Our spies have sent us the first batch of images with the 2016 SEAT Leon facelift while undergoing testing in Austrian Alps.

There's not much to talk about in terms of design as the prototype was wrapped around in full camouflage to hide what will likely be some subtle styling tweaks taking into account the current Leon still looks very fresh. What's really interesting about this car are those measuring devices mounted on the wheels along with a laptop inside the cabin which indicates the car likely has a new engine.

It is believed the engine in question is a new version of the four-cylinder 1.8 TSI equipped with active cylinder technology (ACT) that will make its debut on the facelifted A3 due next year. If that's the case, expect power to increase from the current 180 PS to 190 PS while fuel consumption will marginally decrease since the ACT system will shut down two of the cylinders during low loads when the full power is not needed.

It will be interesting to see whether the Volkswagen Group will install this engine on the SEAT Leon and Skoda Octavia facelifts or they will decided to put it only in the revised Golf and A3. All four cars are based on the MQB platform and will get a mid-cycle refresh next year, with the A3 likely leading the way, followed by the Golf, Leon and the Octavia.
