BMW N55
The BMW B58 is a turbocharged straight-six engine, which began production in 2015.[1] The B58 replaced the N55 and was launched in the F30 340i.[2]
The B58 is part of BMW's modular engine family, each engine using a displacement of 500 cc (30.5 cu in) per cylinder, following the B38 and B48 engine.[3]
The B58 engine was named to Ward's World's 10 Best Engines four times, in 2016 (installed in the 340i),[4] 2017 (M240i),[5] 2019 (X5)[6] and 2020(M340i).[7]
The S58 engine, which was released in early 2019, is the high-performance version of the B58.[8][9] It was named to Ward's World's 10 Best Engines in 2023 (installed in the M2).[10]
