Audi A8: It produces electricity thanks to the irregularities of the pavement

Audi has developed a system which uses the reactions of a vehicle’s wheels to movements in the road to produce electricity, which can be fed into the engine. It will lead to a reduction in energy consumption, pollution and rolling, while improving the braking. The A8 will be the first car produced by the German manufacturers to include the system on-board.

 

 

 

In the future, the Audi A8 s set to be fitted with a new system designed to generate electricity. The aim of the system is to use the vertical movements which wheels undergo when the road surface is irregular to produce up to 613 Watts. Electric motors will be connected to the shock absorbers via the suspension on the car, French magazine Le Point explains.

 

A saving of 0.2 litres of fuel per 100 kilometres

 

Usually, energy produced in this way is wasted by the regular hydraulic shock-absorbers. The new system designed by the German manufacturer promises a reduction in fuel consumption of around 0.2 litres per 100 kilometres, which corresponds to a decrease in C02 emissions of some five grams per kilometre. Audi has already been working in this field since 2015, having developed a prototype which was equipped with an eROT (electromechanical rotary damper) system.

 

 

They are now experimenting further by fitting electric suspension. The new system will first be used on the new Audi A8, which is the brand’s flagship model that is capable of generating over 450 horse power, in both diesel and petrol versions.

 

Space-saving electric shock-absorbers

 

Electric components of this kind will gradually be introduced into Audi’s other vehicles. As well as saving energy and reducing emissions, electric shock-absorbers are smaller than hydraulic ones, thus providing welcome extra space at the back of the car around the boot. Electric motors can also reduce rolling or ensure that braking is less jerky.
