Lightyear One solar electric vehicle sets the record for efficiency

It arrives on the European market in summer with 725 km of autonomy and already has an estimated price

Lightyear will launch on the market its electric vehicle (VE) solar One and the presentation of this slender car filled with solar panels that fill the hood, roof and the rear section in the window area is achieved with record-breaking status for energy efficiency, announcing even 725 km of autonomy.

Released this month the test done in June with the validation prototype, Lightyear One managed to make a course of more than 710 km with a single charge being this “the greatest distance achieved by an electric vehicle with 60 kWh of energy”.

“At a speed of 85 km/h, we ran for almost 9 hours straight on a single charge. even the most efficient electric cars on the market today consume around 50% more energy at this relatively low speed.”

For this Dutch-based company, it’s about taking the energy efficiency of an EV to the next level: “Lowering energy consumption per km ensures you get a lot of autonomy with a small battery.” As batteries are the most expensive of EVs, the goal is to get affordable vehicles with a long range.

PUB

With efficiency at its genesis, as the more efficient an EV is, the more autonomy it can have, the Lightyear One’s design involves not only small batteries, but also other low-weight components, such as suspension or brakes, to make the car as light as possible achieving the lowest possible rolling resistance at low speeds.

Efficiency is achieved by having a light car that achieves a lot of autonomy without needing a large battery that would increase its weight and the same principle applies to wind resistance when speeds increase with aerodynamics being also fundamental.

The replacement of the exterior mirrors by cameras, the elongated and slender shape, the placement of the motors on the wheels without a transmission system are characteristics that give this car a coefficient of drag (Cd) below 0.20.

The Lightyear One is equipped with four independently controlled electric motors and torque vectoring promising 0-100 km/h acceleration in less than 10 seconds and a consumption of 83 Wh/km.

Measuring 5,057 mm long, 1,898 mm wide and 1,426 mm high, this EV for five adult occupants has a minimum luggage capacity of 780 liters (up to 11,701 liters) and offers technological features as standard with the Apple CarPlay and Android platforms Auto and wireless updates.

Lightyear promises many kilometers and days covered on your solar One without charging at stations. Among the different charging options, the guaranteed autonomy per hour of charge is: 12 km with solar energy; 35 km with a power of 3.7 kWh in 230 v sockets; 209 km in 22 kW public pay-telephones; and 570 km on 60 kW fast chargers.

The ranges announced for the Lightyear One are: 725 km on a WLTP cycle at an average speed of 46 km/h and a temperature of 17ºC; 600 km on the highway at an average speed of 100 km/h and with a temperature of 17ºC; and 400 km on the motorway in winter at an average speed of 100 km/h with a temperature of -10°C

From measuring the profitability of solar panels to the energy consumption of the cooling system, the development of Lightyear One will continue its mission to “bring clean mobility to everyone, everywhere”.

With crash tests and WLTP cycle tests scheduled, production of a series of 946 Lightyear Ones with a unit price (before tax) of 150,000 euros will start in the first half of 2022 with the first deliveries scheduled for the summer in the markets of the European Union, Norway and Switzerland
