The 1934 to 1936 Chrysler Imperial ushered in the 'Airflow' design. The car was marketed with the slogan "The car of tomorrow is here today." It featured eight passenger seating and again an eight-cylinder engine. This was the first car to be designed in a wind tunnel. Initial tests indicated that the standard car of the 1920s worked best in the wind-tunnel when pointed backwards with the curved rear deck facing forward. This led to a rethinking of the fundamental design of Chrysler's line of cars. The Airflow was an exceptionally modern and advanced car, and an unparalleled engineering success. Both engine and passenger compartment were moved forward, giving better balance, ride and roadability. An early form of unibody construction was employed, making them extremely strong. This was one of the first vehicles with fender skirts.
