A midsize crossover SUV, the 2016 BMW X5 comes in 35i, 35d, 40e and 50i trim levels. All have all-wheel drive (xDrive), though there is also a rear-drive version of the 35i available (s Drive). The 40e is the new plug-in hybrid model and arrives later in the model year. (The high-performance X5 M is reviewed separately.) Five-passenger seating is standard, and an optional third-row seat increases capacity to seven. Standard equipment for the 35i and 35d includes 19-inch wheels, adaptive xenon headlights, LED fog lights, power-folding and auto-dimming mirrors, automatic wipers, a panoramic sunroof, a power liftgate, roof rails, front and rear parking sensors, dual-zone automatic climate control, a power tilt-and-telescoping steering wheel, 'Sensa Tec' premium vinyl upholstery, heated 10-way power front seats (with four-way power lumbar) and driver memory settings. Electronics features include BMW Assist, Bluetooth phone and audio connectivity, a 10.2-inch central display screen, the iDrive controller, a navigation system, voice controls, traffic reporting and a nine-speaker sound system with a CD player, USB and auxiliary audio inputs and HD radio. Look for a very similar equipment list on the xDrive 40e, which also gets standard adjustable suspension dampers and rear air suspension (optional on all other X5s) along with hybrid-specific instrumentation and additional iDrive menu items. The X5 sDrive35i (rear-wheel drive) and xDrive35i (all-wheel drive) models feature a 3.0-liter turbocharged inline six-cylinder engine that produces 300 horsepower and 300 pound-feet of torque. As with all other X5s, the 35i models come with an eight-speed automatic transmission, and the xDrive versions include hill descent control. Every 2016 BMW X5 includes stability and traction control, antilock brakes, automatic brake drying, front side airbags, side curtain airbags and active head restraints. Also standard are the BMW Assist and Remote Services emergency communications systems, which provide automatic crash notification, stolen vehicle recovery, remote lock/unlock and on-demand roadside assistance. The optional Driver Assistance package adds a rearview camera and a head-up display, while the Driver Assistance Plus package adds to those items blind-spot monitoring, a top-down camera system, lane-departure warning, speed limit info and a frontal collision warning and mitigation system with pedestrian detection that can apply the vehicle's brakes automatically to prevent or minimize an impact at low speeds.
