The Turbo-Titan III used a pearlescent white fiberglass and steel cab combo with its styling theme extended to the chassis, which was completely concealed by molded fiberglass panels. Doors mounted just ahead of the rear wheels on both sides of the skirt provided access to dual batteries and the turbine engine when the cab was electrically tilted. Power-operated wing-type side windows with top hinges provided operator entry when the key was inserted in the door. Retractable square headlamps were mounted within functional air intakes in two banks of three lamps each. The front turn signals were retractable, with the rears operating in sequence, flashing inward. A flat exhaust stack exited through the roof.
Inside, "Astronaut Seats" with full headrests were mounted on each side of a center console. A wing-topped handle controlling the six-speed automatic transmission was mounted on the console. Full interior carpeting was included along with retractable seatbelts, air-operated windshield wipers, full tinted glass, and air conditioning/warm air heating. A four-speaker FM stereo radio and a two-way telephone were used for the first time.
The most novel feature, though, was the GM designed and engineered "dial steering system." This unit was mounted on a pedestal in front of the driver, replacing the conventional steering column and wheel. Twin dials mounted on a padded vinyl panel operated the platforms power steering. An auxiliary pump driven from the propeller shaft provided emergency usage if the main pump failed for any reason when the platform was in motion. The automatic transmission quadrant was also mounted on this panel along with the turn signals. The pedestal pivoted forward and back along with the panel for the most comfortable driving position.
