Aston Martin‘s ultimate grand tourer sees a modest evolution with the introduction of the 2015 Vanquish. Most of the changes come under the hood as both the coupe and convertible Volante are highlighted by the inclusion of the new eight-speed Touchtronic III automatic gearbox and an uprated AM29 V12 engine. Coupled with reprogrammed Bosch electronics, the new setup gives the Vanquish 568 hp and 465 pound-feet of torque, thus allowing it to sprint from 0 to 60 mph in just 3.6 seconds before hitting a top speed of 201 mph. Rounding out the most notable upgrades are new dampers, which are 15% stiffer at the front and 35% at the rear of the vehicle. Both the 2015 Vanquish and Vanquish Volante will become available in the latter part of 2014 with market-specific pricing and options to be detailed in the near future.
