No, no, no, NO! For several reasons.
1. Sports cars, traditinally do NOT have a back seat.
2. Sports cars are NOt just 2 door versions of high-perf. 4dr sedans...
3. Sports cars are either RWD or AWD with the majority of the power going to the REAR wheels
4. Any self respecting "sports car" manufacturer would follow Rule #3.
The Cobalt is not a "Sports Car" Supercharged or not.
While it does come in a sporty bodystyle and has a great
5-speed avail;able it is FWD and that it the deciding factor.
The Chevrolet Corvette (ALL), Porsche 550 Spyder, Shelby Cobra Roadster 427, Mazda RX7,
Toyota MR2, Mercedes SL300, (1955) Dodge Viper, Mazda Miata, Datsun 240Z, BMW Z3/4,
Pontiac Fiero (as long as it's a 5-speed)...
those are SPORTS CARS.
Then there are the GT/2+2 sporty coupes and other "sports-car-like" cars that are close
but still do net get a cigar in my book. Case in point: BMW M3, Pontiac GTO, Toyota Celica,
Beretta GTU/Z, Thunderbird SuperCoupe (2.3 turbo), Corvair Monza Turbo, Merkur XR4Ti
Mini Cooper S, Mercedes SL600 etc.
And there's also stuff that I DO consider to be sports cars but some might say that they
are NOT. i.e. Porsche 911 (back seats) or Mazda RX-8 (back seats)...
Is my Maxima a "sports car" since it has datsun 240Z guts... inline-six with MPEFi, IRS,
4-wheel disk brakes, RWD & a 5-speed? NO. It's a sports sedan, NOT a sports car....
and yet I think it's a LOT closer to a "sports car" mechanically than a Cobalt.
Right now GM sells only THREE sports cars in the USA. Chevrolet, Saturn & Pontiac each
get one & the later of the two are related. The 04-06 GTO was sport-coupe & the fourth
gen. F-bodys were Muscle Cars, not sports cars.
