The Jaguar SS 100 was a British two-seater sports car built between 1935 and 1940 by SS Cars Ltd. in Coventry, England. The "100" was named after the theoretical 100 mph maximum speed of the model. Widely regarded as one of the most aesthetic Jaguar cars, it is also one of the most rare; only 198 2.5-liter units and 116 3.5-liter units were built, of which only a small part was exported. The first car bearing the Jaguar name launched in 1935, the SS Jaguar 2.5 litre Saloon, reflecting the model's combination of elegant design, power and agility. Alongside the saloon, a two-seater roadster SS Jaguar 100 launched in 1936, with an advertised top speed of 100mph. This car was also the first to carry what would become an iconic automotive symbol, the 'leaping jaguar' hood ornament.
After the Second World War the company dropped the name "SS" and the company was renamed Jaguar.
