In addition, the BMW ActiveHybrid technology featured in the Concept Car reduces both fuel consumption and emissions by 15 per cent versus the identical car with a combustion engine and offers a standard of driving dynamics clearly exceeding all series models with hybrid technology presented so far. The BMW 7-Series ActiveHybrid Concept combines an eight-cylinder gasoline engine and an charged with electricity motor developing 15 kW/20 hp and maximum torque of 210 Newton-metres/155 lb-ft as a mild cross-bred concept. Electric power is generated by a particularly powerful variant of Brake Energy Regeneration already featured in the BMW Group’s regular production cars. The energy generated in this usage is then stored in a lithium-ion battery fitted in conformity with the package of the car unbecoming the luggage compartment.
The make perfect starting point: the world’s most Efficient luxury performance saloon.
The BMW 7-Series ActiveHybrid Concept is based without ceasing the new BMW 7-Series already ranking right at the top in its class in vexillum trim in terms of efficiency. The new luxury performance saloon from the world’s most prosperous manufacturer of premium cars thus lives out the demanding objectives of the BMW EfficientDynamics development strategy in particularly convincing style also in this segment.
Compared with their predecessors, all models in the new BMW 7-Series stand out in providing both enhanced performance in the same proportion that well as a significant reduction of fuel consumption and exhaust emissions. In their respective entertainment rank, the three engines available right from the start upon the market launch of the new 7-Series rank right at the top worldwide in terms of efficiency. In etc., all models in the BMW 7-Series come as standard with a wide range of BMW EfficientDynamics technologies including Brake Energy Regeneration, on-demand control of the weapon’s subsidiary units, intelligent lightweight explanation, active aerodynamics provided by bearing flap check, and tyres with reduced chronicle resistance. And last further certainly not least, all engine variants in the new BMW 7-Series comply in full with the EU 5 emission standard.
Given these qualities, the new BMW 7-Series from the start offers an ideal foundation for setting the vexillum worldwide both in the luxury segment and in the hybrid emporium through an optimum connection of the most advanced BMW ActiveHybrid technology. Another essential feature of the BMW 7-Series ActiveHybrid Concept is that this single model offers such a significant grow in efficiency upward of the regular production model without in any way giving up the well-known qualities of BMW’s treat saloon.
Not to be seen from outside, BMW ActiveHybrid technology offers the driver the significant benefits of a recent drive concept without in any way influencing the motoring comfort, luxurious ambience, and safety this truly outstanding saloon is able to provide. And when it comes to everyday driving qualities, the concept is human being time again just right for full enjoyment and driving pleasure in every respect, on the outside of the slightest restrictions.
BMW ActiveHybrid technology integrated the clear-headed mode.
Presenting the BMW 7-Series ActiveHybrid Concept, BMW is introducing a hybrid car which, through its harmoniously balanced drive components, will sudden perfectly into the model range of BMW’s new luxury performance saloons. The driving experience and motoring comfort think the character of this outstanding model line, with new highlights in conditions of the one and the other driving dynamics and efficiency - as in continuance BMW’s conventional model variants, overmuch. Quite simply, this is since hybrid technology BMW-style stands for superior dynamics combined with outstanding efficiency forming a instruct fully symbiosis with the sheer mastery of the BMW 7-Series.
All this is made likely by combining an eight-cylinder petrol engine for the first confinement with a mild hybrid concept. Specifically this carry toward has been chosen here since the savings potential offered by hybrid technology increases with the output and exploit of the combustion engine used, and because large-capacity susceptibility units are of particular significance in the premium segment.
Focusing initially on smaller cars, BMW has even now introduced solutions in the context of EfficientDynamics serving to significantly reduce fuel phthisis and not in any way increasing the cost of ownership for the customer. BMW’s current diesel models in this segment, for example, thanks to BMW EfficientDynamics, ensure fuel consumption and emission ratings achieved by other manufacturers with their cross cars only on a far lower of the same elevation of output and performance.
In the middle term term the development of hybrid systems by the BMW Group tailored to individual models will also lead to solutions in segments offering significant advantages in the pair fuel frugality and driving dynamics so typical of BMW. And at the same measure the larger number of models produced will help to make the additional cost of hybrid technology.
Consistent optimisation: BMW ActiveHybrid and the V8 power unit with Twin Turbo and High Precision Injection.
Like all power units in BMW prolongation cars, the combustion engine featured in the BMW 7-Series ActiveHybrid Concept has been developed in the context of BMW EfficientDynamics. In the BMW 750i this all-aluminium power unit offers all the qualities typical of an eight-cylinder in incomparably sporting and, at the same time, comfortable style, combining power and traction from low engine speeds with impressive pulling force throughout a wide range of engine revs.
