In 1931, Tatra introduced the T-57 model, with the air-cooled, four cylinder, overhead valve engine placed in the front. The T-57 was one of Tatra’s most popular models–four series were produced. It remained in production until after World War II. The example shown here is a T-57 (series 1) and was nicknamed “Hadimrška” which means “swift little lizard.” It was produced in various body styles and concurrently with the T-97 and T-87. While the T-87 with its v-8 engine and streamlined body was Tatra’s premier offering, the T-57 was a more economical car for the masses. It lacked the top speed and braking performance (because the brakes are mechanical) of the streamlined T-87 model. Consequently, the T-57 was produced in large volume–26,540 models.
