The hardcore hatchback could hit 60 mph in under 4.0 seconds.Ford is reportedly developing an even more hardcore Focus RS variant.The high-performance hatchback's 2.3-liter EcoBoost engine is said to be nearly maxed out at 350 horsepower and 350 lb-ft of torque, leaving little room for additional power.
Engineers are instead focusing on material upgrades to improve the car's power-to-weight ratio, Ford insiders have told Autocar. Expected tweaks include carbon-fiber bodywork, aluminum suspension components, reduced noise insulation and a stripped-down interior.
The track-focused RS will reportedly receive a few other changes to improve handling, including an electronically-controlled limited-slip differential for the front axle and a dual-clutch gearbox.
Despite the added heft of drivetrain upgrades, the limited-edition RS is expected to be at least 220 pounds lighter than the standard production model. Engineers are said to be targeting a zero-to-60 mph sprint in less than four seconds, quick enough to beat the Mercedes-AMG A45 and Audi RS3.
Launch timing and pricing were not cited in the report, though the upgraded RS could be even more expensive than its German benchmark rivals.
