the driver's seat. The MMI monitor of the previous model is no longer available. Instead, the three central control elements of the air conditioning system have taken its place. The three-dimensional design of the air outlet vents bring to mind the air inlets of a race car. The dashboard appears to float weightlessly. The wide console of the central tunnel accommodates the standard MMI terminal as well as the newly designed flat selector lever of the S tronic transmission. When it comes to upholstery, customers can choose between Alcantara/pearl Nappa leather and fine Nappa leather. Also available are trim elements in clear coated carbon fiber, two leather packages and a new diamond stitching pattern. Customization There are numerous customization possibilities for customers of the new Audi R8 – for both the exterior and the interior. The colors for the body have been newly mixed and can be freely combined with the colors of the side blades – a blade made from glossy carbon is a particular highlight of the range. Ten standard exterior colors are available, for the R8 V10 plus there is an additional matt paint finish available, Camouflage Green. Among the five equipment colors available for the interior, two color ranges can be found, whereby the interior is always characterized by a sporty feel. Additionally, there are numerous options to further customize both the interior and the exterior, for example with headlining in Alcantara with dynamic diamond stitching pattern. The Audi exclusive program makes it possible for you to turn the new R8 into a one-of-a-kind model. Completely connected: infotainment In the new Audi R8, the Audi virtual cockpit replaces the analog instruments and the MMI monitor. The driver can switch the all-digital display between two different view modes. These bring either the virtual dial instruments or the large navigation map into focus. The Audi R8 makes use of the latest technology in terms of infotainment. MMI navigation plus is installed as standard; the MMI touch touch wheel is the central control element. In the background, the second generation of the modular infotainment platform sets about its work – just like the Audi virtual cockpit, it integrates a super-fast T30 chip from Audi's cooperation partner, NVIDIA. MMI navigation plus is complemented by the Audi connect module. The passenger can connect a smartphone or tablet via the system's integrated Wi-Fi hotspot. Tailored online services from Audi connect are displayed on the Audi virtual cockpit. The internet connection uses the fast LTE (Long Term Evolution) network. Optional components such as the fine-tuned sound system from Bang & Olufsen with a system performance of 500 watts or the Audi phone box for convenient cell phone integration round off the infotainment program. New factory for quattro GmbH: production at the "Böllinger Höfe" site The new Audi R8 is produced at the new "Böllinger Höfe" quattro GmbH production site, close to the Neckarsulm plant. The production area covering 30,000 m2 (322,917.3 sq ft) comprises a body shop and assembly facilities. The entire production facility is highly flexible, while technical and ergonomic innovations such as the CFRP body shell construction and driverless transport systems ensure top quality. As was the case for the previous model, production follows an elaborate manufacturing process. In cycle times of about 30 minutes and with up to 400 highly qualified employees, the R8 is created in highly precise craftsmanship. Following completion, each R8 is subjected to a strict quality acceptance process on the internal plant test track and an approximately one-hour test drive on public roads. With the new R8 manufacturing site, quattro GmbH – the high-performance subsidiary of AUDI AG – is further enhancing its small-series expertise, thus creating the opportunity to realize ever more exciting derivatives of the R8. Electrified: Audi R8 e-tron The second generation of the Audi R8 forms the basis for two more models. Audi has made major engineering developments in its high-performance electric sports car, the R8 e-tron. The latest evolution of the vehicle takes up the multimaterial