While the 2017 Impreza is all-new, the Subaru WRX and STI are going to have to make do with a minor update for 2018. Subie has provided the two athletic cars with a new face and a host of mechanical tweaks that should appease buyers, but the fact all-new ones are still about three years out is a tough pill to swallow.
Most obviously, both WRX and STI have new front fascias for 2017. The new clip puts both cars more in line with the Impreza from a design language perspective. And Subaru says the fascia changes are not just cosmetic, but also include more robust safety for collisions. Win, win.
Aside from the design changes, both cars have new wheels and larger brakes. The STI has been upgraded to six-piston Brembos in the front and two-piston rears with larger 19-inch wheels wrapped around them. The Brembos will be clinching to new cross-drilled rotors as well.
The STI in general has seen more mechanical modifications. Subaru has swapped the mechanical limited-slip differential for an electronic one. The tires have also been widened, while both STI and WRX have new suspension tuning, while WRX solely has a revised clutch as well.
Both cars are also carrying over their current powertrain setups, which isn’t a particularly bad thing. That means the WRX will continue on with its 268 horsepower 2.0-liter turbocharged inline-four, while the STI will soldier on with a 305 horsepower 2.5-liter turbocharged inline-four.
Inside Subaru has upgraded the materials used in both cars, including softer touch dash components. The company also claims that both cars will be quieter thanks to more sound deadening materials in the cabin.
Subaru hasn’t stated when the 2018 WRX and STI will be available.
