The next generation of the Subaru WRX will receive a turbocharged 2.0-liter engine producing about 270 hp. Motor Trend reports that the 2013 WRX’s engine will be based on the new FA20 engine that powers the 2013 BRZ sports coupe.
The move to a 2.0-liter mill would represent a downsizing of the WRX’s powertrain. Currently the all-wheel-drive rocket uses a turbocharged 2.5-liter boxer-four engine rated at 265 hp and 244 lb-ft of torque. Moving to a smaller-displacement engine could help raise the car’s fuel economy over its current EPA ratings of 19/25 mpg (city/highway). If the estimated output of 270 hp holds true, the next WRX could deliver more performance while burning less fuel.
The new WRX engine will reportedly be a turbocharged version of the FA20, a 2.0-liter boxer-four that debuted in the Subaru BRZ, Toyota GT 86, and Scion FR-S. That naturally aspirated engine is rated for 197 hp and 151 lb-ft. We expect the 2013 Subaru WRX will be launched in 2012.
By 2014, it’s possible that the WRX and even-faster STI models will diverge more from the regular Impreza than they do currently. Reports suggest the WRX and STI will switch to a shorter platform with bespoke engines, instead of simply building off the platform and powertrains used for the standard Impreza line.
