The 2015 Aston Martin Vanquish has been revealed

Aston Martin is revealing details of a raft of enhancements to the Vanquish ultimate GT. The new Touchtronic III eight-speed automatic gearbox makes a debut in Vanquish - Aston Martin is improving every major area of the cars' performance. The brand's engineers have worked meticulously with technical partner, ZF, to develop the eight-speed technology and integrate it perfectly into the latest generation of the iconic and much-imitated Aston Martin VH architecture.

These impressive gains not only ensure the cars' exceptional competitiveness in their respective sectors, but also confirm Vanquish as the quickest accelerating series production Aston Martin in the company's 101-year history. Combined with a revised final drive, the ratio changes also mean both cars are, for the first time, now capable of top speeds of 320km/h or above.

A reduction in exhaust gas back pressure as a result of ratio adjustment and other changes also benefits peak power, which rises by up to three bhp to a peak of 568bhp in Vanquish, and two bhp, 552bhp, in Rapide S. Peak torque is up by 10 Nm, too, to 630 Nm at 5,500 rpm in all the cars.

The new eight-speed Touchtronic III automatic gearbox is not only three per cent lighter than its predecessor, it is also packaged more efficiently occupying precisely the same space within the car yet adding two further ratios over the outgoing transmission.

Touchtronic III delivers exceptional shift speed and moves between ratios as quick as 130 milliseconds - far quicker than even the most accomplished racing driver is capable of - while better gearbox efficiency allows more power and torque to be transmitted to the road more of the time.

Gearbox software changes make for a truly comprehensive selection of available driving features such as 'Drive' and 'Drive Sport' modes along with 'Paddle Shift' and 'Paddle Shift Sport' options for more engaging, sporting, shift control.

Away from the gearbox, 15MY Aston Martin Vanquish and Rapide S models benefit from the addition of the latest Bosch Engine Management System. The new system, which delivers more precise engine control and seamlessly communicates with the new gearbox, receives its first application in an Aston Martin that combines the AM29 V12 engine and an automatic gearbox.
