The story

History: facts, each with its source

The B58 replaced the N55 and began production in 2015, with a closed-deck aluminium block and a single twin-scroll turbo. Wikipedia lists it in the F30 340i from 2015, the G20 M340i from 2019 and the Toyota Supra from 2019.1

BMW Tuning calls it one of the most reliable engines BMW has ever made, with problems far less common than on its earlier turbo sixes.2
