Jaguar XF review – MPG and running costs

Thanks in part to being constructed from JLR’s uniquely heavy aluminium alloy, these XF’s aren’t as frugal as their acceleration figures would suggest 

Evo rating
from £32,585
  • Sophisticated chassis with superb ride quality; interior design and tech now a real highlight; priced well below rivals
  • Lacklustre powertrains; imprecise transmission; crying out for a performance derivative

WLTP regulations have seen the XF's engine lineup change over the past few years and quoted economy figures have also taken a tumble – though it's important to realise that any such changes have also been suffered by competitors.

At its most efficient, the mild-hybrid diesel is rated at 57-50mpg on the combined cycle, which is a far cry from the 70mpg-odd the original quoted on the old system, but is a few MPG above previous XF diesels. All-wheel drive and Sportbrake models each remove a couple of MPG from the total though, dropping to around 45mpg for an all-wheel drive Sportbrake. In our experience, anything over 35-37mpg feels like a reasonable real-world expectation.

P250 models don’t seem too compromised on paper, rated at 35-31mpg, but the P300, with its bigger outputs and all-wheel drive drops this down to 32-30mpg. In the real world, our experience with the latter powertrain delivered some quite shocking results however, barely troubling the low 20mpg mark on a combination of motorway and fast A-roads. For comparison, on an identical road loop, an F Pace powered by a 394bhp straight-six petrol averaged similar numbers.
