Solar Team Twente Unveils New Solar Car

The RED E, a.k.a. ‘The Kart’

Solar Team Twente unveiled their new solar car, the RED E. With the new car the team is aiming for a top position during the Bridgestone World Solar Challenge in Australia in October this year. Smallest and most energy efficient solar car ever ready to compete in Bridgestone World Solar Challenge.

Mammoet supports Solar Team Twente in their quest to win the World Solar Challenge. For this year’s design, the team has chosen to use GaAs (Gallium Arsenide) solar cells. These solar cells are mainly used in space travel, because of their high energy efficiency – higher light absorption combined with a higher energy output. As a result, only 2.64 m2 of solar panel surface is needed, instead of 4 m2, for the necessary power output. This choice has enabled the team to design a car that is much smaller than before – in effect it is 1.5 meters shorter than the previous version of the solar car, earning the smallest solar car in Solar Team Twente’s history the nickname, “The Kart”.

Frances van Elburg, Marketing and PR manager of Solar Team Twente explains: “The design team has put every effort in ensuring the aerodynamics of the car is optimized, while at the same time maximizing energy output. As a result, the resistance of the car is about the same as a soda can. When the car drives at a speed of 80 kilometers per hour (appr. 50 miles per hour), it consumes as much energy as a sandwich press.”

The Bridgestone World Solar Challenge 2019 will start on October 13, 2019. The competing teams will traverse Australia in a 3,000 kilometer race, from Darwin to Adelaide.

Theo Kroese, Global Director Marketing & Communication at Mammoet: “We congratulate Solar Team Twente on accomplishing this important milestone. The role of solar power in the global energy mix is rapidly increasing, which is why Mammoet is happy to support the team. We are proud of their progress and of course we hope that their efforts will lead to a victory in October. We wish them good luck!”
