Shortly after unveiling the new G11/G12 BMW 7 Series LCI (facelift in BMW speak), BMW revealed more details about their flagship plug-in hybrid variants – 745e, 745Le and 745Le xDrive.
Starting from the base model , the plug-in hybrid system uses a 3.0 litre turbocharged straight-six engine with 286 PS and 450 Nm compared to the previous 740e, 740Le and 740Le xDrive that packed a 2.0 litre turbo four-pot.
Meanwhile, the eDrive aspect is of the powertrain is unchanged, with an electric motor being integrated into the eight-speed Steptronic gearbox, which not only provides drive but also doubles as a generator to recuperate energy during braking and coasting phases. A slight tweak here is the e-motor’s output that is now 113 PS and 265 Nm, the latter being a 15 Nm improvement.
Powering the e-motor is a more substantial 12 kWh lithium-ion battery (pre-LCI models packed a 9.2 kWh unit) placed underneath the rear seats. The battery is also used to run the car’s onboard network as well as auxiliary systems like air-conditioning.
For their peformance figures, the 745e takes 5.2 seconds to get from zero to 100 km/h, while the 745Le takes 5.3 seconds, and the 745Le xDrive at 5.1 seconds. All variants are electronically-limited to 250 km/h by default.
BMW notes the 7 Series PHEV variants are available with the Pure Excellence or M Sport trim package, along with a range of driver assistance systems and optional equipment, except the Executive Drive Pro active roll stabilisation package.
