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.
As per the 3.0 litre version of the naturally aspirated BMW M54, all models have a bore of 84 mm (3.3 in), a stroke of 96 mm (3.8 in), a capacity of 2,979 cc (181.8 cu in) and a compression ratio of 10.2:1.
For the E90/E91/E92/E93 3-Series, the N54 engine was used in the 335i model from 2007 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.
Applications:
A variant of the N54B30 with higher power and torque (but a slight reduction in low rpm torque) is used in the F01 740i and E92 335is.
Applications:
The most powerful version of the N54 is found in the E89 Z4 sDrive 35is (as of 2016, the only application of the N54 still in production) and the 1 Series M Coupe.
