BMW has seen fit to equip every X4 with all-wheel drive and an eight speed automatic transmission. The 28i model uses a turbocharged 2-liter four-cylinder with 240 horsepower, while the 35i gets a 3-liter six-cylinder turbo good for 300 horsepower. Otherwise, there is virtually no difference between the two models.
The X4 starts out with a good deal of equipment, including adaptive xenon headlamps, wood or aluminum interior trim, power front seats with driver memory (leatherette), a sunroof, a power tailgate, rear parking sensors and a 12-speaker sound system with HD radio.
You can select one of two optional trim lines to finish off your X4. The xLine carries lightweight Y-spoke 19-inch wheels, dark copper exterior trim and specific interior finishes. The M Sport line gets its own 19-inch wheels, an aerodynamic body kit and sportier trim details throughout.
Leather seating is part of the Premium Package, which also includes satellite radio and keyless access and ignition. The Cold Weather Package adds heated front and rear seats, a heated steering wheel and retractable headlamp washers.
The Technology Package includes a head-up display, integrated smartphone apps and a navigation system (also available separately). You get front parking sensors and a rearview camera with the Driver Assistance Package, while Driver Assistance Plus tacks on a surround-view camera system, active collision mitigation, and blind-spot and lane-departure warning systems. Adaptive cruise control can be added to the package at additional cost. Rounding out your choices are adaptive full LED headlamps and active suspension dampers for increased stability around curves.
