Aston Martin V12 Vantage S arrives – the quickest production Aston ever (video)

The new, more powerful, Aston Martin V12 Vantage S arrives Aston Martin has been teasing something ‘Coming soon’ for a few days, and here it is – the new V12 Vantage S. The new S replaces the V12 Vantage (which we knew Aston Martin had stopped building) and gets Aston’s latest AM28 version of the venerable V12 with 565bhp and 457lb/ft of torque thanks to new engine management, combustion chambers and camshafts resulting in more power and a much flatter torque curve. The extra power has pushed the V12 S beyond the 200nph barrier, with the top speed now 205mph and, we assume, a quicker sprint to 62mph, but Aston Martin aren’t letting on how much quicker the V12 S is.
