Hi all, just after a bit of help really, my mum has a BMW 118d which I'm going to be borrowing to do a journey down South to Newton Abbott as it should get better MPG than my Fiesta ZS and be more comfortable for the journey down.

My question is, will the BMW do a round trip to Newton Abbott on one full to the brim tank? Just trying to work out fuel costs as i've never really driven a diesel before, let alone my mums car. Its 266 miles there, so 532 round trip. Car is a 61 plate if that matters? I dont drive over the top and in the interest of keeping fuel costs down i'll drive as conservative as possible!

Any help appreciated.
 
I would have thought so, but why bother risking it. Just chuck an extra £20 when you are there or something?

You might have an easy run up, but get stuck on the motorway in stop start traffic for 3 hours on the way back.
 
You only have to average 48MPG to make it on a tank, which should be more than doable.

Heck, I used to get around that on a motorway run out of a 52 plate, 160,000 mile old 330d.
 
Yes easily.

I used to drive a 318d with the same engine and would get between 650 and 800 miles to a tank with most of that motorway driving.

So unless the 1 has a much smaller tank I'd say you'll be fine.

What brings you down here? :)
 
Driving normally I used to average about 54/55 mpg in the 318d.

My other half managed to get it averaging mid/high 60s on the motorway one trip driving like Miss Daisy.

So you expect it to AVERAGE 66.2MPG?

Behave.

There are several factors I took into consideration

1.The car is a new 118d, mpg figures should be consistent to the manufacturers
2. according to the literature will average 62.8 mpg combined, so a motorway trip should see more mpg.

comprende?
 
I "comprende" that I've given facts, you've given conjecture.

It's unreasonable to expect to average more than the combined cycle figure, unless you are expecting him to set off, on the motorway, immediately at motorway speed, and not have to brake, accelerate, drive to or from the motorway, or stop at any services.

As I've already said, to make it on one tank, in that exact car, would involve a 48MPG average, which is a fact, a more than achievable fact in real life situations.

Guesstimating a fuel spend based on a wishful MPG figure is unlikely to bring anything other than dissapointment.

Capiche?

right o! His journey will be 95% motorway anyway so Its not that 'unreasonable' to expect higher than combined.

A new shape polo 1.6 tdi averages close to what the extra urban figure is on a Journey from Bristol to Clacton. I doubt BMW engines are no less advanced?
 
I have driven many BMW 118'd's. The absolute max I've managed was 54mpg on an exclusively Motorway trip from Worcester to Elsemere Port and return.

Infact the BMW 4 cylinder diesels I've driven (116d, 118d, 120d, 318d, 320d, X1 XDrive18, X3 XDrive20d) have all struggled to beat the combined figure on a Motorway run. By contrast the petrol ones seem to happily manage the Extra Urban figure when taking it easy on the Motorway*


*I know that none of the EU test cycles simulate motorway driving.
 
I managed 47mpg driving from manchester to rainham in a pre-efficient dynamics, pre-efficient gearbox automatic 2007 3l twin turbo 3 series diesel. If you dont manage to beat that massively you're doing something hugely wrong :D
 
Without going too off topic, the issue with the whole average thing is you start off with a cold engine on quiet slow streets. Until you get up to speed and the engine oil warms up fuel economy will not be anything close to optimal.

I'd guess that if you drive sensibly it will be achievable. Just chuck the cruise on at 70, or if you desperately don't want to fill up, 60. Key thing is not to keep blasting up to cars and slamming on the brakes.

How much better would it be with the ED engine stuff and better gearbox? 2-3 Mpg over the same journey?
