An Aston Martin DB11 equipped with a twin-turbocharged V8 engine will be launched later this year.
The future model's engine is sourced from Mercedes-AMG and is based on the ‘hot-vee’ unit used by the AMG GT. It will produce around 525bhp, which is 75bhp less than the existing twin-turbocharged V12 DB11. Government data confirms this development car testing with a 3982cc engine; the same capacity V8 as is used in the AMG GT.
The V8 comes as part of Aston Martin's deal with Mercedes, which involves co-operating on powertrain development. The 2018 V8 Vantage will also inherit the AMG unit.
The DB11 already features Mercedes' electronic architecture and switchgear, and the same is expected for Aston’s other future models.
Autocar understands that aside from engine development work, the DB11 test car seen here is being used alongside several other V12-engined mules to finalise chassis settings before the first production V8 DB11s are built.
