Performance Diesels

Its also worth noting that most new performance diesels have a twin-turbo (or at least thats what I think it is), which eradicates any lag. Another step towards a 'drivers' car for you fussy people 
I suppose you just need a 'phat' exhaust now for the hoes to be impressed by!
You'll cave in soon enough!

Are you thinking of twin scroll turbo?
That's not the same as twin turbos.
I'm actually comparing it (my tdci focus) to a N/A 1.2 or 1.4 petrol; it's only a few insurance groups higher, isn't uncomfortable on motorway runs and pulls like a train (again, relatively speaking- compared to a 330/335d it's nothing).
Why are you doing that? They don't even do a 1.2 Focus.
What, accelerates slowly but can tow huge loads?
Depends entirely on which setup they have. Some do, some dont.
You realise how torque works and translates into power on the road, right?
'I love the torque' is probably the most misguided of all diesely statements.
Did you know that Alonso's F1 car has less torque than a Seat Leon diesel? Them Seat Leon Diesels is well quick innit, got loads of torque right?

I'm well aware of that
It's all in comparison to other cars I might have bought, a Fiesta or Corsa for example. But if it makes you any happier, lets say I'm comparing it to a 1.6 MK1 Focus. Abysmal MPG for what it is, needs to be ragged for similar performance and isn't even that much cheaper than a derv in this price range.Having test drove a few petrol Focuses (Focii?) I can safely say my derv matches the 1.8 petrol. I wouldn't settle for a horribly slow car having learnt in a Fiesta ST of all things, and despite it being a low-end diesel it works just fine.

Yep. In terms of "Reducing lag" Twin Turbos are completely gay in comparison to a single variable vain turbo which can pretty much dial out all sensation of lag. Especially if the twins are in a parallel configuration (Are there any diesels that run a sequential turbo setup? Strikes me as odd to reserve a turbo for "High revs" when they have a lol worthy rev limit).

You might want to go and recheck the tax banding as they are not in the same band at all, the ED 335d is in band H (174g/km) and the 335i is in band J or K dependent on manual (196g/km) or auto (202g/km).
Performance is near identical when comparing auto to auto with the 335i 0-62 5.8 and the 335d 0-62 6.0. But then magazine tests have shown they are very close across the entire range, and hence why I said ALMOST identical not identical or exactly the same...
I went from the average MPG my cousin gets in his car as thats real world figures I had to hand. But as an example today we drove 180ish miles combination of motorway and town driving, 2 adults + 2 kids and random junk in the boot, for the trip the average consumption was a not overly bad 44.3 mpg used about 1/4 a tank.
I think you might want to go and drive one of the BMW, Merc or Jaguar twin turbo diesels. BMW and Merc use sequential and Jaguar use parallel with a variable geometry larger turbo with a secondary non-variable coming online at 2800rpm. The setup they use does pretty much eliminate lag, I can't detect any driving mine and when you can run it to the 5200 rpm limiter, which BTW in every gear over 2nd puts you way into bye bye license speeds, and pulls from 700rpm I'd say that's quite effective.

Thats one of the bugbears on this forum about torque but isn't totally true that it has no meaning. Lots of torque low and low revs will still give you good BHP at the flywheel. Same as a lot less torque but high RPM. How do you think the 535d is quicker than the 535i these days with less book BHP. It has a much more torque spread over its rev range which equates to a much higher average BHP.
Fair enough.
I've always thought lag was over rated. "Power is only a downshift away".
and for some reason you can't shift down in a diesel?
My mistake, there is a £40 difference or so in tax. On a £20-40k car. lol
See above - the 335i is rather more than its book figures. At least the yank ones are, nobody over here seems to own a 335i so they are rarely discussed
Besides, if we are discussing book figures, direct from my 2008 E92 brochure:
335i 0-60 5.5 seconds (5.7 automatic)
330i 0-60 6.0 seconds (6.2 automatic)
335d 0-60 (6.1 automatic)
But we all know how 0-60 isn't the greatest indicator of performance. Either way, the 335i is quicker, the 335d is more economical. Both are fantastic - but if you want ultimate performance you buy a 335i, if you want the best blend of performance and economy and you dont mind the low speed minicab soundtrack, you buy a 335d. Both are excellent cars.

I was told by a friend (who happens to be a Mercedes engineer) that it does eliminate lag.
I'm not going to pretend to know lots about cars mechanically (I dont
), but he would have no reason to lie to me and I trust he knows what he is talking about. He said its only on the very new engines and that diesels are improving very rapidly for the performance market.
I actually drove the petrol equivalent of my car (3.5L Petrol), and I could have had one if I really wanted, but other than the fact it sounds a little bit better (I think the Diesel sounds very nice in a different way to be fair), it would have ended up costing more and I didn't find it any more fun to drive. Granted, I wasn't thrashing the nuts off it round a track.
