October 1983 saw the release of the luxurious, Sigma Super Saloon. Produced as a limited edition of 500 cars and placed above the SE trim level from which it derives, it came only with the 2.6-litre in either five-speed manual or three-speed automatic. The five-speed manual fitted was of Japanese origin, rather than the BorgWarner Australia unit previously fitted to Sigmas, and the suspension received a re-tune. The Super Saloon featured two-tone metallic paint and crushed velour upholstery for the interior. Two paint and trim combinations were offered—blue upper body with silver lower body and blue interior—or dark brown/light brown exterior with a bronze interior. The Super Saloon introduced standard power steering, power windows and central locking—features that also became optional on Sigma GL, SE, and GSR trims. The central floor console was also revised to accommodate the power window and central door locking switches. Other equipment fitted to the Super Saloon included air conditioning, alloy wheels, and four-wheel disc brakes.
