Not exactly a strong point for a grand tourer, especially since the more ruthless WLTP regulations came into force, the DB11 is a thirsty car on and off paper. The DB11 AMR returns between 18-22mpg on the new 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 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.
