Aston Martin unveils its latest Vanquish model with some significant updates under the hood. They include a new transmission, taking the form of the Touchtronic III eight-speed automatic gearbox, appearing for the first time on the car's transaxle layout. Reprogrammed Bosch electronics, coupled with the new transmission, nets a 3-horsepower increase, bringing the total power output to 568 hp. The upshot: a 0-60 sprint time of just 3.6 seconds and a top speed of 201 mph. Further upgrades include the addition of lightweight 10-spoke alloy wheels, and new exterior paint and leather trim options. Check out more looks and a video overview below.
