Cargraphic 911 GT3 RSC 3.8 vs Geiger Corvette Grand Sport Kompressor vs MTM R8 GT3-2 R-tronic

1st place - Cargraphic 911 GT3 RSC 3.8 - The tuned GT3's engine produced 474 hp, 39 hp more than the stock one. The gearratios are shortened for the track-use, that's why its topspeed is "only" 293 km/h (per GPS). The acceleration is the best out of the trio: 0-200 km/h in just 12,7 seconds. Braking performance is brutal, even if the car's equipped with the standard brakes (no PCCB). The Sachsenring tracktime of 1:34,69 min is just 0,06 seconds faster than the stock 911 GT3 RS' time. Handling and cornering is on RS-level.

2nd place - Geiger Corvette Grand Sport Kompressor - Corvette Grand Sport with a supercharger, ZR1-wheels and rear-spoiler. Sounds good, isn't? Actually it's not that good... The engine now produces 550 hp (38 more than a Z06) and 653 Nm of torque, and that's too much for the 335 mm-wide rear tyres. The car hit 100 km/h in 4,5 seconds (0,5 seconds slower than a Z06 and a whole second slower than the mighty ZR1). The topspeed is impressive however: with its shortened 5th gear the testcar reached 325 km/h. Braking performance? From 200 km/h 157,8 metres - that's unacceptable from a supercar like this.

3rd place - MTM R8 GT3-2 R-tronic - The most interesting car in the test. The engine: V8 with supercharger, which produces 560 hp and 580 Nm. Straightline performance: the Launch Control is hard on the clutch (only 3 launches are allowed, than you have to wait 'til it cools down), 0-100 km/h is 4,3 s (same as the standard R8 with R-tronic). Topspeed is 295 km/h - with the original bodykit 317 km/h is possible. Handling: the testcar was a pre-production one, as they say: "it isn't brilliant yet, but quite a fun to drive". On the Sachsenring the car was 0.9 seconds faster than the R8 V10 R-tronic. And it will be faster...
