Seat was caught testing the next generation Leon on public roads again, only this time our spy photographers were able to spot a test car with less camouflage in broad daylight.

The fourth generation of Seat’s Ford Focus rival will adopt a curvier design language than its predecessor, a trend that started with the Tarraco SUV. In fact, the front end appears to get the same styling with Seat’s seven-seat SUV.

This translates into a more sculpted front end, prominent shoulder lines and a clean rear end that will feature Seat’s distinctive LED signature lighting.

The highlight of the next Seat Leon is expected to be found inside, as the Spanish car maker will be the first one to use VW’s latest infotainment technologies. The new system will come with over-the-air updates and feature a better user interface than before. Passengers will be able to control it through advanced voice control. The climate controls will also migrate in the new infotainment system, as the dashboard will feature fewer buttons and knobs than before.

The new Seat Leon will use an updated version of the MQB platform, which will be lighter thanks to the increased use of lightweight materials. The engine range will include VW’s upcoming mild-hybrid petrol powertrain that pairs the 1.5-liter TSI with a 48-volt electrical architecture. The new Leon will also become the first Seat with a plug-in hybrid powertrain, offering at least 31 miles (50km) of electric range. Diesel engine options will also be available.

Seat plans to offer the new Leon in five-door hatchback and wagon bodystyles, with the latter to also spawn a crossover-styled model with increased suspension travel and more rugged styling.

The new Leon is expect to debut in near-production form at the Geneva Motor Show next year.
