Here are the key results from the Supertest (the turboS was equipped with the aero kit, both cars on Bridgestone, both cars with PCCB, same weight):
NBR-NS: 7.44 vs. 7.47 (both numbers are frustrating...)
HHR: 1.10,9 vs. 1.12,1 (frustrating as well)
Wet handling: 1.37,1 vs. 1.37,4 (bad as well)
Max-speed on Doettinger Höhe: 295kph vs. 288kph
0-200: 10.6s vs. 10.8s
0-100: 3.1s vs. 3.2s
200-0: 134.5m vs. 138.6m
fuel consumption: 15.8l/100km with both cars
I really would be interested in the corresponding figures on Cup/Corsa tires. I guess they won't be much different, otherwise Porsche would have sent a corresponding test car.
How did Porsche manage to build a car with such a bad suspension? The test results are really crappy. Even in the latest version of the turbo.
