Although the LSA CTS-V2 was more powerful on paper, its supercharger and carbon ceramic brakes put a toll to its straight-line performance ("only" 4 mph faster than LS2 CTS-V1 in both the quarter-mile trap speed and maximum speed departments) as they added extra weight and bulkier aerodynamics to the car. But at least it did GREAT on the track!
