New BMW M4 CSL: a tribute to the historic sports models of the German brand

As part of its 50th anniversary celebrations, BMW M GmbH is presenting a special edition vehicle based on its successful high-performance models in the premium midsize segment. The new BMW M4 CSL combines old-school racing passion with innovative technology to create an experience like no other.

With its next-level power and intelligent lightweight design, two-seater configuration, model-specific chassis upgrades and equipment features selected especially for the job at hand, the new BMW M4 CSL has track driving as its raison d’être. The genes the M4 CSL shares with its racing-spec sibling, the BMW M4 GT3, are also reflected in its performance attributes.

In test runs on the Nürburgring Nordschleife circuit, the BMW M4 CSL recorded the fastest lap times to date for a series-produced BMW car. On the version of the track that is traditionally used for comparison, which is 20,600 kilometers long and does not include the T13 straight, he stopped the clock in 7 minutes 15.677 seconds. His official and notarized lap time for the 20.832 kilometer circuit (the full lap) was 7 minutes 20.207 seconds. Acceleration figures of 3.7 seconds from 0 to 100 km/h and 10.7 seconds for acceleration from 0 to 200 km/h are equally impressive.

“Competition, Sport, Lightweight”: a recipe with a rich tradition

The stripped-down racing character of the BMW M4 CSL is underpinned by a time-honored concept that harnesses cutting-edge development expertise and the latest technology to create a fascinating end result. “CSL” stands for “Competition, Sport, Lightweight”, referring to the critical role of minimal weight design in achieving motorsport success. The BMW 3.0 CSL developed by BMW Motorsport GmbH according to this same principle won the European Touring Car Championship at its first attempt in 1973. And the BMW M4 CSL also follows in the footsteps of the successful special edition models of previous generations of the BMW M3. and the BMW M4, most notably the legendary BMW M3 CSL from 2003 and the BMW M4 GTS introduced in 2016.

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

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

His flair for innovation and knowledge of racing cars enabled BMW M GmbH to restrict the DIN curb weight of the special edition to 1,625 kilograms. An outstanding power-to-weight ratio of 2.95 kilograms per hp provides the ideal platform for a dynamically sublime driving experience.

The installation of the M Carbon bucket seats reduced weight by around 24 kilograms on its own, compared to the standard seats fitted to the BMW M4 Competition Coupé. 21 kilograms were saved by removing the rear seats and seat belts, integrating a partition and making corresponding modifications to the trunk. And changes to the chassis, including the addition of extra-lightweight M Carbon carbon-ceramic brakes and special light-alloy wheels, springs and shock absorbers, cut the figure by around another 21 kilograms. Reducing the amount of soundproofing plus switching to ultra-light sound insulation saved about 15 kilograms, while using components made from carbon fiber reinforced polymer (CFRP) saved about eleven kilograms.

For example, in addition to its CFRP roof, the bonnet and boot lid of the BMW M4 CSL are also made of this lightweight, high-tech material, as is its center console. And a titanium rear silencer shaves more than four kilograms off the weight of the exhaust system. Detailed modifications in areas like BMW’s kidney grille, taillights, floor mats and automatic climate control shed another four kilograms.


The BMW Live Cockpit Professional, also standard, comprises a fully digital display cluster consisting of an instrument cluster with a 12.3-inch screen diagonal behind the steering wheel and a 10.25-inch control display. Among its functions are the navigation system, the BMW Intelligent Personal Assistant, smartphone integration, telephony with wireless charging and Wi-Fi interface. The BMW Head-Up Display with M-specific elements can be ordered from the options list.

The range of comfort-enhancing features and driver assistance systems fitted to the BMW M4 CSL focus on the essentials, in keeping with its approach to intelligent lightweight design and its purist vehicle concept. The standard specification includes automatic climate control, parking distance control, forward collision warning, lane departure warning, and speed limit information. Dual-zone automatic climate control as well as the Driving Assistant and Parking Assistant systems are available as options.

BMW Laserlight: innovative yellow headlights and taillights

The optionally available BMW Laserlight headlights add another striking accent to the front end of the new BMW M4 CSL. In both the welcome effect activated by unlocking the doors and when the high and low beams are turned on, these headlights illuminate yellow instead of white, recalling the look of successful GT racing cars.

The LED taillights of the new BMW M4 CSL are equipped as standard with technology that makes its debut in a series-produced vehicle. Their glass covers have intricately interwoven threads of light that are illuminated using laser technology, bringing a vibrant structure to the surface of the lights. This creates a highly distinctive light signature that is recognizable from a long distance during hours of darkness.

Inline six-cylinder engine with racing-focused character

The model-specific power unit of the BMW M4 CSL is based on the same high-revving inline six-cylinder engine with M TwinPower Turbo technology found in the BMW M4 GT3 racing car. Its significant performance reserves allowed for a huge increase in power without having to make any compromises in terms of stability or durability. Key to this power increase was an increase in the maximum charge pressure of the two mono-scroll turbochargers from 1.7 bar to 2.1 bar and model-specific tweaks to engine management. The engine of the BMW M4 CSL develops a maximum torque of 650 Nm between 2,750 and 5,950 rpm. Its maximum power of 405 kW/550 hp is produced at 6,250 rpm.

The race-derived design of the 3.0-litre engine is squarely focused on high revs and maximum power development. The crankcase’s sleeveless, closed-deck construction helps make it extremely rigid, while the lightweight forged crankshaft allows it to handle extremely high levels of torque. Another special feature specific to M is the head core made using 3D printing techniques.

Both the cooling and oil supply systems are designed to handle the particular challenges that track driving presents. The electrically controlled finned twin tailpipe exhaust system and weight-reduced titanium rear silencer further generates an emotionally captivating, racing-inspired engine note, created especially for the new BMW M4 CSL.

The torque produced by the engine is transmitted to the rear wheels of the new BMW M4 CSL via an eight-speed M Steptronic transmission with Drivelogic. Model-specific engine and transmission mounts ensure that engine power is translated into dynamic performance exceptionally quickly and directly. The firmer connection of the engine and transmission to the vehicle structure is clearly noticeable, especially in demanding driving.

Track-optimized M Traction Control

The standard-equipped M traction control function with model-specific track tuning allows the driver to set individual intervention thresholds for wheel slip limitation. On dry surfaces, stages 1 to 5 of Traction Control M help the driver to perform controlled drifts. Stages 6 to 10 are based on the application developed for touring car drivers and take into account both surface conditions and tire temperature to maximize traction and directional stability.

Also included as standard are forged M light-alloy wheels in an exclusive cross-spoke design (19-inch at the front and 20-inch at the rear). They are equipped with high-performance tires specifically developed for the special edition model, in size 275/35 ZR19 at the front and 285/30 ZR20 at the rear.
