Subaru has confirmed that the STI-enhanced version of its new 2015 WRX will debut next week at the 2014 Detroit Auto Show. The new WRX STI will join the regular WRX in showrooms this spring, also as a 2015 model, and like the previous generation will build upon the regular car with stiffer suspension, increased output and more aggressive styling.

Peak output should match or come close to the 305-horsepower rating of the outgoing WRX STI, most likely derived from an upgraded version of the regular WRX’s turbocharged and direct-injected 2.0-liter four-cylinder. It’s also possible that a larger 2.5-liter unit may be fitted instead. A six-speed manual is likely to remain the only gearbox option.

We’ll have full details soon, as the covers will come off the new 2015 Subaru WRX STI on January 14. To stay up-to-date on all the happenings at the Detroit Auto Show, be sure to bookmark our dedicated hub. And for more on the 2015 WRX, check out our first drive report.
