In this 50th birthday year, BMW carThe M division is unveiling a bunch of new models to celebrate, and the latest on the long list is the new BMW M4 CSL.
Securing its status as the most active product of the M division is a tuned engine that pumps out more power, as well as some heavy chassis tweaks and a stylish body kit. .
The focus of CSL is weight reduction. The L in the CSL’s name stands for Lightweight, and this new model features many weight-saving measures.
The car weighs in at 1,625kg, 100kg lighter than the regular M4, with the heavy use of carbon fiber for the body panels saving 21kg. Highlights of the current M Division carbon fiber roof, combined with the carbon fiber bonnet (1.2kg lighter and accented by exposed areas) and trunk (economy) 6.7kg) to give the CSL a more aggressive look.
This is aided by a deeper front bumper with a new kidney grille layout with only one crossbar, as well as enlarged sub-grids for improved cooling, plus splitter details. The lower carbon fiber is emblazoned with CSL lettering.
Light-weight M carbon-ceramic brakes come standard, which saves 14.3kg over standard steel items, unique alloy wheels – 19 inches at the front and 20 inches at the rear – and various suspension springs and struts are also part of the CSL package, and an overall 21kg savings. To further improve handling, the CSL features an aluminum brace under the bonnet, improving structural rigidity.
The M4’s standard 3.0-litre twin-turbo six has been developed to produce 542hp – 39hp more than the M4 Competition – while torque remains the same at 650Nm. Additional power comes from increased turbocharger pressure, up from 1.7 to 2.1 bar, along with a redesigned ECU, while the exhaust system now features a titanium silencer, which saves money. 4.3 kg. The engine is also attached to the chassis using stiffer engine mounts to create a feel “reminiscent of a race car”, according to BMW.
There is no manual transmission option, only BMW’s eight-speed automatic transmission. Unlike the standard M4 Competition, the company’s M xDrive setup isn’t offered either, so the CSL is rear-wheel drive only, but with launch control and sticky tires, it sprints from 0- 62mph in 3.7 seconds. Top speed is 190mph.
Inside, the interior has a carbon fiber center console, which saves about 4kg. BMW has also equipped a pair of M carbon bucket seats, which saves 24kg, while the company has completely removed the rear seats of the car, helping to save an additional 21kg. The switch to ultra-light soundproofing helped save an additional 15kg.
Unlike the optional two-piece bucket seat on the M4 Competition (available as an option), the CSL’s one-piece seat is much more focused; they feature cutouts for six-point belts, reinforcing the car’s focus on track use.
With this in mind, M4 CSL has established a Nurburgring lap time is 7: 15.667, making it the fastest BMW ever on the famous track.
Other unique touches to the interior of the CSL include the Alcantara steering wheel and carbon fiber gearshift paddles, as well as the liberal use of Alcantara trim pieces elsewhere inside the cabin.
Adaptive dampers, variable steering and BMW’s integrated M brakes are all standard, with the suspension having a reduced travel height of 8mm compared to the M4 Competition, helping to lower the center of gravity of the vehicle. car.
The shock absorbers have auxiliary springs at both front and rear, while the rear suspension’s rubber bushings have been replaced with ball joints for improved precision. The front end also has more negative camber due to the CSL’s intended use on the track.
The suspension settings can be adjusted electronically with three modes available: Comfort, Sport and Sport Plus. BMW has implemented its adjustable M Traction Control setup, which can engage the M Dynamic Mode; The first year is the same as in the standard M4, with the second year of the 10-stage system optimized for traction in track conditions.
The Road and Sport driving modes are therefore combined with a new Track setting for the CSL, skin switching on the 12.3-inch digital instrument cluster and optional head-up display if indicated. determined. The digital instrument panel is paired with a 10.25-inch central display, which features the same infotainment system as the regular M4, including the M-specific Drive Professional system with lap timer. and deviation analyzer.
Other standard equipment includes BMW’s Laserlight headlights, which illuminate in yellow rather than white to evoke the spirit of GT racing cars, while the taillights for the CSL also have a new projection design. laser light.
Only 1,000 M4 CSLs will be produced, of which only 100 will be allocated to the UK. The car is currently for sale from £128,820.
