The SEB has released the ruleset for a new provisional class - Electric Vehicles Experimental (EVX). This ruleset draws from Street and Street Touring with the intention of choosing common-sense allowances to balance streetability and autocross preparation. Example: In many cases cars come from the factory with narrow wheels to improve real-world range. Wider wheels/tires will diminish range slightly but still work well for street use while improving autocross performance. This new provisional class will be eligible for regional and Tire Rack National events (excluding Solo Nationals) beginning with the 2021 Tire Rack SCCA Chicago Champ Tour event on May 21-23.
