Time to Transform again.. Goodbye Zed

That is what really impresses me about the 640d in that it weighs 1800kgs yet it still manages to return 40 mpg and I think that is really good going for the performance it offers, and the 600 mile range helps cut down the fill ups a little too.Sae said:bluestreak56 said:
That's pretty impressive considering your lugging what - 1800kgs about, however not keen on the filling up station bills at the end
If I had to be harsh though a Diesel engine hardly ever gets the pulse racing sadly and I wish they offered the X4 M40i in the UK because that looks like a really stunning bit of kit 8)

Most of it was driving with cruise on so it sits coasting at 70 downhill. I dont like putting cars into neutral when travelling at speed (my dads always said you lose full control of the car when you do so) but I dont think you really can the 8sp auto as you say. With the cruise off, I just lift off the accelerator and it goes into charging mode.
Stop button? Do you mean start / stop? If so yes it locks the steering lock when stopped.

Yes 1820kg according to BMW, but presumably closer to 1825kg when you add on all the electric seats, 20" Alloys, reversing camera, folding mirrors, prof nav pack, harmon karmon sound system, adaptive headlights and climate comfort windscreen..
Agree with you its no Zed performance wise but it is a great cruiser and has plenty for overtaking.
Agree RE the power of the X4 M40i but looks wise they havnt done enough and as you say the fact the UK gets no petrol variants at all is a shame.

Prices are falling, Ive seen some around the £30k mark. You're right in the next 2 years expect some to be £20k or so.

Hi Sae, its more economical if you leave a car in gear on downhill sections as they use no fuel that way, if put in neutral the engine is still burning fuel in order to tick-over
regards
If that's true, then its worth knowing
I believe it is.
My A3 is more economical in 'drive' than it is in 'eco'. The only difference is it doesn't knock itself into neutral when the throttle stops being applied.

Well, you live and learn
As above it is correct as in neutral the ecu keeps fuel travelling to the engine engine keeps the revs up to idle (around 800 rpm) to avoid cutting out whereas when coasting in gear you drop revs but the auto will change down if it drops too low (which never happens going downhill)
Does it smart coast like the Porsche Pdk?
I thought the Pdk also disengages drive so that there is no engine braking during coasting phase - although that was maybe the Pdk gen1 ?
Nb. On my old commute, I used to get about 4-5more mpg using in neutral method, as there were a few pretty long stretches of low downhill gradient that you could coast, however, if left in gear would slow car down enough to warrant hitting the gas.

According to some posts online coasting exists on Eco Pro mode but is not engaged in conjunction with Cruise. Some people say that Coasting puts the car into neutral but this makes no sense based on mine and other replied above. Also if I come to large inclines I tend to turn off the cruise to avoid major power boosts. Downhill unless its significant I do the same.
Im struggling to find accurate info on this so I might just have to experiment further. However in the long scheme of things there arnt enough inclines & declines on my normal routes to warrant a major difference..

Nice 6 bluestreak
Thanks Inkey, its actually a 4 though
Good to see you back!That is stunning mpg and I am happy with around 40 out of a 640d and I am yet to see much better though, but I have read many times that both the 335d/435d deliver far better figures from the same engine and I would love to know why for sure.sars said:
I believe they are all of a similar weight and I know a 335d touring is only 45kg lighter than a 640d Coupe so it is interesting stuff, I have fuel economy envy...sad I know but that's really why we buy a diesel in the first place!

Maybe the answer is not to drive everywhere in Sport +
.....oh and my convertible weighs in at a giddy 1925 kg, though it feels lighter, the Merc felt very front heavy in comparison
I think that's where I am going wrong sars!sars said:LeeZ4MR said:That is stunning mpg and I am happy with around 40 out of a 640d and I am yet to see much better though, but I have read many times that both the 335d/435d deliver far better figures from the same engine and I would love to know why for sure.sars said:
