In addition, the N63 engine block features a double-VANOS variable valve timing system. This technology adjusts the timing of the intake and exhaust valves based on engine speed and load, allowing for optimal power output and emissions reduction. The system also includes a maintenance-free, solenoid-controlled oil pump, which ensures consistent oil pressure for optimal engine performance.

The engine block also includes a number of advanced features designed to enhance durability and reliability. These include a cast-iron crankshaft, forged connecting rods, and forged pistons. The engine block is also equipped with a dry sump oiling system, which keeps the oil cool and ensures consistent lubrication under high-performance conditions.

In summary, the BMW 4.4L V8 N63 Twin-Turbo Engine Block is a marvel of modern engineering, delivering power, efficiency, and refinement in equal measure. Its advanced features, including twin-turbocharging, High Precision Direct Injection, and double-VANOS variable valve timing, make it a standout performer in its class.
