The Speedway concept extends the limited range and speed of current electric vehicles by supporting it on long distance rides with an external linear motor. This propulsion is embedded beneath the pavement of highways. The vehicle is driven by a drifting magnetic field. Due to the transfer of the propulsion power for long range drives into the infrastructure, the vehicles can be lighter and more economical. The benefits of energy efficiency of electric cars can therefore be used on long range trips.

The contact-free operating linear motor can be installed beneath any existing road. This offers the possibility of a step by step implementation without derailing the existing system. During the ride the infrastructure is used to charge the onboard batteries of the speedway vehicles.

The difference

There are a lot of dual-mode concepts in discussion right now. Their major problem is the need of a new, exclusive infrastructure. The speedway concept uses the existing streets in the city. Only highways for long range distances will need to be upgraded. But even with this upgrade, the streets still can be used by conventional cars.
