Subaru Impreza WRX Bites Back

10th December, 2008

Subaru’s Impreza WRX All-Wheel Drive performance car has put the boot in for model year 2009, adding power, torque and a raft of other ingredients.

Subaru has unleashed sedan variants to complement the new generation hatch – and both body styles share the same turbocharged technical advances.

The 2.5 litre turbocharged engine now produces 195 Kilowatts of power at 6,000 rpm and 343 Newtonmetres of torque at 4,000 rpm.

While Impreza WRX is meaner, it’s also greener - lower fuel consumption and emissions result from the engineering refinement.

Fuel consumption is improved in the combined cycle from 10.7 l/100km to 10.4 l/100 km, while carbon dioxide emissions are down from 252 grammes/kilometre to 247 g/km.

Among the highlights, Impreza WRX offers:

  • 0-100 km/h time improved from 5.8 seconds (MY08) to 5.31 seconds
  • 26 Kilowatts more power
  • 23 Newtonmetres more torque
  • Increased boost
  • Enhanced suspension package - sharper handling
  • Better fuel efficiency (combined cycle/ADR 81/01)
  • Carbon dioxide emissions reduced
  • Options of leather trim with sunroof, and satellite navigation
  • New mesh grille, with WRX badges
  • Distinctive red brake calipers
  • Wider tyres
  • Red stitch seating and steering wheel adds to sporty appearance
  • WRX logos on front seats
  • Pricing maintained at MY08 levels – simple choice between hatch or sedan, as prices identical

Nick Senior, Managing Director, Subaru Australia, said: "Controlled aggression sums up the MY09 Impreza WRX – it performs better across the board, from power and torque to carbon footprint, which is a major engineering achievement."

"New generation Impreza WRX hatch opened up a whole new stream of customers for us."

"Now the introduction of the sedan, combined with a raft of enhancements, gives us the opportunity to take the WRX profile to a whole new level."

Mr. Senior said the new generation Impreza range is a winner across the board, with sales up 7.0 per cent to the end of October.

"We’ve had amazing customer acceptance of new generation Impreza, and early indications since the introduction of sedan variants in September are that it’s going from strength to strength."

"Our safety message combined with a fun driving experience, durability, excellent whole-of-life costs and resale value, continue to attract new customers to Subaru."

Model Year 2009 Impreza WRX is on sale now.


Red stitching is added to Impreza WRX seats and steering wheels and the WRX logo features on front seats.

For the first time, the car is available with the options of leather with sunroof, satellite navigation or the combination of leather, sunroof and SatNav.

A 60/40 split/fold rear seat optimises cargo carrying options.


Impreza WRX sports a variety of exterior changes, producing a bold new look.

Wider Dunlop SP Sport 01 225/45R17 tyres combine with a new mesh grille and WRX badges front and rear, for added visual distinction.

Impreza WRX sedan features a boot lid spoiler and the hatch a rear roofline spoiler.

Red brake calipers differentiate WRX from other Impreza variants.


All variants:
Obsidian black pearl, Satin white pearl, Spark silver metallic, Dark grey metallic, Lightning red and WR blue mica.


Impreza WRX’s 2.5 litre turbocharged engine now produces 195 kW of power at 6,000 rpm, up 15.4 per cent, and 343 Nm of torque at 4,000 rpm, up 7.2 per cent.

Maximum turbocharger boost is increased from 78 kPa to 92 kPa.

A revised exhaust system provides a 30 per cent reduction in gas flow restriction, to match the turbo charger performance and increase engine power.

The changes have produced a quicker car:

Significant testing was conducted in Australia and Japan to tune suspension settings for local conditions.

MY09 Impreza WRX is biased towards sports handling, while retaining good ride comfort, grip and stability when driven enthusiastically.

The coil springs, stabilisers and top mounts are stiffened and roll rigidity increased to improve maximum lateral G and turning ability.

Fine tuning of the damping forces in the shock absorbers provides linear response with minimal delay when steering.


Improved shift feel is achieved in the transmission through use of a ball type key for the first and second gear synchro hubs and a change to the key groove on third and fourth synchro sleeve.

Hardened materials are used for the main shaft and first driven gear, while operation of the clutch slave cylinder now incorporates an orifice valve to protect the drivetrain during rapid clutch engagement.


A damper valve is added to the steering gearbox to reduce kickback, particularly when cornering on rough roads.

Wheels and tyres

Wheels and tyres were chosen to complement the suspension springs, damping and bushing, to ensure optimum grip and ride comfort.

The tyres also optimise the balance of dry and wet weather grip, steering response, NVH levels and ride comfort.

Tyre width is increased to 225/45 from 205/50, benefitting grip and handling performance, to match the sports suspension setting.

MY09 Impreza WRX is fitted with Dunlop SP Sport 01 225/45R17 tyres and 17 x 7 JJ alloy wheels.


In line with Subaru’s safety commitment, Impreza WRX sedan maintains the five-star rating for occupant safety from the independent Australasian New Car Assessment Programme (ANCAP).

All Imprezas also share a four-star rating for pedestrian safety.

Since the introduction of model year 2009 Liberty and Outback in October, every Subaru now has standard electronic stability control.
