You'll have to look closely to see the differences between the 2012 Aston Martin DBS and the Aston Martin DB9, but the most obvious is clearly the nearly $100,000 price difference on the window sticker. The DBS and DBS Volante's extra cost actually buys less car, which in this case is a good thing. Compared to the DB9, the DBS is 50 pounds lighter but its 6.0-liter engine pumps out more power, rendering a lower 0 to 60 time and faster top speed. Beyond its higher position in the Aston Martin pecking order, the 2012 DBS offers more available features including the new Carbon Edition model and a manual transmission something the DB9 no longer offers.
