BMW reserves its finest materials for the 7 Series, including loads of high-end wood and leather trim.

Options include the Autobahn package (variable-ratio steering and the camera-based Active Comfort Drive with Road Preview system that anticipates changing road conditions and adjusts the dampers accordingly) and the Cold Weather package (heated steering wheel and heated front and rear seats). There's also a pair of safety packages, starting with the Driver Assistance Plus package (lane departure warning, speed limit info, automated parking, blind-spot monitoring, frontal collision mitigation with automatic braking and a surround-view camera with driver-selectable camera views) and graduating to the Driver Assistance Plus II package (adaptive cruise control, lane departure prevention and Traffic Jam Assistant).

The Executive package adds a head-up display, power rear sunshades, ceramic-trimmed controls and multicontour front seats with additional power adjustments. The Luxury Seating package adds heated armrests and ventilated massaging rear seats that slide and recline.

Stand-alone options include some of the above items plus 20-inch wheels, summer tires, a cabin perfume diffuser, a wood and leather steering wheel, a large dual-pane sunroof with LED accents in a handful of selectable colors, a night-vision camera system and a 16-speaker Bowers & Wilkins surround-sound audio system.

The 750i includes a few additional standard luxuries relative to the 740i, while the 740e will have its own roster of hybrid-oriented features. The M760i offers all that, but with a twin-turbo V12 engine and standard all-wheel drive.

The 2017 BMW 740i is motivated by a turbocharged 3.0-liter inline-6 engine rated at 320 horsepower and 332 pound-feet of torque. The 2017 740e xDrive pairs a turbocharged four-cylinder engine with an electric motor backed by a lithium-ion battery, with an expected total output of around 325 hp, while the 750i upgrades to a turbocharged 4.4-liter V8 engine (445 hp, 480 lb-ft). At the top, the M760i is equipped with a monstrous turbocharged 6.6-liter V12 (601 hp, 590 lb-ft).

Rear-wheel drive is standard on the 740i and 750i, with xDrive all-wheel drive optional there and standard on the 740e and M760i. Every 7 Series employs an eight-speed automatic transmission.

In Edmunds track testing, a 750i launched from zero to 60 mph in a suitably swift 4.5 seconds. BMW estimates the M760i will reach 60 mph in a breathtaking 3.7 seconds
