hi all

currently got a bmw e65 745i and currently got it up for sale.

Im now looking for a diesel, something thats good on fuel

what are the rea life figures?

 

[timskemp]

Driving style dictates it, but some see >50mpg on runs, others see <30mpg in town. I drive quite hard and average about 35mpg overall, 40+ on the motorway, 25-30 in town.

 

[MUGGY]

I average 38.5 overall. 42-44 on a run max. speed 80 mph. In town it varies between 20 - 28.

Normal driving I tend to get 37mpg combined.

I've had the car to 49.7mpg on a 30mile run cuising at 70-75mph

Wholly crap !! I've only managed 42 mid trip. By the time I've fannied around through few sets of lights etc it always drops. There must be a remap in your car or similar to achieve those figures?

Round town I tend to get between 30-33mpg, stop and start kind of driving.

Yes the car has had a good West-Tuning re-map, it's driving really great now..

Phew, I thought as much. Can you back up the computer claims with tank to tank fill up calculations? Most remaps 'con' the computer to reporting false info.

The trip computer is not 100% accurate in the first place..

but i did the calculations and with the remap it's 4mpg better off than standard.

I can tell there is a slight improvment with the remap, everything about the car is great now, pulls from no rev so much torque on tap (412ibft)

Buy a BMW E60 525d or 530d 60ish mpg on a run 50ish mpg around town from either engine, also very mappable I'm afraid when it come to diesels MB just aren't in the same league as BMW

Having just committed heracy, I'll now go and put on the flameproof suit

Disagree, drove a 730d and the engine was rough and clattery and not in the same leugue as the V6 MB engine for refinement, linearity and responsiveness.

Depends on the engine, that was probably the old 3 litre engine, the new one in the E60 is smooth as silk you would never know its a diesel. In terms of power there is not much in it between a 320 cdi and a 530d but the delivery on a 530d is much smoother. But in response to the OP question when it comes to real life fuel consumption the BMW wins by a mile.

Yeah coudnt agree more there, I've hurd the new bm's diesel (330D) and I honestly thought it's a petrol engine its so damn smooth... smoother than the V10 M5 when it's cold, lol.
