The first product from Aston’s ‘second century’ expansion plan, the DB11 features a new engine and body structure, fresh styling, improved packaging and motorsport-derived aerodynamic features. The front-engined, rear-wheel-drive grand tourer can be ordered now, priced from £154,900.
NEW V12 ENGINE
Perhaps the stand-out feature in this most significant of new Astons is located under the one-piece clamshell bonnet. Designed and built in-house by a team led by chief powertrain engineer Brian Fitzsimons, the new twin-turbocharged 5204cc V12 is the most powerful unit yet fitted to a DB road car.
Its 600bhp and 516lb ft outputs are sufficient to accelerate the DB11 from zero to 62mph in 3.9sec and on to a top speed of 200mph. It’s also the first series-production Aston Martin to use a twin-turbo unit. The DB11 doesn’t have a synthesised system to augment the engine noise.
The new engine sends its power to the DB11’s rear axle via a ZF eight-speed paddle-shift torque-converter automatic gearbox. The car features a mechanical limited-slip differential with active torque vectoring, the latter a being first for Aston Martin.
Aston hasn’t revealed official figures, but it is targeting a 20% improvement in fuel efficiency and CO2 emissions over the Aston Martin DB9. That should equate to combined economy of about 24mpg and CO2 emissions of roughly 270g/km. Key to that dramatic improvement is a host of technology including variable valve timing, stop-start and intelligent bank activation, which shuts down six cylinders during periods of light throttle usage.
Aston set its engineering team the target of creating a body structure that is lighter, stronger and more space-efficient than the one that underpins the DB11’s predecessor, the DB9. Using a mix of new bonded aluminium pressings, extrusions and castings, the structure “sets new standards for mass versus stiffness”.
