Team Eindhoven's Stella Vie car achieved 2.5 times the efficiency of runner-up Bochum, and was awarded the full 80 points for efficiency. The team have carried an average of 3.4 people over the 3021 km, using 45.7 kWh of external energy. By comparison, a Tesla Model S85 (85 kWh battery) has a practical range of about 400 km. Stella Vie's top speed is . After receiving the highest practicality score on the final day of the WSC event as well, the Dutch clinched the title for a hattrick. Stella Era Stella Era, Solar Team Eindhoven's fourth-generation solar electric car, purpose-built for the 15th edition of the Bridgestone World Solar Challenge in 2019, performed as well as its predecessors. After the hattrick in 2017, Stella Era delivered a fourth consecutive Cruiser Class championship, and were called "in a class of their own". To win the 2019 Cruiser Cup, solar cars had to complete the journey from Darwin to Adelaide within set time windows, to prove their viability as daily drivers. Out of 13 competitors – twice the number as before – only three finished all legs within the time frames. Stella was dominating with 111.7 points, versus Australia’s Sunswift with 56.1, and Hong Kong’s Team IVE Engineering Solar Car Team with 44.2 points. The Cruiser Class designs were judged by an expert panel, to evaluate the market potential of each solar electric car. Twelve adjudicators included industry leaders from Tesla, Suntrix and Prohelion, past BWSC and faculty alumni, international solar challenge organizers from Chile, South Africa, and America, and media representatives. The assessment covered characteristics including innovation, environmental impact, ease of access, occupant comfort, control ergonomics, features, styling and overall desirability. The Eindhoven car continued its dominance, winning the practicality rating with a score of 93.1 points, before Lodz with 82.4, and Cambridge University Eco Racing with 79.9 points. The car built by the team focused on the practical uses of a car, being more than just a mode of transport. It features autonomous driving systems that detect when the car's solar panels are parked in the shade, on a parking lot, and it will automatically move out of the shade, and into the Sun. Moreover, Stella Era
