25 pages ! 25 bloody pages ! We're talking about diesel here, the fuel of public transport, HGVs, repmobiles and caravan-tuggers. Eeeeh, I remember when this place were all about Porsches, Maseratis and Lotuseseses, what's Pistonheads comin' to ?  ETA - 26 pages now ! D'oh !

I remember when it was all fields, and there were still diesel threads.

"Since torque has no effect on top speed."
Are you being serious? Your car makes peak power at 7500 RPM (just an example) if you increase torque at 7500RPM what do you think happens to the top speed of the car? Am I being serious? Yes. Completely. The top speed in the situation you describe would increase, because top speed is directly related to power. Not torque. Say 2 cars make the same amount of torque, but one of them makes more power. All other things being equal, it will be the faster car, in terms of top speed. I think you're both right - top speed will occur at a certain rpm; for a given gear ratio, the speed will be exactly the same at that rpm. That top speed (assuming no engine limiter is acting) will be when the driving force of the engine is countered by resistive forces of friction, air resistance etc. If top speed of a car is achieved at 7500rpm, and then was made to make more torque are 7500, it would allow the engine to reach e.g. 7600 thereby allowing it to reach a higher top speed. Because the engine is making more torque at 7500rpm, it also making more power, exactly as you said.

It's directly related to torque, and engine speed. Which is power.

He's saying the one with more torque will rev higher, therefore have a higher top end, assuming the same gearbox. This is really f  king simple. Or at least, it should be. I'm oot.

A diesel thread has turned into an argument about torque. Who'd have thought it?

To be honest it's a bloody stupid argument. I'm off to start an argument about how red is a better colour than blue... It's about as meaningless as this one

This is really f king simple. Or at least, it should be. I'm oot. It should be simple so just remember! BHP = TORQUE and REVS. Its the RESULT. Torque and revs MAKE power. Ok? The more torque you can produce at max RPM, RESULTS in more power. BHP is just the result of more torque at a certain RPM.

I'm sorry your opinion is wrong, the 335d is better and is far more PH...

Lol.
Seriously though, really cant understand the hate sometimes, why not just enjoy both for what they are?
BOTH engines have pros and cons.

For the record, the 1.9d 65bhp non turbo unit in my Kangoo van is balls
