Name me few Engines with a broader powerband ?
Discussion
Are we talking about spread of torque over the operational rpm of the engine, or torque over the "absolute" rev range of the engine??
This has torque across it's entire operation range:
peak torque=80rpm, peak power=80 rpm !!! ;-)
A modern DI gasoline engine will make 100nm/litre across practically it's entire operating range
(say 1250 rpm to 6750 rpm)

Is a 3 litre petrol better for broader power band than the 3 litre diesel from BMW?
Never driven a large diesel engines and those I have driven have a tiny window of power.
from the standard dyno's, looks like the 330d has about a 500rpm plateau where it has peak power, before hitting the limiter...Never driven a large diesel engines and those I have driven have a tiny window of power.
That's not a very broad powerband, perhaps he meant torque band...
Most decent sized petrol or diesel engined cars will have a broad power range. Sure the gearing and weight of the car the engine is in will have some relevance in the actual driving experience.
Just to say, I don't think my 530 diesel BMW has a broad power range at all, it comes on like a switch at 2500 revs and builds till 4500 then runs off, not broad at all IMO. My 6.3 V8 petrol engined car pulls much nicer and very strong from 3000 rpm right to 6000 limit, but would pull even lower in the rev range with a less radical cam.
My old twin turbo V6 2.5 MItsubishi had bags of torque off boost, then nuts till 7K. The 4 litre straight six Jag was pretty good too.

I never knew that, I assumed it would have been the land of the rising sun, learn something everyday (where all the best engines come from ;-)
Went out in the GT-R today and it really is a remarkable engine, oodles of torque, doesn't matter what gear, what rpm it just drags the cars ass up to silly speeds in seconds, I bloody love it!

This one generates 1001hp and 175,250lbs of torque at a mere 30rpm
