Think you're a bit confused about torque and BHP.

No I'm not.

I am pointing out that unless that great torque can be used to develop high
end horsepower.....who cares. 10 times the low end torque is essentially
meaningless if high end horsepower is unachievable, and as good as the new
diesels are, they still haven't bridged that gap in a way that compares to
petrol response.

Since a normally aspirated gasoline engine doesn't develop either
torque or horsepower until relatively high rpms

Please. Any motor of any type which works and turns develops both torque
and bhp. At any rpm. If it developed neither, it wouldn't turn. It only
needs to develop just slightly more than its losses through friction, etc,
of course.

Dave, the total area under the 3.0L gas engine's HP curve is greater
than that under the diesel's 3.0L HP curve. As Ray says, it's HP that
gives acceleration, because you have to measure the *WORK* done
to get to a specific speed. Torque != work. That's all that Ray was
trying to say (and Ramone, also, I believe.)
