The new 2023 M4 CSL is considered to be the closest product to BMW’s competition-specific siblings. This is a bold claim, and one that instantly distinguishes this car from most special versions, whose unique features are often confined to fancy trimming and off-menu color codes.
To achieve that “competition, sport, lightweight” mantle, the engineers at BMW M GmbH took a chain saw in some material and a scalpel in others. Notable changes include the lack of a rear seat and the removal of the roof, hood and trunk lids in carbon fiber.
240 lbs lighter, 40 horsepower, but no manual gearbox

bucktooth spit Kidney grills, rear lights, floor mats and automatic climate control. In total, 240 pounds (109 kg) has been thrown over the standard car – roughly equal to what was achieved with the 2003 E46 M3 CSL.
Output is bumped by a healthier 40 hp (41 PS / 30 kW) compared to the M4 competition, which brings the total input from the inline-six twin-turbocharged engine to 543 hp (550 PS / 411 kW). Surprisingly, energy flows through the rear wheels – there’s no room for a heavy all-wheel-drive system. Unfortunately for purists, there is no manual alternative. You can work with their eight-speed Auto M-specific version.
However, the result is the fastest series-production BMW to go around Nürburgring’s Nordschleife circuit, scheduled at 7: 20.2, with a carb weight of 3,640 lbs (1,651 kg), and a power to weight ratio of 6.7 lbs / hp.
Although M badges may seem like ten paise, CSL Monica is traditionally more sacred. Yes, CS aka Club Sport models abound, but the ones that have been added are hard enough. In fact, these three characters have only previously appeared in two cars: the E9 3.0 CSL “Batmobile” and the E46 M3 CSL.
Weight loss will be followed by fatigue and constant tiredness. In addition to getting rid of the rear seats, the front chairs have been replaced with M carbon flower buckets. It saves 53 pounds (24 kg). Carbon-ceramic brakes, forged wheels, and light springs and struts cut a further 46 pounds (21 kg). Pairing again on the sound insulation and switching to what is available for an “ultra-lightweight” solution saves 33 pounds (15 kg).

If you are not affected by this point, switching to Titanium Exhaust will not save 9 pounds (4 kg). However, we predict further boasting of owners already highlighting the widespread use of carbon fiber. In fact, while carbon fiber roofs have become more common since M3 CSL was introduced (now optional in 2022 M3 and M4), M4 extends the application of CSL material to the hood and trunk lid.
Although BMW has completely avoided “Fast and Furious”, leaving the entire hood open, they have left two channels highlighted by the red accent to inform the world of CSL’s Lightweight Certificate. These red lines extend to the roof, emphasizing the double bubbles.
CSL is the most powerful road-going variant of the M4, where 543 hp (550 PS / 411 kW) is produced at 6,250 rpm and 479 lb-ft (649 Nm) of torque is available from 2,750–5,950 rpm. This is enough for 3.6 seconds for a time of 0-60 mph (0-96 km / h) – 0.2 seconds faster than the M4 competition (but 0.2 seconds slower than the M4 competition xDrive) – and at a top speed of 191 mph (307 km / h) ).
The output increase from the 3.0-liter twin-turbo Straight-Six is partly due to a change in the boost system. In addition to further weight-saving advances in the engine, the boost pressure has been increased, from 24.7 psi in the M4 competition to 30.5 psi in the CSL.

BMW highlights the revitalizing-happy nature of the engine and says that components such as the uniquely designed engine and transmission mount improve road power transmission and enhance driver connectivity.
Although the lack of a third paddle will bother seekers of their purest driving experience (and that driver’s preoccupation with BMW as mentioned earlier), the eight-speed transmission is reportedly tuned to communicate with the driver as much as possible. Includes a track-optimized setting.
The M4 CSL features unique damper and chassis tuning, its ride height is 0.3-inches lower than the M4 competition. The suspension is further enhanced with a rigid connection between the zero-play ball joint, body and rear subframe in the control arms and specially engineered anti-roll bar.
The traction control program has also been tweaked for CSL, designed for controlled drift with one set of options, and another set based on the Turing Car application. Subsequent modes allow for the fastest track time, with settings prepared for specific situations – for example, there is a TC setting for running dry weather with perfect tire temp. This is the lowest level of intervention. On the other hand there are settings for running wet weather, which will make the computer more willing to intervene gradually.
The power is controlled by a set of six-pistons, a fixed-caliper brake at the front and a single-piston, floating-caliper at the rear. The paddle feel can be adjusted via the M setup menu by adjusting the required brake pressure.
Michelin Pilot Sport is specially designed to connect M4 CSL with Terra Pharma
Cup 2R tires measuring 275/35 ZR19 on the front and 285/30 ZR20 on the rear. If these two are extreme (read, if you want something more suitable for everyday driving) then CSL can be ordered from the M4 competition with traditional high-performance tires, at no cost.
There is no curved screen inside
Unlike the new M3 internal update, the M4 CSL won’t get the latest curved screen from BMW. Instead, the interior highlights are the M-Carbon full bucket seat and a Carbon Fiber Center console, both exclusive to CSL.
It’s impressive for a track-inspired car, the seats mentioned above may not be appreciated by your significant other. They have no backrest angle adjustment, and height can only be adjusted in a workshop. Headrests are easy to remove though – when you’re wearing a helmet. Hardcore.

BMW clearly realized that the lack of compatibility may not be to everyone’s liking, so the heated M carbon bucket seat option with full power compatibility is available as a no-cost option. While they don’t offer the 53-pound weight savings of full carbon buckets, they are still 21 pounds lighter than what you would expect in an M4 competition.
Not for compressed violet
The M4 CSL is available in three colors: Brooklyn Gray Metallic, Standard Alpine White or Black Sapphire Metallic. In celebration of M GmbH’s 50th anniversary, it features BMW’s Motorsport Roundle, while the badge is outlined in black, red accents.
The front end is just as impressive as you’d expect, with fewer ingredients in the name of the new grille – yes, you guessed it – saving weight. The Snoot has more red accent features, while the daytime running lights are illuminated in yellow, mimicking a GT racing car, much like the M5 CS.
At the rear is a new LED rear light with a “BMW laser”: Technology is unveiling at CSL. The back is equipped with a docktail spoiler, returning to the E46 M3 CSL.
Limited to 1,000, starting at $ 139,900
With production starting in July 2022, if you want one of these, you may want to keep your order sharp – M4 CSL will be limited to only 1,000 units worldwide.
Prices start at $ 139,900 and charge a $ 995 destination. This is a significant bump above the MSRP starting at $ 74,900 for the rear-wheel drive M4 competition coupe. In fact, it puts the M4 CSL in Porsche 911 Carrera GTS territory.
Although M4 CSL is definitely a different overall package from many others out there, would you dip your money into one if given the chance? Let us know below.
