Because Mercedes. Because Audi.
If you're in the market for a brand new Ford Focus RS, then you're really going to want to know about this. According to Autocar, Ford Performance is now considering a lighter and even faster version. How fast? Try 0-60 mph in less than 4 seconds, potentially. If this hardcore Focus RS were to happen, chances are it'd become the fastest-accelerating hatchback in history. So how does Ford plan to make this thing even better? Cut weight and add power to that 2.3-liter turbocharged four banger. But there's kind of a problem.
That engine is already operating at nearly full potential. More power will rely upon finding room for additional cooling capacity. Cutting weight, however, is easier. Options include "polycarbonate glazing, carbon fiber-reinforced plastic bodywork, forged aluminum suspension componentry, carbon fiber brakes, less noise insulation, and a stripped-out interior." All of that could save some 220 lbs. even after the necessary drivetrain additions. What would those entail? An electronically controlled limited-slip differential for the front axle that would be tuned to work the rear unit, as well as a dual-clutch gearbox in place of the manual.
If Ford manages to pull this off, this super-duper Focus RS would likely defeat rivals such as the Mercedes-AMG A45 and the Audi RS3 to 62 mph, at least. No timeframe was given regarding a launch, but we're willing to bet Ford is going to go for it. It's simply too tempting not to.
