On January 17, 2006 it was announced that a new Aston Martin DBS would be used in the 21st James Bond film Casino Royale. The new DBS is based on the DB9, more specifically the DBR9 race car. Built on the VH Platform the car shares its roof, sidescreens and wheelbase with the DB9, but sits lower (by 25mm) and wider (by 40mm) than the DB9. Visually, the front end is dominated by air scoops and cooling ducts which help cool the six-litre V12 engine which has reportedly been uprated to produce more than 500 bhp. At the rear are a carbon diffuser and an integrated rear lip spoiler. Other details include a six-speed manual transmission and a removable stopwatch. A special helmet pod behind the driver's seat is present for Casino Royale but will not feature in the production version. Aston Martin is expected to build only 300 examples of the new DBS.
