Just like previous edition, the car is once again an innovative feat. RED E is a lot smaller than the previous car, this is driven by the switch to GaAs solar cells. This type of cell is usually used in the aerospace industry. Instead of 4m2 for silicon cells, only 2.64m2 of solar array can be used of the GaAs cell type. This is very noticeable in the length of the car, basically the nose from the previous car is missing. In pure size this saves about 1.5m2.All components had to get a lot smaller and placed more efficient to still be able to fit in the car. A great example for this is the wheel suspension, it is based on the suspension systems used in Formula E. Take a better look at the model of our car below made by Jan de Witt.

RED E participated in the Bridgestone World Solar Challenge in October 2019. RED E was the leader of the challenge for three days. A strong wind gust has made an end to the 2019 edition of the Bridgestone World Solar Challenge for Solar Team Twente. Shortly after the start of the fourth day, solar car Red E was blown of the track. The car hit the roadside and was not able to get back on the road. Luckily the driver was fine, but the car has been damaged, forcing the team to end their pursuit.
