    Yesterday we saw a tuned Volkswagen MKVII GTI pull away from a stock CLA45 AMG on the highway. Well, in the interest of fairness it's time to see how a tuned 45 AMG M133 does against some tuned MKVII Golf's. The MKVII VW Golf's in the video are not the GTI model but the R. In theory, a tuned Golf R should be quicker than the GTI but it is heavier due to its all wheel drive. The A45 AMG of course has all wheel drive and is a bit heavier than either. The vehicles racing all feature dual clutch transmissions. Here is the mod list for each vehicle: Camera car Golf R - custom exhaust and intake, Stage 2 Revo tune Second Golf R - custom downpipe and intake, HG Motorsports intercooler, and Stage 2 Revo tune Mercedes A45 AMG - Renntech Tuning Box, cat delete, Rebellion TCU remap The first run video is a low speed roll with the A45 AMG versus the camera Golf R. The A45 AMG just pulls away steadily as the cars dodge traffic (Russians, naturally). The second run video features all three cars lined up. The Golf R's are pretty close to one another and essentially even. The A45 AMG though pulls away decisively and continues to steadily pull. What is interesting is that this not with any Renntech flash tuning but just the Renntech piggyback box. The AMG M133 four-cylinder takes this one easily.

    Great tuning here from Eurocharged. The baseline figure you see is from the Porsche 997.2 Turbo. As you likely know the 997.2 switched to a direct injected 3.8 liter twin turbo flat-6. The power and torque figures are strong with 461 horsepower and 469 lb-ft of torque at the wheels. That is on 93 octane pump fuel. Considering the 997.2 Turbo got a 20 horsepower bump on paper to 493 horsepower it certainly looks to be considerably underrated. Let's take a look a the tuned figures also on pump gas. This is another one of those times where peak horsepower does not tell the whole story. Peak horsepower goes from 461 to 505 at the wheels for a gain of 44 horsepower at the wheels. However, look at the torque curve. At 3500 rpm there is an additional 120 lb-ft of torque at the wheels. That is a strong increase down low which is night and day over stock. It also results in an additional 80 horsepower at the wheels at that same rpm. You will notice there are torque gains throughout the entire curve. The difference in area under the curve from 2750 to 5000 rpm is huge. Not bad for just a flash tune only on pump gas, eh?

    Hot on the heels of the Car and Driver 6-speed manual ATS-V test comes an 8-speed 8L90 automatic ATS-V test from MotorTrend. If we were to guess a deal was struck that Car and Driver would get to publish the numbers first but that MotorTrend would get the automatic press car to test. Magazine politics at work? Just a hunch. Anyway, the MotorTrend figures are more impressive showing 0-60 in 4.0 flat for the auto versus 4.2 for the manual. The 1/4 mile time for the automatic ATS-V is registered as 12.3 @ 114.6 miles per hour. Slightly less than the 115 trap speed recorded for the manual although 3/10's quicker. It also was not tested on a level track so we should in theory see better numbers eventually although these numbers are from a VBOX. It is not as quick or as fast as a DCT BMW M3/M4. Unless owners of the ATS-V come up with a miracle to top the 1/4 mile times we have been seeing from the F80 M3 and F82 M4. Once again, Caddy's boss was wrong about having the Germans whipped in power, torque, and acceleration. Ok, how about the handling? The skidpad figure is .98g or about a wash with the BMW M3/M4. MotorTrend did not delve into the steering feel or handling too much instead saving these details for an upcoming comparison to the BMW M3. That may be why we are missing their figure 8 test numbers. They did state it does feel like a driver's car. The brakes did not fade on the track. The ATS-V stopped from 60 miles per hour in 103 feet. They got 99 feet for the M3. Expect more details in their upcoming comparison as major ones are missing such as the curb weight. We wanted to see how much weight the automatic transmission adds. Regardless, this car is not an M3/M4 killer once again and is certainly not besting the C63 AMG in raw power or acceleration. Is it a better driver's car? Well, we await their direct comparison. 2016 Cadillac ATS-V Coupe BASE PRICE $63,660 PRICE AS TESTED $78,995 VEHICLE LAYOUT Front-engine, RWD, 4-pass, 2-door coupe ENGINE 3.6L/464-hp/445-lb-ft twin-turbo DOHC 24-valve V-6 TRANSMISSION 8-speed automatic WHEELBASE 109.3 in L x W x H 184.7 x 72.5 x 54.5 in 0-60 MPH 4.0 sec QUARTER MILE 12.3 sec @ 114.6 mph BRAKING, 60-0 MPH 103 ft LATERAL ACCELERATION 0.98 g (avg) EPA CITY/HWY/COMB FUEL ECON 16/24/18 mpg ENERGY CONS., CITY/HWY 211/140 kW-hrs/100 miles CO2 EMISSIONS, COMB 1.03 lb/mile

    Very cool race here between a Lamborghini Huracan that is stock except for an exhaust system and a modified C7 Corvette Z06. The Z06 is the same car we saw go 9.891 @ 141.64 in the 1/4 mile on E85. The Z06 also is a 7-speed manual car meaning driver skill plays a significant part. The first run is from a roll. The Huracan is given the hit and takes a lead. The dual clutch transmission helps hold off the Z06 on the first couple gear shifts. Once they get into higher speeds though the power difference shows and the Z06 just pulls away. It's clearly the more powerful car here. What is nice to see is that they also go from a stop. The advantage is squarely in the Huracan's court as it has all wheel drive. That is likely why the Z06 gets the hit off the line. It takes off but you soon see its tires go up in smoke. The Huracan quickly passes by it opening a lead thanks to its traction advantage and dual clutch transmission. Unfortunately we only get one camera angle but it is easy to tell the Huracan is ahead of the Z06 and holding it off. It takes an eternity for the Z06 to catch up which it eventually does. In a street matchup from a stop the Huracan has the advantage unless a Z06 is wearing drag rubber in anticipation of such an encounter. Very nice runs and high quality video to boot. The Huracan does an admirable job considering it is naturally aspirated and has less power and torque:
