The 2015 BMW X4 is a four-door crossover with coupelike styling. There are two trim levels: xDrive 28i and xDrive 35i. The "xDrive" moniker indicates all-wheel drive, while the numbers denote whether the engine is a turbocharged four-cylinder (28i) or a turbocharged-six (35i).
The X4 xDrive 28i comes standard with 18-inch alloy wheels, a sunroof, a power tailgate, adaptive xenon headlights, LED foglights, LED running lights, power-folding mirrors, automatic wipers, cruise control, dual-zone automatic climate control, "SensaTec" (premium vinyl) upholstery, a tilt-and-telescoping leather-wrapped steering wheel (with paddle shifters on automatic-transmission models), eight-way power front seats, 40/20/40 split-folding rear seatbacks and auto-dimming mirrors. Standard electronic features include Bluetooth phone and audio connectivity, BMW Assist eCall emergency telematics, BMW's iDrive electronics interface with a 6.5-inch display and a nine-speaker sound system with a CD player, HD radio and a USB/iPod interface.
Aside from its more powerful six-cylinder engine, the xDrive35i adds 19-inch wheels.
There are a number of option packages available for the X4. The Premium package includes keyless ignition and entry, leather upholstery (available separately), front seat power lumbar adjustment and satellite radio. The Cold Weather package includes a heated steering wheel and heated front and rear seats. The Lighting package features full LED headlights with automatic high beam control.

The M Sport package adds 19-inch wheels (for the 28i), styling tweaks that include "Shadowline" (black-out) window trim, front sport seats, a sport steering wheel and a choice of aluminum and wood cabin accents.
