The Mercedes-Benz M 278 is an engine series from Mercedes-Benz and the successor to the M 273 generation. It is an 8-cylinder engine in a V arrangement . In contrast to the likewise new six-cylinder M 276 , the cylinder bank angle remained at 90 °, although the engines are closely related.

Compared to their predecessor, the engines are significantly more economical and powerful thanks to, among other things, gasoline direct injection . There is also intelligent generator management and a demand-controlled engine oil pump, fully variable injection pressure from 100 to 200 bar, biturbo charging with air-water charge-air cooling, exhaust gas turbochargers with wastegate valves, innovative cast pistons and engine electronics with controlled efficiency stop-start function. Power is transmitted via the 7- speed automatic or the AMG SPEEDSHIFT MCT 7-speed sports transmission.

The engines were introduced gradually in autumn 2010, starting with the S-Class (type 221) and the CL-Class (type 216). The AMG variant is given the designation M 157 for the turbo-charged variant and M 152 for the naturally aspirated variant with cylinder deactivation .
