Laurent Hecquet, Managing Director of MAP, the observatory for mobility experts, is Sébastien Krebs' guest.

Together they are interested in the new Tesla battery that Elon Musk presented.

Less expensive and more environmentally friendly, it should reduce the cost of producing a kilowatt hour by 56% thanks to a few changes in its design.

The boss of Tesla promises electric cars from 25,000 euros in a few years, the same price as a thermal car.
