Dubbed Touchtronic III by Aston Martin's marketing department, the ZF eight-speed automatic gearbox will be fitted as standard on all MY2015 Aston Martin Vanquish and Rapide S models.

Joining the new auto box in the revised Vanquish and Rapide S are a series of changes to the company's V12 engine. These include the latest engine management controller and a reduction in exhaust back pressure.

As a result power is up 2kW to 424kW in the Vanquish, while the Rapide S gains 1kW for a total of 412kW. Torque in both cars has been boosted by 10Nm to 630Nm.

The extra gears, and additional power and torque, have naturally improved the performance figures of both cars. With these changes the Vanquish can now complete the 0-100km/h sprint in 3.8 seconds instead of 4.1 seconds, while the Rapide S is capable performing the same feat in 4.4 seconds, down from 4.9 seconds. According to Aston Martin, both cars are now capable of hitting speeds over 320km/h.

Under the EU testing regime, the new cars are said to be around 10 per cent more fuel efficient than before, with both the Vanquish and Rapide S now said to consume 12.9L/100km.

In other changes, the Vanquish has been fitted with a stiffer front and rear suspension setup, while the Rapide S gains larger front brakes. Both vehicles are now equipped with stiffer rear suspension bushes, and can be ordered with ten-spoke forged alloy wheels, which are around 7kg lighter than the standard alloys.

On the inside, a selection of new colour schemes is available. These include a blue/black layout dubbed Dark Knight and, if you're game, a "bold" pink interior.

The revised Vanquish and Rapide S will start rolling out to showrooms from the third quarter of 2014, but aren't likely to reach Australia until 2015.
