As of 2020, BMW’s mid-size SUV became available as a plug-in hybrid (PHEV) as an alternative to conventional petrol and diesel power. Called the BMW X3 xDrive30e, it uses both a petrol engine and an electric motor to deliver some exceptional fuel economy claims. Does it achieve them in real life, though? And how well does it perform? Find out in our full BMW X3 Plug-In Hybrid review.
