Real world MPG for 635d Sport

[Coneyhurst Blue]

The advertising says 40.9 MPG.
What does the real world say ?
I know alot will depend on driving style etc but as a guide what could one expect ?
Cheers all !

My pre LCI 535d does 32-33 MPG. A colleagues LCI version (with similar mix of driving) does around 36 MPG. 6 series will be the same save for some very small possible variance.

My 730d does 33mpg on average. Averaged 40 mpg on long trips to southern France and back (from Scotland).

If you do a lot of "urban driving" the MPG plummets. I live in London and had one of the first 535d's and now run an X5 SD (same engine)....great on a motorway but stop start traffic kills them. I reckon you'd be doing very well to see mid 20's in town. I have no idea how BMW calculate their MPG's but I can't get close to what BMW claim even if I am doing a very gentle 50mph.

335d coupe does 40-42mpg over a tank.

High 30's booting it over a tank or shorter journeys. Don't do short journeys and town traffic is minimal.


...
What toxic said applies to me. I only really use my car for a daily commute which is steady traffic, rarely getting above 55mph. Avg. speed is 32mph and steady flow for 20 miles with a few miles of stop start town, rest is a-road with a few roundabouts. On the a-roads the mpg needle is fixed at 50mpg. So with slowing down which uses no fuel i quite easily get 42mpg over a tank.

It's a good point. Mine drops very significantly in heavy traffic.

Our E70 is way worse than our E60 (same engines) even allowing for weight, 4 wheel drive etc. 10 MPG difference overall.

Just realised we exchanged PMs when I bought the E70 for the OH - you were right - great cars!!

A colleague gets just under 35mpg long term average from a pre-LCI 535d so I would expect a very similar figure from a similar age 635d and a little more from a recent model.

So we did! Yeah we'll be keeping ours for a while....probably until the next generation X5 comes out which is probably three years away.

Nowt else I really want that can do the job we need it and do it better....we specced ours up with every bell and whistle when we bought it so it wasn't cheap.....

I've been very happy with mine. Every day use, a mixture of town and country roads It gets about 36mpg.

[S8QUATTRO]

34-38 mpg mostly mway...better economy when using the paddles instead of full auto

[Mike335i]

Surprisingly not much more than the 335i then, my petrol gets mid 20s in town and up 35 on a steady run.

335d, 44 mpg overall, probably more on a steady run, but I only measure actual overall (i.e. not using car computer)

[jayx73]

2010 635d. 33 around town mainly 10 mile trips 40on a run can creep upto 44 if I stay below 80

[Boyblue2]

I also have a 2010 635d coupe. This time of year with cold weather I average about 35 mpg a mix of long (20+ miles) and short journeys, in better summer temperatures on long journeys (100+ miles) anything upto 45 mpg.
Large diesels take longer to reach operating temperature than petrol engines. Much depends on how heavy your right foot is.

Fantastic motorway cruisers and right now great value. I’ll be sad to sell mine because the interior quality and comfort is excellent. Replacing with a newer 335d xdrive which is quicker, more economical etc but the indside is not as nice imo.

[rayyan171]

X5 with the same engine gets 25mpg combined. They get 35 city and can see 47 on the motorway with cruise on. They can even edge 50mpg. Very economical car, which complements the performance they offer.

[S8QUATTRO]

40k miles done - 2009 635d - remapped - averaged 36mpg 85% motorway driving

[village24]

Theyre a bit of performance bargain as they've depreciated loads now.

Had an lci 635 which I think was remapped prior to my purchase, did thermostats and swirl flaps etc and general maintenance but never saw more than 42 on a good motorway run. 35-40 was the norm

[S8QUATTRO]

Definitely a bargain for the quality and performance. I’m sure they are starting at £4K now…must have been a £50k-£60k motor when new, if only mine had the better leather
