Yesterday BMW revealed a one-off BMW M5 CSL at Nürburgring to celebrate 25 years of M5. The cas is based on the current generation M5 and is described by M division’s head of development, Albert Biermann, as “the M5 CSL we never built”.

Displacement on the 5.0-liter V10 has been increased to 5.5 liters. No word on the official performance numbers, but Mr. Biermann hints at around 580 horsepower and near 400 lb-ft of torque. Stock M5 for comparison has 507 hp.

Stock gearbox has been replaced with the beefed up version of the M3’s seven-speed double clutch gearbox.

Overall weight has been decreased by 50 kg thanks to carbon fiber rood and stripped down interior. There are no back seats and in the front we have now two carbon fiber seats.

No details about the 0-60 mph time nor top speed, but we do now the M5 CSL lapped the Nürburgring in under 8 minutes, 20 seconds faster than the regular M5.
