The car is powered by the 2.5-litre Subaru boxer 16-valve turbo engine with Dual Active Valve Control produces 300 hp and 407 Nm of torque.
While these outputs are unchanged from the outgoing STI, improved torque delivery throughout the rev range translates into better response and more linear acceleration. The 0 to 62 mph (100 km/h) sprint is achieved in just 5.2 seconds.
For 2011, Subaru has further tuned its three-mode SI-Drive (Subaru Intelligent Drive) system, which can be used to adjust the engine’s characteristics to best suit a variety of driving conditions.
“The car features a default setting of 41 / 59 per cent front / rear torque distribution for optimum balance, and the driver can adjust this while on the move using the four-mode (Driver’s Control Centre Differential) system. The WRX STI also incorporates Multi-Mode VDC, Subaru’s advanced electronic stability control (ESC), allowing the driver to modify the point of intervention of this electronic driver aid to suit their own tastes or driving conditions,” a company statement reads.
Standard equipment includes keyless entry, push-button start, front log lamps, hill start assist, climate control air-conditioning, remote central locking, electric windows front and rear, an all-new radio-CD unit with a 10-speaker audio system, AUX and USB input jacks, hands-free Bluetooth system and cruise control.