Audi Space Frame from the new series-production model. The supporting structure was enhanced by a CFRP rear-section module comprising the luggage compartment. The walls of the CFRP luggage compartment well are corrugated. This way, in the event of a rear-end collision, more energy can be absorbed despite the reduced material weight. Thanks to targeted modifications to the outer shell and on the wheels, the Audi R8 e‑tron achieves an aerodynamic drag coefficient (cd) value of 0.28. In terms of performance and range, the car enters entirely new dimensions. The large T-shaped battery is structurally integrated into the center tunnel and behind the occupant cell – optimally positioned in the car. It supports the dynamics of the R8 e-tron with its low center of gravity. Audi produces the high-voltage battery itself, for the first time based on a newly developed lithium-ion technology which was specially conceived for a purely electric vehicle drive. In comparison to the first technology platform, the battery capacity has grown from 49 kWh to approximately 92 kWh. This progress was possible without changing the package. The R8 e-tron achieves an electric range of 450 kilometers (279.6 mi) instead of a previous 215 kilometers (133.6 mi) with an energy density that has been increased from 84 Wh/kg to 154 Wh/kg and some other modifications to the car. The electrically powered high-performance sports car has the Combined Charging System (CCS) on board, which allows charging with direct and alternating current. Using this system, it is possible to fully charge the battery in significantly less than two hours. The power is now twice 170 kW and the maximum torque twice 460 Nm (339.3 lb-ft). The R8 e-tron 2.0 accelerates from 0 to 100 km/h (62.1 mph) in 3.9 seconds on its way to an electronically restricted top speed of 210 km/h (130.5 mph) or 250 km/h (155.3 mph). Intelligent energy management and an electromechanical brake system enable high energy recuperation rates. Targeted torque vectoring – needs-based distribution of power transmission between the rear wheels – ensures maximum stability and dynamism. Audi uses the electrical high-performance sports car primarily as a mobile high-tech laboratory. Accordingly, the findings from the R8 e-tron help in creating a vehicle with a sedan character. Upon customer request, the R8 e-tron will be available for order in 2015 as an electrically powered sports car in supreme hand-built quality. New race car: the Audi R8 LMS Alongside the new R8 series-production model, the second-generation R8 LMS race car is also making its debut, with colleagues from motorsport and series production working in close harmony as part of its development. Both the series-production model of the R8 and the R8 LMS have seen clear increases in power and performance compared with the predecessor. Both cars have around 50 percent of the same parts. The body shell of the rear-wheel-drive GT3 sports car is based on a selectively reinforced multimaterial ASF. Engineers have supplemented this feature with a safety cage. Its outer shell consists mainly of carbon fiber reinforced plastics. The vehicle's type approval weight is 1,225 kilograms (2,700.7 lb). The V10 engine is virtually identical to the series-production engine and produces around 430 kW (approximately 585 hp), depending on the applicable regulations and the restrictor required. Sales of the new R8 LMS to customer teams worldwide will start with the 2016 season. This year, the new race car will be put through its paces by the works team at international long-distance and sprint races, as well as being available to customers as part of the Audi driving experience. All technical data is preliminary. Fuel consumption of the models named above: Audi R8: Combined fuel consumption in l/100 km: 12.4 – 11.8** (19.0 – 19.9 US mpg); Combined CO2 emissions in g/km: 289 – 275** (465.1 – 442.6 g/mi) **The fuel consumption and the CO2 emissions of a vehicle vary due to the choice of wheels and tires. They not only depend on the efficient utilization of the fuel by the vehicle, but are also influenced by driving behavior and other non-technical factors.

