BMW's Mighty M4-Engined 'M2 CS' Has Been Spotted At The 'Ring

The rumoured M2 Club Sport is moving ever closer to reality, if this video is anything to go by.

Combining the M2 body with the engine and suspension from the M4 sounds like a mighty combo, and this footage from the Nurburgring claims to show a test mule for exactly that.

Camouflage around the sides and bumpers of this prototype ‘M2 CS’ could be hiding extra intake ducts, wider arches or added cooling vents.

So far the suggestion is that the M2’s N55 six-pot would be swapped for the S55 from the larger car – a move that hasn’t thrilled everyone – but with a new state of tune dropping output to around 400bhp.

The N55 is said to be close to its limits in terms of performance without major upgrades, hence the wholesale change of block. There’s a lot of crossover in the rumour mill between an M2 CS and a lightweight M2 CSL, but both could ultimately be spawned from this project.

Whichever version arrives first is expected to plug the sizeable cost gap between the M2 and M4. BMW Australia managing director Marc-Heinrich Werner was quoted earlier in the year as saying the upgraded M2 “looks fantastic”, before adding: “there is more to come.”
