V12 Vantage vs. V12S Vantage Power
Discussion
From the PistonHeads buyer’s guide of both variants:
“ in spring 2013 a new model based on a revised AM28 version of the 5.9 stepped in to extend the V12’s life – and its performance – in the purposeful guise of the V12 Vantage S. The AM28 was the same capacity as before, with the usual 6.0 on the cover despite the actual displacement being nearer to 5.9, but all the major bits – cylinder block (with machined combustion chambers), crank, valves, springs, pistons, intake manifold, higher compression head, hollow camshafts – were new, as were the oil and water pumps and the Bosch engine management system.
With re-jigged airflow to improve cooling plus new dual variable valve timing, the S generated 563bhp at 6,750rpm. Its torque curve was fatter than the V12 Vantage's right through the rev range, with 457lb ft peaking at 5,750rpm and (Aston claimed) 376lb ft at just 1,000rpm, a useful extra 52lb ft at that point.”
