We can thank the late 70's and 80's emissions laws for that, to make up for less power they just made everything handle like a roller coaster and have the aerodynamics of a golf ball.

how in the hell does a tercel have a lower Cd than a 4th gen? that right ther makes me question the accuracy of that list for sure...

and since we're on the subject of aerodynamics and random stats, aerocoupe monte carlos w/ the slanted back glass brought the c/d from 0.375 for the standard g-bodies down to 0.365 which was worth another 5mph on NASCAR tracks

This thread was good for a few luls...

Coefficient of drag is only one part of the aerodynamic picture. Frontal area is another very big part of that picture. Put Cd together with A and you have CdA, a much more accurate picture of how the shape of the car interacts with the air relative to top speed per a given power level.

Read the Wikipedia link posted earlier, there is a lot of good info in there.

if the fbody was to have the dimples like a golf ball all over it...the car would easily do 180...I have a 93z...lowered on adjustable coil overs 3 in the rear 2 in the front with light weight 18in American thrust 18x10 and 18x9 with nittos zr rated...bored and stroked to a 402 stroker with full roll cage and a 4in header back straight pipe x pipe, with a stage 3 comp clutch and a tune and I struggle to hit 180...also running 3:43 with a weld for posi trac
