The limited-edition model gets a limited-slip differential.

Ford is sending off the Focus RS after the 2018 model year. The Blue Oval's performance division is celebrating the end of the hot hatch's short production run by launching a limited-edition model.

Offered in Nitrous Blue or edition-specific Race Red, the commemorative RS receives gloss black paint on the roof, the mirror caps, and the rear spoiler. 19-inch forged alloy wheels with blue center caps come standard.

Inside, the door handles, the handbrake lever, and the turbo boost gauge bezel are wrapped in carbon fiber skin. Every 2018 car comes standard with the RS2 Package, which adds heated and leather-upholstered Recaro bucket seats, a heated steering wheel, heated mirrors, and a voice-activated navigation system. The RS2 Package was a $2,785 option for the 2017 model year.

The RS carries on with a turbocharged 2.3-liter EcoBoost engine that sends 350 horsepower and 350 pound-feet of torque to all four wheels via a six-speed manual transmission. The 2018 update adds a limited-slip front differential.

Production of the 2018 Ford Focus RS is limited to 1,000 examples for the United States, and 500 cars for Canada. Pricing information hasn't been announced yet.

A next-generation Focus built on a brand-new platform is right around the corner. A RS model won't be available at launch, but the nameplate is guaranteed to return sooner or later.
