See how the M4 CSL sets the Nurburgring lap record for production BMWs

Shortly after introducing the M4 GTS in 2015, BMW announced that the extreme coupe with its water injection system had lapped the Nürburgring in 7 minutes 27.88 seconds. Fast-forward to 2022, its spiritual successor has managed to shave off more than seven seconds by completing a lap of the Nordschleife in 7 minutes 20.20 seconds. Consequently, the M4 CSL is now the fastest street-legal BMW in the Green Hell.

Behind the wheel of Bavaria’s third Coupe Sport Lightweight model was development engineer Jörg Weidinger. Working for BMW for more than 20 years and at M GmbH since 2013, the skillful driver was also responsible for the M4 GTS’s lap time. The reason the car is still camouflaged is that the record race was run while the M4 CSL was still being tested at the ‘Ring.

Pause the video at exactly the 7:05 mark and you can see the prototype reaching a magical 300 km/h (186 mph) down the long straight. Jörg Weidinger pushed the M4 CSL to near maximum as the car tops out at 191 mph (307 km/h) after doing 0-62 mph (100 km/h) in 3.7 seconds and 0-124 mph ( 200 km/h) in 10.7 seconds.

These impressive numbers were made possible after increasing the output of the inline six-cylinder engine by 40 horsepower and shedding 240 pounds (108.8 kilograms) compared to the Competition model. The automatic-only CSL also received aerodynamic upgrades, allowing it to tackle corners at higher speeds than lesser flavors of the M4. For superior stopping power, ceramic brakes come as standard equipment, and the same can be said for electronically controlled adaptive suspension dampers.

Although the next XM will be a dedicated M car and the first since the original mid-engined M1, its lap time is highly unlikely to come close to the M4 CSL’s lap time. It’s impossible to design a heavy SUV to be as nimble as a much smaller vehicle that only has two seats. That said, BMW is believed to be planning a revival of the 3.0 CSL based on the M4 CSL, but with 600 horsepower and even a manual gearbox.
