BMW has unveiled the 2014 BMW X5, revealing a silhouette that hasn't changed much since the last model year. Key modifications include large dual kidney grilles that touch the optional LED adaptive headlights, plus rear "aero blades" and new drag-reducing "air curtain" apertures that direct air around the wheel arches. The biggest change is the available sDrive35i trim, representing the first rear-wheel drive version of the crossover to date. All-wheel drive is still standard, and power for both options comes from a 3.0-liter turbocharged inline six-cylinder engine, mated to an eight-speed automatic transmission. The power output is rated at 300 horsepower and 300 lb-ft of torque, enabling a 0 to 60 mph sprint time of 6.2 seconds. The luxury interior features Dakota leather seats, LED ambient lighting and freestanding 10.2-inch iDrive display, plus gloss black accents and Poplar Grain wood trim. Expanded dimensions have resulted in a cargo area increased 7 percent to 66 cubic feet. Additional options include a third row seat, Harman Kardon or Bang & Olufsen audio system and a rear seat entertainment system with two tablet-style displays. Delivery of the 2014 BMW X5 is scheduled for November.
