In September 1998, BMW introduced the M62TUB44, including within it the
VANOS system and an electronically actuated throttle. Each bank of cylinders included a single-stage VANOS system, and only on the intake valve timing (not the exhaust valves).
The engine design also included slightly larger mass-airflow sensor and lower flow intake plenum runners which improved lower RPM torque characteristics at the cost of some high-rpm flow. Non-"TUB" intake manifolds can be transplanted onto a M62TUB44 engine to improve high (>3400) RPM torque and power characteristics (similar in effect to the swap of OBD1 manifolds onto newer OBD2 generation M52/S52). Dinan also sells this modification under a Dinan performance package (but the BMW part numbers are equivalent to stock -B44 manifolds).
- 210 kW (286 PS; 282 hp) and 440 N·m (325 lb·ft) / Electronic Throttle -SINGLE vanos;the M5 S62 was the first BMW V8 (and only E39 V8) with dual vanos. In 2002, the power was increased from 210 kW (286 PS; 282 hp) to 216 kW (294 PS; 290 hp) while torque remained the same.
