I've been checking out the Saturn sports coupes lately (hey, the Geo won't last forever you know) and have been comparing the SC1 with the SC2. I like the SC1 because it looks just like the SC2, tends to be a lot cheaper than its dual cam version, better expected fuel economy, and it has its peak torque at lower rpm.
However, I noticed one large difference about the 2 models in terms of aerodynamics: the SC2 has a Cd of 0.31 while the SC1 has a Cd of 0.33!
Other than the wing mirrors being the same colour as the body with the SC2 the cars look virtually the same to me. Why would the SC1 have worse drag than the SC2?
The side sills look different. Other differences could include the foglights creating different airflow, wheel size and/or vehicle height. Merely guessing...
I thought about the fog lamps and the different styled rims too. I think that rear spoiler creates more drag than if it was without one (forces the air upwards before separating from the car). Indeed the site says the spoiler is for looks and doesn't mention any aerodynamic improvement. Could you explain more about the side sills?
For starters, you could option any sohc s-series to look like its dohc sibling. My car is an SL but it has the appearance and interior of an SL2. It only lacks the rear taillight valance on the trunk.
The cars pictured show slightly different wheels and thats it. Leading me to believe the CD would be identical. The CD would however differ on the less option laden base model SC1.
The following is my personal speculation why the number is higher for the SC1.
Usually the SC1 is without a spoiler and has hubcaps on 14" wheels. The spoiler and wheel combo of the SC2 could contribute to a better CD. Also
SC2's are more likely to have fog lights thus blocking more of the bumper cover.
Those numbers could be for a previous year car.
Its is somewhat confounding to me that the SC2's CD is only .005 lower than my SL sedan's. It does after all appear to have a much nicer taper to the rear of the car.

Now that I looked at other models, the Silver SC1 in the pic looked to have a slight notch running at the very bottom of the door at the bottom of the body. It turns out they're similar except for the spoiler.
I was curious as to the SC's weight vs. the SL's:
SC1 = 2379 lb.
SC2 = 2437 lb.
SL1 = 2351 lb.
SL2 = 2403 lb.
Pretty similar and the 4-door costs less, and could be more practical. If you're looking to haul more cargo than passengers, then the hatch is the winner. Plan on taking you and 2-3 others comfortably? Then the SL is the choice.
For me, the Integra's ability to haul LOTS of stuff trumps a Civic 4-door for utility, but is heavier, and is a true 4-seater (or 2 -- sitting in the back stinks).
