In September 1978, the Corona was fully remodeled to enter the sixth generation. The most prominent changes in mechanical components were in the newly designed chassis, which featured a MacPherson strut and coil spring independent front suspension and a 4-link and Panhard rod/coil spring rear suspension. All models came with front disc brakes, and high-grade models employed 4-wheel disc brakes. Power steering was available as an option.

The initial body variations included a 4-door sedan, a 2-door hardtop, and a 5-door van. A liftback was added to this lineup in October 1978, becoming the first Corona 5-door hatchback sedan in ten years. Its gently sloping rear with a wide-opening hatch gate was appealing to some users whose hobbies required use of large equipment.
