1934 Oldsmobile 8 Convertible Coupe 

In the 1930s through the 1990s, Oldsmobile used a two digit model designation. As originally implemented, the first digit signified the body size while the second represents the number of cylinders. Body sizes were 6, 7, 8, and 9, and 6- and 8-cylinder engines were offered. Thus, Oldsmobiles were named 66 through 98.

In 1937, Oldsmobile was a pioneer in introducing a four-speed semi-automatic transmission called the "Automatic Safety Transmission", although this accessory was actually built by Buick, which would offer it in its own cars in 1938. This transmission featured a conventional clutch pedal, which the driver pressed before selecting either "low" or "high" range. In "low", the car shifted between first and second gears. In "high", the car shifted between first, third and fourth gears.
