M550d

[geek]

I know it's a diesel and it isn't coming to the UK but who fancies one?

[geek]

That's a resounding no then!

I just dont see the point in a 5.0l deisel.
Just get a proper M5

[Mr V10]

It isn't a 5.0l, it's a three litre triple turbo.

....I am a torque addict. I didn't 'believe' until I had DMS breathe on my 535d. I am now in the best of both worlds; the RS3 gives a wave of diesel esque torque up until around 4k and then brut horsepower driven shove takes over upto the limiter.

Having said the above, I haven't driven the F10 M5; turbo v8 must be a sensation and a half.

Oh dear. Thats worse. Triple turbo is a stupid idea. Why not have a larger second turbo to increae torque/bhp. Thats one more thing that will go wrong. And with BMWs ceramic bladed turbos they usually do. Unless its hanged. BTW on mobile so thats reason for sp/punct errors.

[Mr V10]

Triple turbo is a clever idea, Audi will probably try one five/six years later. They've just caught up with the '35D engines.

Triple turbo is not clever on a 6 cyl deisel. I am sorry but if BMW went with a large second turbo with progressive pressure increase up to the lazy 4k or whatever they rev too. Yyou could probably get more power with just as smooth acceleration.

Sorry for going on but this is just amother ooohhhh look we put 3 turbos on a deisel. Were soo clever.

What would have been clever is keeping woth 2 turbos amd getting the smooth delivery and power increase.

I drove a new X50d around brands hatch a few months ago and was rather impresses with the effortlessness of the engine and gearbox combo

I have had Both a 535d and x5 with same engine both remapped and they are stonking cars and it only took Audi about 8 years to catch up with a Twin turbo diesel

I also had a new M5 on loan last Christmas and put about 1k miles on one. The slippery roads won't have helped but I didn't really enjoy it all and it almost killed me twice!

+1 on the 535 and X5 ownership. I also had a brief stint in a 335d touring. Such a flexible engine.

How did it feel tuned to x50d levels, same as a DMS car?

If it is the setup i beleive it to be, The third turbo isn't in series.
It's connected by a gearing mech direct to the crank.
So there is a small turbo for response, a larger turbo for power and the third one that adds every last bit direct to the crank (not compressing air) under full load conditions.
It makes a surprising difference - I plays with a prototype one a few years back that you could electronically enable and disable and when climbing hills if was very noticeable when activated.

Pick up was amazing but this will have also been masked by the seem less 8 speed auto.

You don't get the same sense of speed on the circuit as a road but it was swift but no I didn't consider one

Bet in a 5 series it is a weapon - the F10s just leave me cold

Agree 535d is great. Power smooth and fast. Personally I would have gone laeger second turbo route and too be honest I have never driven the 550d.

Maybe the car modder in me saya larger for more powr.

[geek]

The F10 is a bland thing to look at and to sit in. Will be interesting to see how the new M3 turns out; the F30 leaves me just as cold as the F10.

Eh? They've been there (twin turbo diesel), done that, about eight years back actually! I had a 335D with a twin turbo diesel for two years, it's Audi who it took nearly a decade to catch up. BMW have now moved the game on, don't knock the '50d until you've tried it, you thought the engine was a 5.0 10 mins ago which shows how little you actually know about it. If anything, the only pointless diesel ever made, if any, is the 6.0 V12 TDI in the Q7.
