With its next-level power and intelligent lightweight design, two-seater configuration, model-specific chassis upgrades and equipment features selected specially 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 competition-spec sibling, the BMW M4 GT3, are also reflected in its performance attributes. In test runs on the Nürburgring's Nordschleife circuit, the BMW M4 CSL posted the fastest lap times ever for a series-produced BMW car.
"Competition, Sport, Lightweight"
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 2022 Concorso d'Eleganza Villa d'Este 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.
The body of the BMW M4 CSL is painted in the exclusive Frozen Brooklyn Grey metallic as standard. This exterior shade teams up with exposed carbon-fibre surfaces and red accents to create a visually expressive appearance of sporting purity. Alternatively, customers can specify their new M4 CSL in Alpine White solid or Sapphire Black metallic.
The carbon-fibre structure of the body components is visible in various areas, including the two chiselled indents in the bonnet. The surfaces of the indents - which are not painted in body colour - are highlighted additionally by red outlines. Red accent lines also bring extra emphasis to the two fins on the CFRP roof of the new BMW M4 CSL, the contours of its side sills, the black model badges, and the model-specific CFRP splitters and air curtain inserts in the front apron.
The model-specific power unit of the BMW M4 CSL is based on the same high-revving, six-cylinder in-line engine with M TwinPower Turbo technology found in the BMW M4 GT3 racing car. Its substantial performance reserves enabled a major hike in power without having to make any concessions in terms of stability or durability. Key to this power boost 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 the engine management. The BMW M4 CSL's engine develops peak torque of 650 Nm (479 lb-ft) between 2,750 and 5,950 rpm. Its maximum output of 550 hp is produced at 6,250 rpm.
The race-derived design of the 3.0-litre engine is focused squarely on high revs and maximum power development. The crankcase's sleeve-free, closed-deck construction helps to make it extremely rigid, while the forged lightweight crankshaft allows it to handle extremely high levels of torque. Another special M-specific feature is the cylinder head core made using 3D printing techniques.
Model-specific equipment features give the BMW M4 CSL a distinctive balance between sports car purism, unrestricted everyday usability and exclusive premium substance.
The M Carbon full bucket seats for the driver and co-driver are marked out by their self-supporting CFRP structure and purposeful rejection of comfort-enhancing features. They have a fixed backrest angle, forward/back adjustments can be made manually, and the seat height can only be adjusted in a workshop using a three-stage screw linkage. The M Carbon full bucket seats also have detachable head restraints and allow the integration of a six-point belt system.
The M Alcantara steering wheel, anthracite-coloured headliner, Carbon Fibre interior trim strips, "CSL" badges on the seats, centre console and rear panel, plus M-specific displays also help to create the perfect on-board setting for concentrated driving pleasure. Merino leather trim with extended features and M seat belts are also standard. Two helmet storage units can be found in the rear compartment.
The range of comfort-enhancing features and driver assistance systems fitted in the BMW M4 CSL are focused on the essentials, in keeping with its intelligent lightweight design approach and puristic vehicle concept. Standard specification includes automatic climate control, Park Distance Control, Front Collision Warning, Lane Departure Warning and Speed Limit Info. Two-zone automatic climate control, an alarm, and the Driving Assistant and Parking Assistant systems are available as options.
