Two plug-in hybrid (PHEV) versions of BMW’s flagship 7-Series has been revealed, with performance, technology and luxury coupled to short-distance emissions-free capability.
The plug-in hybrids the sportiness, comfort and feel-good ambience of BMW’s flagship luxury models with increased efficiency.
There is a choice of two model variants: the BMW 745e and the BMW 745Le xDrive, the latter of which gets intelligent all-wheel drive.
The plug-in hybrid system consists of a six-cylinder in-line gasoline engine and an advanced high-voltage battery with an enlarged capacity compared to previous plug-in models.
This gives a boost in power output and torque, as well as improved figures for electric range, fuel consumption and CO2 emissions.
Power comes from a 3.0-litre BMW EfficientDynamics engine producing a peak power output of 286 hp combined with an electric motor along with a new lithium-ion battery featuring the very latest battery cell technology and expanded storage capacity.
In SPORT mode, the two power sources combine to give a total power output of 394 hp and maximum torque of 442 lb/ft, giving the 745e sports car-like acceleration.
The hybrid system features intelligent energy management for precisely controlled interaction between the two power units, including a preview function that works with the car’s GPS to assign electric power most efficiently on a pre-planned route.
In performance terms, the 745e accelerates from 0-100 km/h in 5.2 seconds. The new 745Le xDrive, with its intelligent four-wheel-drive, cuts that time down to just 5.1 seconds, with all three models electronically limited to a top speed of 155 mph.
The new high-voltage lithium-ion battery for the plug-in hybrid 7-Series has an increased capacity of 12.0 kWh, allowing electric power to be enjoyed beyond the city limits.
In HYBRID mode, all models can travel at a speed of up to 68 mph – 13 mph faster than the predecessor models – in purely electric mode.
