Visually, both variants get a more pronounced grill and larger air intakes at the front while the rear remains largely similar. Both get new wheels too with the STi getting the variant's first-ever standard 19-inch wheels. The STi also sports new LED adaptive headlights.
Moving inside, both models come with new trim materials, faster remote trunk opening, thicker door glass, revised door sealing and a foam-filled windshield header beam that enhance comfort levels. Also new to the car is a 5.9-inch multi-function display that replaces the 4.3-inch unit in the dashboard.
Elsewhere, the WRX feature a re-tuned suspension on both axles, revised electric power steering, and enhanced shifter feel for the six-speed manual gearbox. Owners who want more from the car can opt for the Performance Package that adds red-finished brake calipers, upgraded Jurid brake pads, Recaro eight-way power seats, and removes the sunroof for weight reduction.
Meanwhile, its faster STi sibling also gets new suspension settings and an updated DCCD (Driver's Control Centre Differential) system. It is now fully electronically controlled for a smoother and quicker response.
Brakes on the STi have also been upgraded significantly. The car now uses stronger monoblock 6-piston calipers at the front, and 2-piston calipers at the rear, and larger, drilled rotors all around.
Powertrains for both variants remain unchanged, with the WRX using the same 2.0-litre turbocharged boxer engine that does 268bhp while the STi uses a 2.5-litre that outputs 305bhp.
