U m to be prepared for future fuel consumption and emission limits, BMW is pursuing a number of different things Technical approaches. After hybrid technology has already found its way into the 3 Series (as a prototype) and the X5 (series), it is now the turn of the new UKL platform with transversely installed front engines. BMW is showing a 2 Series Active Tourer as a test vehicle. The plug-in hybrid prototype has a three-cylinder turbo gasoline engine that drives the front wheels, a high-voltage generator in the front of the car and an electric motor whose power is transmitted to the rear wheels. This results in all-wheel drive - similar to the BMW i8, here in mirrored form. The high-voltage battery is housed below the rear bench seat to save space. The power electronics including the charging generator are located in close proximity to the electric motor above the rear axle. So there are no restrictions in the interior for the upcoming series model. Even the storage compartment under the load compartment floor should be retained.
The petrol engine produces 136 hp and 220 Nm, the high-voltage generator on the front axle contributes 15 kW and 150 Nm, the electric motor on the rear axle an additional 65 kW 165 Nm. The system output should be around 220 hp. The BMW 2 Series Active Tourer plug-in hybrid prototype should achieve a range of up to 38 kilometers in pure electric mode, and it should sprint from zero to 100 km /h in 6.5 seconds. The maximum speed is given as 205 km /h. But more important is the consumption: Here the prototype in the EU test cycle for plug-in hybrid vehicles should achieve an average consumption of around two liters per 100 kilometers and thus CO2 emissions of less than 50 g /km.
Reduce consumption and increase performance with water
What BMW has already presented in the BMW M4 MotoGP Safety Car will in future also be used when the car is charged Gasoline engines are used - direct water injection. The direct water injection is intended to lower the temperature in the combustion process and thus lead to a higher degree of efficiency. This increases performance and reduces consumption. In addition, the direct water injection enables a lower thermal load on numerous engine components and an optimized emission behavior. The new water injection will be presented in a BMW 1 Series five-door with three-cylinder turbo gasoline engine prototypes.Here, the water is not only injected into the intake manifold, but mainly directly into the combustion chamber. Refueling with water is to be largely dispensed with for the customer later. The system collects the condensed water from the air conditioning system
Fuel cell technology by 2020
Thanks to the cooperation with Toyota the development of fuel cell technology at BMW received a new boost. The goal is to continue to have tested components for a Fuel Cell Electric Vehicle (FCEV) ready by 2020. In 2006, hydrogen was still burned in a converted internal combustion engine in the BMW Hydrogen 7; in the future, the hydrogen in a fuel cell will provide power for an electric drive.
The hydrogen fuel cell drive will be presented in a prototype based on a BMW 5 Series Gran Turismo. it has a 245 hp electric motor that draws its energy from a fuel cell. The necessary hydrogen is stored in a tunnel tank between the front and rear axles. One tank of fuel should guarantee a range of over 500 km. The prototype can be refueled in less than 5 minutes.
