After the recent presentation of the BMW M5 Competition, the Helix firm seems to be in full development of the M4 CSL. A version that would mark the comeback of these three letters. Moreover, the official presentation seems to be approaching.
It had been a while since BMW had a ‘Leichtbau Sport Coupé’ model in its lineup, with the last CSL coming out ten years before the BMW 3 Series Coupé was named the 4 Series. The 2004 M3 CSL was followed. at the end of 2015 by the M4 GTS which took a similar approach by losing weight and gaining power. In 2018, the Bavarians announced their intention to remove the “GTS” suffix and make way for the return of the “CSL” badge for the Lightweight Sport Cup.
It was not until 2021 that the CSL letters made their long-awaited return. According to a BMW insider familiar with the German company’s agenda, an M4 CSL will be presented as early as next year. A veteran of the Bimmer Post forum, the author says construction on the sportier version of the M4 is expected to begin in July 2022 for what will be a ” very limited production series “. It is not known how many units will be produced, but chances are that less than 1,000 copies will be sold. If the M4 CSL lives up to its badge, it would make more sense to use the pure rear-wheel drive version equipped with the manual gearbox as a technical basis.
Weight is the enemy of performance
The lightest new generation M4 weighs 1,674 kg, making it approximately 34 kg heavier than the previous generation M4 Competition with the DCT box. To put that number into perspective, the M3 E30 was around 500kg lighter when it was released in the 1980s. Of course, its modern counterpart makes up for the excess weight with around 2.5 times the horsepower while. by being much better equipped in terms of on-board technologies.
It is not known how many kilograms the M4 CSL will gain compared to the classic version, but it is worth remembering that the M3 CSL (E46) lost 110 kilograms compared to the classic M3. Heavy use of carbon fiber would help him lose some weight, while a few more horsepower would improve his performance. If this information is legitimate and production will indeed begin in 2022, it probably means that the presentation will take place within a few months. Business to follow.
