There’s “more to come” with the much-rumoured BMW M2 CSL, according to BMW Australia chief Marc Werner.

Speaking at the launch of the BMW M3 and M4 Competition models – each with a 14kW power boost to 331kW – the local managing director gave the strongest hint yet that the M2 CSL is coming soon.

The CSL – or “coupe sport lightweight” – version is expected to mimic the limited edition BMW M3 CSL released in 2004 in having motorsport-inspired lightweight panels and materials as well as engine modifications to up performance.

The M2 CSL appears to be a key part of a broader plan to expand the BMW M family, and take advantage of strong demand for low volume, highly modified machines.

Based on the M4 Coupe, the two-seater GTS has heavy aerodynamic modifications as part of major body and structural changes that also realise a 30kg weight saving.

The claimed 0-100km/h time is 3.8 seconds – just 0.2 seconds quicker than the M4 Competition – but the Nurburgring lap time is a more convincing 7 minutes, 28 seconds.

“It’s a full blooded race track car,” said BMW Australia product and pricing manager for the M3 and M4, Howard Lam. “It’s a track car been made road legal, not the other way around.”
