1950 Ford Custom Deluxe Tudor Sedan
The birth of the real police cruise came when the Ford Custom Deluxe Tudor hit the market. The car was well-rounded and more modern than anything that came prior. The Tudor had a lot of power under the hood and the car was bigger than ever. The 1950 model year was the first time Ford offered their new automatic transmission, the Ford-O-Matic, as an option. This was a significant technological advancement for the automotive industry as a whole (via Hagerty).
The 1950 Ford Custom Deluxe was available with a choice of two engines, a 226-cubic inch (3.7-liter) inline-six or a more powerful 239-cubic inch (3.9-liter) flathead V8, the latter of which police departments chose to work with. The car was ultimately a hit both with the law enforcement industry and the automotive industry as a whole as many drivers enjoyed this car.
