2011 Subaru Impreza WRX STI spec C

Along with the WRX STI tS and A-Line tS , the Japanese market will also be receiving the Impreza WRX STI spec C to throw in all of our faces. This new version is already on sale in the Land of the Rising Sun.

The Subaru Impreza WRX STI spec C version is distinguished by an aluminum engine hood, laminar window glasses, and a downsized battery, all successful in reducing the vehicle’s overall weight. The newly-designed lightweight 18-inches alloy wheels are also brand-spanking new and are wrapped in Bridgestone POTENZA RE070 tires in 245/40R18 dimensions. Recaro seats with SRS front side airbags and SRS curtain airbags are available as an option.

Thanks to an optimized ECU programming, new ball-bearings for the twin-scroll turbocharger, and the reduced weight, the 2.0 liter turbo engine now delivers a total of 304 HP and 430 NM of torque.

The new spec C also gets colored "brembo" brake calipers and specially tuned front and rear suspensions that help the chassis offer stable and linear driving control even in marginal driving conditions.

Press release

Fuji Heavy Industries Ltd. (FHI), the maker of Subaru automobiles, today introduced the "Subaru Impreza WRX spec C", a new addition to the current WRX STI line-up. The model goes on sale today through Subaru dealerships in Japan.

Based on the Impreza WRX STI, the iconic sport model of Subaru, the WRX STI spec C model features enhanced engine and chassis performance as well as a lighter body on the premise of driving in motor sports. The model further strengthens its presence in the high performance car arena by offering sheer excitement and unique driving sensations as a distinctive sport model, in line with the performance level originally delivered by the Impreza WRX STI.

The twin scroll turbocharger newly adopted ball bearings for the turbine axle bearing, and the ECU (Engine Control Unit) program was also exclusively tuned. Thus the engine of the spec C model increases the maximum torque, and provides quicker response and improved accelerating performance. The adoption of an aluminum engine hood, laminar window glasses and a downsized battery resulted in a lighter body, which further refines the model’s driving performance. Thanks to its specially tuned front & rear suspensions, the chassis offers stable and linear driving control even in marginal driving conditions.

Subaru further enhances the WRX STI line-up by introducing this STI spec C model, in addition to the regular WRX STI model and STI A-Line model, the AT version.

Outline of Subaru Impreza WRX STI spec C

Enhancement of Engine performance:

  • Ball bearings of the turbine axle were newly adopted to reduce friction in the turbocharger. With the optimized ECU programming, the engine increases the maximum torque by 8 Nm, compared to the base WRX STI model, and it offers smoother and quicker response to the accelerator pedal and excellent accelerating performance.
  • An inter-cooler water spray prevents rise in intake-air temperature at continued high-load driving, providing stable engine performance and improved efficiency.

Enhancement of Chassis performance:

  • Reinforcement of the cross member in front-suspensions offers a linear steering response.
  • Rear LSD (Limited Slip Differential) system was changed to a mechanical type from a Torsen type to obtain the steady and powerful traction during cornering.
  • Bridgestone "POTENZA RE070" (245/40R18) were adopted to enhance cornering ability and higher grip performance, especially in dry conditions.
  • Nimble handling with a firm steering feel is assured by increasing oil flow volume in the power steering system.

Lightened body:

  • An aluminum engine hood and a downsized battery, which make the front section of the vehicle lighter, produce better maneuverability.
  • Laminar glasses were adopted in the front and side windows. They lightened the upper section of the body weight, resulting in improved stability during cornering.
  • Newly-designed lightweight 18-inches alloy wheels are standard to offer excellent road-hugging property by reducing unsprung weight.

Others:

  • A structural change of fuel pomp provides stable fuel delivery even on high-load driving.
  • Gold colored "brembo" brake calipers are standard.
  • The front bucket seats (fabric with red stitch) are standard on models with 18-inches alloy wheels.
  • The "RECARO" seats are optional with SRS front side airbags and SRS curtain airbags on models with 18-inches alloy wheels.

Major specifications:

  • Engine type: Horizontally-Opposed 4-cylinder DOHC 16-valve turbocharged engine
  • Displacement: 1,994 cc
  • Maximum output: 227kW (308 PS)/6,400 rpm
  • Maximum torque: 430 Nm (43.8 kgfm)/4,400 rpm
  • Turbo type: Ball-bearing type twin scroll turbocharger

I love the dashboard and steering wheels of this Impreza! It looks so awesome on that even with its center console. It’s a good thing either that they did some enhancement on its performance.

This seems to be very optimized and well elevated. Every parts emphasis and give importance to its unique look. Definitely, one of the modern tuned up car.

Well, I really don’t think that the due to its sporty look it will make the car to have an impressive speed performance. BTW, it’s a good thing that it offer a better fuel economy.

The speed performance of the Subaru Impreza WRX STI has an impressive power! Plus the styling is quite awesome.

I don’t have any background about Subaru, but I admit that it is having a luxurious design. And I also notice that the power of this car is not that great. Maybe, I should research for more information about Subaru.

I have to say the performance of the car is great though i have to say that it will be less considered since theirs other option rather than this.

Well, I don’t think the engine power of the car is impressive. It has a less power for a turbocharged tuner. I was expecting for more power!

Aesthetically, the car is impressive from its exterior modification to its luxurious interior. I like the styling for the rear lip and corner spoiler.

An inter-cooler water spray prevents rise in intake-air temperature at continued high-load driving, providing stable engine performance and improved efficiency.

It such a great thing to know that this is one of the best and very worthy car you can buy for,Why?it has a unique design and style that appears incredibly amazing.

In addition to the revised turbocharger and ECU, Subaru equips the Spec C with a mechanical rear limited-slip differential and the front chassis has been reinforced with a new cross member.

The front of the 2011 model is better than the pre-facelift version, but why didn’t Subaru put red tints on the taillights as standard? would have been even better.

The car’s twin scroll turbocharger gets newly adopted ball bearings for the turbine axle bearing, and the ECU program was also exclusively tuned.

As with all things ugly, they later grow on you! Better headlights. Still awaiting best ever interior ever seen in a Subaru! Maybe the sexy Scooby coupe can deliver? We’ll see.

I think I’ve already decided I’m buying new though...I’ve had one bad experience buying a sports car used, and that was enough to make me want to not do it again.

If it’s lighter and more responsive, thats effectively a horsepower increase, but even better because a it yields an increased power to weight ratio, even if only slightly. In this size car, midrange (usable) torque increase is just as important if not more, usually makes for a significant difference in driving experience.
