Not many changes were made to the Au 1933 except that the high-end Salon trim line was added. The 1933 Autorn was one of the most affordable and reliable cars on the road.
This car is powered by a 268.6 cu-inch Lycoming engine that produces a whopping 100 horsepower and has standard freewheeling. There’s a two-speed rear differential, chrome wheels and padded seats. (The Lycoming engine plant is part of the Cord business empire.)

In 1932, the recession severely damaged the company as less than half of the cars Aurns produced were sold. The unsold 1932 models were mostly renamed the 101 and 161 series, thus accounting for a large portion of the introductory sales figures for 1933. Only 5,000 were sold.
What made this coupe stand out was its unusual roof, a retractable roof panel – the only one known to be installed. It was patented by an Ohio-born German mechanical engineer and inventor, Conrad Jobst, who also developed gradient compression garments for the medical industry.
It was a prototype that incorporated a single retractable hardtop and was mounted on an Auturn eight-cylinder salon chassis. Jo developed the idea of a hardtop and acquired this 1933 model to use for the idea.

The upper part consists of three parts: the rolling center part, the rear hinge part and the door handles on each side of the car. The central part is structured like the door of a roll-top table.
Pulling a ratchet handle onto the top of the dryer causes the top to shrink inch by inch until it is completely hidden in the top well behind the seat.
The hinged rear section is then rotated rearward into the well using the arms on each side for guidance. The arms are then removed, reinstalled and hidden in padded compartments, at which point the drier is ready for the convertible engine.
