BMW N52
Encyclopedia
The BMW
N52 is a straight-6
engine made by BMW, which debuted in 2004 on the BMW E63 630Ci
. The N52 is BMW's 12th generation production straight-6
engine.
Its crankcase is made entirely of magnesium and aluminum, a first in the world of engine construction. BMW used Alusil
aluminum cylinder sleeves, which offer high heat conductivity, and cast them into a lightweight magnesium block
, creating one of the lightest production engines of its size class in the world at 161 kg (354 lb). It includes BMW's second generation Valvetronic
system and Double-VANOS
for fuel-efficiency (12% fuel savings over the previous generation BMW M54
engine - and increases performance). Producing 63 kW (85.5 hp) per liter of displacement, it has the lowest weight per horsepower of any six cylinder engine (1.24 hp per kilogram with the latest version).
It was awarded as one of Ward's 10 Best Engines of the Year
in 2006 and 2007. Technologically it is even more advanced than the new N54B30
bi-turbo, which is based on an older M54B30 design and lacks several improvements that BMW has made for this engine.
All BMW nameplates have been available with this engine in at least one version. Although the N52 have been replaced in some applications by the N53
(in Europe only) and biturbo N54
(for high-performance trims), both which add direct injection but do not use Valvetronic, the N52 remains a mainstay engine of BMW's lineup as of 2011, although it will be gradually replaced by the BMW N20
.
The N52B25 comes in two versions, both displacing 2.5 L (2497 cc/152 in³). The first produces 130 kW (174 hp) at 5800 rpm and 230 N·m (170 ft·lbf) at 3500-5000 rpm while the more powerful version is rated at 160 kW (218 hp) at 6500 rpm and 250 N·m (184 ft·lbf) at 2750-4250 rpm.

N52B30
The N52B30 is available in three versions, all displacing 3.0 L (2996 cc/182 in³). However, each version produces variable maximum output depending upon the application. With a common engine displacement, the output changes result from the omission of the variable resonance system, dual plenum intake runner system, and the variable back pressure muffler: 190 kW (255 hp) at 6600 and 300 N·m (221 ft·lbf) at 2500-4000 rpm is the first and most produced version, while the second one is more powerful at 195 kW (265 hp) at 6600 and 315 N·m (232 ft·lbf) at 2750-4250 rpm. The third version is just starting to replace the first 190 kW versions on the E90/E60 in late 2006 and has first been released on the new E92 330i Coupé. It will produce 200 kW (272 hp) at 6650 and 315 N·m (232 ft·lbf) at 2750-4250 rpm.Applications in the European Market (taken from BMW website 07/10/07):
