Subaru says the new STI has undergone extensive testing at the Nurburgring and race tracks in Japan to fine tune its suspension (now lower by 5mm). Of course the biggest news for 2011 model year is the addition of a new variant: Impreza WRX STI in sedan form.
“We can confirm a four-door Impreza WRX STI will join our Australian line-up much later in the year and will be available from our exclusive STI retail network.” Nick Senior, Managing Director, Subaru Australia, said:
Power is at 227kW (305 hp) and 392Nm of torque is delivered to all-wheels through a six-speed transmission. There is no official 0-100km/h time announced so far. Now that the new WRX Sedan features the aggressive wide body stance, the STI variant has to prove its value over its related siblings.
On top of the previous design the STI sedan has larger bumper corners with areas surrounding the fog lamps blacked out for that extra mean look. There is also a new-look front grill highlighted by its virile black tones.
If you look hard enough you'll also notice a refined forward-surging shape for the lip spoiler at the bottom of the bumper. This addition is seen on both hatch and sedan models.
The front of the sedan variant will now look pretty much the same as the hatch version thanks to the adoption of external features such as the blister fender running from the front to the rear.
From the back we can see a different design emerge, the rear fender surface is further stretched beyond the outer side of the combination lamps. Subaru says the new look will emphasis "thickness of the rear end" and hence stability. To add some more aggression to the rear-design, the rear bumper now completely surrounds the muffler.
As you may have noticed from our previous articles, the well and truly missed oversized WRX STI spoiler is finally back with the introduction of the sedan variant.
Other external changes include:
- The twin-dual stainless steel muffler cutters
- Lightweight 18-inch aluminum wheels with a high luster finish.Additionally,
- The optional BBS 18-inch wheels are also now avilable with a high luster finish.
- A new colour called "Plasma Blue Silica" joins the range for both body shapes
Moving inside the most obvious upfront change is the instrument panel, door trim and steering decorative parts which have all changed colour to a dark metallic hue. Subaru says the change was made for better contrast and emphasis on creating a sportier cockpit.
A Bluetooth mobile phone handsfree kit has also found its way onboard, operated via new buttons on the steering wheel. Music lovers will be happy to know that Subaru has finally added a USB jack for USB input devices (iPods/iPhones etc).
More technical detailed changes include a new aluminum lower arm now in use for the front suspension. The rear arm bushes have also been modified to a pillow-ball type. Digging further in we can also note that the sub-frame bushing specifications for the rear suspension have been altered to improve toe and camber rigidity.
Subaru says that all technical changes (as invisible as they are) have greatly improved roll rigidity.
