Real world mpg - B4

Rustyfrog · Nov 2nd, 2022, 21:06

Would appreciate any real world mpg figures from XC40 B4 owners.

I have just test driven one and have to admit I am very impressed, and it is under consideration as the next motor.

The combined figure given is 40 mpg.

As I don't have one but do know what's physically possible the golden rule is 22% the official figures.

Here's my estimate

Steady 60 mph clear road 44 mpg

Normal 70 mph clear road 36 mpg

Urban two figures, normal time 25 rush hour 21 mpg. This might not work and could be as good as 30 over 28 if the battery power assists, I forgot that hybrids work best at urban use. I also haven't costed for depleted battery in the two motorway figures so they could drop further.

My overall average is 36mpg over 12K mostly highway miles. We use the car for out of town longer trips - so almost zero urban driving. Expect 38-42mpg on B roads, and 40+ in urban - what SnineT said, mild hybrids really excel in stop and go driving - and from my experience also in uphill/downhill type driving (I was getting 43mpg on highways in Austria this spring..). For safety reasons (hydraulic braking) the engine kicks in on serious declines (eg. downhill driving in the Alps..) so mpg is not as high. I use 98 in it even though it can take 95 - but 95 in France is not that significantly cheaper + it is diluted by 10% Ethanol (vs. 5% in 98) - but I’d expect same numbers on either 95 or 98.

My B4 with AWD is returning 39.2 mpg average with anything up to 44 mpg on longer distances. Car has covered just over 10,000 miles.

I meant to say 22% off of the official figures earlier.

Hybrid is very difficult to call simply due to how often the battery is able to assist, I would say to use Haldex and Caradoc's figures as reasonably what you should expect.

Thanks folks.
We have got to the stage/age where we are doing a lot more short journeys these days, which we all know is not good for diesels.
I love my V90, but somewhat reluctantly, it is time for a change.
Unless someone will volunteer to slap a petrol engine in it for me!

My XC40 AWD Auto is returning 27.9mpg which is nowhere near what I expected, when reading up before I bought the car 35>42mpg was stated ?

How much is start stopping around town and if you reset, what do you get on the motorway?

Macca64 · May 22nd, 2023, 15:25

It’s sometimes best not to look!
