The Turicum was a Swiss automobile manufactured from 1904 to 1906 in Zürich and from 1907 to 1912 in Uster. The car's name Turicum is the Latin name of Zürich. The first car made by Martin Fischer was a small single-seater go-kart like vehicle. The car was 140 cm (55 in) long, with pedal-operated steering and powered by a motorcycle engine. The car had a chain drive, while a second prototype had a friction drive. The friction drive consisted of a flat steel disc coupled to the engine that drove a small, leather-covered wheel running at right angles to its surface. The small wheel could be moved across the surface of the large disc, giving a variable gear ratio. The cars attracted little public interest. Swiss industrialist Jakob Heusser was involved in the venture.

The Yaxa was a Swiss automobile produced from 1912 until 1914. Its name was a phonetic rendering of the phrase Y a que ça ("It's the only one there is"). Of Genevan manufacture, the car was built by Charles Bahni, an early collaborator of Charles-Edouard Henriod. The Yaxa was a 1692 cc light car which used a four-cylinder Zedel engine; among its other touches were central gear and brake levers. Baehni drove a Yaxa to victory in the 1913 Coupe de la Gruyère; nevertheless, the marque folded a year later.

The Ajax was a Swiss automobile built from 1906 to 1910.