    Hi Guys, I am new to the forum and desperately need your expert advice. I am finally looking into purchasing my first German car and I can't be more excited! I live in Ontario, Canada and currently drive a Dodge Avenger SXT (Boring!!). But I am torn on the age old question..... BMW or Mercedes?? I am trying to decide between a used 2011 or 2012 C-Class or 3 Series but I just don't know what to get. Please help me answer these questions: - Which one is better for driving in the snow? - Which one tends to break down more/require more maintenance? - Which one costs less to maintain? - Do either of them come with built in XM Satellite Radio or Bluetooth? (Dodge has both and is a huge selling feature for me) - Overall, what do YOU feel is the better model/brand? Thank you guys, looking forward to hearing from you!

    The performance automotive world for whatever reason is not making a big deal out of this claim by Porsche. Somehow flying under the radar is a statement from Porsche which at the Detroit Auto Show announced the 2015 Cayenne Turbo S lapped the Nurburgring in 7:59.74. Under 8 minutes on the 'Ring at one time was the benchmark for a serious performance car. Well, the new Cayenne Turbo S is now officially the fastest SUV around the famed circuit and the first production SUV to lap it in under 8 minutes. This of course beats the laptime of the previous record holder which was 8 minutes and 14 seconds by the Range Rover Sport SVR. The Cayenne Turbo S crushes its time by over 14 seconds. Porsche has not provided a video or any data as a support of its laptime claim though. Does anyone really doubt Porsche's integrity though? Now when we say 'new' for the Cayenne Turbo S we mean changes for the 2015 model year. It is still the same 958 Cayenne platform however Porsche bumped horsepower by 20 from the 4.8 liter twin turbo V8 to 570. Torque is up by 37 lb-ft to 590. There are also minor styling tweaks. This impressive output and performance comes at a price point of $157,300. That is an insane amount of money to spend on an SUV no matter how quickly it laps the Nurburgring. Especially considering one can buy a used Cayenne Turbo, get a tune, and have essentially the same thing except with a bit more power and torque. If you have the money to burn though.... The new Cayenne Turbo S The top athlete among SUVs At the 2015 North American International Auto Show in Detroit, Porsche is also introducing the new Cayenne Turbo S – the top model of the sporty SUV model series. Its re-engineered 4.8-liter V8 biturbo engine now develops 570 hp (419 kW) and 800 Nm (590 ft lb) of torque. A chassis that is tuned for maximum driving dynamics and packs a wide range of control systems also makes the Cayenne Turbo S a genuine top athlete. It can turn a lap of the North Loop of the Nürburgring in 7:59.74 minutes. The Cayenne sets a new record for SUVs here, and it also proves that every Porsche is a genuine sports car – even in this vehicle segment. The more spontaneous response of the biturbo engine is primarily a benefit of the integral turbochargers, which are now housed directly in the exhaust manifolds. This new approach also improves combustion. The high-performance engine offers 20 hp more power and 50 Nm (36.8 ft lb) more torque than the previous engine. The Cayenne Turbo S accelerates from zero to 100 km/h in 4.1 seconds – which is 0.4 seconds faster than the previous model (0 – 60 mph in 3.8 seconds). Its top speed is now 284 km/h (176 mph). The Cayenne Turbo S also underscores its position as a top athlete in its chassis systems. Its standard Porsche Composite Ceramic Brakes (PCCB) include 420 mm front brake discs and, for the first time, ten-piston calipers. The rear brakes have 370 mm discs and four-piston calipers. The active roll stabilization system, Porsche Dynamic Chassis Control (PDCC) proactively reduces side tilt when driving through curves early on. Porsche Torque Vectoring Plus (PTV Plus) increases dynamic handling and stability by making specific brake interventions at the right or left rear wheel – this noticeably improves steering into curves and steering precision. The active hang-on all-wheel drive system Porsche Traction Management (PTM) permanently drives the rear wheels while offering fully variable power distribution to the front wheels. Some advantages of the interplay between all systems: excellent driving dynamics and traction as well as a high level of agility at any speed. Standard features of the Cayenne Turbo S reflect the top level of this model. They include 21-inch wheels in distinctive 911 Turbo design with black painted edges, LED headlights including Porsche Dynamic Light System Plus (PDLS Plus), full-leather interior with Porsche logo embossed on all head restraints as well as interior carbon accents. Interior styling in a black/creme color combination is making its debut in the Cayenne Turbo S. Creating exterior visual accents are the air inlet surround at the front of the vehicle that is painted in high-gloss black, the undersides of the door mirrors in the same color and the roof spoiler and wheel arch moldings in car color. A sport exhaust system is available as an option in combination with a switchable sound symposer, which optimally transmits the V8 sound experience into the interior. The Porsche Cayenne Turbo S will be launched in the United States in late-April 2015. The MSRP for the Cayenne Turbo S is $157,300. MSRP does not include a destination charge of $995.

    Pm me for pix of interested $4400 shipped. This comes with clipped billet 20T compressor wheels (9 blade) and install kit with everything needed (even the VTT shirts are still in box) completely maxed out. Still in box from VTT with packing peanuts and shrink wrapped. Keep your cores and avoid the wait (took mine months to get). Build these on his web site and select no cores. These will still be cheaper. I am going a new direction with custom turbos. If no one wants these I will just send back to Tony wanted to give someone the option tho to have them immediately. If you ordered these today they would be just under $5000 dollars and you would owe your turbos. Keep your turbos and save money and time. Ready to ship.

