The Vattenfall Solar Team unveiled their latest solar car, the Nuna11, on 8 July. The most striking feature is the unique design. The solar car is a three-wheeler with the third wheel in an unusual position and an angled solar panel. With Nuna11, the team hopes to take home the title at the Solar Challenge Morocco in the autumn. Nuna11 is full of new technical innovations. The special design of the solar car results from the daring choice of two wheels on the right and one on the left. This gives Nuna11 an novel appearance and justifies the name 'Picasso of solar cars'. More importantly, the innovative design optimises the solar car's aerodynamics.

This type of car is called a catamaran in the solar racing world. With the previous Nuna9 and NunaX models, the Vattenfall Solar Team showed how to use this to take advantage of the wind. With the special design of the Nuna11, this advantage can be combined with less rolling resistance from the three wheels. The angled solar panel is also eye-catching.

The new motor controller is a less visible, but equally important, innovation. Previously this was a purchased component, and the team had to choose between power (necessary in hilly terrain) and efficiency. Nuna11 has a controller designed in-house that combines the best of both worlds. Team member Jasper Insinger worked on it for several months, often deep into the night.

The Vattenfall Solar Team aims to participate with the Nuna11 in the Solar Challenge Morocco in October and hopes to add a first-place finish to their track record of seven golds in Australia and three golds in South Africa. That's a major challenge with so many top-ranked participants. Whether the race will actually take place depends on the developments and measures regarding the Covid pandemic.

The teams will travel around 2,500 kilometres in five stages spread over the same number of days. The route runs from the south of Morocco, passing along the Atlas Mountains and through part of the Sahara. This means the route has more height differences than in Australia. The teams will start and finish in the port city of Agadir. The team that covers the total distance in the least time wins the race.
