Although no prices are yet available - they'll only be released in November - it's expected the high-performance STi will hit the scales at around R400 000, including a 3-year/100 000 km maintenance plan.
There will be seven models in the Impreza range, including both four-door sedan and 5-door Sportwagon derivatives, and engines will be either 2-litre normally-aspirated or 2.5-litre turbocharged.
The sporty WRX now boasts 169 kW and 320 Nm of torque, while the top-line WRX STi kicks out a lusty 206 kW and 392 Nm.
Naturally this boosts performance, with a claimed top speed of 255 km/h and a 0-100 km/h dash in just 5.5 seconds.
According to Subaru quality feel has been further enhanced while functionality has also been augmented in the newly designed front bumper, grille, and headlights, as well as in other interior and exterior design changes.
The STi also features an improved version of the driver's control centre differential (DCCD), an electronically controlled all-wheel drive (AWD) system that adds a torque-sensitive, mechanical limited-slip differential (LSD).
This gives less torque split to the rear wheels, changed from a maximum of 35/65 front/rear to 41/59 front/rear, for better balance.
The car's exterior design has been made more fully aerodynamic, in recognition of its participation in high-speed rally events and motor sport activities.
This means a small roof spoiler in addition to the giant "tea tray" on the boot, and there is also a front splitter and a rear diffuser.
Wheel sizes remain at 17 inches, and tyres unchanged at 225/45, but the wheels are now painted a lighter shade of gold.
