The pictures were posted by Instagram user CochesPias, and show the front and rear ends of the Ford Focus rival fully unwrapped. Visible details include an angular front grille design mirroring that of the firm's large Tarraco SUV, and the horizontal rear light bar shown in official preview images released by Seat.

Seat hasn’t been shy of dropping teasers of the new Leon ahead of its unveiling. In December it released a video showing details of the model, and recently gave us a look at the upcoming car’s rear in a new image. Seat insiders have called the new car the biggest step forward in the model's history, with a significant improvement in cabin technology and the introduction of variants with electrified powertrains.

The new car gains a full-length lighting strip across the tailgate that echoes that of Seat's El Born EV, a new design of rear name badge than on the outgoing car and the return of full LED headlights. The new Leon is also set to gain ambient lighting features in the cabin.

Despite claims of a radical new design direction beginning with the Mk4 Leon, prototypes feature an evolutionary look. Seat is gradually moving away from straight edges and sharp angles for future models, and this mule's curvier front-end demonstrates that.

The C-segment car will get a more advanced infotainment system - which can update maps, apps and functionality over the air - similar to that offered in the Mk8 Volkswagen Golf. Seat CEO Luca de Meo said: “For two years, we have been working on what will be the best infotainment system coming to market next year, starting with the Leon."
