The Vanquish S gets more power, although the increase must be well within the margin of variation of the non-S’s engine. Building on the heritage and success of flagship Grand Tourer comes the beautiful Aston Martin Vanquish S – bringing improved engine power, enhanced dynamics and all new styling to create a car of unprecedented ability. A fractionally freer-flowing intake system aims to sharpen the top end in the 5.9-liter V-12 and takes the output rating up 12 horsepower to 580 hp—still 20 horses less than the new twin-turbocharged V-12 in the DB11. Strangely, Aston claims a higher, 595-hp output for the engine in European spec, although it says the engine is in the same state of tune and offers no other explanation.
