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. It led to a rethinking of the fundamental design of Chrysler's cars with a primary focus on reducing wind noise inside the passenger compartment. Both engine and passenger compartment were moved forward, giving better balance and ride. An early form of unibody construction was employed, giving them a durability advantage in comparison to body on frame construction. It continued to offer a Chrysler engine vibration isolation feature called "Floating Power" and was one of the first automobiles to offer a one piece curved windshield. Chrysler offered both the conventional Airstream models along with the Airflow models under the "Chrysler" marque but only offered the "Imperial" marque with Airflow models. The 1934 Imperial Airflow Series CV offered the Chrysler flathead straight eight with an aluminum cylinder head and overdrive manual transmission, and body style choices were a two-door coupe, four-door sedan and four-door Town Sedan on a wheelbase, and were priced at US$1,625 ($ in dollars ). The longer wheelbase Imperial Custom Airflow Series CX offered only sedan choices, to include Town Sedan and Limousine choices on a wheelbase for US$2,345 ($ in dollars ). The top level Imperial Custom Airflow Series CW offered a four-door Sedan, Limousine or Town Limousine for US$5,000 ($ in dollars ) using a wheelbase and the Straight Eight. Documented production numbers for 1934 show 2,277 Series CV, 106 Series CX and 67 Series CW were produced. Its prestige was similar to the Cadillac Series 90 limousine, Rolls-Royce Phantom III, Packard Twelve, Mercedes-Benz 770, Renault Suprastella and the Lincoln Custom. The public was put off by the unconventional styling and the "Airstream" appearance on Chryslers outsold the "Airflow" by 3 to 1. The 1935 Imperial Airflow Series C-2 and Series C-3 were carryover from resources not used for 1934 due to underwhelming sales after the appearance was panned in favor of competitors, while the conventionally styled Chrysler Airstream was better received that replaced the Chrysler Series CA and Series CB. Total production documented records show 2,598 Series C-2 coupes and sedans were manufactured, while just 125 Series C-3 rolled off the assembly line, accounting for both coupe and sedan production. The top level Series CW recorded only 32 limousines that could accommodate eight passengers, offering four different coachwork
