The BMW 7-Series comes in several trims, 740i, 740i xDrive, 750i xDrive, 745e Plug-in hybrid and M760i xDrive. The 740i models are powered by a 3.0L turbocharged inline-six that produces 335 horsepower, with power sent to the rear wheels or all wheels via xDrive paired with an 8-speed automatic transmission. The 750i gets a 4.4L twin-turbocharged V8 engine making 523 horsepower. An 8-speed automatic feeds the power to all four wheels. The 745e plug-in hybrid pairs a 280-horsepower twin-turbocharged 3.0L straight six with a 111-horsepower eDrive electric motor, with a total output rated at 391 horsepower. BMW says the 740e will hit 60 mph in just under five seconds and the car can run purely on battery power for up to 28 miles. In the high-performance M760i xDrive, the same 4.4L twin-turbo from the 750i has been massaged to deliver 600 horsepower, while Integral Active Steering pairs variable ratio electric steering up front with rear-axle steering. BMW claims a 0-60 mph time of 3.6 seconds from the M760i xDrive. The BMW 7-Series is replete with impressive technology. The grille features active aerodynamic fins that automatically open when cooling required or close to maximize fuel economy. Auto-leveling air suspension is standard on the 7-Series. 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 all-digital touchscreen 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 is BMW's intelligent Display Key, with a touchscreen fob that reports various information about the car. Eighteen-inch alloy wheels are standard as are heated and power folding side mirrors, plus 10-way power adjustable, heated leather seating. 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 740i and 745e are similarly equipped but add BMW's sure-footed all-wheel-drive system. The 750i includes the larger engine as well as 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 badging 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-inch tablet. M Sport brakes and remote-controlled parking are also available.
