2023 BMW M4 CSL - Exterior & Interior Design

The stripped-back racing character of the BMW M4 CSL is underpinned by a time-honoured concept that harnesses cutting-edge development expertise and the latest technology to create an enthralling end result. “CSL” stands for “Competition, Sport, Lightweight”, referencing the critical role of weight-minimised design in achieving success in motor sport. The BMW 3.0 CSL developed by BMW Motorsport GmbH according to this same principle won the European Touring Car Championship at the first attempt in 1973. And the M4 CSL is also following in the tyre tracks of successful special-edition models from earlier generations of the BMW M3/M4, most notably the legendary BMW M3 CSL from 2003 and the BMW M4 GTS unveiled in 2016.

For BMW M GmbH, the world premiere of the new BMW M4 CSL at the Concorso d’Eleganza Villa d’Este (20 – 22 May 2022) will be one of the highlights of its 50th anniversary year. Production of the special-edition model will begin – in a limited run of exactly 1,000 examples – at BMW Group Plant Dingolfing in July 2022.

Present and correct in the fundamentals and the details: intelligent lightweight design in the BMW M4 CSL.

Its talent for innovation and racing-car know-how enabled BMW M GmbH to restrict the special edition’s DIN kerb weight to 1,625 kilograms. A standout power-to-weight ratio of 2.95 kilograms per hp (4.01 kg/kW) provides the ideal platform for a dynamically sublime driving experience.

Fitting M Carbon full bucket seats reduced weight by around 24 kilograms on its own compared with the standard seats fitted in the BMW M4 Competition Coupé. 21 kilograms were saved by removing the rear seats and seat belts, integrating a partition and making the associated modifications to the luggage compartment. And chassis changes, including the addition of extra-lightweight M Carbon ceramic brakes and special light-alloy wheels, springs and struts, lowered the figure by around another 21 kilograms. Paring back the amount of soundproofing plus switching to ultra-lightweight sound insulation saved around 15 kilograms, while the use of components made from carbon-fibre-reinforced plastic (CFRP) deducted some eleven kilograms. For example, in addition to its CFRP roof, the bonnet and boot lid of the BMW M4 CSL are also hewn from this lightweight high-tech material, as is its centre console. And a titanium rear silencer cuts more than four kilograms from the weight of the exhaust system. Detail modifications to areas such as the BMW kidney grille, rear lights, floor mats and automatic climate control shave off another four kilograms.
