New BMW M3 CS Details Leak With 543 HP and AWD
As seen in these leaked documents uploaded to the Bimmerpost forums, the G80-generation M3 CS will pump out 543 hp from its S58 inline-six and come with xDrive all-wheel drive. Matching that of the sublime M4 CSL, that’s 40 more hp than the 503-hp M3 Competition. The model will apparently be built in both left- and right-hand-drive European spec as well as left-hand-drive for the U.S. The uploader alleges production will begin in March 2023.
In addition to boasting more power and torque, the last-gen M3 CS was lighter, used a specifically tuned sports exhaust, and was limited to 1,200 units. Its roof, front splitter, rear lip spoiler, and rear diffuser were made of carbon fiber-reinforced plastic. It’s safe to expect this new one will get a similar treatment. The accompanying image is pixelated in these docs, so we can’t quite see what the upcoming car will look like, but one could form a fairly educated estimate based on what the previous-gen M3 CS looked like versus its regular counterpart.
When Deputy Editor Kristen Lee got her hands on the standard M3 last October, she found a sport sedan that was highly capable but also “a bit too digitized for its own good.” Based on our experience with the CS-branded cars in the M5 CS and M2 CS, though, we won’t be surprised in the slightest if this version of BMW’s venerable high-performance 3er fixes those tactility qualms.
We’ve reached out to BMW for comment and will update this story when we hear back.
