Drop-top uses same 5.2-litre V12 as the coupé, making 600bhp and 516lb ft of torque
The Aston Martin DB11 Volante has been spotted winter testing ahead of going on sale in spring 2018.
The test model looks identical to the “lightly disguised engineering car” that was shown by Aston Martin earlier this year (see bottom picture). An insurance database check confirmed it is running the same twin-turbo 5.2-litre V12 as the coupé, making 600bhp at 6500rpm and 516lb ft between 1500 and 5000rpm.
The DB11 Volante could also launch with a twin-turbo 4.0-litre V8 from Mercedes-AMG, which is due to be introduced to the Aston Martin range next year in the successor to the V8 Vantage before joining the DB11 range. Producing between 500 and 550bhp, the engine is currently used in the Mercedes-AMG GT.
