#TECH: With a solar roof, a car can add 1300 km of driving range per year

IN its 2022 version, the Sonata's hybrid roof allows the car to add about 3-4 miles (up to 6 km) every day with an average sun exposure of about 6 hours. Depending on the amount of sunlight, this additional mileage can total up to 1300 km throughout the year. On average, according to the South Korean manufacturer, the roof boosts the car's energy efficiency by about 7%. The presence of a solar roof also makes it possible to considerably reduce the occasions of finding oneself with a completely discharged battery.
