🔧 BMW S54 3.2L DOHC I6
The BMW S54 is the naturally aspirated high-performance evolution of the M54 engine. Producing 343 hp at 7,900 rpm from 3,246cc, it was used in the E46 M3, Z3 M Roadster/Coupe, and Z4 M Roadster/Coupe. Its individual throttle bodies, flat-plane crankshaft-like balance, and high-revving character made it arguably the finest six-cylinder engine ever put in a road car.
