That's why I was asking. Since torque is rotational force, you need something pushing harder. So you're look at NM (torque) vs NM/s (hp). I was looking at torque and hp curves for the VQ and LS3 engines, as I will be in the market for a new car and am def looking at the 370 and Camaro. The Camaro might be a little too big and heavy for me, but I'll see that when I go to test drive it. And yes, I understand the Z gets 330 hp @ 7000 rpm.
The Z does have much more grip even vs the Mustang with a Track Pack. Personally, I will never buy a Mustang unless it is over 30 years old. Anyways, the big V8s have a ton of grunt, and the derivative of the torque and hp curves is much much less than the high revving engines. But the Mustang's engine also produces more CO2 per mile than the Z's. Forgive my non-American way of disliking Mustangs oh mighty internet gods. But I am a male, and do love non juice V8s in any form, including pushrod.
The Camaro has enough grip for you, but the Mustang doesn't? Even though comparisons between the Camaro and the Mustang have said that the handling of the two cars is a toss-up, a "driver's race"? If the Camaro is grippy enough, the Mustang is as well.
Don't know about the actual curves, but the 4.6 in the Mustang redlines at 6,500 RPM with a power peak at 4,500 RPM. If the VQ doesn't even peak until 7,000 RPM, then it's a dead cert that the 4.6 is making a
lot more torque at low RPM.
As far as the "more CO2/mile" than the Z's engine, there's just not enough difference to be relevant to any discussion.
350Z: 17/24
Mustang GT: 15/23
I averaged 21.5 mpg with my '06 Mustang GT when I had it and was commuting in the city every day.
There's not going to be any meaningful difference in how much fuel is consumed by these cars. And since CO2 is purely a function of the amount of fuel burned, the difference in CO2 emitted is irrelevant.
