WRX STI models are powered by a turbocharged and intercooled 2.5-liter DOHC Boxer engine producing 293 horsepower at 6,000 rpm and 290 lb.-ft. of peak torque at 4,400 rpm. The Subaru Active Valve Control System (AVCS) variable valve timing technology helps provide strong torque characteristics throughout the engine’s operating range. A manually operated water spray feature helps to bolster intercooler efficiency during spirited driving.
All WRX STI models are exclusively equipped with a 6-speed manual transmission that features carbon-plated double-cone synchronizers on 4th, 5th and 6th gears to help ensure durability.
