Description
BMW E60 E64 E65 550 650 750 N62 4.8L V8 Engine
The BMW 750/650 N62 engine refers to a family of naturally aspirated V8 engines used in BMW vehicles, most commonly the 4.8L variant, which produced around 360 horsepower. These engines were notable for being BMW’s first V8 to use Valvetronic variable valve lift and a continuously variable-length intake manifold. While the term “N62” can apply to different displacements, in the context of the 750 and 650 models, it primarily refers to the 4.8L version found in cars from roughly 2004-2010.
N62 engine specifications
- Displacement: Typically 4.8L for the 750 and 650 models from this era.
- Horsepower: Approximately 360 hp.
- Torque: Around 360 lb-ft.
- Technology: Featured Valvetronic variable valve lift (replacing some throttle butterflies for efficiency and power) and a continuously variable-length intake manifold.
- Vehicle applications: Found in the BMW 750i/Li, 650i, and 550i models during this period.
Key features and considerations
- Valvetronic system: This system helped improve engine response, efficiency, and power.
- Common issue: One frequently reported problem with the N62 is valve stem seal leaks due to heat and age, which can lead to oil consumption and smoke.
- Engine management: A traditional throttle butterfly system was also included as a backup in case the Valvetronic system had an issue.
