Aston Martin DB11 review – MPG and running costs
Efficiency is not the DB11s strong point, economy ranges between 18-24mpg on paper. Which you’ll struggle to match on the road
Fuel consumption is never a strong point for any traditional grand tourer (especially since the more ruthless WLTP regulations came into force), and the DB11 is no different – this is a thirsty car on and off paper. The DB11 V12 returns between 18 and 22mpg on the WLTP cycle, dropping fiercely into the teens when pushed. CO2 has also been reduced, dropping to 270g/km, although the DB11 still occupies the top tax bracket.
The V8 model can lift this up to 24mpg, which is a realistic figure only for gentle motorway driving.
The realities of Aston Martin ownership may not be cheap, but then it is not really any worse than competitors, with the Bentley Continental GT Speed still only registering a similar 18-22mpg. Servicing, too, will be relatively expensive if you’re trading up from something a little less grand. The V8s are marginally more efficient, registering a (broad) 21-26mpg on the WLTP cycle, but settle on a motorway cruise and mid-to-high 20s is possible
