The S55 features aluminum cylinder heads, direct ignition, and a balance shaft to reduce vibration. Air goes through multipoint injection with a plenum chamber located directly at the intake valves and then passes through a hollow intake manifold to the individual cylinders.
A mixture of air and fuel is fed into each cylinder separately using an angled throttle body (2 in each bank). This gives the engine its distinctive “boxer jacket.” The intake valves are actuated by BMW’s Valvetronic variable valve timing, while ball bearings operate the exhaust valves.
The BMW S55 engine uses torque-converter automatic transmissions with multiple clutches and planetary gear sets. The S55 has been developed with the ability to cope with high revving, high-load driving duties. You can choose between manual or automatic transmissions (5/5/5 speed).
