The BMW M62 engine was released to replace the M60 and was produced from 2001 to 2003. Introduced in 1999, the BMW X5 E53 quickly gained a reputation as a dynamic sports SUV and the power of the standard 4.4-liter M62B44 seemed insufficient. Therefore, it was decided to modernize it and the M62B46 engine appeared.
M62 family: M62B35, M62B44, M62B46, M62B48.
