The V8 Vantage's V8 engine features a bump in displacement from 4.3-liter to 4.7-liter, with a horsepower increase to 420 and torque increase to 346 lb-ft, an increase of 40 hp and 43 ft-lb of torque over the former powerplant. It is mated to a standard six-speed manual transmission or an optional automated manual with paddle-shift, both of which have undergone changes to improve performance and to handle the increased levels of power and torque. Also introduced for 2009 is the optional Sports Pack, which comprises forged lightweight alloy wheels, re-tuned Bilstein dampers with improved dynamic response, up-rated springs and a revised rear anti-roll bar. A new Hard Disk Drive (HDD) Navigation System offers faster route processing, additional features and improved graphics. Full ipod/MP3 integration is retained as standard equipment. Standard safety features include airbags, antilock brakes, traction control and an electronic stability system. For 2009, the acclaimed V8 Vantage design remains unchanged, with only the enhancement of a range of new standard and optional 19'' alloy wheels. Inside, the changes include a new centre console and revised switchgear. A series of improvements are introduced to the V8 Vantage chassis and suspension setup to deliver improved body control and low speed ride quality, enabling the driver to take full advantage of the increased performance potential.
