Leica claims the new Leica M11 can produce 3 different output resolutions, both in JPEG and RAW. This could lead to think that the camera uses some CFA that allows for pixel binning techniques to produce different resolutions. But the sensor happens to be a standard 60Mpx RG/GB Bayer sensor (which BTW is the most logical way in order to prioritize image quality at the highest resolution), so the 36Mpx and 18Mpx shooting modes should just be downscaled versions of the 60Mpx demosaiced RAW data.
I am a bit surprised at why Leica is putting so much effort in marketing these lower resolution modes, claiming an improvement in SNR and DR, which is a common consequence of any pixel downsizing procedure.
