2006 Subaru Impreza WRX STi

Subaru has introduced a restyled and re-powered Impreza model line for 2006, also adding three new WRX models, more safety features, and a revised Symmetrical All-Wheel Drive system in the 300-horsepower WRX STI.

The new Impreza shows a drastically different design approach, one which is probably motivated by Subaru’s new designer, Andreas Zapatinas of ex-Alfa Romeo fame. One particular area of interest is the front end. It features a controversial three part grill, a design we first saw from Subaru on their 2003 Subaru B11S Concept. Whether or not the new face and hood-top character lines gel with the rest of the car remains for the viewer to decide. In either case, Subaru have really upped the ante against the very evolutionary Mitsubishi Lancer IX.

The 300-horsepower Impreza WRX STI gains a further edge in all-wheel drive performance for 2006. The power distribution ratio in its advanced Driver Controlled Center Differential (DCCD) version of Symmetrical All-Wheel Drive has been changed from 35:65 to 41:59 and uses a new mechanical limited slip center differential in place of the previous hydraulically controlled unit. The addition of a steering sensor to the differential’s control inputs further enhances torque transfer and overall performance of the AWD system.

The WRX STI accents the Impreza re-style with new design features of its own. A new roof vane spoiler, as used on the Impreza WRC rally car, contributes to stability at track speeds. The new rear underbody diffuser and new side sill spoiler design ensure the WRX STI will turn heads while cheating the wind. The lower-profile hood scoop from the standard WRX aids forward visibility but maintains airflow to the intercooler due to the improved aerodynamics of the redesigned front-end. The WRX STI also gains daytime running lights (DRL).
