2007 Subaru Impreza WRX tuned by STi

Subaru like to sell cars, they do it in many ways, apart from building quality cars and providing bang for your buck, they also love to milk their STi badge (as is the point of having a Halo car, to increase sales of lower models).

With that mind, Subaru has made an early 2007 impact with the launch of a tuned by STI limited edition version of its popular Impreza WRX.

Priced at $46,990, ($7,000 more than the standard WRX), the Impreza WRX tuned by STI includes more than $12,000 worth of extra equipment. Enhancements include

  • tuned Engine Control Unit (ECU),
  • Pirelli tyres,
  • Enkei alloy wheels,
  • leather trim
  • sunroof
  • STI front lip spoiler (reduces lift and drag)
  • different sports suspension,
  • lowered springs,
  • tuned struts,
  • larger front stabiliser bar,
  • more effective rear stabiliser bar mounting and pilot ball rear suspension arms
  • aluminium gear knob
  • short shift gear linkage

Subaru says that better engine performance has been achieved by recalibration of the ECU as well as a low back pressure exhaust muffler. So how much more have they managed to squeeze out of this 2.5L engine?

Subaru figures suggest that peak power is up 10 kilowatts to 179kW, while torque is up 20 Newtonmetres to 340Nm, peaking at 3200rpm. However 0-100km/hr time is still at 5.9 seconds. Same as the standard WRX (half a second slower than the STi)

“This locally tuned variant has put a priority on low down engine performance. We’ve used specialised STI engine tuners from FHI to tailor this car to suit Australian conditions and provide an exhilarating, high performance package.” Nick Senior, Managing Director, Subaru Australia said

Although if you were game, for the extra $7,000 you can easily modify your standard WRX to put out a significantly more amount of power/torque than the "tuned by STi" version, however Subaru is quick to point out that the new car is significantly more aggressive than a standard Impreza WRX.

Furthemore, much like the Club Spec WRXs, All limited edition vehicles feature specially designed, individually numbered “tuned by STI” badges. The cars are only available as a manual sedan in WR Blue with shadow chrome wheels, or Obsidian Black with charcoal wheels, only 200 vehicles will be sold.
