BMW‘s upcoming M4 CSL coupe, expected to be both lighter and more powerful than the regular M4 Competition, is just around the corner now.
In the lead up to its May 20 reveal at the Concorso d’Eleganze Villa D’Este event in Italy, BMW M has once again posted a number of teaser images to its Instagram account showing different aspects of the M4 CSL.
At the moment the Bavarian automaker is publishing a new teaser image each day, with one of the first teaser images in this set showing the M4 CSL hidden behind the iconic E46 M3 CSL from the early 2000s.
Many of the teaser images are either extremely blurry or zoomed in to the point where you can only just make out what the photo is.
We do get another rough look at the so-called “special M headlights” that have a daytime running light signature with the typical, hexagonal shape but with a yellow-ish hue.
BMW gave us a clearer look at these in some previous teaser images, and they look very similar to those of the larger M5 CS.
In the same set of teaser images we got a glimpse at the M4 CSL’s special OLED tail lights and ducktail spoiler.
The OLED tail lights debuted in the previous-generation M4 GTS from 2016 and the ducktail spoiler is reminiscent of that of the E46 M3 CSL.
One of the more recent teaser images show off the M4 CSL’s classic BMW logo with the heritage colours, a nod to BMW M’s race cars from the 1970s.
It’s expected this classic badge will be standard on the M4 CSL as it’s currently optional on the the rest of the BMW M range.
Another teaser image depicts part of the M4 CSL’s stripped-back, M racing bucket seats. Just below the headrest on this seat there’s a ‘CSL’ badge that seems to be illuminated.
These M racing bucket seats are expected to be standard on the M4 CSL too.
CSL has classically stood for Coupe Sport Lightweight, as an English translation, and the E46 M3 CSL was 110kg lighter than the regular M3 and packed extra power and torque.
Previously spied prototypes have also been seen with a prominent chin spoiler, an aggressive aero bodykit, and a unique kidney grille with an insert that shows off a lot of the intercooler lurking behind it.
BMW is remaining tight-lipped around what’s under the bonnet of the M4 CSL but it’s expected to be a reworked 3.0-litre twin-turbo inline six-cylinder with more power and torque than the regular M4.
For context, the M4 Competition produces 375kW of power and 650Nm of torque.
A BimmerPost forum member previously wrote that the M4 CSL will reportedly produce 402kW and send power to the rear wheels only via an eight-speed automatic transmission.
BMW has confirmed the claimed combined fuel economy figure for the M4 CSL is between 9.8 and 10.1L/100km according to WLTP standards.
Production of the BMW M4 CSL will reportedly start in July 2022.
In a recent video that had a blink-and-you’ll-miss-it shot of the M4 CSL also showed a white M4 that could reportedly be an upcoming special edition called the M4 GT/H, according to the BimmerPost member.

This model could be seen with what appears to be the M4 CSL’s unique grille but with a bonnet that has black scooped-out sections and a power bulge.
It’s unclear at this stage if this bonnet will be exclusive to the M4 GT/H as we haven’t seen a clear front shot of the M4 CSL yet.
This M4 GT/H will reportedly be specified very similarly to the M4 CSL but will come with a manual transmission instead. It’ll reportedly enter production in November 2022.
