Munich-based leather goods manufacturer Etienne Aigner has teamed up with Mercedes-Benz tuning specialists Carlsson to develop the Carlsson Aigner CK65 ‘Eau Rouge’. The limited edition luxury coupé – based on the Mercedes-Benz CL – has a 0-100 km/h time of just 3.9 seconds.

Named after one of the most famous race-track curves, the Eau Rouge in Spa Francorchamps, the interior features a combination of Aigner leather and Aigner Alcantara. It includes an ergonomically designed sports steering wheel in leather and Alcantara or leather and wood.

Other luxury features include a navigation system, hifi system, two-piece 21" aluminium wheels, carbon-fibre aerodynamic parts and C-Tronic suspension.
