“The Focus RS’s 2.3-liter turbocharged inline-four delivers power and torque as if the two have been packaged in a Kirkland-branded bundle. You get 350 of each-ponies and pound-feet-in a 3459-pound package. There’s also a trick torque-vectoring system that can shuttle as much as 70 percent of the engine’s thrust to a single rear wheel, a delightful six-speed manual, and enough grip to rival a Porsche.
The engine is a derivative of the Mustang’s EcoBoost four-cylinder, but you would never guess it from driving both cars. On top of an extra 40 horsepower and 30 lb-ft of torque, the Focus RS engine revs quicker, with a more linear power delivery and an exhaust note befitting a performance car. While the Mustang drones, the Focus RS buzzes and bristles with a deeper, louder, meaner tone. In Sport, Track, and Drift modes, the exhaust crackles, snaps, and pops.” -- Car And Driver
