Under the bonnet, the GT features an upgraded version of Aston Martin's 5.9-litre V12. Outputs have been increased, with maximum power now rated at 402kW at 6750rpm and torque topping out at 620Nm at 5500rpm. That's up 22kW over the current model, although torque is unchanged.
With that extra mumbo, the GT is said to be capable of a 0-100km/h time of 4.5 seconds and a top speed of 295km/h, which makes the GT 0.1 second faster to 100km/h.
Externally, the GT is distinguished by 20-inch alloy wheels all around, new badging, reworked head- and tail-light graphics, black anodised brake calipers, an engraved aluminium fuel filler cap, and a black front splitter and rear diffuser.
On the inside, the centre stack has been redesigned with touch-sensitive climate and infotainment controls. At the top of the dash is the company's upgraded AMi II infotainment screen, which is said to have a more streamlined menu structure, digital radio compatibility, and greater customisation options.
There's also an Alcantara steering wheel for the coupe and GT embroidery for the seats. The new DB9 GT is available for order now, but deliveries won't begin, at least in Europe, until the third quarter of 2015.
Aston Martin has also upgraded its Vantage and Rapide S models, with trim fiddles, as well as the AMi II infotainment setup and touch-sensitive centre stack controls.
