Hybrid project

Hybrid vehicles in motor sport

We began our research activities in hybrid drive systems as long ago as 2000. In 2003, the first BTD hybrid prototype was successfully developed and manufactured. Since then, we have had the opportunity to participate in many hybrid projects in the automotive industry (subject to confidentiality).

An improved version of our own prototypes has demonstrated the ecological and practical advantages of a hybrid vehicle in motor sport.

BTD – experts in R&D

From 2000 to 2003, we developed a hybrid vehicle in cooperation with the University of Liege. Our hybrid 3L VW Lupo aroused international interest and has been presented at many trade fairs.


  • Reduction of environmentally harmful emissions (60 gr. CO2 / km MVEG)
  • Reduction of fuel consumption while maintaining the same level of performance
  • Elimination of exhaust gas in urban traffic

We demonstrated the practical and ecological advantages of this hybrid technology in motor racing with our further developed version in 2007. The principle: in the pit lanes and behind the safety car, the 3L VW Lupo Hybrid stores braking energy that is later converted into driving power by an electric motor. The drive system helps to save fuel during slow driving (e.g. pit stops).

Our VW Lupo Hybrid finished 15th out of 26 vehicles in the T2 class.

This was an excellent demonstration of the efficient implementation of alternative drive systems in competition engines.
