The BMW X7 comes with one of two engines. The xDrive40i is powered by a 3.0L 6-cylinder engine fed by a turbocharger, sending power to all-four wheels via an 8-speed automatic. BMW claims the X7 xDrive40i makes 335 horsepower, which is enough get the vehicle to 60 miles per hour in just 5.8 seconds, so despite not having overwhelming amounts of horsepower on paper, the xDrive40i is pretty quick. For those wanting more power, the M50i is powered by a 4.4L twin-turbocharged V8 making 523 horsepower. Regardless of which engine is ordered, the X7 comes in two basic flavors dubbed Luxury and M Sport. From the outside, the two trim levels couldn't be more different, the Luxury features plenty of exterior brushed aluminum around the windows and the lower door sills, while the M sport features more aggressive wheels, blacked out aluminum and bigger grill openings in the front fascia. Regardless of trim level, the X7 is generous with its standard features, which include 21-inch wheels, adaptive LED headlights and LED fog lights. Inside, the X7 comes standard with 16-way heated power front seats, a 10-speaker sound system with HD radio and SiriusXM satellite radio, a heated leather wrapped multifunction steering wheel, BMW ConnectedDrive services, cruise control, a panoramic moonroof featuring a 2-piece glass panel, 4-zone automatic climate control, rain sensing wipers, a power tailgate, park distance control, and BMW's extended ambient lighting system.
