The BMW 420i was a variant of the F32 BMW 4 Series that was introduced for the 2014 model year. The 420i was offered in coupe, convertible, and Gran Coupe (sedan) body styles. Initially, these cars were powered by BMW's 2.0L N20 turbocharged inline four engine, but for the 2017 model year, the updated 2.0L B48 turbocharged inline four was used. Both of these engines had an output of 181hp, but the B48 had slightly more torque. Drive from either engine was sent to the rear wheels, through manual or automatic transmissions. Production of the F32 BMW 420i lasted until 2019, but the model series would continue life in the next generation G22 BMW 4 Series.
