The BMW 7-Series comes in two trims, 740i and 750i xDrive. The 740i is powered by a 3.0L turbocharged 6-cylinder engine that produces 320 hp and power is sent to the rear wheels via an 8-speed automatic transmission. The 750i xDrive is powered by a 4.4L twin-turbocharged, V8 engine making 445 hp. An 8-speed automatic feeds the power to all four wheels. Both trims feature quick acceleration times, but the 750i xDrive claims an impressive 0-60 time in the low 4-second range. The BMW 7-Series is replete with new technology. The grill features active aerodynamic fins that can automatically open when cooling is needed, or stay shut to improve fuel economy. Auto-leveling air suspension is standard on the 7-Series, a feature that actively works to improve both ride quality and handling. Drivers may modify suspension settings on the fly to provide improved feel and response or to soften and gain comfort as the road and driving conditions permit. The touch- screen interface now responds to gesture commands as well as the conventional voice commands or BMW's iDrive controller. Standard features on the 740i are as plentiful as would be expected on a luxury sedan at this price. LED headlights and fog lamps are standard as are 18-inch alloy wheels, heated and power folding side mirrors. Seats 10-way power adjustable, heated and covered in leather. The interior features wood trim, a Harman/Kardon 600-watt 16-speaker sound system with a 10-inch touchscreen that integrates navigation and a rearview camera. A year-long subscription to SiriusXM satellite radio is also included. Automatic 4-zone climate control, dynamic cruise control, a power opening and closing trunk, a panoramic moonroof, rain sensing windshield wipers, park distance control (both front and rear) and wireless charging are also included as standard. The 750i xDrive includes a bigger engine and all-wheel drive, but it also offers a hill-descent mode for loose surfaces, larger 19-inch wheels, 20-way power adjustable front seats, Napa leather upholstery and a full heads-up display. Options on the 7-Series include an executive package with vented and massaging front seats, an Autobahn package with more suspension and steering and an M-Sport package that offers unique badges and styling cues for a more performance-oriented look. Rear-seat enhancement packages are also available that can add such features as massaging and reclining rear seats with footrest and a rear seat entertainment system that comes with its own 7" tablet.
