The "Sportshift" automated manual transmission benefited from a software update, while a lightened flywheel was introduced for both the manual and the Sportshift versions. Aston Martin also stiffened the suspension and the suspension system now uses Bilstein dampers. An optional sports pack was offered with stiffer springs for better handling and all-new 5-spoke alloy wheels. Sportshift-equipped models also received a new dual throttle mapping update which allows the driver to choose from the default sport mode, or comfort mode, which gives more comfortable shifts and throttle input for drivability. Combined European fuel economy and emissions are also improved by 13%. For the 2012 model year, Aston Martin replaced the 6-speed Sportshift with the 7-speed Sportshift II first utilised in the V8 Vantage S.
