What makes the Japanese V6 engines so powerful given their smaller displacement compared to the larger GM Northstar V8?
lies
hence SAE J2723

A Lotus Elise... Actually, it's a heck of alot faster. (yes it's significantly lighter but you weren't THAT specific)![]()
But you're missing the point. Load that RX-8 up with a car full of people and all their stuff and then see how fast it is. Just like my semi-truck example, the RX8 can do a small amount of work VERY quickly. Good for it. The average Buick driver doesn't want to wind up to 7000 rpm, even if they do want to accelerate quickly. Neither do I in the Focus where fuel economy is more important to me than high horsepower.
The reason horsepower gets a bad name is becuase, as was said before, it's virtually meaniningless in AVERAGE, EVERYDAY driving situations. Unless you race a guy down an onramp everyday, it's a relatively poor measure of performance. Not to mention how much gearing has a huge impact, the size of the tires, the weight of the vehicle, all that...

The GM 3800 V6 was probably one of the best engines ever made. They can take a hellacious pounding,have tons of power,run smooth as silk,and simply will not wear out or break. You can cruise those things at redline and they don`t even struggle! I think GM quit making them because they were lasting virtually forever and no one was buying new cars,but instead driving and driving those with that engine.

I owned a 3800 in my camaro, tons of torque - so much so I broke the 5-speed in it twice and had to trade the car! gm makes great engines but they still need to make better quality cars for them to be put into.

The 60's musclecar ratings are even worse lies though! The "exaggerations" don't apply to the 2007-model engines in the original post anyway.

After all, how many set-ups can you find where the engine will run at 1900 rpm (in 6th gear) at 70 mph?

GM's new 3.6L VVT V6 will take the place of its GM 3.8 predecessor in terms of performance, value, and reliability in the mid-sized segment with the next few years.

Ford took an interesting approach to the Mustang in 1986 that #@$%! off a lot of loyalists, but actually helped performance if people stopped looking at hp / tq numbers. They lowered the hp from 210 to 200 on the 1986 GT, but revamped timing so the torque curve ramped up earlier in the rev range, so the 1986 actually outran the 1985 in 0-60 and 1/4 mile times...in essense doing more and working less. It's a good point when comparing Japanese and American iron (or aluminum, as the case may be).

I haven't bothered to read through this entire thread, but wanted to comment on the IS350.
Yes, it runs mid 13s in the quarter. No bull****, I saw it with my own two eyes many times... That's corvette/fbody territory in a 3400+lb v6 sedan!
