1936 Chrysler Airflow   The Airflow lead the way in terms of aerodynamics (or "streamlining" as it was then called), it was the first mass-market car in the world to use the "modern" architecture that has now become standard.   The passengers comfortably rode in a roomy interior between the axles. Power was supplied to the rear wheels by a front mounted in-line eight engine, pushing the Airflow into higher than normal speeds while maintaining good economy. The Airflow had many revolutionary ideas, like the placement of a portion of the engine ahead of the front axle, which allowed moving the passenger compartment forward.
