The toughest study known to automobiles...

Notice Chevy, GMC, Pontiac and even Oldsmobile!!!...all average or better. Most are well above.

Contrast with Nissan. Could only muster average in one category - powertrain. All others fell below average.

Even better - compare Buick and Cadillac to Infiniti. These are their respective marques' PREMIUM brands. GM absolutely CLEANS UP while Infiniti embarrasses.

 

Good stuff. I always wonder why the Buick drivetrains do better than the rest of GM as they are the same through out GM on many different platforms..

 

Im not reading all this but a 5mph difference in only the 1/4 mile is a nice pull away. Have you noticed 06 C6 Z's are in the low $50K range too.
