Other than the V-12–powered 760Li, every 7-series model will see significant upgrades to its powertrain. The 750i (and long-wheelbase 750Li) still use a twin-turbo 4.4-liter V-8, but BMW has added Valvetronic—its variable valve timing and lift system—to this engine. It helps pump up output from last year’s 400 hp and 450 lb-ft of torque to 445 and 480.
