| The GH-GDB model was added to the Subaru Impreza line in Oct. 2000 as an STi edition with higher dynamic performance. Cooling performance was improved by increasing the size of the intercooler and air intake. Engine performance was boosted by an improved turbocharger, and application of a seamless valve lifter, and active valve control system (AVCS: a variable valve timing mechanism), etc. Other applications included a newly developed cross ratio 6-speed manual transmission to receive the high torque, a high rigidity inverted strut suspension, 17-inch ventilated disc brakes, and the like, resulting in further improved driving performance while maintaining the necessary ease of handling for day-to-day driving. The speed and quality driving feel of the Impreza STi gave it impressive dynamic performance, and enhanced its potential for motorsports. |
