Long Term Review

Volvo XC90 T8 Inscription long-term test review – sixth report

Cars Editor Andy Pringle is living with a hybrid XC90 to see how effective it is in everyday life. This month, he tots up the figures to see just how economical – or not – the car has been.

First report: August 2016 – Getting used to the XC90 and using it as a family car
Second report: September 2016 – How effective the petrol-electric combination is in everyday life Third report: October 2016 – Long-distance driving and the frustrations of owning a plug-in hybrid Fourth report: November 2016 – Size really does matter Fifth report: December 2016 – Winter temperatures and the petrol/electric powertrain Mileage - 5474 Costs £50 (two puncture repairs)
Whenever people see that I’m driving a hybrid, one of the first questions they ask is what the fuel economy is like. So, after several months with the XC90, it’s time to look back on the fuel log and see just how good the economy has been in the real world.
After all, I have no doubt that one of the big attractions of the XC90 T8 is its ‘official’ fuel economy of more than 130mpg on the combined cycle. Sadly, my news isn’t that great: over the best part of 4500 miles, I’ve only been averaging just short of 36mpg – pretty much bang on 100mpg less than that ‘official’ figure. And, don’t go thinking I’m some kind of weird, heavy-footed lunatic, as a quick scuttle through some online XC90 owners’ forums has shown my figure is very much in keeping with plenty of others’ experiences. There has been considerable variations between tankfuls, though (although, as an aside, I’m not quite sure if I should be referring to a ‘tankful’ when electric power is such a vital part of the equation). And it will come as no surprise that, the more I used the electric motor, the better my fuel economy was.
On my occasional 400-mile round trip to our head office in Manchester, I would only get 30mpg or so, and on a journey of that length, it made precious little difference to the overall economy whether I was able to charge the car while it was parked in Manchester. What it did do was make me feel a little happier as I glided out of the city centre on electric power with zero tailpipe emissions, knowing I wasn’t contributing to the air pollution.
When I was just doing my more regular 20-mile commute between home and our office on the outskirts of South West London, things improved massively. I got an impressive 48mpg from one tankful, and soon became used to getting economy well into three figures on some short journeys. Am I disappointed not to be getting better than 36mpg? I suppose so, yes, although not for a second did I think I’d be able to average anywhere near that official figure. Instead, what these last few months have taught me is that I could probably average the best part of 100mpg if my motoring life was mostly made up of short, suburban journeys, when I would be driving on electric power only. There are circumstances that really suit the hybrid version of the Volvo, but the trouble is they’re not quite my circumstances. With the demands of work and family life, I do too many long journeys for the T8 to make sense – in terms of fuel economy, anyway – over the most obvious alternative in the XC90 range, the D5 diesel.
I know I’m not exactly comparing like with like, but according to anecdotal evidence I’ve found online, most buyers of the diesel XC90 seem to be getting economy in the low 30s. While that’s worse than the hybrid T8, it’s not much worse, and certainly not enough to justify the extra the hybrid model costs to buy in the first place. On balance, if I was choosing an XC90 again, I think I would choose the diesel-engined model.
Had I been a company car user, however, then the T8 hybrid would be a no-brainer. Thanks to its low CO2 emissions in the official tests, it incurs such low rates of company car tax that it’s hard to argue against.
