The future generation 2014 Subaru Impreza WRX STI was recently spied on public roads. Even though the 2014 Impreza WRX STI prototype is completely covered in camouflage, it's obvious it has a new front fascia and a redesigned rear end. The 2014 WRX STI is going to have a four-door sedan body type. It will come with re-designed headlights and rear lights, a four tailpipe exhaust system and a huge rear spoiler. To get a picture of how the new WRX STI (2014) is going to look like, you may refer to the WRX Concept unveiled back in March this year. The power of the new 2014 Subaru Impreza WRX STI is going to come from either a turbocharged 2.0-liter engine, or a 2.5-liter turbo unit. Even though it hasn't been confirmed yet, we're pretty sure the 2014 STI is going to continue the AWD tradition of the model.
