BMW M750Le to inaugurate M Performance plug-in hybrids?
The sedan is expected to deliver more than 550 horsepower.
BMW is reportedly working on an M750Le, kicking off a series of promised M Performance plug-in hybrids.
Rumors posted by BMWBlog suggest the M750Le will be powered by BMW's B58 3.0-liter straight six, potentially tuned to deliver around 400 horsepower, while an electric motor is expected to bump total system output to more than 550 horsepower and 590 pound-feet of torque.
If the speculation is accurate, the M Performance hybrid powertrain fits between the Porsche Panamera's 457-horsepower E-Hybrid configuration and 677-horsepower Turbo S E-Hybrid range-topper.
BMW is said to planning the M750Le for both long- and short-wheelbase variants, while a standard 745Le might slot below the M Performance trim with 80-100 fewer horsepower.
The next-generation 7 Series is rumored to be on track for a 2021 arrival, though it is unclear if the plug-in powertrains will be available at launch.
