For Peugeot, a new naming scheme was introduced when the Type 190 was replaced by Peugeot 201.[3] The 201 was the first Peugeot to carry a name comprising three numerals with a central zero, a naming scheme continued with the 301 and 401. Peugeot took effective steps to protect all such automobile names, to the discomfiture of Porsche in the 1960s as they prepared to launch their new 901 model. Curiously, the name of the Ferrari 308 was not a problem.[citation needed]
