"""For owners of all manner of clean power and high-efficiency vehicles, this is a chance to drive on world famous Mazda Raceway Laguna Seca. Electric, solar, hydrogen fuel cell, compressed air and other non-internal combustion engine cars and motorcycles will get the chance to drive the track for free*. This will include parade laps, practice lap sessions and Time Trial competition. Owners of Alternative Fuel Source and Clean Diesel vehicles can run with our conventional engine groups with the AltFuel discount. Crew, family and friends are all welcome to attend."""
While the event is a celebration of all alternative-fuel vehicles, it seems very friendly towards home-built EVs. Maybe now is a good time to get your EV track-ready and see what it can do!
The event is on July 19th at the Laguna Seca Raceway in Monterey, CA.
