Default More torque off idle than s2000's max

Nice to see that the Z has more torque off idle than the S2000's peak torque.

Then again, the S2000 is a i-4 2.0 liter engine which was designed for high-revving fun... whereas the 350z is a huge 3.5 liter block (with a max of 276 lb-ft of torque for that matter). Why even make the comparison? .

Because they are similarly priced sports cars, I think.

Default Reasoning

I'm comparing to the S2000 based on the questions about the Z being sluggish, and those saying that other cars including the s2000 have never been considerred sluggish. I have very often heard driving an s2000 below 5000rpm similar to driving a civic, so I'd say that sounds sluggish. Just tired of all the whiners saying the Z isn't going to compare favorably.

Those are actually pretty "duh" answers, I must have been tired or something when I posted my previous response. Thanks for not flaming . And yeah, I heard about that review where they said the 350z is sluggish... I really doubt that also. With a 0-60 time of 5.4 (measured by C&D with a pre-production car that weighed in at around 3350 lbs.. which means that the production cars will be just a tad quicker since they weigh in at an average of 3200 lbs), and 180-some-odd lb-ft of torque off idle, I think the 350z will be able to provide some kick in the butt.

Don't put a lot of credence into that graph. HP & Torque ALWAYS are equal at 5252 rpm. This graph crosses at 5600, give or take.

Yes, I know it comes from Nisson's web site, but they are not always perfect.

Default Why they don't cross at 5252

If you look at the graph, the HP and Torque scales are different, if you look at the torque around 5252, and the HP at 5252, you'll see they are right about the same number, so I'd say it's legit.

Showing my ignorance....

Why do the two curves always cross at 5252rpm?

Basically it stems from the fact that one ft-lb of torque at 5252 rpm is equal to 33,000 ft-lbs per minute of work, and that's equal to one horsepower. The equation is:

horsepower = (torque * RPM)/5252

And so from that equation, when the RPM is equal to 5252, the torque will equal the horsepower. And that's the case for every single dyno sheet .

... ah.. that's the only piece of Physics that I'll ever care about .

Looks like I need to brush up on my Physics!

Thanks for the great briefing question that I get to use on my student aviators now!
