An icon on the rally circuit, the Subaru WRX (and the STI) has been a separate model since 2015 rather than just a variant of the Impreza. The WRX typically comes with a turbocharged 2.0-litre 268-horsepower engine, while the STI offers a 305-horsepower 2.5-litre. In both instances, there's a factory-standard 6-speed manual transmission, but buyers can also opt for an automatic CVT, which is a first for this duo of all-season sports cars.
