As part of its 50th anniversary, BMW M GmbH is announcing a special edition car based on a successful high-performance model in the premium mid-sized segment.

The new BMW M4 CSL combines old-fashioned racing passion with innovative technology to create an unparalleled performance experience, the car company said in a statement.

The new BMW M4 CSL features the next level of power and intelligent lightweight design, two-seater configuration, model-specific chassis upgrades, and equipment features specifically selected for the task at hand, and its raison d’etre is truck driving. Is equipped with. The genes that M4CSL shares with its competing sibling, BMW M4 GT3, are also reflected in its performance attributes. In a test run at the Nürburgring Nordschleife circuit, the BMW M4 CSL set the fastest lap time in history for a series of BMW cars. The version of the truck, traditionally used for comparison, with a length of 20.600 kilometers / 12.8 miles, did not include the straight in section T13 and the clock stopped in 7 minutes. 15.677 seconds The officially notarized lap time for the 20.832km / 12.943 mile circuit (complete lap) was 7 minutes. 20.207 seconds 3.7 seconds from 0 to 100 km / h (62 mph) and 10.7 seconds from the sprint from 0 to 200 km / h (124 mph) are equally impressive. Competition, sports, lightweight: recipes with a rich tradition. The stripped racing character of the BMW M4 CSL is underpinned by an old-fashioned concept that leverages cutting-edge development expertise and the latest technology to produce captivating end results. CSL stands for Competition, Sport, and Lightweight and represents an important role in designing to minimize weight for success in motorsport. Developed by BMW Motorsport GmbH according to this same principle, the BMW 3.0 CSL won the European Touring Car Championship in the first attempt in 1973. The M4 CSL also follows the successful special edition tire trucks of BMW’s early generation. The M3 / M4, especially the legendary BMW M3 CSL in 2003 and the BMW M4 GTS announced in 2016.

For BMW M GmbH, the world premiere of the new BMW M4 CSL at the Concorso Deleganza Villa d’Este (May 20, 2022, 22nd) will be one of the highlights of its 50th anniversary. Production of the special edition model will begin in July 2022 at BMW GroupPlant Dingolfing with a limited production of exactly 1,000 cases.

The intelligent and lightweight design of the BMW M4 CSL.

Due to its innovation and its talent for racing car know-how, BMW MGmbH was able to limit the weight of the special edition DIN curb to 1,625 kilograms. An outstanding power-to-weight ratio of 2.95 kilograms (4.01 kg / kW) per horsepower provides an ideal platform for a dynamically sublime driving experience.

Installing the M Carbon full bucket seat reduced the weight by itself by about 24kg compared to the standard seat installed in the BMW M4 Competition Coup. We saved 21 kilograms by removing the backseats and seat belts, consolidating the partitions, and making changes related to the luggage compartment. In addition, chassis changes such as the addition of ultra-lightweight M carbon ceramic brakes, special light alloy wheels, springs and struts have further reduced this number by approximately 21kg. Reducing the amount of soundproofing and switching to ultra-lightweight insulation saved about 15 kilograms, but with components made of carbon fiber reinforced plastic (CFRP), about 11 kilograms were deducted. For example, in addition to the CFRP roof, the BMW M4 CSL’s bonnet and boot lid are cut out of this lightweight high-tech material as well as the center console. The titanium rear silencer also reduces the weight of the exhaust system by more than 4 kilograms. Changes in area details such as the BMW Kidney Grille, rear lights, floor mats and automatic temperature control will save an additional 4 kilograms.

Unique exterior paint finish, model-specific design features.

The body of the BMW M4 CSL is painted in a special Frozen Brooklyn Gray Metallic as standard. This exterior shade, combined with the exposed carbon fiber surface and red accents, creates an appearance that visually represents the purity of the sport. Alternatively, the customer can specify the new M4 CSL with Alpine White Solid or Sapphire Black Metallic.

The carbon fiber structure of the body components can be seen in various areas, including the two deep indentations in the bonnet. The surface of the indent, which is not painted in body color, is further accentuated by the red outline. The red accent lines also focus on the two fins on the new BMW M4 CSL’s CFRP roof, side sill contours, black model badges, and model-specific CFRP splitter and air curtain inserts on the front apron.

BMW Laserlight: Yellow headlights and innovative rear lights.

Optional BMW Laserlight headlights bring another head-turning accent to the front end of the new BMW M4 CSL. Both with the welcome effect triggered when the door is unlocked and when the low and high beams are turned on, these headlights turn yellow instead of white, reminiscent of the look of a successful GT racing car. increase.

The LED rear lights of the new BMW M4 CSL are equipped as standard with the technology that debuts in series production vehicles. Their glass covers are woven with intricate threads of light and illuminated using laser technology to create a vibrant structure on the surface of the light. This creates a very distinctive light feature that can be recognized from a distance during dark hours.

A 6-cylinder in-line engine with a race-oriented character.

