Think the old M4 GTS was hardcore? Just wait.
BMW's M division clearly sees a market for even more extreme and powerful vehicles beyond its existing and impressive arsenal. The latest example is the new M5 CS and more are coming soon, such as the M3 and M4 Competition xDrive models. Production for both could get underway as soon as this July, but already there's talk regarding the launch of an even more hardcore M4, the M4 CSL.
According to a longtime member of the Bimmer Post forum, BMW M4 CSL production could get underway in July 2022. As was the case with the previous generation M4 GTS, the CSL is will be coupe only and will have a "very short production run."
Just 700 examples of the GTS were made, just to give an indicator. Less than 1,000 is very likely once again. But unlike the M4 Competition, the M4 CSL will probably be rear-wheel-drive-only and equipped with a six-speed manual transmission. All-wheel drive systems and automatic gearboxes add weight, the ultimate enemy for track-focused models like the M4 CSL. Additional weight-saving mechanisms will be accomplished with generous amounts of carbon fiber and the elimination of the rear seat and some sound-deadening materials.
Exterior modifications should include things like a large rear wing, redesigned front splitter and rear diffuser, upgraded exhaust system, and unique wheel designs.
Under the hood, the G82 M4's S58 3.0-liter twin-turbocharged inline-six will remain, though numerous modifications are expected. The CSL will certainly be more powerful than the current 473 horsepower and 406 lb-ft of torque, as well as the M4 Competition's predicted 503 hp and 479 lb-ft of twist. We wouldn't be shocked to see at least 530 hp and 500 lb-ft.
If the summer 2022 production start date turns out to be accurate, then chances are a full reveal will happen about a year from now. Whether that will be at a live auto show or online-only remains to be seen.
