Most competitors in the American Solar Challenge 2016 are now running laps in the Formula Sun Grand Prix (FSGP) at the Pittsburgh International Race Complex. I thought it would be interesting to compare the fastest lap speeds so far (from here) against selected average speeds from the World Solar Challenge 2015:
Michigan has the fastest FSGP lap, running faster than their WSC 2015 average speed. Principia and Toronto were also running faster. The other interesting point is that all the fastest cars seem to be four-wheelers.