The model-specific power unit of the BMW M4 CSL is based on the same high-revving 6-cylinder in-line engine and MTwin Power Turbo technology found in BMW M4 GT3 racing cars. Its substantial performance reserve allowed it to significantly improve power without compromising on stability and durability. The key to this power boost was to increase the maximum charge pressure of the two monoscroll turbochargers from 1.7 bar to 2.1 bar and adjust engine management model-specific. The BMW M4 CSL engine produces a peak torque of 650 Nm (479 lb-ft) at 2,750-5,950 rpm. The maximum output of 405kW / 550hp is produced at 6,250rpm.

The race-derived design of the 3.0-liter engine focuses head-on on the development of high revs and maximum power. Due to the sleeve-free closed deck construction of the crankcase, it is extremely rigid and the forged lightweight crankshaft can handle very high levels of torque. Another special M-specific feature is the cylinder head core created using 3D printing technology.

Both cooling and oil supply systems are designed to handle the specific challenges presented by trucking. Featuring electrically controlled flaps and a titanium rear silencer with minimal weight, the Twintail Pipe Exhaust System adds a touching engine note inspired by racing cars specially created for the new BMW M4 CSL. Generate.

The drive torque generated by the engine is transmitted to the rear wheels of the new BMW M4 CSL via an 8-speed M-steptronic transmission with Drivelogic. Model-specific installation of the engine and transmission translates engine output into dynamic performance in a very quick and direct way. The stronger connection of the engine and transmission to the car structure is clearly recognizable, especially under hard drive.

Optimized body rigidity, model-specific chassis technology.

Like the new BMW M4 CSL engine, its chassis technology benefits from a wealth of detail upgrades tailored to the performance characteristics of the power unit. These changes also take into account the significant reduction in vehicle weight here and the increased model-specific body stiffness, and the agility of handling that is famous for raising BMW M cars to new heights. Allows a blend of dynamism and precision.

In the engine room, the front-end strut bar has been developed from scratch to further improve the body rigidity of the new BMW M4 CSL. Using a numerical model, the shape of the cast aluminum element between the spring strut tower and the front end is precisely adapted to the forces applied in different driving situations.

Individually tuned axle kinematics and model-specific wheel camber settings, dampers, auxiliary springs, anti-roll bars for steering accuracy, lateral control when cornering, spring and damping response, and wheel Optimize the position. The model-specific wheel suspension is accompanied by an 8mm drop in ride height compared to the BMW M4 Competition Coup. The standard equipment list for the special edition model also includes the Adaptive M Suspension with electronically controlled dampers, the electromechanical M Servotronic steering with variable ratios, and the M carbon ceramic brakes. The M-only version of the integrated braking system provides the driver with an excellent pedal feel, even when pushing dynamic limits or on rough roads.

M traction control optimized for trucks.

The standard M-Traction Control feature with model-specific track tuning allows the driver to set individual intervention thresholds for wheel slip limits. On dry roads, stages 1-5 of M Traction Control help the driver perform a controlled drift. Stages 6-10 are based on applications developed for touring car racers, maximizing traction and directional stability, taking into account both surface conditions and tire temperature.

Forged M light alloy wheels with a dedicated cross-spoke design (19 inches on the front axle and 20 inches on the rear) are also standard equipment. Equipped with high performance tires specially developed for special edition models of size 275/35 ZR19 (front) and 285/30 ZR20 (rear).

Equipment designed to provide a race car feel and everyday ease of use.

With model-specific equipment features, the BMW M4 CSL offers a unique balance between sports car purity, unlimited everyday usability, and exclusive premium material. The M carbon full bucket seats for drivers and co-drivers are characterized by a self-supporting CFRP construction and deliberate elimination of comfort-enhancing features. The angle of the backrest is fixed, the front and back adjustments can be made manually, and the seat height can only be adjusted in the workshop using a three-step screw linkage. The M carbon full bucket seat also has a removable headrest for integration with a 6-point belt system.

The M Alcantara steering wheel, anthracite headliner, carbon fiber interior trim strips, seat CSL badges, center console, rear panel, and M-specific display also create the perfect onboard setting for focused driving pleasure. Useful for. Enhanced merino leather trim and M seat belts are also standard equipment. There are two helmet storage units in the rear compartment.

The M-specific control / operation system includes an M setup button for direct access to numerous vehicle settings and two M buttons on the steering wheel for storing priority configurations. Standard equipment includes M Drive Professional systems such as the MDrift Analyzer and M Laptimer, as well as M-mode buttons for activating ROAD, SPORT and TRACK settings.

Similarly, the standard BMW LiveCockpit Professional consists of a complete digital screen group consisting of an instrument cluster with a 12.3-inch screen diagonally behind the steering wheel and a 10.25-inch control display. Among its features are the navigation system BMW Maps, BMW Intelligent Personal Assistant, smartphone integration, phones with wireless charging and Wi-Fi interface. BMW heads-up displays and BMW drive recorders with M-specific elements can be ordered from the options list.
