Ford North America has backed tuning company Roush Performance with development of a high-output Focus RS with 372kW of power and three-way adjustable suspension.

Unveiled alongside tuned Mustang coupes and even Fiesta and Focus ST models at the SEMA show in Las Vegas this month, the Focus RS concept gets a shortblock performance assembly, cooling system and heavy calibration work in order to leap 115kW from the standard 257kW. No torque figure is given beyond the production model’s 440Nm.

PFC slotted brake rotors and Roush PerformanceTrakPak three-way adjustable suspension with camber plates are added underneath, and 255/35 R19 Continental ExtremeContact Sport tyres wrap around lightweight forged alloy wheels.

“With calibration work producing an impressive 500 horsepower, the lines between design and functional performance blur – transforming this into a true street/race car,” Ford US said in a statement.

If the styling isn’t to all tastes, then there are rival Focus RS alternatives that were likewise Ford-backed for SEMA.

The “stealth grey and fire orange” example even gets a carbonfibre driveshaft, upgraded CV axles and front limited-slip differential.

While Ford’s hottest hatchbacks are all seen here in concept form, performance parts are filtering into the American market now. Ford Australia has only backed Mountune performance parts for its Fiesta ST and Focus ST models locally, however, with word still to come through about potential Focus RS tuning kits for our market.
