Hi Guys

We bought a highly specced 2018/2019 V90 T4 estate a few weeks ago and having just returned from a winter holiday in France I have been shocked by the less that 30 MPG the car has returned on what was mainly motorway driving. This cant be right. I am about to contact the dealer to get it looked at but was wondering if anyone else has had a similar problem?

Apart from this issue the car has been great

Depends really - were you full of passengers and luggage at 130/140km an hour for most of it?

Shoving that much car and weight at that speed will hit mpg quickly

yeh as said, depends on the load of the car ... tire pressures, are you running winter tires? your driving style etc etc

But if it helps, I have an S40 T5 and get over 30mpg easily.

I've got a V90 T5 CC (AWD) and get 27 mpg normally on short journeys, but up to 37 mpg on a long run. That's running at 75 mph using Pilot Assist.

On a long run mine will average 41 MPG, mine has done 21,000 miles and running really nicely.

On my commute I’m lucky to see 31 MPG, it’s a really thirsty engine.

My v90 t4 doesn’t average much more than 30 so if you have been pushing on it sounds about right.

T4 V90 here run from new

Until it hit 4000 miles fuel consumption on motorways was awful - think 30mpg at 70mph +/- 10%

It now does 40mpg four up with luggage and Im happy with that

The car was cheap to lease so it wasnt particularly the extra cost of fuel but the limit on range which annoyed me

Cheers

Restarting this thread if I may as we have a 20 plate V60 T43 which I believe is the same 187bhp B4204T44 engine all be it in a slightly smaller shell.

The V90 is listed as 33.2 - 37.7 mpg on parkers, and the V60 as 34.4 - 38.7 (used the Momentum Plus Auto for both) so broadly comparable. These are the newer 'WLTP' figures which appear to be a bit more realistic/pessimistic than the older figures.

Therefore surprised that I too basically cant get it above low 30's, even cruising gently with a decent mix of motorway, keeping the speeds reasonable its still only doing 32ish. If driven even remotely spirted on the same roads its down to 29mpg, 27mph even, which is then almost worse than my 20yo 3 litre 230bhp E46.
We should have got the D4 (46.3 - 52.3 book mph) but we wanted a nice spec, adaptive cruise, avoid the r-design suspension and seats, and the engine ended up being the comprise, and you don't get it all over your hands every time you refuel.

Appears to been in good health and has full service history, but interested if there is anything we should look at.

Failing PCV get a mention in a few places, but more for a high pitch squeal than poor mpg.

TBH, I have no experience of your particular car but I would think that 30 ish from a reasonably large estate with a 2 litre turbo-charged petrol engine would be about the going rate.

Well, I have done some tests and crudely characterised the MPG of the Volvo at various motorway/dual carriageway speeds, as graphed below and compaired with similar data from the BMW 330ci

Obviously one is winter one is summer, and it was lightly raining for the Volvo, but otherwise both cars where warm beforehand, mpg taken with a rolling start, broadly flat ground and an out and back.

Why do you get (diesel) all over your hands every time you refuel?
They have disposable gloves.
I’ve never got it all over my hands.
I doubt most do…

Are thr mpg figures taken from the car telling you its average or a propper fill up check ?

Gloves run out, gloves rip, you forget because your in a rush and your car is petrol.

Should have said, but they are both from the cars onboard computers, as its the only option on what is ultimately a very short run.

The BMW onboard computer is is around 1mpg optimistic compared to brim-to-brim data. I don't know how the Volvo fairs.

First good long road trip in the car, Wirral to Edinburgh, up on the Friday back on the Monday.

Reset the MPG as we left the house, clocked an average of I think 43mpg on the way up, predominantly acc on at 68mph, up the M6 and then across on the A702 which overall I cant complain about.

Two days of local driving around the city dropped that to 38-39 average and then we drive home and finished at a reading of 40.7mpg over about 600 miles.

Almost more importantly, it was a lovely place to be, comfortable and quiet. The adaptive cruse control works very well.

Dutch have you done a propper calculation, or are they all just what the car states ? I don't believe any mpg shown on car dashes to be honest .

Be interesting to get a true reading. I can't see it being any worse than any other 2l turbo petrol.

It's a heavy car and the engine needs to work hard to pull it along basically.
I've got an S60, albeit with the more powerful T5 engine in Inscription plus spec.
Around town I get mid 20s, long cruise on a motorway or decent A road and I'll see mid 30s through to low 40s.
Average is about 32mpg with mixed driving.
