BMW’s M division celebrates its fiftieth anniversary in style with the radical M4 CSL, the fastest sports car ever in the German brand’s history.
Limited to 1,000 cars, it’s lighter and more powerful than the BMW M4 Competition, and the ground links are more efficient and powerful.
The bottom line, however, is that the Demon version is almost in and of itself but its evolution is quite different in making it a completely new car.
The official presentation is taking place this weekend at the Villa d’Este elegance competition in Italy.
Fastest in the Nürburgring
As the acronym CLS (Competition Sport Lightweight) indicates, this variant weighs 100 kilograms less than the 1,800 kilogram model it descends, thanks to the abuse of carbon fiber in its construction.
What you lose in weight gain is in power: 40 hp more, which goes up to 550 hp at 6250 rpm.
This increase, achieved with increasing turbine pressure from 1.7 to 2.1 bar, results in a 2.95 kg/hp ratio between weight and power.
The maximum torque remains at 650 Nm but in a wider rev range, between 2,750 and 5950 rpm.
Power is transmitted to the rear wheels only through an automatic transmission. Steptronic Eight-speed with torque converter.
Shift times have been shortened to the same speed as the dual-clutch transmission.
On the track, he already showed how fast he could go, as BMW drove him into the “green hell” at the Nürburgring in 7:15.677 minutes on the short version of the 20.6km circuit.
In the longest configuration, with 20,832 kilometers, the achieved time was 7: 20.207 minutes, which means it is the fastest German Badge model on this track ever.
If there is still any doubt, it should be noted that 0 to 100 km/h is achieved in 3.7 seconds (a tenth less than the M4 competition) for a top speed of 307 km/h.
Of course, for these performances it was necessary to increase the rigidity of the chassis, the mounts for the engine and gearbox are more stable.
The suspension, supported by electronically controlled dampers, has new modifications that lower the body’s ground clearance by up to 8 mm compared to the M4 competition.
The camber of the front wheels has also been increased and stability is ensured by larger diameter bars.
On dry roads, levels 1 through 5 of M traction control allow you to perform a tight glide, while levels 6 through 10 depend on the system developed for road drivers.
It’s adjustable according to wet or dry conditions, as well as tire temperature, for increased traction and directional stability.
Radical weight loss
In the genesis of the BMW M4 CLS’s weight reduction was the semi-“uncontrolled” use of carbon fiber in the chassis.

You can also choose metallic tones. white alps or black sapphirewith the brand symbol in black to mark the 50th anniversary of the M division, with red and blue details outlining the lettering.
The ultra-thin carbon seats, which must be adjusted to order at the dealership, save 24 kg.
Removing the rear seat, replacing it with a hollow cover for storing two helmets, removing another 21 kilograms, adding another 15 kilograms by removing the soundproofing material.
The titanium exhaust muffler delivered 4.3 kg, and the single-zone air conditioner and basic standard audio system offered on the M4 package allowed another 11 kg to be shed.
Specific dampers, 19- and 20-inch light-alloy wheels, and carbon-ceramic brakes dampen another 21 kg.
The huge radiator grille, which reveals the mechanics in all its splendor, also contributes to this slimming remedy.
Bordered by red, the same color can be found on the edges of the cap, roof and spoiler Front and side skirts, with LED taillights including laser lighting as an option for the first time.
As with the M8 Gran Coupé First Edition, BMW proposes yellow daytime running lights that evoke the world of competition.
The interior is distinguished by two screens with the system BMW Live Cockpit Professionalwith 12.3-inch hardware and 10.25-inch infotainment.

With two buttons on the steering wheel, it is possible to memorize two system settings that affect the dynamics of the M4 CLS.
The seats slide manually along the rails, but to adjust the height, this must be done in the dealer’s workshop.
The seat backs are at a fixed angle, the headrests are removable when a helmet is worn, and there are six attachment points in the seat belt holders.
In the area of active safety and driving support, it has parking assist sensors, forward collision alert and unintended lane departure detection as standard, as well as a wireless charger for mobile phones.
Since the production is limited to 1000 copies, few copies will reach our country. In Germany prices start from 165,200 euros.
