The 300 test mule (not pictured) is wearing a set of 315-mm tires, which were also worn by early Dodge Demon prototypes. Because of the wider rubber, the wheels stick out further from the wheel wells, thus making it likely Chrysler will tack on wider fender flares to cover the tires. Also spotted on this particular 300 mule were four-piston Brembo brake calipers, similar to those on the 300 SRT. Autoblog's spy photographer also claimed this 300 sounded like it had a supercharged Hellcat V8 under its hood. So how can this all be interpreted? Here's our theory: Chrysler is prepping a 300 Hellcat for the Australian and Middle Eastern markets.
