The M279 is a twin-turbocharged V12 engine produced by Mercedes-Benz. It was launched in 2012 with the R231 SL65 AMG.[1]

Design

The M279 is based on the previous generation M275 engine, but has been extensively revised.[2] It now features port injection, larger turbochargers, changes to the valvetrain timing, and a new exhaust system for improved efficiency and emissions.[3] The M279 also uses single overhead camshafts with 3 valves per cylinder, and has an identical bore and stroke compared to before.[4]
