Subaru revealed today a vehicle we all waited: Impreza WRX STI spec C! The new vehicle, which is available in two exclusive colors Sunrise Yellow and Pure White , is based on the standard Impreza WRX STI and features enhanced engine and chassis performance but also a lighter body on the premise of driving in motor sports.
Under the hood, the vehicle comes with the impressive horizontally-opposed 4-cylinder DOHC 16-valve turbocharged engine capable to develop 308 hp @ 6,400 rpm and 442 Nm of torque. Inside we find the Recaro sport buckets which come as an option to the models with 18-inches alloy wheels.
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 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.
- Specification changes in damping force of suspensions, coil spring rate, rear stabilizer and rear sub-frame bushes optimize rigidity for body roll and retain excellent road-holding capability.
- 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. (17-inches alloy wheels are optional)
- A flat tire repair kit is standard, which also helps weight reduction.
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 (Alcantara and leather combination with red stitch) are optional on models with 18-inches alloy wheels.
- Two exclusive exterior colors are available; Sunrise Yellow and Pure White.
- The production is limited to 900 units.
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: 422 Nm (43.0 kgf·m)/4,400 rpm
- Turbo type: Ball-bearing type twin scroll turbocharger
