Good specs and price but it's turbo-charged. Turbo does have it's drawbacks.
Most modern supercars I know are N/A
Even though BMW made a 335 turbo the M3 is still N/A. BMW opted for larger displacement engine and did not use turbo on a smaller engine. The 335 though drives well on the street it's not the case on the race track where it is plagued with heatsoak.
Even thogh Porsche make all turbo cars yet the GT3 RS is N/A
Mercedes has gone away from making Super charged engines across the board.
There are other issues related to drivability.
Just some things to note.
You are wrong, according to the reviews, like the Porsche GT2 (which is Porsche's flagship car, not he GT3 RS) the twin turbos have
no lag and i'm sure there is a built in turbo timer, so that is taken care of, no draw backs here.
Maybe the skyline is different. Still makes you wonder why most top model sports cars are N/A. Why Mercedes would switch to N/A from Supercharged.
Like? The CCXR, that's supercharged? The Saleen S7 TT, that's turbocharged? The Bugatti Veyron, that's turbocharged? The Lotus Exige S, that's supercharged? Porsche GT2 and the Nissan GT-R that are turbocharged? Corvette ZR-1 that's supercharged? The Ariel Atom that is supercharged?
Ferrari, Porsche GT3 RS, Lamborghini are really the only ones in the high end market still N/A. With technology today it is better to make a turbo car with no lag than anything else. Why? You have no lag, it's just like a N/A motor, with more low end tq and more high end hp.
