The 2021 WRX comes with a choice of two horizontally opposed turbocharged engines. Having a turbocharger attached to either WRX model offers great benefits, the punch of power as the engine comes up on boost makes it easy to merge and dart through traffic on the surface streets or merging on the freeway.
WRX models get a 2.0 liter turbocharged and intercooled four-cylinder engine with 268 horsepower and 258 pound-feet of torque. It provides supreme power for anything it is asked to do while returning good fuel economy - up to 27 MPG on the highway. WRX STI models have the 2.5-liter turbocharged four-cylinder engine with 305 horsepower and 290 pound-feet of torque for extreme power.
The horizontal layout of the Boxer® Engine allows for better balance and less vibration between pistons, which lets the engine perform more efficiently and effectively, as can be seen in the stats above. Gearheads will tell you working on a Boxer® Engine is more like working on an aircraft engine. It is made to soar!
Both engines are connected to a six-speed manual transmission. A Sport Lineartronic® CVT transmission with SI-Drive is available on the WRX only.
Track-Tuned Suspension allows for aggressive spring and damper rates. Double-wishbone rear suspension with pillow ball bushings, large front and rear anti-roll bars, wide tires, and rigid unibody with reinforced suspension brings the motorsport feel and the most responsive handling to the grip of your hands on the steering wheel. Vehicle Dynamics Control with Active Torque and Electric power steering further sharpens cornering and actively reduces understeer and gives instantaneous response to your command.
6-Piston Front and 2-Piston Rear Brembo Brakes are found on all WRX STI models. The easily recognizable yellow-finished monoblock calipers and large cross-drilled rotors give WRX very responsive braking with good feel and fade resistance.
