I'm talking specifically about the noise from the engine at idle, not the exhaust.

I think that you have a valid point. My northstar V8s are very quite at idle after they are warmed up. I think that calling the pushrod designs barbaric is a bit over the top though (that was not your post though). I will point out that the DI 3.6 has a noise problem that is a result of its design.

Lexus is charging $60k for the IS-F and that only has 416hp.
And BMW is charging over $60k for the M3 and that only has 410hp and 2 less doors!!. Better yet, Porsche is charging $60k for the Boxster and that doesn't even have 300hp.  Also Lotus is...
I can go on and on and on you know. 
By the way, I'll take NA over FI anytime.

62vettefp posted a mention about autolinedetroit.com and a discussion about picking and driving the Car of the Year award candidates in another discussion here on Edmunds.
I'm posting the link for the video of the PBS show in Detroit from Sunday.

Toyota's 5.7L has less power and torque and a lower redline while having no advantage in efficiency. Ranger rover's supercharged 4.2L only makes 390hp.
Really? Let's see...
Caddy Escalade:
6.2L V8 with 403hp/417lb-ft = 65hp/67lb-ft per liter
Toyota Sequoia:
5.7L V8 with 381hp/401lb-ft = 67hp/70lb-ft per litter
The only reason why the Escalade 6.2L V8 is more powerful is due to the larger displacement.
Ranger rover's supercharged 4.2L only makes 390hp.
That's 93hp per liter mind you, SC though.

I havent been in an escalade at idle but in other cars I can say idle is quiet and smooth. In any test where db ratings are provided you can compare noise levels between DOHC and OHV motors and the difference is minimal, if it exists at all.

LOL, it was only a matter of time before the old hp/L argument surfaced. Its a meaningless stat, especially when comparing OHV engines to DOHC engines. An OHV engine needs more displacement to make comparable power because its 2 valves/cylinder. There is no way around that at all. Thats like saying a turbo engine makes more hp/L than a NA engine and is automatically superior. NA engines need more displacement because they cant get as much air into the cylinder as a FI engine. The bottom line is this: the Escalade doesnt suffer in any way by having an OHV engine. Its just as fast as the competition and gets comparable mileage. In the end that's all that matters. The driver of the Escalade probably cant tell you what type of engine is under the hood. Specific output is only important to people who are fans of Honda engines and want to brag about how much power can be squeezed out of a small motor. BTW, .5L isnt that small when tallking about V8 engines. OHV engines have come a long way. The 3800 V6 makes about 200hp while 3.5L V6s from Toyota and Honda make 268. thats a much larger difference than exists between the Toyota V8 and the GM 6.2L V8.
