# New BMW M3 CS Details Leak With 543 HP and AWD

![](<https://www.thedrive.com/wp-content/uploads/2022/12/12/P90416677_highRes.jpg>)
*BMW*

Those looking for a more hardcore [BMW](<https://www.thedrive.com/category/bmw-news>) M3 but missed out on the [M4 CSL](<https://www.thedrive.com/car-reviews/2023-bmw-m4-csl-review-specs-price-performance-new-cars>) boat are in luck because BMW may be preparing a new M3 CS with the same horsepower.

As seen in [these leaked documents uploaded to the *Bimmerpost* forums](<https://g80.bimmerpost.com/forums/showthread.php?t=1976363>), 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](<https://www.thedrive.com/news/theres-another-aftermarket-fix-for-the-big-bmw-m4-grille>). 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](<https://www.thedrive.com/new-cars/42184/2021-bmw-m3-review-the-benchmark-gets-faster-but-leaves-a-lot-behind>), 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](<https://www.thedrive.com/new-cars/42576/2022-bmw-m5-cs-review-just-what-the-real-m-fans-ordered>) and [M2 CS](<https://www.thedrive.com/new-cars/42161/2020-bmw-m2-cs-review-bmws-best-modern-car-is-still-incredible>), 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.
