BMW is on a roll with their new plans for fuel efficiency. Recently, Munich announced to be preparing plug-in hybrid variants for all of its core models. To sort of exhibit this, BMW revealed the new 5-Series GT.
Although it’s not exactly new, it’s a 5-Series GT with BMW’s new plug-in hybrid eDrive powertrain. The standard gas engines also benefit from updated TwinPower Turbo systems.
BMW didn’t say how much power the new 5-Seris GT eDrive and TwinPower Turbo models produce, but they did say the new plug-in hybrid system is capable of providing up to 680hp and 750 lb-ft of torque in its most beefed setup.
You can obviously expect significantly less power in the 5-Series GT, unless BMW thought the world needed a 60hp BMW 5-Series GT. In that particular application, the models utilize a 20 kWh lithium-ion battery mounted just ahead of the rear-axle, under the rear seats. This is the best location for weight distribution, safety and the center of gravity.
A fully charged battery is capable of up to 62 miles on a single charge while the gas engine can act as a range-extending generator to produce electricity. It can also go back to the act of being a normal engine by providing power to the front-axle since the rear-axle is solely powered by the electric motor with a multi-speed gearbox. The total range for the 5-Series GT turns out to be around 370 miles.

The overall efficiency of a plug-in hybrid vehicle is closely related to its all-electric driving range. The ongoing development and refinement of hybrid drive systems under the Efficient Dynamics programme is geared in particular to maximising the amount of time the vehicle spends in electric mode. In order to ensure that this shift to increased electric operation goes hand in hand with typical BMW dynamic performance, unimpaired everyday practicality and maximum long-distance capability, the BMW Group is developing a new generation of “highly electrified” hybrid concept models.
Highlights of the future models’ Power eDrive technology will include significantly higher-powered electric motors and batteries with twice the capacity of present versions. With this technology, the BMW Group is embarking on the next stage in powertrain electrification. The development of high-performance Power eDrive electric drive technology is aimed at increasing both the overall efficiency and the dynamism of future hybrid vehicles. Increasing focus will be placed on all-electric operation – i.e. operation with zero tailpipe emissions. Power eDrive technology for plug-in hybrid application will be a natural choice for use in upmarket vehicle segments too, where it will offer unrestricted everyday practicality plus good long-distance capability.
In these plug-in hybrid vehicles of the future, the Power eDrive electric drive system will contribute approximately two thirds of the vehicle’s combined output, with the TwinPower Turbo internal combustion engine accounting for the remaining third. The drive components used in these future hybrid systems will offer combined outputs in excess of 500 kW, while the capacity of the lithium-ion batteries – up to 20 kilowatt hours – will likewise be greatly in excess of current hybrid systems.
Zero local emissions in everyday operation, instant accelerating power, superior long-distance comfort.
These advances, coupled with an increased all-electric driving range of up to 100 kilometres (62 miles), will make it possible to operate in locally emission-free all-electric mode on virtually all day-to-day trips. The role of the internal combustion engine within this concept will be a supporting one that takes various forms. For example the engine can provide a boost function when extra-dynamic acceleration is required, and it can also serve to increase the overall driving range to levels typical of a conventionally powered vehicle.
3. Growing focus on electric operation: Power eDrive plus TwinPower Turbo technology – the future of plug-in hybrid drive.
At the same time, the performance of these future hybrid models will be on a par with that of a conventionally powered sports car. To add to the excitement the new, higher-powered motors will offer a further increase in the low-end responsiveness that has always been the hallmark of electric drive.
Flexible concept for typical BMW driving pleasure.
On future plug-in hybrid concepts the electric motor, which will be the main source of power for everyday driving, will continue to drive the rear wheels, while the addition of a second electric motor driving the front wheels will create an all-electric road-coupled all-wheel-drive system. At the same time, an internal combustion engine will also supply power to the front axle.
With its development work in the field of eDrive technology, the BMW Group is positioning itself to field the broadest possible range of high-overall-efficiency vehicle concepts. While the BMW i3 is the ideal solution for urban and suburban mobility, future plug-in hybrid drive systems will allow fuel consumption and emissions to be steadily reduced in long-distance operation as well. In other words, it will be possible to deliver a typical BMW driving experience across a whole range of scenarios, including zero-local-emission everyday driving, long-distance trips and sporty, dynamic driving situations.
