2021 BMW 545e xDrive Sedan - Drive, Interior and Exterior. Please Consider Subscribing.
The new BMW 545e xDrive Sedan features a synchronous electric motor delivering a maximum power output of 80 kW/109 hp, which is combined with an efficient straight six-cylinder petrol engine with BMW TwinPower Turbo Technology and 210 kW/286 hp, together generating an overall system output of 290 kW/394 hp. Power is distributed as required to all four wheels via an 8-speed Steptronic transmission and intelligent BMW xDrive four-wheel drive. Maximum system torque is 600 Nm and top speed is reached at 250 km/h, whilst a speed of 140 km/h is possible in purely electric operation. From a standstill, the new BMW 545e xDrive accelerates to a speed of 100 km/h in just 4.7 seconds*. Thus, the BMW 545e xDrive clearly excels as the most dynamic of all BMW six-cylinder plug-in hybrids.
Thanks to intelligently controlled interaction between both drive systems, the new BMW 545e xDrive combines the best of two worlds. It facilitates not only purely electric driving in urban traffic and efficient commuting between home and the workplace, but also excels through dynamic performance and comfortable long-distance travel. With a purely electric range of 54–57 kilometres* and an average fuel consumption of 2.4–2.1 litres/100 km*, the new BMW 545e xDrive combines brand-typical driving dynamics and a high level of long-distance ride comfort with extremely efficient use of resources.
The latest plug-in hybrid model of the BMW 5 Series is fitted with a 400V lithium-ion battery which is positioned under the rear seat in order to save space. With a luggage volume of 410 litres, the transport capacity of the BMW 545e xDrive is only slightly smaller than of those model variants which are fitted with a conventional engine.
In order to make optimum use of the combination of the straight six-cylinder engine featuring ultra-smooth running characteristics and eDrive technology in all driving situations, the BMW 545e xDrive supports the driver in numerous ways in terms of energy management. Various driving modes, some of which can be individualised in their operation, are simply selected by pressing the corresponding button on the centre console.
The HYBRID mode is the default setting, which ensures a balanced set-up and an intelligent interaction between combustion engine and electric motor. It is also possible to select ELECTRIC mode as the standard setting via the iDrive menu. In HYBRID mode, the electric motor is predominantly used. The combustion engine only kicks in at higher speeds or under intensive load conditions. Since the system is linked to the navigation system, the interaction between combustion engine and electric motor can be adapted more precisely to the route profile, topography and other driving situations in an anticipatory manner. The electric range is increased by recuperation in overrun and braking phases. The energy supply saved in this way can then be used specifically for locally emission-free driving through urban areas and the arrival at the defined destination.
By pressing the HYBRID button twice, an efficiency-optimised version of this operating mode (HYBRID ECO PRO) is activated.
The coasting function on the overrun, among other things, contributes to a further reduction in consumption. The navigation and sensor data-supported control system also optimises the effectiveness of braking energy recovery. When approaching a junction or a vehicle driving ahead, for example, infinitely adaptive recuperation can be put to particularly intensive use for the purpose of deceleration.
In SPORT mode, the electric motor supports the straight six-cylinder petrol engine when the overall system output of 290 kW/394 hp is fully needed. The set-up is designed for dynamic performance, and the gearshift program is sporty.
The ELECTRIC mode, on the other hand, enables locally purely emission-free driving up to 57 kilometres* and up to 140 km/h.
