据国外汽车杂志《TruthAboutCars》报道，2019款斯巴鲁WRXSTI功率将达到310马力。根据提交美国国家公路交通安全管理局的文件显示，该车搭载的2.5升四缸涡轮增压引擎功率增加了5马力。而WRX搭载的2.0升引擎功率为268马力。不过，斯巴鲁北美公司拒绝对此作出表态。虽然斯巴鲁在尽力榨干2.5升引擎的动力性，但300马力的功率还是无法与包括奥迪RS3和奔驰-AMG CLA 45 4Matic这样的车型进行竞争。而将于2020年发布的下一代WRXSTI很可能搭载取自Ascent三排座SUV的2.4升水平对置四缸涡轮增压引擎。该引擎不仅配备了更大涡轮增压器，而且还将提供轻混系统。

2019 Subaru WRX STI All But Confirmed To Develop 310 Horsepower

According to The Truth About Cars, the WRX STI will get 310 horsepower as well for the model year 2019. The information comes courtesy of a “VIN decoder document sent to the National Highway Traffic Safety Administration,” which shows the 5-horsepower increase for the 2.5-liter turbocharged boxer four-cylinder.

 

The 2.0-liter in the WRX, meanwhile, stays put at 268 horsepower. When questioned about the document sent to the NHTSA, the peeps at North American Subaru replied that it’s “too early for us to comment” on the matter. Reading between the lines, it’s just a matter of time until the upgraded WRX STI goes official.

 

As a side note, Subaru is milking out the 2.5-liter since what appears to be forever. The automaker has been pushing 300 horsepower or thereabouts out of that engine for a long time now, which is not competitive when compared to the likes of the RS 3 and Mercedes-AMG CLA 45 4Matic. This gets us to the next-generation WRX STI.

 

Expected to drop in 2020 alongside the WRX, the STI is likely to get the 2.4-liter turbocharged boxer four-cylinder from the Ascent three-row SUV. With a larger turbocharger and a bit of electrification, most probably of the mild-hybrid variety.
