Off-road vehicles are not exactly a symbol of economical cars. With the new version of the X5, BMW shows that there is another way. The prototype is supported by an electric motor that recharges itself. Even the rims are particularly energy-efficient.

Apparently you can never save enough. Especially not if, as a car manufacturer, you have committed yourself to a comprehensive strategy for reducing fuel consumption called "Efficient Dynamics". At the Geneva Motor Show, BMW is showing a study based on the X5 off-road vehicle, which is said to be able to achieve significant consumption benefits with the help of hybrid modules and other components. The promised brand is: 6.5 liters per 100 kilometers.

But what technology is in the X5 will probably first be seen in the next generation of the seven-series sedan. Some of it at the start in autumn and the rest at least in two or three years. The heart of the study is a so-called mild hybrid drive, which the Bavarians are developing in close harmony with Mercedes. As usual, hybrid stands for the combination of combustion engine and electric motor and “mild” for the gentle support that the electric car is supposed to provide. In contrast to the so-called “Active Hybrid”, the electric motor only plays the role of a booster here, which starts the motor again after it has automatically stopped and helps it to accelerate with 210 Newton meters of torque. On the other hand, the engine with just over 20 HP is too weak for purely electric operation even on short distances or in traffic jams.

The electric motor produces its own energy: when idling or when braking, it acts as a generator and stores the electricity in a lithium-ion battery that BMW has installed under the trunk floor, where it is clearly visible. But even when all the engines are off, the power plant does not have a break. For this purpose, BMW has converted the roof into a solar field that also feeds the battery. Or the ventilation, a cool box or the charging station of the mobile phone is supplied when the vehicle is stationary.

The electric drive integrated in the gearbox housing is combined with the latest generation of the two-liter diesel, the performance of which the Bavarians have once again increased. In the BMW 1 Series you can already feel the effect of this powerhouse, which instead of the previous 177 hp now has 204 on the credit side. Thanks to a pulling power of an impressive 400 Newton meters, which is already available for 2000 tours, there is nothing to complain about in terms of temperament.

When they work together, the electric motor and diesel are a strong team: a sprint value of 8.9 seconds for the sprint up to 100 km / h shows that saving works without having to forego fun. With the 235 hp six-cylinder, the currently best-selling X5, the 3.0d model, takes six tenths longer. And where the most frugal production model so far still swallows 8.1 liters, the saver from the future is assigned a consumption of 6.5 liters / 100 kilometers, which at the same time means only 172 grams of CO2 per kilometer. In order to reduce consumption so much, the BMW engineers not only worked on the engine, but also on the transmission. As a harbinger of the next seven, the study gets a new automatic with now eight gears.

Not only technicians, but also the designers did their part to optimize the X5 study in an environmentally friendly way. Their work also aimed primarily at increased efficiency. That’s why they not only lowered the car a little and clad the front even more streamlined, but also developed completely new rims. They look like the blade wheels of turbines and are not only used to create a beautiful appearance. Their design has been honed in the wind tunnel in such a way that, for example, one kilowatt less drive power is required at 160 km / h than with conventional rims. The bottom line is that that doesn’t make much difference. But after all, small things also count in the fight against CO2 emissions.
