2022 BMW M4 CSL spy photos

Is the new-generation 2021 BMW M4 not fast enough for you? Its German maker could have a solution, with a flagship 2022 BMW M4 CSL recently spied testing for the first time. The camouflaged prototype snapped by our spy photography partners near BMW's testing centre wears a handful of upgrades over standard M4 models launched locally in recent months, headlined by a new front splitter with winglets, and a longer 'ducktail' rear spoiler.
