The WRX is a performance-tuned variant of the highly-acclaimed Subaru Impreza, which ranks well in affordable small cars for its impressive road handling and excellent performance in federal government and insurance industry crash tests.
The Impreza WRX features a 2.5-liter DOHC intercooled, turbocharged four-cylinder Subaru Boxer engine that generates 265-horsepower at 6,000 rpm and 244 pound-feet of torque at 4,000 rpm. While the WRX STI trim comes equipped with the same Subaru Engine, it produces considerably more power -- 305-horsepower at 6,000 rpm and 290 pound-feet of torque at 4,000 rpm. The WRX and WRX STI Imprezas are mated to a fully synchronized five-speed manual transmission and close-ration six-speed manual transmission, respectively.
Unique to the STI is Subaru Intelligent Drive (SI-DRIVE), a system that enables drivers to choose from three vehicle performance modes that regulate its engine control unit (ECU) and fine-tune its electronically controlled throttle.
All WRX models employ Subaru's Continuous All-Wheel Drive system, which defaults to a 50/50-split front-to-rear torque distribution. In the event that wheel speed differs between the front and rear axels, Subaru's all-wheel drive system will distribute more power to the wheels holding the most traction. The STI's all-wheel drive system slightly differs in that it has a Driver Controlled Center Differential (DCCD), which analyzes vehicle inputs to determine optimal torque distribution.
