The Skoda of the 70s entered the market with few technical but even more aesthetic innovations. The S100 was the first Czech car where sales numbers reached seven digits, and its technical foundations lasted for a quarter of a century.

The S100 model arrived in 1969 and inherited the technical solutions of the 1000 MB, although there was progress in the braking system. The first drum brake was replaced by a disc brake produced under a more modern Dunlop license, and the S100 had two circuits instead of a single-circuit brake system. The exterior became cleaner, fewer decorations were added, due to the rear-engine design, the mask without a radiator grille and the cooling opening on the rear fender remained. At the back was a one-liter, 42-horsepower engine, which drove the rear wheels through a four-speed gearbox. For better weight distribution, extra weight was sometimes placed in the front luggage compartment. The S100 was available in more options. S100 L was available with more chrome and a four-speed windshield wiper and for those who wanted a stronger engine, there was the S110, with a 1.1-liter block that produced 52 horsepower. The most expensive version was the Skoda 110R, which was nicknamed the "Czechoslovak Porsche".
