Our spies in Germany came across a pair of disguised Ford Focus STs, which could be one of two things - a refreshed 2015 model undergoing shakedown testing or development mules for the upcoming 300-horsepower-plus Focus RS.
Both right and left-hand-drive models bearing British number plates were spotted, underscoring the fact that Ford has relied heavily on both its British and German operations to develop the Focus ST.

The Focus ST theory
While the photos don't reveal many changes, they do clearly indicate that Ford is working on a new grille for the Focus ST. The hood and headlamps appear to be unchanged, but the grille itself will get a new treatment.

Ford is likely to retain the current Focus ST's honeycomb-style finish, but the shape of the grille might change to better reflect the Aston Martin "inspired" appearance Ford has been applying to the rest of its lineup.

Major powertrain changes aren't expected, but the entire Focus lineup is said to be slated for an upgraded interior.

The Focus RS theory
Are these test mules hiding the new 2.3-liter turbocharged four-cylinder engine that will power both the 2015 Ford Mustang and the upcoming Focus RS? It's hard to say for certain.

What we are pretty confident about is that the new Focus RS - which may or may not be slated for North America - will boast upwards of 330 horsepower sent to the front wheels via Ford's innovative, torque steer-negating revoknuckle front suspension component.
