HP/Liter will tell you how efficient an engine is, but it's not comparison to determine how fast a car is. People fail to factor in weight into the equation.

Power to weight is a much more important ratio to consider.

HP per liter of an S2000 = 120/liter
HP per liter of a C5Z06 = 71.05/liter

Power to weight of a stock S2000 = 11.81HP per lb.
Power to weight of a stock C5Z06 = 7.69HP per lb.
