Re: Why do Europeans hate Vipers so much? The most accurate way to see how high performance a car is you have to look at torque.Horsepower is just a calculation of torque and rpm . (Torque/rpm)5252=Horsepower so the reason why the Honda S2000 puts out 120HP/L is because it is tune to put out torque at a high rpm at the cost of long life. The reason for going with a 8.3 liter engine is so that it can put out a descent amount of power with out high rpm enginge damage. So the redline is low even though the engine can rev higher they keep it low so it can last longer. So really you should look at torque per rpm and compare all sportscars then you will see that the playing feild is pretty level Corvette Z06 70ft lbs of torque per liter 360 Modena 76ft lbs of torque per liter Ford GT 92ft lbs of torque per liter Lamborghini mercielago 77ft lbs of torque per liter saleen s7 75ft lbs of torque per liter so all of the cars are pretty close but the ford gt has forced induction and all of the american cars but the s7 are under 100,000 Grand and due to low rpm will have a longer engine life.
