Rumors about a new model from BMW's M division used to evoke nothing but unbridled anticipation, but these days, we're a bit more circumspect about the prospect. After all, we've all seen what the new XM SUV looks like, and the new M3/M4 revealed before that also polarized. What can't be denied is the engineering prowess that goes into the creation of every M car, and now we have another new one to look forward to. According to an insider on the Bimmerpost forum, BMW is busy prepping a limited edition derivative of the M4 Coupe.

The source says that this special M4 will only be produced for a few months, starting in November next year. Apparently, it will be configured like the lightweight CSL but, crucially, it will come with a manual gearbox. When details about the upcoming CSL were shared last month, we found out it would only come with an automatic transmission, so this limited M4 with a manual instantly becomes an ultra-desirable prospect. Like the CSL, expect options like parking sensors, electric seats, and comfort access to be removed.

Of course, the BMW M division will celebrate its milestone 50th anniversary next year. In line with this, we expect a lot of surprises from the company as it looks back on icons like the M3 and M5, while forging ahead with new products. The special M4, whatever it is called, could potentially be badged as a 50 Jahre model, or 50th Anniversary Edition. This is purely speculative, but what's for certain is that a CSL-esque M4 with a manual transmission is a recipe for something special.

The well-known 3.0-liter twin-turbo inline-six could be tuned to produce close to 550 horsepower, and with less weight, that should make it deliciously quick and agile. We should find out more in the months ahead, but 2022 is shaping up to be a huge year for BMW M.
