Per a release from Scania, the company recently partnered with Uppsala University and the energy company Midsummer to develop a 560-horsepower plug-in hybrid semi-truck prototype whose 60-foot-long trailer is wrapped in 100 square meters of solar panels. According to CleanTechnica, the additional solar powered boost could supply the truck with an additional annual driving range of up to 5,000 kilometers in Sweden—a promising figure, given the prototype’s location.
