“As an engineer I find the DB11 a fascinating car. One with great depth of character and ability. Of course the V12-engined variant is an icon – an ultimate, if you like, but the V8 is very much its own car.” stated Aston Martin Chief Technical Officer, Max Szwaj. “One with a distinct and carefully crafted character that’s truly seductive. It has been hugely rewarding to put our stamp on this new engine – both in the way it sounds and performs – and to use its impressive attributes as the impetus to reveal a little more of the DB11’s sporting character.

Although the V8 is borrowed from Mercedes-AMG, Aston Martin’s engineers have made several tweaks to it. This includes bespoke air intake, exhaust and wet sump lubrication systems. Also electronic calibration of the V8 engine has included creating new ECU software and reprogramming the engine and throttle mapping.

The V8 is also 254 pounds lighter than the available V12 and Aston Martin’s engineers designed new engine mounts, which together with the bespoke, slimline wet sump system enables the V8 to be mounted as low as possible to optimize the DB11’s center of gravity. Aston Martin says that since the V8 powered DB11 will have more its mass centered within the wheelbase, the it has an increased sense of agility – a quality that has been fully exploited with detailed revisions to the suspension bushing, geometry, anti-roll bars, springs, dampers and ESP software.

The 2018 Aston Martin DB11 with the 4.0L V8 will be priced at $198,995 when it arrives later this year.
