. one-off BMW .5. CSL was unveiled at the company’. Nurburgring workshop. The prototype is . unique . Division example that forms part of the .5 brand’..25th anniversary celebrations.
The big news is the engine which was modified from the factory 5.0-litre .10 to . larger 5.5-litres via increased stroke, making it . Division’. largest ever. Modifications include . carbon fibre manifold with an increased capacity air box and secondary oil cooler. As . result another air duct was created on the front bumper to accommodate it.
One way to qualify as . CSL (Coupe Sport Lightweight) is to shed body mass, which this one did… carbon fibre roof was employed and some interior parts stripped down. For example standard front seats were replaced with carbon fibre units and the rear one removed completely… total weight saving of 50kg was achieved. The suspension was also slightly modified but kept close to standard.
Long-time BMW race driver Claudia Huertgen has taken the car around the ‘Ring and claims to have posted . sub-8 minute time.
Official figures were not released but . division’. head of development, Albert Biermann told Autocar that something around 580bhp (433kW) and 400 lb-ft (542Nm) could be expected. It is sent to the rear wheels via the double clutch .-DCT 7-speed gearbox. The power figure sounds close to what is speculated for the next-generation car.
“Right now we’re concentrating on the next-generation .5,” Biermann said..”This car has been fun to develop but there are no plans for production.”
