BMW N54

The BMW N54 is a direct injection turbocharged straight-6 DOHC engine which began production in 2006 and presently (2015) remains in production in the E89 Z4 sDrive 35is. It debuted at the 2006 Geneva Motor Show and was launched in late 2006 in the E92 335i. The N54 began to be phased out following the introduction of the N55 in 2009.

The N54 has won five straight International Engine of the Year awards, and three straight Ward's 10 Best Engines awards.

Models

N54B30 (225 kW version)

For the E90/E91/E92/E93 3-Series, the N54 engine was used in the 335i model from 2006 onwards. In the 3-series, it therefore replaced the 330i (which used the naturally aspirated N52B30 as the performance model below the M3).

This version is rated at 225 kW (302 hp) and 400 N·m. However, independent testing has resulted in estimates of 332 hp (248 kW) and 311 lb·ft/422 N·m.
