Chrysler Airflow is correct. In order to write about it I had to learn about it. Introduced in 1934 and only built for four years. 1937 was the last year of production. In an attempt to make it more saleable Chrysler made some changes to the body and trim to make it more acceptable to a conservative buying public. So the 1937 model looked quite a bit different--- a lot more boring---than the 1934 model. But the public still didn't like it so the plug was pulled. Innovations, at least in the American car industry, were first car to be designed using a wind tunnel, first car to use monocoque body construction, first car to use a space frame, first car to have hydraulic brakes. Power was a straight-eight, side valve engine. Initially 299 cu in and 122 hp, by the end of production the engine had been increased in displacement and power to 323 cu in and 130 hp.
