The United States
The Zephyr was the first streamlined car which was widely accepted by customers. At that time the Zephyr represented 80% of the total sales of Lincoln. In early 1934, Chrysler had already produced a streamlined car called the “Airflow”. But it wasn’t popular because of its weird appearance. The Zephyr was equipped with a high-power V12 engine, and its front lights had been integrated into the fender board and the step boards became a natural part of the car frame. All these changes forged a streamlined profile of the car.
