The M270 and M274 are turbocharged inline-four engines produced by Mercedes-Benz since 2011. They are the successor to the previous M266 and M271 engines respectively. The engine appeared on the Ward's 10 Best Engines list for 2017.
Design
M270 refers to the transverse configuration for front-wheel drive vehicles, while M274 refers to the longitudinally-mounted layout for rear-wheel drive vehicles.[1] Both engines are based on the same design with dual overhead camshafts, 4 valves per cylinder, variable valve timing, direct injection, and compliance with the EU6 emissions standard.[2] A 2.0 litres (1,991 cc) engine was introduced in September 2012 featuring an increased piston stroke up to 92 mm (3.62 in), increased performance figures, and a 9.8:1 compression ratio.[3] The M274 engine was also used on the Infiniti Q50 since 2014.[4]
