Another supercar will soon be roaring along the congested streets of Asia and this one makes a lot of noise. It doesn’t come cheap either with a starting price from £140,000 RRP (UK price)

Aston Martin yesterday revealed the DB9 GT – the luxury British sports car maker’s most compelling production ‘DB’ to date. Designed to offer the best of what DB9 can be, the new car delivers world-class grand touring and hand-built excellence.

Claiming the title of the most potent DB9 yet devised, by virtue of its uprated 6.0-litre V12 engine which now boasts 547 PS – the DB9 GT makes its public debut as part of Aston Martin’s impressive presence at this week’s Goodwood Festival of Speed in the UK.

Aston Martin CEO Dr Andy Palmer said: “The arrival of 16 Model Year (16MY) cars, as well as the addition of the sophisticated DB9 GT, gives us our most compelling sports car line-up to date as we continue to build our strongest ever global offering.”

Fundamental to the new DB9 GT’s unique appeal is its uprated 6.0-litre V12 petrol engine, which is capable of generating 547 PS at 6750 rpm, and 620 Nm of torque at 5500 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 62 mph in 4.5 seconds, and on to a top speed of 183 mph.

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 personalisation.

Offering AM, FM, DAB and SDAR reception (US only), USB ports, Bluetooth audio streaming the system delivers superb connectivity and entertainment simply and easily.

A broad array of options inside the DB9 GT include various centre console finishes such as Ice Mocha and Copper Cuprum, while other interior options include Duotone leather seats, door inserts and head linings; and a One-77-inspired steering wheel design.

Aston Martin Chief Creative Officer, Marek Reichman, said: “The purity of form and proportion, together with a lithe powerful, stance, remain at the core of what the DB9 is to look at. With these changes, we have made the DB9 GT yet more stylish, while retaining its unmistakable and globally renowned identity.”
