Preeminent German tuner Manhart Performance has pulled the silks from a bespoke M4 CSL – the Manhart MH4 900 – that pumps out a Ferrari SF90 Stradale-baiting 922 horsepower! All done without an engine swap and with meticulous fettling of the BMW’s original 3.0-liter twin-turbo straight-six. It’s yet more proof that the BMW B58 and S58 six-cylinder engines are the closest things we’ve got to a modern 2JZ engine.
