The world's most serial car was Lightyear 0, an electric car with solar panels

Lightyear from the Netherlands is able to remember not only the willingness to release an electric vehicle with an extensive solar panel on the surfaces of the body, which is able to add up to 70 km of air travel on a sunny day, but also the orientation to reduce aerodynamic resistance. After undergoing certification tests, the debut "0" of the label showed an aerodynamic resistance coefficient of 0.175 less than any of the serially produced cars.

Note that during the design phase, Lightyear engineers had the task of keeping this coefficient within 0.19, so that the plan had actually been exceeded. According to Electric, a recent round of tests showed that an electric car with solar panels on the body surfaces had an aerodynamic resistance coefficient of not more than 0.175. It was noteworthy that the previous record of 0.19 belonged to an EV1 vehicle of the American company GM, which it had tried to release in the 1990s. It had a rather controversial appearance, but the creators of Lightyear had succeeded in surpassing the achievements of the United States market only with a predictable compromise in design in the form of an extended backweight, which is also characteristic of another "reordsman", Mercedes-Benz VISION EQX, but the latter remains in prototype status.

The German autogiant also reported that it had succeeded in reducing the coefficient of aerodynamic resistance to 0.17, as a result of the VISION EQXX prototype, with a traction battery capacity of less than 100 kWh, demonstrated the ability to cross without charging to 1,200 km. Lightyear 0 in this field is more prosaic, according to developers. A thousand kilometres without charging can be overcome if it is stretched for several days, making a daily journey to work and back on the streets of Amsterdam in summer not more than 50 km, when the traction battery is regularly charged from solar panels. By moving on the highway at an average speed of 110 km/h, Lightyear 0 will drain the charge of the traction battery through 560 km and the WLTP schedule does not exceed 625 km.

In other words, the capacity of the traction battery of this electric vehicle is limited to only 60 kWh, so for such an indicator, the performance of the reserve is very good. In addition to good aerodynamics, the electric vehicle ' s cost-effectiveness is also characterized by modest dynamic characteristics: the vehicle ' s speed of 100 km/h takes 10 seconds and its maximum speed is limited to 160 km/h. The battery can also be charged from a domestic power supply with a power supply of not more than 3.7 kW, in which case the charging time will be increased by 32 km per hour. As the Lightyear 0 builders emphasize, if the rear weight of the electric vehicle is reduced by only 15 cm, this will increase the energy consumption of the power plant by 3%. The traction motors are integrated into each of the four wheels, the inverters are used in the design. The vehicle ' s mass does not exceed 1,575 kg at the expense of the active use of carbon fibre in the construction of the body panels. The rational use of thermal power is also independent.
