• Audi previews the 2016 TT-RS / TTS+ and high output 2.0 liter four-cylinder with the aggressively styled 420 horsepower Quattro Sport Concept

      Do you happen to think the styling for the new third generation Audi TT that debuted yesterday is still a bit on the 'cute' side? Well, fortunately Audi showed up to Geneva with an ace up their sleeve showing what the TT looks like on steroids. Meet the Audi TT Quattro Sport Concept. Aggressive styling? Check. That gloss black mesh grille alone makes the TT looks like it is ready to eat anything alive it comes across on the road.

      It also has the performance to back up the looks with 420 horsepower from a 2.0 liter four-cylinder. Let me type that again. 420 horsepower from a 2.0 liter four-cylinder. Audi clearly is not messing around with their desire to take the world's most powerful production four-cylinder crown as they alluded to earlier this year.

      Audi is set to produce a high output version of the EA888 2.0 liter motor for S3+ models and this same motor could go into a TTS+ model. A jump from roughly 300 horsepower to 420 horsepower for the motor is gigantic. If anyone can do it though it's the man in charge of the engine development Friedrich Eichler who created what is currently the world's most powerful production four-cylinder in the AMG M133.

      If Audi does produce a model like this it likely will not have 420 horsepower out of the gate as they are just showing off that they can here. Something in the upper 300's makes more sense which is still insane. 420 horsepower would mean the TT-RS would have to go to 450+ horsepower. Then again, Audi already stated they intend to take the 2.5 TFSI inline-5 to the next level in output so maybe Audi is about to go off on everyone.

      We will have to wait and see what happens but this concept bodes well for future TT performance models and Audi performance in general.








































      The Audi TT quattro sport concept show car
      Four-cylinder 2.0 TFSI engine with 420 hp
      Impressive 210 hp per liter of displacement

      Prof. Dr. Ulrich Hackenberg: "An extreme driving machine for the motorsports enthusiasts among our customers"

      Audi to present a truly special show car at the Geneva Motor Show. The Audi TT quattro sport concept embodies the dynamic potential of the new Audi TT in its purest form. Its two-liter TFSI supplies 309 kW (420 hp), which the car puts on the road via the quattro all-wheel drive.

      "With our Audi TT quattro sport concept show car, we wanted to demonstrate what the new TT's technology can do if you take it a step further," explains Prof. Dr. Ulrich Hackenberg, Board Member for Technical Development. "This car is designed for racing an extreme driving machine for the motorsports enthusiasts among our customers."

      Powertrain

      The engine in the Audi TT quattro sport concept makes a powerful statement. The 2.0 TFSI has a power output of 309 kW (420 hp) at 6,700 rpm a new benchmark in the two-liter category. Its specific output is 155 kW (210 hp) per liter of displacement that's more than even 2001's victorious Le Mans R18 racing car, which was the first time Audi combined turbocharging with FSI direct gasoline injection. The four-cylinder engine has 450 Nm of torque (331.90 lb-ft) available in the engine speed range from 2,400 to 6,300 rpm. with over 300 Nm (221.27 lb-ft) already available at only 1,900 revs.

      At a curb weight of 1,344 kilograms ([2,963.01 lb] without driver), the Audi TT quattro sport concept is an athlete in peak condition. Each hp supplied by the two-liter TFSI, which itself weighs under 150 kilograms (330.69 lb), needs to shift less than 3.2 kilograms (7.05 lb). The four-cylinder engine catapults the show car from 0 to 100 km/h (62.14 mph) in just 3.7 seconds.

      Head of Powertrain Development Dr. Stefan Knirsch: "This high-performance power unit is an impressive demonstration of the power reserves available in our EA888 engine range. This power unit has received numerous awards all over the world and it already lives up to its claim in many Audi sporty models. In the TT quattro sport concept, it demonstrates its full power potential. The thirty-five years of experience we've gained in the field of turbocharging are manifested in this engine's unique combination of maximum performance, dynamism, and fuel efficiency."

      The high-performance engine is once again based on the successful EA888 technologies such as the Audi valvelift system (AVS) variable valve timing, dual camshaft adjustment, and dual injection system (FSI plus MPI). A wide range of modifications are featured, including special aluminum pistons with integrated cooling channels and an ultra-high-strength forged steel crankshaft.

      The cylinder head is a systematic further development tailored to the higher loads and increased gas throughput. To accommodate the higher output, the EA888's familiar, highly compact thin-wall cylinder crankcase is here made of a high-strength cast alloy. The also newly developed exhaust-gas turbocharger features optimized mixed-flow technology and produces up to 1.8 bar of charge pressure.

      When driving, the four-cylinder unit's pronouncedly sporty character is breathtaking. The turbocharged direct-injection engine responds immediately to the throttle and revs eagerly right up to the fuel cut-off at 7,200 rpm.

      The 2.0 TFSI transfers its torque to a compact, three-shaft S tronic. The dual-clutch transmission shifts gears in split-seconds, adding its share to the show car's impressive acceleration.

      The permanent quattro all-wheel drive delivers the power to the road. For optimum weight distribution, the hydraulically actuated, electronically controlled multi-disk clutch is located on the rear axle. The quattro drive actively controls distribution of the drive torque between the axles in milliseconds, thus adding to the car's dynamic handling.

