Starting with 2017, the SEAT Leon lineup was increased with the addition of new family members as part of the car's third generation mid-cycle facelift. Alongside the regular 5-door hatchback, SEAT saw fit to begin offering various other body versions, like the ST station wagon, ST X-Perience crossover and SC 3-door hatchback. By far the sportiest-looking version, the Leon SC (Sports Coupe) is a classic take on the hot-hatch look thanks to its vastly different exterior design compared to the 5-door version.

Since the first generation, the SEAT Leon was available only as a 5-door hatchback. But that was changed in 2013, with the introduction of the 3-door version.
