The Aston Martin DB9 is powered by a 6.0-liter V-12 engine that has 470 horsepower and 443 pounds-feet of torque. There are two transmission options: a standard six-speed manual gearbox and an available Touchtronic II six-speed automatic. Standard features include 19-inch alloy wheels, automatic climate control, heated leather power seats with memory, six-disc audio system with navigation and satellite radio, Bluetooth wireless connectivity, and parking sensors. A wide variety of wheel designs, paint colors, wood trims and interior trim colors can be specified. A thirteen speaker, 1000-watt Bang & Olufsen BeoSound audio system is available. The optional Sport Package includes 19-inch forged alloy wheels, revised shocks, up-rated springs, re-tuned front stabilizer bar, revised under tray and lowered ride height. Styling changes freshen the DB9's appearance, with a new front bumper, bright finish radiator grille and a re-shaped lower intake featuring bright hexagonal mesh, new headlight bezels, re-styled sills, 20-spoke diamond turned alloy wheels and clear rear light lenses. A new adaptive suspension system provides enhanced ride comfort together with sharper handling when switched to Sport mode.
