The BMW N62 is a naturally aspirated V8 produced from 2001 to 2010, and it holds a landmark place in BMW history as the first engine to feature Valvetronic, BMW's throttle-less variable valve lift system. Displacing between 4.4 and 4.8 liters, the N62 delivered 325–367 hp and 330–360 lb-ft of torque with a 6,500 rpm redline, defining BMW's V8 character in the years just before the turbocharged era.
Engineering & Specs
The N62's headline innovation is Valvetronic, which meters intake air by continuously varying valve lift rather than relying on a conventional throttle butterfly. Combined with double-VANOS variable timing, this improves throttle response and part-load efficiency. Key figures:
- Configuration: Naturally aspirated V8, 4.4–4.8L
- Output: 325–367 hp
- Torque: 330–360 lb-ft
- Redline: 6,500 rpm
- Production: 2001–2010
The result is a free-revving, linear V8 that feels refined at cruise yet eager to climb toward redline—a distinctly different experience from the boosted N63 twin-turbo V8 that would eventually replace it.
Which BMWs Used It
The N62 powered a broad range of BMW's larger models during the 2000s:
- 5 Series: 545i and 550i
- 6 Series: 645i and 650i
- 7 Series: 750i
- X5: 4.8is
If you're unsure which V8 sits in a particular car, run the numbers through our VIN decoder to confirm the exact engine before buying. It was the eight-cylinder counterpart to the smooth inline-six N52 of the same era.
Reliability & Ownership Notes
The N62 is a rewarding engine but demands informed ownership as these cars age. Known trouble spots enthusiasts should inspect include:
- Valve stem seals — often responsible for startup smoke, a common and expensive N62 repair
- Coolant transfer pipe — an internal V-valley pipe with sealing O-rings that can leak, requiring significant labor
- Alternator bracket gasket and oil leaks — frequent age-related seepage
- Valvetronic components — motors and eccentric shaft sensors can require attention
Prioritize a documented service history and a cold-start inspection. When maintained, the N62 rewards owners with a genuinely smooth, torque-rich V8 experience.
Legacy
As BMW's first Valvetronic V8, the N62 bridged classic naturally aspirated character with modern efficiency technology. Its architecture influenced the V12 family tree of the period, including the N73 and N74 twelve-cylinders. Today it stands as one of the last great non-turbo BMW V8s—prized by enthusiasts who value linear power and a rising exhaust note over forced-induction torque.
