For the 2017 model year, Aston Martin introduced a high performance version of the 2nd Gen Vanquish that was known as the Vanquish S. The S was built in coupe and 'Volante' convertible body styles, and featured a tuned version of the AM29 engine with a power rating of 595hp. In addition to the more powerful engine, S cars were given improved aerodynamics as well as an 8 speed automatic transmission. The 2nd Gen Aston Martin Vanquish S was only built until 2018, when it was replaced by the Aston Martin DBS Superleggera.
