The latest image teaser, released earlier this month, BMW after nearly 12 months of speculative reports has officially announced the M4 CSL as the hardest M4 ever.
The revival of the iconic “Coupe Sport Leichtbau” or Coupe Sport Lightweight, last used on the E46 M3 CSL, the arrival of the M4 CSL also pays tribute to the 50th Division M.th anniversary this year, a total of 1,000 items.
Like its predecessor, and the original 3.0 CSL “Batmobile” of the 1970s, the M4 CSL, according to its designation, has been experienced with a number of features to save weight.
This includes rear seats to save 21kg, replacing the front seats with M Carbon seats to shave off another 24kg, and abandoning most of the sound-absorbing materials for ultra-lightweight replacement made of carbon fiber reinforced plastic (CFRP) as a way to reduce weight by 15kg .
In addition, the equipment of the titanium exhaust system reduces the weight by another four kilograms, standard carbon ceramic brakes M – by 14 kg, and the roof and trunk lid – by 1.3 kg and 6.8 kg, respectively.
To this can be added a combined reduction of eight kilograms by installing lighter mats, restyling taillights and radiator grilles using materials to save weight, revise the climate control system and make a carbon fiber center console.
Overall weight savings compared to the M4 Competition is 108.8 kg, and the M4 CSL – 1625 kg.
In addition to the new lightness, additional exterior changes include a CFRP front splitter, double black racetracks with red outlines on the hood and roof, red accents on the grille, glossy black sills, also with red outlines, and black M4 CSL badges.

Mounted on model-specific glossy black forged alloy wheels M with 19-inch cross spokes and 20-inch rear spokes. Three colors are offered; standard Frozen Brooklyn Gray Metallic or optional Alpine White and Sapphire Black Metallic.
Not surprisingly, BMW has also tuned the M4 CSL chassis so that it is now eight millimeters closer to the ground than the Competition.
Also included are new support struts, revised suspension geometry, new engine mounts, stabilizers and springs, a different collapse from the competition, an electromechanical power steering and an adaptive M suspension with electronic shock absorbers.
The aforementioned carbon-ceramic stoppers meanwhile consist of a six-piston caliper at the front and a single at the rear, made of a light alloy surrounded by Michelin Pilot Sport Cup 2R rubber.
Without a carbon center console and removal of the rear seats, the placement of which now provides storage of a pair of helmets under the retaining net, the M4 CSL retains the Live Cockpit Professional setting, which consists of a 12.3-inch digital dashboard and 10.25-inch iDrive infotainment system.
Both, however, have a specific M reading and graphics with the same application to the M Heads-Up Display. The bucket seats, meanwhile, are trimmed with Merino leather and Alcantara and come with headrests with CSL backlighting as well as additional electric adjustment.
Alcantara on the steering wheel M completes the interior with anthracite roofing, M seat belts, CSL logo on the center console and rear panel, branded door sill lights and a fire extinguisher under the passenger seat.
The front-mounted 3.0-liter S58 twin-turbocharged S58 with a number of six-row engines benefits not only from a titanium exhaust system but also from a lightweight crankcase without sleeves to become the most powerful M4 ever produced.
With a power of 405 kW / 650 Nm, which is 30 kW more than in the M4 Competition, while torque remains unchanged, M4 CSL accelerates from 0-100 km / h in 3.7 seconds, 0.2 seconds faster than in the Competition, 0-200 km / h in 10.7 seconds and reach a limited top speed of 307 km / h.
In an unexpected step, but more than likely as a means of weight loss, CSL sends its number of turns to the rear axle only through a revised version of the eight-speed Steptronic transmission.
The M4 CSL’s public debut has been confirmed for South Africa, and only 15 units will be available from July on the shores of Lake Como in Italy. Expect possible prices of 2.5-3 million rupees.
