I drive a German car which is known for being fast and it performs pretty much exactly according to specs. But when I go on youtube or in the magazines I am always reading insane figures for my car. Either these people have fucked with the chip or they are "hand timing" which is always faster.
Various ways to get the insane times. The company can suppy a ringer, which Ford likes to do.
Cars maybe tested with half or a quarter tank of gas. Cars can be tested in optimum environments---low humidity, low temp, and on a race track. Cars can be tested with all the electronic aides (traction control, launch control, M button, M dynamic mode, etc) on, giving better times. The E60 M5 had umteen diff configurations for it's SMG III tranny. Diff tires, tire pressures. All of these can be manipulated to get better times. And the drive as well.
There was a vid I posted of the M3 vs. IS-F, featuring Paul Tracy and Tanner Foust, Tracy couldn't launch the M3 correctly, but since Tanner had one, he wasn't telling him how to launch it.
Groink, I sat in and test driven, M3s, RS4s,Z06s, GT-Rs, Porsche 911 Turbos, X5/X6 Ms, M5s, Shelby Mustangs...
Those are fairly easy to get access, all the exotica, unfortunately I have to defer to people that I know
Also, you have these idiots who claim that their stock 135i can give a M3 a run for it's money...with loads of stories...could it be that the poser in the M3 doesn't know how to drive said car?
Same deal with Porsche's Carrera GT, there are many people who have driven it that complain about the slippery clutch, that it's "on and off", then there are those who are "drivers" who have no problem with it.
Bench, the problem is, Porsche is the go to car in the GT2 and GT3 class in Am Le Mans series and the Le Mans 24 hours.
They have won the 24 hours of Nurburing, where many of the cars competing in SCCA would fail.
And the fact they they have won Le Mans numerous times along Ferrari.
I think, Chris Harris of Evo Magazine campaigned one at the 24 hours of Nurburing...
Americans, might laugh, just as Euros might laugh at us for using a Corvette.
***The Viper has won overall at the 24 Hours of Nurburing, but Corvette has not.
