Hey guys and gals! With the release of the new Ferrari 812 Superfast I had a question about engine Tq and HP figures.

Why is it that so many of these exotic engines have such disparate figures when compared to more domestic engines?

For example:

Ferrari 812 Superfast: 789hp, 530 lb-ft TQ
Lamborghini Aventador: 700hp, 507 lb-ft

But then you have the LT4: 650hp, 650 lb-ft
and the Hellcat engine: 707hp, 650 lb-ft

Why the big difference?


Also, the new ferrari has those numbers and goes 0-60 in 2.9 seconds at 33XXlbs. The C7 z06 corvette does the same 0-60 with more than 100 less horsepower and some more pounds.

How much horsepower/torque would it take to get a C6 Z06 to break the 3-second barrier?

Generally exotics have smaller displacement engines that rev much higher even though they may have more cylinders. The more rpms the more horsepower but less torque. The zo6 and hellcat have boosted engines which create more torque. The heavier the vehicle the more torque you want to get it moving.

Yep, an engine with 500 ft/lbs of torque has twice as much hp at 10,000 rpm as 5,000 rpm.

Here's another wrinkle.
My wife's SUV is supposed to do 2.8 @ ~5400lbs.. I'll have to test it with some timing equipment but power to the ground and how the car and driver manage that is key.

Rob seriously get it out on the strip for few passes we need time slips
