MPG and running costs
Not exactly a strong point for a V12 grand tourer, the DB11 does at least promise a small improvement in efficiency compared to Aston V12s of old thanks to its all-new downsized 5.2-litre engine. The new DB11 returns a slight increase in MPG on paper, averaging 23mpg compared to the DB9’s 19.8mpg, but we would bet meeting that number will be unlikely once you begin to tap into the car’s performance.
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 combined 19.8mpg. Servicing too will be relatively expensive if you’re trading up from something a little less grand.
