Under the new changes, the Tesla Model S Plaid is legal on the drag strip as long as it does not breach 9.0 seconds and 150 mph, and drivers have an NHRA Level 6 license. In addition, the car should have OEM-installed brakes, chassis components, floors, firewalls, and safety equipment (airbags). The tires can be OEM or aftermarket, providing the rubber is DOT-approved.
