So you're saying that just about every performance car out there has more torque?

ACtually to be fair, I've been reading a lot in the web about the 35 vs the 37, and its application in the cars themselves, and it appears that the G37 is making ~around~ 260 to 270 HP at the wheels, and 230 or so tq at the wheels, while the 35s and 350z's only made 220 or 230 or so hp at the wheels, and less tq. So the G37 is somehow making a lot more whp than the actual increase would suggest,a dn more tq to the wheels while retaining the same amount, essentially, at the crank.

Here's some education:

Look at an F1 car's HP and torque. All power, less torque, ridiculously high rpm's. Works beautifully on a race track driven at 10/10ths all the time with gearing designed specifically for track conditions.

Back in the real world, a usefully low and broad torque curve will result in a much more pleasant car to drive in all around conditions. Someone mentioned the new turbo diesels as a good example.

The G is amazing when really pushed to high rpm's...the performance squeezed out of 3.7L of naturally aspirated engine is pretty good! The gearing is explicitly designed (with higher-gear ratios getting closer together like in a sports car) to maximize the performance of this sort of engine.

But, for the 99% of the time we are not driving as if we were on a race track, 269 hp and 328 ft.-lbs. of torque would be a much better choice. However, the car would likely not "feel" as fast as the current one, even though performance in the normal speed range (between 0 and 100 mph, with gearing designed for lower revs) would likely be identical or even better. Fuel economy would be better due to the lower gearing. Noise would be less due to the lower revs.

The car would be slower in a drag race. Period.

Everyone is so concerned about the PEAK tq figure for some reason, when it really doesn't matter how much peak torque an engine makes unless you're WOT.

What??? It's peak HP that doesn't mean squat unless you're at WOT. Torque is what you feel in the seat of your pants when you stab the throttle.

And I was about to agree that the example car (269hp and 328 tq) would probably be slower in a drag, but, once again, that's a WOT example. But when I think about it, maybe it wouldn't be. A 335i has 30 less hp than our cars, but 30 more tq, and it spanks our car. So who knows? But it's all moot, because our cars are what they are - high hp (for a V6) at high revs.

were just a top end car... end

Again, looking only at the peak figures. The reason the BMW is faster is because it has a larger area under the curve. The peak is definitely lower.

That's why the G starts to pull as you get to higher speeds.

Just thought of this.

If low end torque is THAT much more important to you, go buy a genesis coupe.

Since you put it in that sense....il take the extra hp.

That's interesting; I would have thought that the 335i would have a flatter torque curve.

By "spanked," we're only talking about less than half-a-second difference in the quarter mile time based on the figures I've read from various auto reviewer sites. Yes, that's a lot in terms of drag racing, but nevertheless both cars can do under 14 seconds. And that comparison doesn't seem like it would make a huge "seat-of-the pants" difference.

I love for the G to have more torque, but not at the expense of horse power. I dont't know why people want the driving feel of a 1979 Cadilac Devile; it was all ye hall (lots of torque) until 4000 rpm then the engine just roll over and snore like a senior citizen.
Think more torque with less rpm horse power is better? The 335d diesel have 400 bf of torque at < 2000 rpm but slower then the 335i because the lacks of top end.

The G has the same image where I live -- especially the coupe. lol
