High school college students have built 20 electric cars for the Electrathon America Derby Race in Richland April 29.
Teams build single-person, derby-style cars and compete to see not how fast the cars go but how long they can run using limited electrical energy.
This year the Horn Rapids Kart Track in Richland will be used, rather than a temporary track in the parking lot of Columbia Basin College. The track is at 3234 Twin Bridges Road off Highway 240.
Time trials start about 9 a.m. and the race starts at 11 a.m.
Never miss a local story.
Volunteers are needed to support the race. Call Todd Blackman, 509-539-8078.
