Aston Martin has revealed the DB9 GT, the most potent 'DB' ever made.
Fundamental to the new model's unique appeal is its uprated 6.0-liter V12 petrol engine, which is capable of generating 547 hp at 6,750 rpm, and 457 lb-ft (620 Nm) of torque at 5,500 rpm.
The all-alloy, quad overhead cam, 48-valve 5,935 cc front mid-mounted V12 is mated to the proven rear mid-mounted Touchtronic II six-speed transmission with electronic shift-by-wire control system. It carries the British luxury sports car maker's core GT offering from rest to 60 mph in 4.4 seconds, and on to a top speed of 183 mph.
The independent double wishbone suspension all round continues to deliver secure handling while the three-stage Adaptive Damping System (ADS) offers distinct Normal, Sport and Track modes for the broadest possible breadth of dynamic characteristics.
However power is only part of the story, as the new Aston Martin also includes important and far-reaching equipment changes which underline its position as the best DB9 to date.
Most notable among the interior equipment updates is the arrival of the AMi II touch-sensitive Aston Martin infotainment system. While AMi debuted on the range-topping Vanquish at its launch, AMi II offers a revised menu structure which makes using the system even more user-friendly.
Building on the system launched in the Vanquish, the DB9 GT's AMi II infotainment package sees key improvements made in a number of areas including text message integration, vehicle status information and extended background themes for greater personalization.
