As with previous photos, Ford engineers continue to heavily camouflage the front end of the RS prototypes, but there's a big difference here. Unlike earlier ones, this example appears to have a closer-to-production-ready front bumper rather than just a horizontal strip for the license plate. That may point to development getting somewhat closer to wrapping up. Although, this one lacks the larger rear wing from prior testers, and the exhaust also appears to be a work in progress with the rear diffuser covered in mesh in these latest shots.
The RS is rumored to be using the 2.3-liter turbocharged four-cylinder from the 2015 Mustang, but power is reportedly turned up from 310 horsepower in the 'Stang to somewhere between 325 hp and 350 hp for the Focus. Routing all that just through the front wheels could be a recipe for serious torque steer, and all-wheel drive is potentially being used for better traction.
Unfortunately, no release date is known for the RS yet, but we keep seeing evolution in the test mules. Indications point to it eventually going on sale for the US market, too. Until then, see what you think of these latest spy shots in the gallery.
