A mule of the next generation Subaru Impreza has been spied testing a new engine in southern Europe.

A mule of the next generation Subaru Impreza has been spied testing a new engine in southern Europe.

According to our spy photographers, the white Impreza hatchback spotted here was being driven very slowly due to the visible added hardware connected to the exhaust system. On the inside it had a lot of testing equipment which can only mean Subaru still has a lot on its plate in terms of development.

The next Impreza is believed to be the first model to ride on an all new architecture called Subaru Global Platform (SGP). We already know from the company's chief designer Mamoru Ishii the styling will be influenced by the attractive WRX concept and it will carry over most of the proportions.

The all-new Impreza is set to go on sale as a 2016 model year so chances are an official reveal will occur in the second half of next year.
