The http://astonmartin.com/”>Aston Martin DB9 was first introduced in 2004 and, since then, it has remained largely unchanged. But today’s buyers will see some changes to the DB9, both in its look and, more significantly, in its power. Beginning with an upgrade to its 6.0 liter V-12 engine resulting from a revised design, enlarged throttle bodies, and a new fuel pump and intake, the DB9 now can claim 510 horsepower to its name–a boost of 40 horses–and a 14 pound-foot increase in its torque, which is more than enough to distinguish it from its predecessors. Styling changes for 2013 include a more pronounced rear spoiler, smoother curves around its body, and a new 5-spoke grille out front fitted while the interior now comes standard with leather. You’ll be paying for this luxury, of course, with a starting price of around $185,000. Both a coupe and convertible version will be available from their initial launch scheduled for November.
