[QUOTE="si|verfish, post: 1380824, member: 2758"] Not that I'm a track expert or anything; but the Americans will tell you that horsepower sells cars, torque wins races. Basically its the torque that does the work of moving a vehicle. More torque means more force to move the car. BHP is the rate at which the torque does its work. Basically you want usable thrust at useful RPMs. Doesn't necessarily mean high RPMs. If you are driving a race car, you want lots of the poke up high because that is where you will be most times. If you drive a car for everyday, you want useable power all over. Usually when you push an engine to make peak horsepower at high revs you lose peak torque. And vice versa. Bear in mind I'm just speaking from my own observations, so I might be wrong. Take the new Audi S4 for instance. They used a Lambo V10 from the Gallardo. In the Gallardo it makes more bhp but in the S4 it makes more torque down low. And that makes sense because you want a peaky engine for sportiness and you want a muscular engine for autobahn cruising. But you cannot make an absolute case on which is best for a "normal" car. These are not race cars built for a specific purpose. A revvy car needs short and close ratios for its gearbox to take advantage of its relatively short powerband. A torquey motor can take advantage of really tall gearing. Read the Z06 Vette road tests. You can pull with one gear most times even when cornering while a revvy car would probably need to shift a hell of a lot more to stay in its narrower powerband. BTW, it isn't fair to compare the engine out of a car like a 328 (built for normal use) to an engine out of a car like a CTR or a DC2. Those are pretty high end engines for sportier driving. If you really want to compare, take the one from the M3 and see how the Japs like it. [/QUOTE]
