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. 

After World War II, Tatra found itself stranded behind the Iron Curtain.  Hans Ledwinka was accused of collaborating with the Nazis and was imprisoned from 1945-51.  The T-600 was introduced at the 1947 Prague Auto Salon.

When the centralized planned economy in the Czech Republic appointed Tatra to be the manufacturer for big automobiles, work started on the T-603.

In 1996, Tatra introduced the new T-700. It had the same layout and general body lines as the T-613. The T-700 originated one year earlier when British designer Geoff Wardle was asked by Tatra to update the original body structure.

In 1934, Tatra came out with the T-75.  It was slightly larger than the T-57, making a 4-door body possible.  The motor was also enlarged about 50%, bringing the power up to 30 HP.

The Tatra T 815- series of heavy trucks, now known as Tatra TERR No.1, are the bread-and-butter model of Tatra. Almost infinitely configurable from 4x4 to 12x12, with either air- or water-cooled engines by six manufacturers, 3 types of manual, automatic, or electronic transmissions by three manufacturers, 2 passenger, 2+ sleeper, or 8 passenger cabs, with a tipper bed, dump bed, fifth wheel, crane, fire equipment, armored, weaponized, NBC-capable – you get the idea – it’s a remarkably capable truck, and may be outfitted for almost any scenario.
