Next-generation Leon spied testing in the European night showing more of its shape and rear light clusters.

We haven't seen any 2012/2013 Seat Leon prototypes in a while but the last time they were spied it was at night too.

This time we get a better sense of the shape of the car and a good look at the rear taillight clusters as they're lit up during the night time testing run somewhere in Europe.

The 2012/2013 Seat Leon will share a platform with the next-generation Audi A3 and the Golf VII, due next year and built on VW's new MQB platform ("Modular Querbaukasten" in German).

We expect the Leon to also share power plants with the new Golf (Mk VII).
