“We believe in democratizing 22 electric cars”
[GKN]
In the beginning was the frog. In 1780, when Beethoven was just a young boy of ten years old, the Italian biologist Luigi Galvani was working on biophysical experiments with frogs’ legs in Bologna. Using test equipment consisting of a variety of different metal wires and a simple high-voltage electric machine, he was able to make the legs of the dead frog twitch when the machine produced a spark. This was movement with the aid of electricity – electric mobility in other words. A start had been made. In some respects, the development of electric mobility is still in its infancy, because designing a fail-safe, affordable electric powertrain presents new challenges. This is due to the fact that we have much less experience of real-life situations on the roads and of test methodologies than we do in the case of vehicles with combustion engines. We need a method of virtually transforming existing measurements made when customers are driving so that they can be used in newly designed electric cars with one or two drive axles. There is hidden potential in the two drive axles if we can succeed in making innovative modifications to conventional all-wheel drive systems that will bring about considerable improvements, including a significant increase in their overall efficiency and a reduction in CO2 emissions. These improvements could in part be transferred to other types of transmissions of the kind found in hybrid and electric cars, which would represent another step toward efficient electric mobility.

This is the direction being taken by Ford, which plans to bring 14 electrified models onto the European market this year, increasing to 18 by the end of 2021. Ford is expecting impressive sales figures following the recent launch of the Kuga plug-in hybrid. Matthias Tonn and Michael Geaney from Ford’s development division discuss the technical features of the new Kuga in the ATZ interview. And we find out why a hybrid drive is not the answer for every car. Frank Jung
