Photography: Action and behind-the-scenes at Sonoma Raceway

I had the fantastic opportunity to cover the 2018 Shell Eco-Challenge at Sonoma Raceway last month. The four-day event was a competition between college and high school engineering students to design, build and race the most fuel-efficient vehicle possible. The top winners of each category - electric, gasoline and hydrogen - proceeds to the big race in London later this year.
