Modifications to the chassis include a new front end with a range of suspension setup possibilities and anti-intrusion side panels as part of a push to improve safety.

The chassis also features the "halo" cockpit protection device, a wishbone-shaped frame mounted to the monocoque designed to deflect debris away from a driver's head in the case of an accident.
