In test runs on the Nürburgring’s Nordschleife circuit, which represent the ultimate yardstick for brand-typical dynamics, agility and handling precision for all BMW M cars, the BMW M4 CSL posted a lap time of 7 min. 15.677 sec. on the version of the track traditionally used for comparison purposes – which is 20.600 kilometres / 12.8 miles in length (it doesn’t include the straight at section T13). The official and notarised lap time for the 20.832-kilometres / 12.9 miles circuit (the complete lap) was 7 min. 20.207 sec., the best figures ever for a series-produced BMW car. The BMW M4 CSL set a new official record in the middle class segment.
