The BMW N20 is a turbocharged straight-4 DOHC petrol engine which replaced the N52/N53 and has been in production since 2011-present. Although the N20 is a straight-4, it is considered a replacement for the straight-6 N52/N53 because it powers equivalent models, producing similar horsepower to its naturally aspirated straight-6 predecessors with greater low-rpm torque and better efficiency.[1]

The N20 features a twin-scroll turbocharger, variable valve timing (called VANOS by BMW), variable valve lift (called valvetronic by BMW), direct injection, automatic stop-start[2] and an electric coolant pump. The N20 is sold alongside the smaller displacement BMW N13 turbocharged straight-4 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.