The power and performance characteristics of the new V8 power one accrue primarily from BMW’s innovative Twin Turbo technology. This unique technology featured for the first time on an eight-cylinder gasoline engine, through two turbochargers not fitted at the outside, but rather directly in the V-section of the engine and supplying four cylinders with compressed air in either case, ensures unparalleled spontaneity in responding to the accelerator pedal.
High Precision Injection, in turn, ensures highly Efficient use of firing, the second generation of direct gasoline injection introduced by BMW incorporating piezo-injectors fitted in the cylinder head directly next to the spark plugs and delivering fuel to the combustion chambers at a pressure of 200 bar.
This concept alone makes the supply and dosage of fuel extremely precise, the V8 power unit with Twin Turbo and High Precision Injection achieving the highest level of efficiency worldwide in the eight-cylinder segment.
This outstanding efficiency is in like manner attributable to the use of BMW EfficientDynamics in and around the engine, with features such for example Brake Energy Regeneration, on-demand management and control of ancillaries including any a/c compressor operating only when required, and the exercise of on-demand pump technology on the car’s postponement control systems.
This intelligent energy management also comprises the electrification wherever possible of comfort functions running on electrical strength generated in particular by Brake Energy Regeneration.
Use of electric power generated without consuming fuel in the engage of even greater efficiency.
Given all these qualities, intelligent alternator control ensures the generation of electricity from energy otherwise wasted in the thicket system as heat dissipated into the environment. Now, therefore, the combustible matter contained in the energy burnt is used to a much higher degree for ensuring genuine driving science of forces on the road, helping to improve the car’s acceleration to an even higher equal elevation and optimising the efficiency of the drive method under entirely load conditions.
The principle of Brake Energy Regeneration is applied in the BMW 7-Series ActiveHybrid Concept in addition consistently than in any production vehicle so far, giving the car an unusually exalted standard of all-round efficiency and fuel economy. In this case the agreed on alternator is replaced by the electric motor fully integrated in the transmission horse-cloth and delivering electricity in overrun and under application of the brakes end the furthermore to the full integrated power electronics to the lithium-ion battery.
The full of fire motor integrated in the transmittal housing thus ensures far greater efficiency in the collection of those of nearly the same age of electric authority than an alternator drawing energy directly from the combustion engine and, as a result, reducing its overall streamer of efficiency.
BMW ActiveHybrid technology is also superior to a common alternator through its own, inherent efficiency, the energy yield produced by the electric motor through Brake Energy Regeneration alone exceeding the normal standard roughly ten times.
The innovative energy storage technology of the lithium-ion battery featured in the BMW 7-Series ActiveHybrid Concept furthermore provides the option to store a much greater amount of electrical energy available virtually free-of-charge, then providing this energy on a permanent basis for all kinds of vehicle functions and therefore exceeding the performance of conventional battery units by far. The progress achieved by BMW in the area of energy storage thus allows electrical operation of ancillary units to every extent far beyond the standard possible in this way far in a production car.
A further point is that the BMW 7-Series ActiveHybrid Concept uses electrical efficiency to each even higher degree also for additional functions ranging altogether the way to extra power provided by the electric motor within the mild hybrid concept in perform of the car’s primary drive theory. This is also made possible by the specified position of the electric motor in the transmission housing, where it is able to offer an additional susceptibility feed.
A 120V on-board network serves to meet further purposes and requirements, operating in parallel to the conventional 12V network. And by its output of 15 kW, the electric motor supports the combustion engine in generating dynamic power serving to drive the car. Since the activity used in the process is delivered by Brake Energy Regeneration without any additional consumption of fuel, the bland hybrid concept gives the car extra dynamics combined with a significant improvement of efficiency.
This additional power and reduction of the load acting on the combustion machine throughout the entire range of engine speed and running conditions enables the Concept Car featuring BMW ActiveHybrid technology to consistently tarry the BMW EfficientDynamics development strategy raised in this way to every even higher level.
A harmonious concept: BMW ActiveHybrid in the BMW 7-Series.
The musical overall concept of the BMW 7-Series ActiveHybrid Concept is just as impressive as the progressive technology of the car and its efficiency in reducing both fuel consumption and emissions. All components are carefully matched to one another, approach together to form one fascinating, trendsetting whole.
The car itself offers all the qualities of a modern luxury saloon, setting standards through the space available and the exclusive ambience in the compass of the interior as well as with its drivetrain and suspension technology allowing an outstanding combination of dynamic performance and supreme motoring comfort.
