About the Ford Focus RS

The Ford Focus RS was Ford’s version of a sporty compact. Essentially, it was a compact hatchback or sedan that had a Mustang engine. Originally launched in 2009, the RS expanded the power of the Focus ST with a 2.5L engine.

The Focus RS became a consumer favorite for its style and its power. Ford continued to improve performance of the Focus RS including all wheel drive and additional drifting capabilities. Ford Focuses have been featured in both touring and rally car races.

Ford Focus RS Performance Parts

Affordability and power is a major incentive for Focus drivers. When it comes to modding or upgrading performance, the Ford Focus RS price point, stock components, and straightforward engineering make it a go-to vehicle for performance upgrades and enhancements. Prominent models for upgrades include the 2016 Ford Focus RS, Ford Focus RS 2013, the 2015 Ford Focus RS, and the 2019 Ford Focus RS.

Compared to other popular Ford sport models like the Fiesta ST and the Mustang Ecoboost, the Focus RS offers abundance of power, handling, and customizations.
