n62

The N62 is a V8 piston engine manufactured by BMW. It was produced from 1998 to 2007 and featured in many of BMW's luxury sedan and coupe models. The engine is known for its smooth power delivery and sophisticated technology for its time.

Key features of the N62 include its aluminum construction, variable valve timing (VANOS), and variable valve lift (Valvetronic) on some variants. These technologies aimed to improve both performance and fuel efficiency. The N62 was offered in various displacements, ranging from 3.6 liters to 4.8 liters.

Common applications for the N62 engine include the BMW 5 Series (E60/E61), 7 Series (E65/E66), and X5 (E53). It powered models such as the 540i, 550i, 740i, 750i, and X5 4.8is. The engine was generally well-regarded for its performance and refinement, contributing to the driving experience expected from BMW vehicles of that era. Over its production run, BMW made incremental updates to the N62 to enhance its reliability and efficiency. Despite its advanced features, like many complex engines, the N62 has some known maintenance points that owners and mechanics should be aware of, particularly related to its valve stem seals and cooling system components.
