1974 BMW 3.0 CS With An M5 Engine
CARCOOPS:Power is provided by a naturally aspirated six-cylinder engine which was sourced from an E34 M5. SpeedKore didn’t go into specifics, but the S38 engine had displacements of 3.5- and 3.8-liters depending on the model year and market.
Assuming the engine was pulled from a US-spec M5, it’s likely a 3.5-liter inline-six developing 311 hp (232 kW / 315 PS) and 266 lb-ft (360 Nm) of torque. Regardless, it’s mated to a four-speed automatic transmission
