This Dutch start-up called Lightyear has developed an electric and solar sedan capable of 710 km of autonomy!
What if you never charge your electric car? This is what promises the Lightyear One , an electric and solar sedan developed by the start-up of the same name in the Netherlands. The idea is simple: a 60 kWh battery (barely bigger than that of a Renault Zoé ), a very efficient design, and solar panels on the roof. After four years of development, Lightyear conducted the first tests of its sedan on the track, with good news on arrival: 710 km of range in one charge!
Efficiency at the heart of the concept
The figure is impressive when we know that the Renault Zoe , with its 52 kWh battery, is officially capable of 395 km of range according to the WLTP cycle . This is more than 300 km less than for the Lightyear One, which is also a large sedan ! So obviously, under this large number are hidden a few small lines. The most important is that these 710 km were covered at a steady pace of 85 km / h , which is ideal for the efficiency of electric motors. We are therefore far from WLTP certification.
Nevertheless, the electricity consumption figure is impressive: 8.5 kWh / 100 km , against around 15 kWh / 100 km for a Zoe .
72 km per day thanks to solar panels
In contrast, Lightyear is getting closer to its original promise to hardly ever have to charge your electric car . Thanks to the photovoltaic panels placed on the body, the Lightyear One can recharge approximately 72 km of range in one day if the weather is good.
In practice, the majority of home-work journeys could therefore be made without going through a terminal, or without having to have a private car park with a charging point . Convenient for those who live in the city, therefore. It remains to be seen how this figure of 72 km gained in one day evolves when the sky is overcast, in winter, and the car is parked in the shade.
Only 946 units of the Lightyear One will be sold in 2022. And if the start-up does not announce a price, it has previously forecast a price of around 149,000 € when the car is presented in 2019. But the company aims then to reach a larger public from 2023 .
