Recently, Lightyear, a Dutch start-up company, released a set of latest parameter information of its solar car Lightyear one: the official said that the wind resistance coefficient of the car is less than 0.2cd, and under wltp conditions, its endurance mileage is 725 km (451 miles) with energy consumption as low as 8.3kwh/100km. The car made its debut at the Goodwood speed Festival 2019 and is scheduled to start delivery in 2021. "Prototype Lightyear one vehicle under wind tunnel test" it is understood that Lightyear recently shipped its prototype solar electric vehicle Lightyear one to Turin, Italy, and tested the aerodynamic performance of several different configurations. The final measured wind resistance coefficient is less than 0.2cd. In addition, the vehicle's endurance mileage under wltp is updated to 725 km (451 miles), and its energy consumption under this condition is only 8.3kwh/100km. One's whole vehicle model is a four door vehicle with smooth body lines. A through LED light belt is designed on the front face, which improves the width in the visual effect. In front of the cabin cover, the roof and the rear compartment cover, are inlaid with photovoltaic cells that can convert electrical energy. The through LED light belt is also designed at the rear of the car, which responds to the front face. In order to reduce the wind resistance to a certain extent, the car not only uses a closed low wind resistance rim, but also adds a mask on the top half of the rear wheel. The body dimensions of the car are 5057 / 1898 / 1426mm in length, width and height respectively, but the wheelbase parameters have not been published. In terms of interior decoration, the car adopts a minimalist design style and basically has no physical buttons. The steering wheel has a flat bottom and three spoke design, adding more movement to the car. The car uses an electronic rear-view system. The traditional exterior rear-view mirror is equipped with a rear facing camera, and the display screen is located on the front door panel. In terms of power, the car will be equipped with four independently controlled motors, and the official acceleration time of 0-100km / h is 10 seconds. In terms of charging, in addition to solar energy (12km / h) charging, the vehicle can also use on-board charger (35km / h when the charging power is 3.7KW; 209km / h when the charging power is 22KW) and DC fast charging (507km / h when the charging power is 60kW). Under wltp condition, the vehicle's energy consumption is as low as 8.3kwh/100km with 725km (451 miles) of endurance, and its power battery capacity is 60kwh. At present, the car has been booked at a price of 119000 euros (928200 yuan). The first 100 cars have been booked and delivery is expected to start in 2021, officials said.
