The BMW N20 is a 1.6 and 2.0 L (98 and 122 cu in) turbocharged four-cylinder DOHC petrol engine with variable valve lift and variable valve timing which replaced the N53 (or BMW N52 in some markets) and was produced from 2011 to 2017 by BMW. Although the N20 is a four-cylinder engine, it is considered a replacement for the naturally aspirated six-cylinder N52/N53 because it powers equivalent models, producing similar horsepower to the N52/N53 with greater low-rpm torque and better efficiency.[1]
The N20 features a twin-scroll turbocharger, double-VANOS (variable valve timing), Valvetronic (variable valve lift), direct injection, automatic stop-start[2] and an electric water pump. The N20 was sold alongside the smaller displacement BMW N13 turbocharged four-cylinder engine. The N20 was placed in Wards Top 10 Engines in 2012.[3]
In 2014, the N20 began to be replaced by its successor, the BMW B48.
