The BMW M2 CS has been flaunting its boosted credentials since its reveal, and now, engineers in Munich are hinting at stopwatch heroics to back up the numbers. In development testing at the Nürburgring Nordschleife, the coupé is said to be within touching distance of the M4 CS benchmark, putting clear asphalt between itself and every direct rival. BMW M’s Dirk Häcker reports that the time logged is “much closer to the M4 than the standard M2,” pointing to a lap well under seven minutes thirty seconds—an eye-opening gain on the 7:38.7 recorded by the regular car.

Such pace comes courtesy of a twin-turbo three-litre straight-six now breathing out 523 bhp and 479 lb ft, delivered solely to the rear tyres through the familiar eight-speed automatic. Lightweight body panels, track-honed suspension and model-specific Michelins ensure every kilowatt is put to work when the circuit tightens. Häcker also notes that the M2 CS edges ahead of “the next manufacturer”, suggesting it undercuts times posted by Alfa’s Giulia GTAm, Porsche’s Cayman GT4 RS and Mercedes-AMG’s A45 S on the same tarmac.

Rumour mills in Bavaria are already spinning about what comes next. An xDrive derivative of the core M2 could appear in 2026, promising all-weather traction but likely conceding a few tenths to the rear-drive CS. Further down the line, enthusiasts whisper about a stripped-back M2 CSL arriving towards the end of the model cycle with even less mass and an extra squeeze of boost, potentially the swansong for petrol-powered compact M cars before electrification takes the stage.
For now, all eyes remain on the official Nürburgring time. When BMW finally pins the figure to the timing boards, the M2 CS looks set to cement its status as the sharpest small coupé in the line-up, proving that a well-sorted chassis, a proper straight-six and the Nordschleife’s unforgiving concrete still make the perfect proving ground.
