Subaru Separates the Impreza from WRX, STI Versions

The next generation Subaru WRX and STI will be completely different from the current Impreza model, as the Japanese automaker intends to separate the sport versions from the standard model, according to Car Advice.

As soon as production resumes at the Japanese factories, the 2012 Impreza standard model, which represents the fourth generation of the car, will be available on the market alongside the third generation WRX and STI versions.

One reason for this separation may be the fact that the all new 2.0-liter boxer engine that is currently fitted on the new Subaru Impreza is not turborcharged, nor will it be, as the Japanese automaker has no plans to develop it. The move to dissociate the sport models from the rest of the field probably represents a marketing plan in order to create a self-contained and independent sports range.

The new 2.0-liter boxer unit in the 2012 Impreza is a normal aspirated engine designed to meet the ever increasing fuel efficiency figures.

The 2011 Subaru Impreza WRX STI is currently fitted with a 2.5-liter DOHC intercooled, turbocharged unit, capable of producing 305 hp. The engine has 4-cylinders horizontally opposed with 4-valve per cylinder and features the Dual Active Valve Control System (DAVCS).

This powerplant will continue to serve the WRX STI for years to come until Subaru finds a replacement. The Japanese maker also has plans to develop a hybrid version of the Impreza in the near future, so it might take a while until a new WRX STI version makes its debut.
