2013 Subaru WRX STI Spec C four-door released in Japan
Subaru has announced that the 2013 WRX STI will add the competition version Spec C to the four door variant. The "A-Line type S Package" was also introduced in both the 4-door and 5-door models. But before you get too excited, the new lighter, more powerful Subaru WRX STI models will only be available in Japan.
If you feel like the red-headed step child, you are not alone. The new variants would certainly be a hit here in the U.S. The Subaru WRX STI has been a big success here in North America and has a loyal following. The Japan versions arrived in Japanese showrooms earlier this week. But for now, all we can do is wait.
The new four-door Spec C will also be getting some other fun upgrades. WRX STI models will feature new items such as the newly designed 18-inch aluminum wheels. And Recaro performance seats are offered as an option. The "A-Line type S Package", a special edition introduced last year, was also introduced in both four-door and five-door models. The "A-Line" also uses a 2.5 liter Horizontally-Opposed Boxer turbo engine and 5-speed automatic transmission.
The competition Spec C is faster and lighter
The Spec C was first introduced in Japan as a 5-door model in December 2010. The four-door introduced this week will enjoy the same high-performance engine as the five-door model. And it goes beyond just more power under the hood. Subaru also increased performance by reducing weight and tweaking the suspension. The Spec C body is lightened by small but significant changes with an aluminum hood, lighter window glass and a smaller battery.
Upgrades over the standard WRX STI are substantial. Subaru first of all made adjustments to the ECU and then fitted a special ball-bearing-type twin-scroll turbocharger for added torque and quicker acceleration. Horsepower remains the same at 304 as the standard STI, but torque was increased from 311 on the turbocharged, 2.0-liter horizontally opposed four-cylinder engine to 317 lb. ft. on the Spec C. A six-speed manual gearbox is mated to the high-performance boxer engine. The Spec C also gets a rear limited-slip differential that is mechanical rather than a Torsen-type.
