Design edit
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]