      Chassis

      With its cutting-edge chassis McPherson wheel suspension with aluminum components at the front and a four-link layout at the rear the Audi TT quattro sport concept offers sharp, precise race car handling. The stiff setup brings the body closer to the road when compared with the series-production TT. 54 percent of the weight rests on the front axle, 46 percent on the rear. ESC electronic stabilization control, which can be partially or fully deactivated, complements the suspension's sporty character.

      When cornering, wheel-selective torque control kicks in. If necessary, drive torque is transferred from the wheels on the inside of the bend to those on the outside. Thanks to the distribution of torque, the car turns very slightly into the corner, helping the driver. This allows for precise and neutral cornering and the TT greatly increases its dynamism and stability.

      Body

      A significant part in the Audi TT quattro sport concept's lightweight design is played by the body, which is based on the MQB modular transverse matrix. Its hybrid concept represents the latest evolution of the Audi Space Frame (ASF) and further lowers the car's center of gravity compared with the second-generation series-production TT.

      The front end is made of steel. The passenger compartment floor comprises high-strength, hot-shaped steel components which, thanks to their extremely high strength, feature very low wall thicknesses and thus weigh accordingly little. The compartment's structure, the entire exterior skin, and the doors and lids are made of the classic Audi semi-finished aluminum products cast node, extruded profile, and sheet metal.

      Exterior design

      The flat Matrix LED headlights and the broad Singleframe grill dominate the study's front end. The grill's striking frame displays the quattro logo and holds the dark diamond-pattern grill.

      Through their pronounced edges, the substantial air intakes which also feature diamond-pattern grills appear almost like inserted airboxes. They thus illustrate a key element in the new Audi TT's design language: elements like the greenhouse and wheel arches create the impression of being individual bodies, thus producing the typical tension. The show car rests on 20-inch wheels with a central locking mechanism and semi-slick tires.

      A splitter made of carbon-fiber reinforced polymer (CFRP) stretches toward the front to round off the front end at the bottom and increase the downforce on the front axle.

      The silhouette of the Audi TT quattro sport concept which features a paint finish entirely in Crystal White is athletic and dynamic from every angle. Typical for a TT, the wheel arches form the classic semicircles. They extend 30 millimeters (1.18 in) further than on the series-production car on every side, giving the car's stance on the road a decidedly confident air. They are connected by powerfully accentuated sill trims. Their lower segments are made of CFRP. Together with the splitter and the rear diffuser, which stretch all the way to the wheel arches, they form an aerodynamically effective contour.

      On the rear, the wide CFRP diffuser that extends beyond the vehicle silhouette underlines the show car's racing character. Delineated by vertical edges, the diffuser surrounds two large, fully circular tailpipes that are located further outward than on the series-production car; large air outlets are positioned on the sides beneath the taillights. A large, fixed wing increases the downforce on the rear of the Audi TT quattro sport concept.

      Interior styling

      The show car interior has been reduced to the essentials, doing away with numerous components that are dispensable on the race circuit.

      The door panels have been stripped of armrests and speakers the interior is characterized by Alcantara. A dominant diagonal strip of Alcantara acts as a door pull handle, the door openers feature a filigree design. Low-set racing buckets serve as seats, featuring black four-point seat belts with white accentuating stripes. The luggage compartment offers space for two racing helmets.

      The same as in the series-production TT, the controls are designed purely for the driver. The Audi TT quattro sport concept's pilot has his hands on a compact steering wheel with a pronounced rim that flattens out at the bottom. The steering wheel's spokes house the red start/stop button alongside the keys and rotary buttons for operating the Audi virtual cockpit. Depending on what the driver sets, the fully digital instrument cluster's 12.3-inch display shows different views.

        aside from the 420 sticker on the side, this car looks amazing.

        Also, $#@!ing 420hp from a 2.0l 4cylinder, from the factory? That's just insane. Especially when you consider the fact that the first generation of the EA888 2.0 4cylinder TSI had 200hp. Would love to know all the hardware/fueling changes made to accomplish this. I'm sure it's more than just "toss a bigger turbo on it"

        Take a look at the press release they go into some of the changes.

        Regardless, VW/Audi is about to have the world's most powerful production four-cylinder. I think the production version won't be over 400 though but they certainly can if the want to.

        I seen, just isn't answering some of my curiosities. It's great that they are strengthening the engine though. Wish they would have mentioned the rods along with the pistons/crankshaft.

        Also curious as to whether they changed the compression ratio at all and what boost pressure the turbocharger would be operating at. They say capable of "up to" 1.8bar, which is what, 26psi? Think they went twin-scroll? I may have missed it if they mentioned it somewhere.

        Even a sub 375bhp engine in these cars would be fun. I would love to see the long term reliability of a factory stock 420hp 2.0L 4cylinder engine though.

        I don't think the specifications are set yet.

        It is heavier than the regular version though, even with the stripped interior.

        Not by enough for it to matter. 2960 pounds with a full cage is badass.

        420 hp in that little thing would be a thing of beauty... my mate here has a 2012 (?) TT-RS and that just flies (hp =?)............. nice for cornering, which is what this game should be all about as well

        I hate the front GRILLLLLLLLLLL though... it goes on forever AND is as FUGLY as a cab full of NY women

        The only things that looks out of place to me are the machined aluminum uprights for the wing. Looks great otherwise, and 420 hp from a four cylinder with a warranty is amazing.

        Let's see how much power they offer with this new four-cylinder. 420 sure would make a huge statement.
