To improve aerodynamics a rear wing was developed in conjunction with large rear window lip. The rear wing was made horizontal. Tuft testing showed attached flow to rear wing. This shape was chosen with an eye toward utility. The trunk is fully accessible. It was made with foam insulation material and covered with carbon fiber composite. The front of the car used to have a curved grill cover. It got removed along side the road during the heat of summer.
