If you believe in lucky numbers, the 7th generation BMW 7-Series is a good omen. Available with three different drivetrains (including the all-electric i7) it'll appeal to a wide number of buyers… so long as they're wealthy. Tom Voelk checks out the 760i xDrive model that gets it's oomph from a 4.4-liter twin turbocharged V8, plus an electric motor embedded into the 8-speed transmission since ICE 7-Series are 48V mild hybrids now. And then there's the Rear Executive Lounge Seating which just begs for a classical music montage.
