Lightyear one, a solar car launched in June last year by Lightyear, the Dutch "new power of car making", has attracted more attention recently, because foreign media Elek published an experience article about Lightyear one. The car can run 450 miles (724 kilometers) without sunlight with a 60 kilowatt hour battery pack, the article said. Judging from netizens' comments, this data is quite "incredible". According to the data previously released by Lightyear, the drag coefficient of the car is less than 0.2cd, and under the wltp test condition, the endurance mileage can reach 450 miles, while the energy consumption is only 8.3kwh/100km, and the car is scheduled to start delivery in 2021. The car has been booked at a price of 119000 euros (928200 yuan). Lightyear one is a four door vehicle with smooth body lines and sci-fi style. In terms of power, the Lightyear one is equipped with four independently controlled motors, with a 100km acceleration time of 10s and a 60kwh battery pack. Due to its low energy consumption, the vehicle has a range of about 450 miles under wltp conditions. In terms of charging, the roof and bonnet of Lightyear one are equipped with 5 square meters of solar panels, which can charge the battery of one. It is estimated that the maximum driving distance for charging is 12 kilometers per hour. According to foreign media, these solar cells of Lightyear one are more efficient than traditional batteries. The former provides 20% more energy than traditional batteries, and is protected by safety glass to avoid damage. If the average person works for 8 hours, let one park in the outdoor parking lot to absorb the sunshine on a clear day, and the converted energy can increase the driving distance of the car by about 100 kilometers. With an electric vehicle that can run 725km under wltp and equipped with solar panels, the one-time full charge range of Lightyear one will greatly exceed the 595km driving limit of Tesla, the industry leader. However, Tesla has an advantage over Lightyear one in running 12km with solar energy storage at a distance of about 50km per hour. Lightyear said that in addition to solar charging, it can also be charged through chargers, one for the car charger (the charging power is 22KW, which can provide 209km of endurance in one hour) and the other for the DC fast charging (the charging power is 60kW, which can provide 507km of endurance in one hour). Although it seems ideal, there are still many doubts about the practical significance of Lightyear one. Strictly speaking, the solar car is more like an electric vehicle, but the extender is not solar panels and solar rechargeable batteries. Although in theory, it is very environmental friendly and energy-saving, but with the current technology, the efficiency of solar power generation is not high, and in actual use, it is faced with many natural conditions, so the car experience is a bit "troublesome". In addition, according to foreign media, the starting price of Lightyear one is about twice that of model S. how many people are willing to spend so much money to experience such a car?
