For the 2013 DB9, Aston has revised its long-serving 6.0-liter V12 with new cylinder heads, intake manifold, throttle bodies and fuel pump. The result is an increase in output from 470 horsepower to 510 and from 443 lb-ft of torque to 457. Outside the engine bay, the new DB9 gets a more angular grille inspired by the One-77, zinc air vents on the hood, bigger trunklid spoiler and more aggressive lines in between, with LED turning indicators integrated into the side vents. The interior has also been enchanced with new leather, trim and glass switchgear. The new DB9 is being launched at the Paris Motor Show in both coupe and Volante convertible, starting at $185,400.
