Subaru has introduced the WRX STI Final Edition as an official send-off for the current generation to make way for more efficient platforms that may involve electrification. The Japanese automaker will only be making 150 cars for the UK market, and it comes with the latest bells and whistles.

First of the lot is driving performance, which has been improved by changing from mechanical and electronic to fully electronic control of the Multi-Mode Driver’s Control Centre Differential (DCCD). This provides the vehicle with optimum cornering ability, by shifting power to the wheel that needs it most.

Wheel size has been increased to 19-inches to accommodate the larger Brembo brakes with yellow painted calipers. This new setup improve fade-resistance and brake performance as well as offer a consistent pedal feel. Subaru says that the improvement will prove exceptionally useful when driving at the car’s limit.

Visual disparities between the Final Edition and the regular WRX STI are subtle at best. It gets Final Edition badges and a redesigned front bumper that houses the lower grille blacked out with a geometric textured panel. The signature hexagonal grille has been sharpened with a black surround outline.

Inside, Subaru has given the car high gloss black inserts for the instrument panel, gear stick surround, door panels that complement the steering wheel with red stitching and red seat belts. The front seats are now heated, and a larger 5.9” multi-function display has been added to the top of the dash.

Like models that preceded it, the Final Edition gets bi-functional projector LED lights, with a single bulb enabling High Beam Assist to switch between high and low beam automatically. There’s a single-lens camera embedded in the font windscreen that detects on-coming traffic and this allows the headlights to switch to a different light intensities.

The Subaru WRX STI Final Edition has already gone on sale in the UK and it won’t be long before all 150 vehicles are snatched up.
