The next Subaru WRX will be using a smaller engine but have more power. Motor Trend has found out from a Subaru spokesperson the next WRX will use a 2.0L turbo variant of the FA20 engine found in the new BRZ.
Although the new engine is half a liter smaller in displacement than the current WRX’s 2.5-liter 265-horsepower engine, Subaru is targeting a 270 HP rating.
So why a smaller displacement? Part of it is due to fuel economy. The current WRX gets EPA rating of 19 city and 25 highway. Subaru recently announced the new FA20 engine to get 30 mpg highway.
The move also signals a change Subaru announced awhile ago with the Impreza and WRX/STi going their separate ways. The new Impreza 2.0L flat four from the FB family of engines found in the Forester SUV and other models. The engine does not feature the same compact dimensions, 86 mm x 86 mm bore and stroke, or complex D4S port/direct injection technology as the FA20 engine.
