Best of all, the WRX and WRX STI models carry on as cars that are out-and-out fun to drive – the WRX is nimble and quick, and the WRX STI remains a serious technological tour de force. These cars excel at acceleration and handling.
Both cars have longitudinally mounted, turbocharged, 4-cylinder SUBARU BOXER engines. In the WRX, the engine develops 265 horsepower and 244 lb-ft of torque. The WRX STI turns it up a notch with 305 horsepower and 290 lb-ft of torque. Peak torque for both engines is at 4,000 rpm, which contributes to their drivability. In stock form, these cars are capable of accelerating from zero to 60 miles per hour in less than five seconds.
Symmetrical All-Wheel Drive transfers engine power to the wheels with the best traction. In the WRX STI, the driver can tailor powertrain systems to his or her personal taste with:
- Subaru Intelligent Drive, which selects from three different engine modes
- Driver Controlled Center Differential, with automatic and manual settings that set the percentage of torque distribution between the front and rear wheels
- Vehicle Dynamics Control, which offers Standard, Off, and performance-oriented traction modes
The braking system on the WRX STI matches its upgraded power and powertrain. The WRX STI chassis system features a Brembo®1 performance brake system and available BBS®2 ultra-lightweight wheels.
Suspensions for both models were tuned on race tracks. The WRX STI suspension has an inverted strut and aluminum-alloy lower L-arms in front. Both cars have a handling-oriented, double-wishbone rear suspension.
Summer performance tires on the WRX and ultra-high-performance tires on the WRX STI contribute to dynamic acceleration, braking, and cornering – all the things an enthusiast enjoys.
