In cooperation with the Swiss watchmaker IWC Schaffhausen, Mercedes-AMG has developed an exclusive model known as the CLS 55 AMG “IWC Ingenieur”. Only 55 units of the unique four-door coupe will be produced. The car has a powerful AMG 5.5-litre supercharged V8 engine and boasts exclusive equipment details. The design of the newly designed AMG instrument cluster is based on the new “Ingenieur” watch family from IWC, which is making its world debut at the Geneva watch show in April 2005. The 55 units of the CLS 55 AMG “IWC Ingenieur” will each be customised at AMG in Affalterbach, Germany, and the first deliveries will be made in autumn 2005.