    650 horsepower already out of the W205 C63 AMG M177 engine with just a tune? Considering that the W205 C63 AMG has 510 horsepower stock along with 516 lb-ft of torque getting 650 crank horsepower from the 4.0 liter twin turbocharged and direct injected V8 with tuning is well within reason. We see similar numbers from the Audi RS6/RS7 and their 4.0 liter twin turbo V8 engine although the Audis send power to all four wheels. The thing is, although the horsepower in theory is possible there is no proof. Is the ECU already cracked? Is anyone flash tuning the cars that have barely even hit the market (and certainly are not available worldwide yet)? To BenzBoost this seems like wishful thinking. Australia's International Autohaus is the one making this claim stating the software is already available and they have backed that claim up with a picture of the W205 engine bay which amounts to no proof at all. Evotech is suspected to be providing the tuning. We know tuners are already starting on the M177/M178 engines and they are even preparing turbo upgrades but a 650 horsepower claim without a dynograph or any proof is nothing more than tuner optimism at this point. It certainly looks like they jumped the gun.

    Owners of front wheel drive third gen EA888 1.8T and 2.0T engines have a new downpipe option courtesy of APR. The APR downpipe is a cast piece featuring T304L stainless steel construction. The downpipe features an integrated catalytic converter for emissions compatibility. That cat is likely sapping some power though due to its location so far upstream. The gains on the 1.8T engine are rather modest as the Stage II APR upgrade including their cat, intake, and software shows 234 horsepower for a gain of only 4 horses at the wheels up top versus the APR Stage I. Peak torque rises by 3 lb-ft. The gains are larger on the 2.0T engine as wheel horsepower goes from 291 for the Stage I to 309 with the APR downpipe, intake, and Stage II software. Torque at the wheels rises to 391 lb-ft from 367 on 93 octane fuel. Certainly nice gains and a nice option for those who wish to run a catted downpipe. Quick facts: Designed and assembled in-house. T304L stainless steel construction. Argon back-purged TIG welding. Investment cast downpipe. 77mm inlet with integrated flange. Low profile, sealed/corrugated flex section. 76mm outlet with integrated bracket. 8mm billet bracket. 76mm brushed and de-burred piping. Non-swedged/slip-fit/flanged piping. Investment cast o2 bung. 300 cell, 100mm x 100mm GESI catalyst. OEM-style slip-on clamps. Reducer for OEM catback compatibility. APR Stage II ECU Upgrade price waived. Limited lifetime warranty.

    Today, at Mercedes Benz of Rockville Centre, which installed my Renntech full tune and Renntech Sport Mufflers, we took a video, from behind the car, of the car from startup to revving. Again, you need to listen with a sound system with a subwoofer to appreciate and hear all of the sound.

    I thought at first it was only blue and black. But now I've seen the same image change colour. I can make it flop it seems by scrolling on this NP article. http://news.nationalpost.com/2015/02/27/is-this-dress-white-and-gold-or-blue-and-black-tumblr-photo-sparks-unlikely-online-debate/ Vice has a good article also. http://www.vice.com/read/heres-whats-happening-with-that-dress-with-the-confusing-colors-882

    That spyphoto that floated the web of an R8 this month? It looks to be a pre-production version of the test car you see below. Audi will indeed be launching their Huracan based second generation R8 later this year and the reveal is expected to take place in the next couple weeks. We have a few early tidbits courtesy of Autocar and everything is pretty much as expected. The R8 gets minor styling changes and rides the Huracan platform. It shares the dual clutch transmission and V10. It really is just a reskinned Huracan with some tuning changes. The standard V10 model is detuned from the Huracan 600 horsepower to 532 horsepower and 398 lb-ft of torque. An aftermarket tune will have no problem bumping the figures back up and the R8 V10 Plus model has the same output as the Huracan. As far as changes from the previous model the new R8 weighs 145 pounds less in V10 Plus trim. It is also 39mm wider and 9mm lower. What about the V8 model? Good question. The car is launching as a V10 first and the venerable V8 will follow unless there is some major change of plans. The supercharged V6 and twin turbo V8 talk from some sites was just a bunch of nonsense. Expect an official release soon. Source
