All the pictures with front brakes are the 1914 models...

Right click on the photo of the four cars lined up and click on 'inspect element' and you'll see in the title to the photo there that it's the 1914 Peugeot team.

Then you'll see that the front of these cars is narrower than the ones from the 1913 races, and the American races at San Diego and elsewhere as shown by Ken.
