What production car had the first one piece curved windshield?
The 1934 Chrysler Imperial Airflow CW was a limited-production upscale version of Chrysler Corp.'s radical new Airflow design. It was the largest and heaviest car ever made by Chrysler. The car had the first single-piece curved windshield on any production car.
The formal Custom Imperial Airflows were undoubtedly the world's most luxurious motor cars. Aside from the increased interior space and superior ride provided by the Airflow's design, the Custom Imperials came with a long list of standard equipment befitting their $5,000 and up prices.     Some of the items were fold away auxiliary seats, robe rail, multiple reading lights, cigarette lighters, and an impressive, curved, one piece windshield made of safety glass. The latter an industry first.
