The wait is finally over. Subaru has released official photos and initial info on the new JDM-spec Impreza WRX STI. Details remain scant, however, as Subaru only tells us that the new STI is powered by a 16v 2.0L boxer with a twin-scroll turbo mated to a 6-speed manual. SI-DRIVE, multi-mode Drivers Control Center Differential (DCCD) and Vehicle Dynamics Control (VDC) are also standard. All of these things have been widely speculated on and/or reported already. Specific power numbers are conspicuously absent, so we'll have to wait for the rest of it when the car bows in Tokyo in a couple of weeks. Based on what's already been leaked, look for 304 horses and 311 lb-ft of torque in the Japanese-market model. What's no longer a mystery is the car's appearance, which is muscular and aggressive -- a huge improvement over the base WRX.
