Bentley Bentayga review – the ultimate luxury SUV? - MPG and running costs

Bentley's first SUV is sure to be a sales hit, but its sheer weight limits the appeal as a drivers SUV

Evo rating
RRP
from £135,800
  • Immensely capable, W12 and V8 diesel options both immensely rapid
  • Very heavy, and not really able to shrug it off... and just look at it...

MPG and running costs

The Bentayga is predictably costly to run. Everything – from premium petrol to the first-rate servicing it requires – costs extra, but that’s not really a problem for most Bentley owners, is it? Very few of these cars will be bought by penny pinchers, and so owners will be willing to pay whatever it takes to keep their ultra-luxury SUV in fine fettle.

Fuel economy will be an alien phrase to most Bentley buyers, but owners of the W12 can expect mpg figures in the late teens in real-world driving – compared to Bentley’s official figure of 21.6mpg. CO2 emissions are a similarly hefty 296g/km, which is enough to put the Bentayga firmly in the highest road tax bracket. That means you’ll have to shell out £2000 in first year road tax, and then £140 a year thereafter – plus a further £310 for the first five years owing to the high list price.

Opt for the diesel and things become rather more palatable. A combined fuel economy figure of 35.8mpg is positively frugal, while CO2 emissions are two bands down on the W12 at 210g/km – attracting a £1200 first year road tax fee. Regardless of engine, the Bentayga slots into the top Group 50 for insurance – though we suspect most owners will have these garaged, which could keep premiums reasonable.
