BMW has revived its iconic CSL badge, reserved for its lightest and most high-performance track cars, with the reveal of the new M4 CSL.
The badge, which stands for ‘Competition, Sport, Lightweight’, means this special edition of the M4 has undergone an extensive weight reduction programme.
The German brand has also fitted it with the six-cylinder engine from the M4 GT3 racing car, to give the road-going version a power hike.
The 3.0-litre unit makes 542bhp and 650Nm of torque, sending power to the rear wheels through an automatic transmission, contributing to a 0-60mph time of 3.5 seconds.
Huge weight saving measures came from the introduction of carbon-fibre bucket seats, which are 24kg lighter than the standard front seats.
A further 21kg was saved by removing the rear seats, while another 21kg was shaved by fitting carbon-ceramic brakes and special light-alloy wheels, springs and struts.
Reducing soundproofing and switching to lightweight sound insulation saved a further 15kg, with another 11kg trimmed through extensive use of carbon-fibre-reinforced plastic for the roof, bonnet and boot lid.
A lighter exhaust system and other details shaved a further 8kg, bringing the total weight saving to 100kg.
As standard, the M4 CSL comes painted in an exclusive Frozen Brooklyn Grey paint job that offers exposed carbon-fibre surfaces and red accents, while white and black paints are available as an alternative.
An optional upgrade is BMW’s Laserlight headlight technology, which shines yellow to evoke images of the firm’s endurance racing cars. The LED rear lights are fitted as standard and have an intricate illumination design.
With all these upgrades focused on improving track performance, BMW has naturally sent the M4 CSL around the Nurburgring Nordschleife, achieving a time of seven minutes 15.677 seconds.
The BMW M4 CSL will cost from £128,820 in the UK and is on sale now.
The CSL badge was first introduced on the 3.0 CSL in 1973 based on the touring car racer, and was revived the the E46-generation M3.
This M4 marks only the third time the name has been used.
