Diesel MPG

Trip computer is around 29mpg each reset. She is on her 3rd tank.

I am pretty sure once motorway miles, or long B road miles are undertaken, then 45+ would easily be seen,(she got nearly 40 from my D5 60) which would be around 50mpg in the comparable diesel?

Interestingly, and I have said this regards XC60 D5 as well that mpg on the computer trip 'instant' readout is generally higher(=better) in 5th gear than 6th

Glad you like your car btw, although I have decided I don't like you anymore as yours is very high spec.....

In comparison, I'd have considered mid 30s-40 as woeful, but that's mainly based on my experience of smaller petrol engines on that particular road. It's very hilly, and to keep momentum you really need to work a petrol hard. The D2 appears to have just the right grunt in gear to save you from having to constantly work the gearing.

On the flat, or on longer main road runs, I'm sure the gap between the two engines would be less but I've had petrol rental cars of all sorts up and down that road and the difference between them and pretty much all diesels is noticeable. Having said that, I haven't tried a petrol V40 so more than happy to be proved completely wrong.

Did the same run in my D4 V60 last night, got a 53mpg result. Not too bad I suppose given the extra weight it has to lug around. Haven't started to use Fuelly on the V40 yet, but regularly resetting the trip computer to get a decent idea of mpg. I'm very impressed with the whole car so far, although I'm still not allowed to use it too often....

Our D2 does 70 odd mpg without really trying to take it easy. Diesel for me every time.
