BMW may have christened the superlative of its M4 ‘CSL’, but in reality it is taking over from the previous generation GTS version. He took on the role of fastest M4 in the range in 2015, and he proved it with a brand record at the Nürburgring: he took just 7 minutes, 27 seconds and 88 hundredths. This made the M4 GTS faster than any other production BMW, but not anymore.
More than 7 seconds off
For the unveiling of the new M4 CSL, BMW is of course back along the Green Hell passed, and there the newcomer did exactly what he had to do: outdo his predecessor. In the capable hands of test driver and BMW engineer Joerg Weidinger, the then camouflaged sportsman raced over the ‘Ring in 7 minutes, 20 seconds and 20 hundredths, another 7 seconds faster than the M4 GTS did in 2015. the driver cannot have been the cause, because exactly the same pilot was at the helm at the time. You’ll also notice that it’s testing the limits of the CSL as it comes pretty close to its top speed of 307 km/h at minute 7:05.
With this, Weidinger crowns this M4 CSL, which is limited to 1000 pieces, as the fastest street-legal BMW ever, although the car still has a long way to go before it can set a real lap record on the Nürburgring. That has been in the name of the Porsche 911 GT2 RS for a year, which during its last outing with 6:38:835 shaved ten seconds off its previous record and is therefore more than 40 seconds faster than this BMW.
