The '''BMW N20''' is a turbocharged four-cylinder petrol engine which replaced the [[BMW N53|N53]] (or [[BMW N52]] in some markets) and has was produced from 2011-2017. 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.<ref>{{cite web|url=http://www.cbt.com.my/2012/02/09/n20-series-engines-bmw-goes-for-less-delivers-more/ |title=N20 series engines – BMW goes for less, delivers more |website=www.cbt.com.my |deadurl=yes |archiveurl=https://web.archive.org/web/20131026011700/http://www.cbt.com.my/2012/02/09/n20-series-engines-bmw-goes-for-less-delivers-more/ |archivedate=26 October 2013 |df= }}</ref>

The BMW N20 is a turbocharged four-cylinder petrol engine which replaced the N53 (or BMW N52 in some markets) and was produced from 2011-2017. 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.
