  • I like the design, detail and most of all its my car too.

  • I like that you considered the aesthetics (how it looks) as well as the performance. The smooth edges and the painted panel mount are a great look. I also noticed that you changed the angle of the solar panel and were able to improve 2 tenths of a second over a short distance. This can make a big difference when you are racing the car.

  • This is mine so I love it!

  • good car like the design

  • I really liked how much detail you put into your video. Building a solar sprint car is no easy task. You should feel very proud of yourselves for building, testing, redesigning, and running the car!

  • Nice job, Sun Runners! I enjoyed seeing all of the details that went into your car. It looked very fast!
