The BMW N54 is a twin-turbocharged straight-six petrol engine that was produced from 2006 to 2016.[1] It is BMW's first mass-produced turbocharged petrol engine and BMW's first turbocharged petrol engine since the limited-production BMW M106 was discontinued in 1986. The N54 debuted at the 2006 Geneva Motor Show and was launched in the 335i model of the E90/E91/E92/E93 3 Series range.
Following the introduction of its BMW N55 successor in 2009, the N54 began to be phased out. The final model powered by the N54 is the E89 Z4 roadster, which was produced until 2016.
The N54 has won six straight International Engine of the Year awards[2] and three straight Ward's 10 Best Engines awards.[3]
There is no BMW M version of the N54, however a high-output version of the N54 is used in the 1 Series M Coupe, Z4 35iS and 335iS models.
