Diesels - best torque per ton?
Any ideas as to what's best or indeed just up there with the best? Will be looking to move current daily runner on soon & diesel is best option for a longish daily commute. Would be nice to have something to enjoy on the slog home ...
Cheers, TX.

335d coupe is about 180bhp/tonne. Can't think of any that beat that apart from mega pricey 8 pot diesels maybe?
More about the torque than power to weight ration though.

What sort of budget? A 170bhp Golf or Leon might be the best option. Around 170lbs-ft/tonne. Torque/tonne doesn't actually "work" but it can be an indicator of oomph - noticed Evo recently used to compare a couple of cars.
Got almost 260 lbs-ft/tonne in my soot chucker - about the same as a Merc CLK Black edition...

Don't forget torque at the flywheel is not indicative of torque at the wheels. A diesel will be a lot longer geared than petrol to make up for the lack of revs, something that always seems to be overlooked - especially by diesel marketeers!

it's the relatively high BHP that makes a diesel a 'good' diesel, the high torque is a product of the engineering required to get this high BHP, you can't have one without the other.

I'm seriously impressed with the Honda Civic 2.2 TDi .... I think it's 350Nm?
In real world driving it is fantastic .... the only diesel I've driven though - but, it would probably beat the scooby in the 30-50 dash? Or equal it probably?

Was going to mention this car myself. Beaten to it.
TBH most Audi / BMW TDI are all pretty good. Just depend on what car size you want.
A3/Golf/1 series size? Then VW/Audi 170bhp TDI or BMW 120d
A4/3series size? Audi 3.0TDI or BMW 330/335D
A8/5 series size? Audi 4.0TDI or 535d

I remember pulling up behind a big diesel Audi a few years back when I had my Spec C (375hp & 375 torque) ... the Audi just teleported up the road leaving me in a cloud of soot

Diesels tend to have pretty flat torque curves when depicted graphically.
With high compression ratios they deliver more torque (and hence derived BHP) from low revs which aids acceleration, especially in gear.

Given that BHP is a derived figure calculated from torque and rpm, you're right in that you can't have one without the other, but more correctly the high BHP is a product of the engineering required to get the high torque.
