BMW will reportedly revive the CSL badge for use on the G82-generation M4, with the hardcore variant set to debut in 2022 in very limited numbers.

According to BMWBlog, the “insider” who revealed the information over on Bimmerpost has proven to be “quite accurate” in the past.

So, what do we know? Well, the latest rumour suggests the new M4 CSL will start rolling off the assembly line by July 2022, with its production run scheduled to be “very short”. That, of course, points to a very limited supply.

Little else is known about the rumoured M4 CSL, though if the hardcore variant does indeed materialise we can expect the same sort of kit we saw on the F82-generation M4 GTS and M4 DTM Champion Edition.

That means there would likely be items such as a towering rear wing, a more prominent front lip, track-focused suspension, bespoke wheels, various weight-saving measures and perhaps even a roll cage in place of the rear seats.

As BMWBlog points out, it remains to be seen which transmission the Munich-based firm would opt for (the eight-speed automatic or six-speed manual) in such a variant, as well as what sort of tune it’d apply to the turbocharged 3,0-litre straight-six engine...
