About Subaru WRX

The Subaru WRX can trace its lineage back to the mid-1990s with the Impreza WRX, but it became a stand-alone model in 2013. The all-wheel-drive turbocharged four-cylinder is a wolf in four-door sedan clothing and offers a level of performance above other cars at the same price point. For the current generation, Subaru is offering the 2.0-liter turbocharged WRX with a traditional six-speed manual or, for the first time ever, a continuously variable transmission. It’s also offered in a higher spec STi version, which is powered by a turbocharged 2.5-liter four-cylinder boxer engine.
