Four trim levels comprise BMW’s X5 series of SUVs: the sDrive 35i, xDrive 35i, xDrive 35d, and xDrive 50i. A 3.0-liter turbocharged six-cylinder engine powers the 35i, delivering 300 hp and 300 lb-ft. Under the hood of the 35d, you will find a similar 3.0-liter turbodiesel six-cylinder engine, producing 255 hp and 413 lb-ft. The cream of the crop is the 50i, boasting a 4.4-liter turbocharged V8 engine which throws out 445 hp and 480 lb-ft. sDrive rear-wheel-drive is standard on the 35i, while the xDrive four-wheel drivetrain which is standard on the 35d and 50i, is also available as an optional replacement. Standard on every model and with any engine/drivetrain combination is an eight-speed automatic transmission.
The 35i and 35d come equipped either 19 or 20-inch alloy wheels, bi-xenon headlights, fog lights, LED daytime running lights and taillights, dual-zone climate control, power accessories, premium vinyl upholstery, a panoramic glass sunroof, cruise control, 14-way power front seats with power lumbar settings, a 10.2-inch central display, navigation, a nine-speaker sound system with two subwoofers, AM/FM/CD/MP3 playback and Bluetooth compatibility, a trip computer, a rearview camera, and parking assist. The 50i upgrades the upholstery to leather and adds four-zone climate control, keyless entry and ignition, a 16-speaker Harman Kardon sound system, Sirius XM, and front and rear parking sensors. As with all BMW models though, getting the most out of it requires the addition of options, both in standalone and package guise.
