BMW 7 Series ActiveHybrid

The BMW ActiveHybrid 7 is the first car in the world who wears a V8 petrol engine mated to a of eight-speed automatic transmission and also to an electric motor. Thanks to the combination of an eight-cylinder direct-injection turbo petrol with a three-phase synchronous electric motor, the BMW ActiveHybrid 7 has a total power of 465 hp and maximum torque of 700 Nm. The transmission of force is in charge of a box of eight-speed automatic transmission. The electric motor, very compact, is mounted between the combustion engine and the converter of the automatic gearbox and get their energy in a lithium ion battery.

The BMW ActiveHybrid 7 is capable of accelerating from 0 to 100 km / h in just 4.9 seconds and reaches a top speed of 250 km / h (electronically limited). However, average consumption according to EU test cycle is only 9.4 liters per 100 kilometers and also the value of CO2 is a modest 219 grams per kilometer.

Intelligent Solutions
The BMW ActiveHybrid 7 is the first BMW with an automatic gearbox featuring Auto Start Stop function, which prevents the combustion engine idling car to stop at intersections or congested traffic. It is also the first time the air conditioning and ventilation system can continue operating while the engine is off, as both feed systems, like the electric motor via the onboard network of 120 volts, the lithium ion battery. This energy management system reduces the first time in a luxury car, the temperature in the cockpit through a stationary climate. Thus, within a temperature less prevalent and more enjoyable, before starting the engine.

Several specific indicators, which are in the dashboard and the screen display control, report on the efficiency and operating status of hybrid system components This hybrid car BMW 7 Series is distinguished from others by being fitted with alloy wheels with 19 inch turbine type design of ten spokes, aerodynamically optimized, and for putting the model name on the trunk lid, C behind the upright rear side window moldings and beautifying of the doorways. In addition, the BMW ActiveHybrid 7 has a Bluewater metallic color exclusive to this model.


Like the other models already known from the BMW 7 Series, including the BMW ActiveHybrid 7 launches with two body variants (short wheelbase and long). The long wheelbase version has a wheelbase 14 centimeters higher, to fully benefit passengers occupying the rear seats. The two models can be equipped with numerous optional equipment and accessories available for all models of BMW 7 Series.

Energy efficiency
The BMW ActiveHybrid 7 comes as standard, like other BMW models, a system to recover energy lost in braking. In the case of BMW ActiveHybrid 7, also takes advantage of the deceleration phase, but the braking phase is used more intensively in order to generate electricity. The electric motor, mounted between the combustion engine and gearbox, assumes the function of an alternator. When the driver removes his foot from the accelerator, the electric motor changes its leading role in the function of a generator. Already at this stage becomes deceleration energy into electricity. Stepping on the brake pedal, the alternator takes additionally a function of retardation, which results in greater power generation. In the BMW ActiveHybrid 7, resilience is eight times higher than in the case of a BMW model system for recovering braking energy, equipped only with a combustion engine.

En el BMW In the BMW ActiveHybrid 7, resilience is eight times higher than in the case of a BMW model system for recovering braking energy, equipped only with a combustion engine.

If necessary decelerate the car shortly, is used only when braking the electric motor. Only if the steps on the brake pedal harder, is also activated mechanical braking system. The proper coordination of the effect of electrical and mechanical braking is provided by the system control unit DSC (Dynamic Stability Control). This system does not affect the strength of the brake. The change of the electric braking mode of mechanical braking occurs without any delay, so that the driver is unaware of it.

When accelerating, the energy from the lithium-ion battery is transmitted to the onboard network. Thus, the combustion engine does not have to transform part of the energy contained in the fuel directly into electrical energy, which means that most of its power can be harnessed to improve the dynamic qualities of the car. Therefore, the car has a greater ability to accelerate. Electrical energy, meanwhile, is generated during phases of deceleration or braking, so that there is no additional fuel consumption.

Versatile energy management
The current, generated without increasing power consumption during phases of deceleration and braking of the BMW ActiveHybrid 7, is fed to the two networks on board, as needed. The BMW ActiveHybrid 7 has a network of conventional onboard 12-volt battery powered AGM (absorbent glass matt), and also has a high-voltage battery with lithium ion technology, whose voltage is 120 volts . This battery feeds the electric motor when it assumes its role as an engine of support or alternatively, when dealing with starting the combustion engine.

Also the air conditioning compressor for the BMW ActiveHybrid is included in the network of 120 volts. All other electrical functions of the car receives current network of 12 volts.

The two networks on board are bound together by a voltage converter. Thus, energy management is very versatile and besides, it makes all car electrical components operate using power generated without causing additional fuel consumption. The 12 volt battery supplies power from high voltage network. And this battery can support the high voltage grid when necessary, for example when operating the combustion engine cold.

Lithium Ion Battery
With lithium-ion battery, BMW has taken an important step on the road that leads to a strong and versatile use of electric current in the car. The energy generated by the system of recovery of braking energy is fed at any time, according to driving conditions in various phases, to a battery. Thus, this energy is available when needed. In addition, the storage capacity must be high, so that energy is also available on long journeys when no deceleration or braking phase, without causing a shortage in the system of electricity supply.

AGM batteries, used in conventional models with energy recovery system from braking, are distinguished by not losing their level of performance although the charge and discharge cycles are frequent and irregular. But the criteria applied in the Mild-Hybrid concept are stricter. Therefore, it uses a high voltage battery much higher performance, so that the electric motor has the power capacity required to meet its propulsive function. The system developed for the BMW ActiveHybrid 7 is based on the lithium ion technology more modern, capable of meeting the most stringent criteria in relation to electric charge and durable performance.

This battery accumulates energy equivalent to 400 watt hours. It comprises 35 cells and has an integrated control unit which constantly monitors the state of charge, thus ensuring the smooth operation of the system in diverse driving conditions, and also in highly variable thermal conditions.

The lithium ion battery measures 37 cm long by 22 cm wide x 32 cm high and weighs 27 kilograms. This battery is in a box of special steel, highly resistant, and is mounted in the trunk, between the wheel arches. In that place is optimally protected and also contributes to a balanced distribution of weight in the car. The battery occupies much space as additional compressor air conditioning system for the rear of the carrier, offered in conventional models of the BMW 7 Series. Therefore, the trunk of 460 liters of BMW ActiveHybrid 7 also offers enough space for four golf bags of 46 inches.

Development and manufacturing
The hybrid components used in the BMW ActiveHybrid 7 are the result of cooperation between BMW and Daimler. The goal of this cooperation is to develop and test components for hybrid engines for the luxury car segment. In addition to the electric motor and lithium ion battery, this cooperation has allowed the development of power electronics for high voltage network of the BMW ActiveHybrid 7. However, each brand is responsible for integrating the hybrid components in their own models, considering their specific characteristics. In the case of BMW ActiveHybrid 7, this integration of BMW itself is expressed through the specific combination of an eight-cylinder engine and an electric motor. The BMW ActiveHybrid concept consists of modules, which means that the components are used for optimized vehicle concept, according to the criterion "Best of Hybrid".

The BMW ActiveHybrid 7 is manufactured at the BMW plant in Dingolfing. He also made all the other models in the BMW 7 series and also other brand models.
