Got my uprev

Hi Ages - Nissan markets the 370Z as 332 HP, why didn't the test get up to that?

Thanks,

Nissan's rating is at the crank which doesn't take into account drive train losses. When people dyno/tune their cars it's measuring the hp/tq at the rear wheels.

car manufacturers need to rate cars hp at the wheels,not at the crank.

I say they should just provide both sets of numbers. It's not like they don't have chassis dynos at their disposal.
