New models - Subaru - Impreza - WRX tuned by STi
Subaru offers 200 reasons for special STi
Subaru tuning tweaks and free-flowing exhaust boost WRX power to 179kW
29 Jan 2007
SUBARU launched a "tuned by STi" limited-edition version of its popular Impreza WRX.
Priced at $46,990 the Impreza WRX tuned by STi includes more than $12,000 worth of extra equipment for only $7000 more than the standard Impreza WRX.
Just 200 versions will be available.
Enhancements include a tuned Engine Control Unit (ECU), Pirelli tyres, Enkei alloy wheels, leather trim and sunroof.
Improved engine performance has been achieved by recalibration of the ECU and is combined with a low back pressure muffler.
Peak power is up 10kW to 179kW, while throttle and torque response is significantly enhanced with torque up 20Nm to 340Nm, peaking at 3200rpm.
Fuji Heavy Industries' Subaru Tecnica International worked to give the car a more linear throttle output and improved torque curve to ensure the car was very responsive.
According to Subaru managing director, Nick Senior, the locally tuned model placed a priority on low down engine performance.
The addition of genuine STi sports parts including sports suspension, lowered springs, tuned struts, larger front stabiliser bar, more effective rear stabiliser bar mounting and pilot ball rear suspension arms results in sharp, responsive handling.
Lightweight 18-inch STi Enkei alloy wheels with wider Pirelli P-Zero Nero tyres complete the handling upgrade.
Aerodynamics are improved with the addition of an STi front lip spoiler which reduces lift and drag.
Combined, the technical and aerodynamic enhancements make this car significantly more aggressive than a standard Impreza WRX.
Apart from the sunroof, interior upgrades include leather trim, aluminum gear knob and short shift gear linkage to significantly improved gear shifting.
All vehicles feature specially designed, individually numbered "tuned by STi" badges.
The car will be available as a manual sedan in WR Blue with shadow chrome wheels, or Obsidian Black with charcoal wheels.