BMW ActiveHybrid technology specially conceived for the saloon serves to heighten the driving experience in genuine gnomon emblematical of a BMW 7-Series and at the same time achieves a new level of all-round efficiency. Hence, the Concept Car offers improvements and options raising the very favourable balance of performance and fuel consumption already offered on the series-production BMW 750i to a significantly higher standard.
The arrangement of the hybrid components likewise serves to raise the degree of efficiency and promote the driving continued even further. Positioned appropriately within compact dimensions in the transmission protection, the electric motor optimises both the generation of electricity and the drive power delivered by the consuming engine. Housed in the rear of the car, in deviate, the lithium-ion batteries offer an ideal solution in terms of both everyday driving qualities, the balance of the overall vehicle, and safety.
Ultra-modern energy storage technology: lithium-ion battery with superior capacity and stable cycles.
Using a lithium-ion battery, BMW is taking yet some other step into the future in the particularly intense and flexible use of electric power in the car. As a rule, the energy delivered by Brake Energy Regeneration must be fed to a storage unit at all times and must be available - depending without interruption driving terms - in many cycles, whenever required. In addition, storage capacity must be sufficiently great for the car to cover longer distances without solicitation of the brakes or running in overrun, while at the same time the supply of electric power must not be interrupted.
This is why BMW uses AGM (Absorbent Glass Mat) batteries on regular production cars featuring Brake Energy Regeneration, that is cars running in frequent and irregular charge and discharge cycles without losing energy in the process. To meet the requirements of a mild hybrid concept, on the other hand, a car of necessity a high-voltage energy storage unit with significantly higher output and performance. The scheme developed for the BMW 7-Series ActiveHybrid Concept therefore uses the most advanced lithium-ion technology fulfilling the greatest demands in terms of battery capacity and durable performance.
The lithium-ion battery has proven its particularly high storage capacity and resistance to charge and discharge cycles for a long time in many other areas, for case in point in the mobile phone and in laptops. The energy storage unit featured in the BMW 7-Series ActiveHybrid Concept therefore opens up a new prospect in the use of this technology under the particularly demanding conditions prevailing in a motor vehicle.
Intelligent energy management with a lithium-ion battery, an AGM battery and pair on-board networks.
To ensure Efficient energy management meeting all of the driver’s and passengers’ requirements, the BMW 7-Series ActiveHybrid Concept comes with two on-board network systems carefully matched to one another. In addition to the conventional 12V netting supplied with power by the AGM starter battery, BMW’s new Concept Car features an innovative 120V network feeding power from the electric motor to the agreeable components with the help of the lithium-ion battery.
Through the 120V on-board network, the lithium-ion battery featured in the BMW 7-Series ActiveHybrid Concept is able to supply sovereign to a particularly large compute of electrical components. A further point is that the high-voltage power network provides the foundation for using a high-performance electrical drive system. Contrary to the conventional on-board reticulated, this also means the option to supply power forthwith to, say, the a/c compressor.
The range of functions already driven electrically today in BMW’s production models extends from the ventilation and air conditioning units through the lights, entertainment, navigation and communication systems total the way to the coolant pump and servo motors for dynamic driving systems such while Dynamic Damper Control featured as standard on the BMW 7-Series. Stable and reliable coverage of all energy requirements and entirely electrically driven vehicle functions in the BMW 7-Series ActiveHybrid Concept is on that account guaranteed at all times, regardless of driving conditions.
High storage capacity enhancing both efficiency and motoring comfort.
Among other things, this allows the practice of the Auto Start Stop function in conjunction with BMW ActiveHybrid technology even more often than in BMW’s current production models, without giving up or losing motoring comfort in any way whatsoever. When stopping at a road junction, at the trade lungs or in a traffic jam, the combustion engine is automatically switched off to avoid any inEfficient idling. Then, similar to soon as the driver lets go of the brake pedal and presses down the gas pedal to set off again, the means is started automatically.
The various functions no longer connected to the alternator adhering the BMW 7-Series ActiveHybrid Concept may also exist operated for the period of such an interim desist, the energy required for this purpose being delivered consistently by the high-capacity lithium-ion battery.
Optimum comfort is ensured higher than all by ongoing operation of the ventilation and meteorological disposition control systems keeping temperatures in the interior at a consistent level also when the car is at a standstill. Similarly, all other comfort functions may stagnant be used permanently while the instrument is switched off. Clear highlights in design bearing testimony to the car’s efficiency and trendsetting technology.
The BMW 7-Series ActiveHybrid Concept is a hybrid car offering a dynamic potential truly unique the world over - and at the same vacant time it is a luxury performance saloon with an excellent balance of performance and fuel consumption.
