2018 Subaru WRX
KBB.com Review
Kbb.com Expert Rating
Unlike many cars in this class, the new Subaru WRX and STI are a blast to drive, rain, snow or shine, thanks to their sophisticated all-wheel-drive systems. If you like your speed balanced with 4-season usability, room for five and a sizable trunk, you’ll like these turbocharged sedans.
Both the WRX and STI are 4-door sedans. If you want the versatility of a hatchback, check out VW’s Golf GTI and Golf R, and Honda’s new Civic Type R. The 305-horsepower WRX STI is also light compared to the 350-horsepower Ford Focus RS, which is also all-wheel drive.
