The Arnage Drophead Coupe show car hints at a possible future production vehicle. The Arnage convertible would succeed the Azure convertible that was dropped in 2003. The show car is based on stiffened version of the Arnage's chassis. Power is provided by a twin-turbo 6.75L V8 that produces 450hp and 645 lb ft of torque. A fully-automatic canvas top retracts in 25 seconds. As can be expected, the interior is finished in plush leather, wood and chrome.
