Motortrend has photos of a 2019 BMW X3 M driving around Los Angeles. Just like the S55 to the N55, the X3 M is supposed to have the B58's beefed up M version called the S58 also expected to be in the new G80 M3 and I have a personal hunch it may find itself in some trim levels of the next Toyota Supra.
