Aston Martin V12 Vantage S Roadster arrives with 565bhp – the quickest Aston Roadster ever

The new Aston Martin V12 Vantage S Roadster arrives The Aston Martin V12 Vantage S – revealed in 2013 – has lost its roof and turned in to the quickest open-top car Aston Martin has ever produced. The Aston Martin V12 Vantage S Roadster gets the same 5.9 litre V12 as the tin-top model, which means a 0-60mph of 3.9 seconds (0-62mph 4.1s) and a top speed of 201mph, both figures just below the coupe but enough to make this the fastest production Aston Roadster ever. The V12 engine also offers delicious lumps of torque, with 457lb/ft – and most of that available almost from tickover – all delivered to the back wheels through the Graziano 7-speed automated manual ‘box.
