Just don't expect anything too glamorous
There's no denying that the RS is outstanding as a driver's car, but its sharp duds are covering an aging body. The Focus, as we know it, is nearing the end of its lifecycle, and the interior has some hard plastics and tired-looking graphics. Ford could have taken a page from Volkswagen or Subaru and installed (or at least offered) a steering wheel befitting its sportiest offering.
The best thing that Ford did for the RS was introduce Sync 3, the latest iteration of its proprietary infotainment system, on the large, center-mounted screen. Some have said that Sync 3 is a user-interface nightmare, but its voice-recognition technology is second to none. You can tell your RS to change the song, pull up Maps, or send a text. It listens. Beyond that, it's refreshing how low-tech the RS really is. You hardly need a YouTube tutorial to figure out how to put the fantastic six-speed manual into gear. Turn off the auto start-stop when you get to the track, and leave it on in traffic.
