What engine does the BMW X3 use?
2 Answers
BMW X3 is equipped with the BMW B-series B48 2.0T turbocharged engine, which is a 4-cylinder engine featuring TwinPower twin-scroll single turbocharger, high-precision direct injection system, Double VANOS dual camshaft variable valve timing system, and VALVETRONIC fully variable valve control system. The BMW X3 is an SUV model with distinctive personality, introducing the new concept of a Sports Activity Vehicle (SAV), and is equipped with BMW's patented xDrive intelligent all-wheel-drive system. This vehicle measures 4648mm in length, 1881mm in width, 1661mm in height, and has a wheelbase of 2810mm.
Over the years running my repair shop, I've handled many BMW X3 models and found this generation's engines to be quite sophisticated. The entry-level xDrive25i uses a B48B20 2.0L turbocharged four-cylinder with 184hp, perfectly adequate for daily commutes. The mainstream 30i variant shares the same displacement but is tuned to 252hp, delivering particularly responsive urban driving. The performance-oriented X3 M40i upgrades to a B58 3.0L inline-six turbo pumping out 387hp for exhilarating acceleration, paired with ZF's 8AT transmission for swift and smooth shifts. The range-topping X3 M features the track-bred S58 engine with twin turbos producing 510hp. The latest models even offer hybrid options like the xDrive30e's 2.0T+electric motor combo delivering 55km electric range and ultra-low 1.7L/100km fuel consumption. All these powerplants employ twin-scroll turbos and high-pressure direct injection, with 95-octane fuel recommended as minimum.
