370 vs 135

Torque. Torque is often described as the "seat of the pants feel" when accelerating. Small displacement engines are usually light on torque and need a lot of RPM's to obtain peak power at the highest RPM ranges. Larger engines feel the power when you punch it at lower RPM's. A phrase I heard once that makes sense is: Horsepower is how hard you hit the wall and Torque is how much of the wall you take with you....

I never heard this before. But I like it.

Anyway the 370z's torque is very low @ revs blow 5000 rpm,something like 363nm@5000rpm with shows that it needs revs to get going.

And there ya go. So, solve the low-end torque problem, and voila.

I don't think the answer to all this is a measly 30 ft/lbs of peak torque, when you could argue that the 370 has over 30 more HP up top, and seeing as as soon as you get going, the 370 would be living in its optimal power band the whole time its accelerating, giving it the overall nod. He said the 0-60 times were about the same if not identical (I cant remember off hand).

I think this really comes down to seeing the overall power bands on the 2 motors side-by-side. I'd be willing to bet the 370's low-end power is a bit of a handicap, but thats me. I think its holding the car back.
