TGP's have very low drag coefficients...

[90TGP]

I was VERY surprised that the 1990 TGP has such a low drag coefficient compared to other sports cars. It has the same as a C5 Vette!

TGP-0.299
C5 Vette-0.30
Viper GTS-0.35
DSM Vert-0.32
Skyline GTR-0.35
McLaren GTR-0.50
Jetta-0.36
Porsche 944 Turbo-0.33
80s 300ZX-0.33
80s Corvette-0.36
IROC Camaro-0.37
Turbo Thunderbird-0.36

where did you find these #'s from their very interesting.

I just typed drag coefficients into yahoo. Most of them came from a website that cars from the 80s and Supraforums.com. I think you can get a lot of them from car magazine websites [like motortrend].

Yeah, aerodynamics was a big thing when the W-bodies came out.
One of the first advertisements I had ever seen for the then new 1988 Cutlass Supreme coupe was that it had a drag coefficient of 0.297.

Not to sound stupid but what exactly do those numbers mean?

[GnatGoSplat]

Lower numbers are better, means less drag, better aerodynamics.

On the other hand, if you like G-bodies or pretty much anything American from the early 80's, I guess you'd prefer higher numbers. :)

That's what I thought it was. Thanks for the clarification.
