Seat has been busy working on the next-generation Leon, the Spanish cousin of the VW Golf, with our spies able to capture a test car during some cold-weather development.

The fourth generation of the Seat Leon will be based on the upgraded MQB platform, meaning that it will be lighter as well as compatible with the upcoming mild-hybrid and plug-in hybrid 48-volt powertrains that VW Group is currently working on.

The engine range will still include conventional petrol and diesel options, as well as the new mild-hybrid 1.5-liter TSI and a plug-in hybrid version with at least 31 miles (50km) of pure electric driving range.

Despite the full-body camouflage, the design of the new Leon will stay on the same path that started with the Tarraco SUV. This means that the front end will feature Seat’s new, curvier visual identity that includes an aggressive face, prominent shoulder lines and a characteristic LED lighting signature.

Seat has said in the past that one of the highlights of the new Leon will be found inside, and more specifically on its new infotainment system; the Spanish brand and the new Leon will be the first inside the VW Group to use an all-new system that will feature over-the-air updates, an advanced voice recognition system and a wide high-def touchscreen display.

The 2020 Seat Leon will arrive in the market in just two bodystyles: a five-door hatchback and a wagon. Seat took the decision to ditch the three-door hatchback from the range for quite some time now. Additional models will include the hot Cupra version and possibly a crossover-styled wagon with more suspension travel and extra body cladding.

Seat is expected to reveal the new Leon in the next few months, so stay tuned.
