New Peugeot 408: 2026 update set to bring new styling and technology

Three years have passed since the Peugeot 408 arrived. Some regard it as an SUV and others as a saloon, but it is actually a blend of both: a crossover saloon or, if you prefer, a Peugeot 308 with “its trousers rolled up”.

Whatever label is applied, the French model is beginning to show its age. To ensure it remains aligned with the brand’s other offerings, it will be updated for 2026, strengthening the qualities that have helped it maintain healthy sales.

Although no official details have yet been released, it is not difficult to predict that the revised 408 will adopt the same changes introduced on the new Peugeot 308, unveiled just over a month ago.

New Peugeot 408 exterior and interior

Starting with the styling, camouflage on the prototypes we have spotted supports that expectation. The Peugeot 408 is set to gain a new front end and, like its “sibling”, it should chiefly feature split headlights and a fresh lighting signature defined by LED “three claws”.

These “three claws” will sit at the top of the front section and are also expected to be joined by illuminated strips stretching across the vehicle, covering virtually the full width of the bodywork. The brand logo in the centre of the grille should be illuminated too.

Inside, the new Peugeot 408 is expected to follow the brand’s technological development. The i-Cockpit will remain the focal point, now with new features ranging from customisable ambient lighting to a redesigned instrument panel.

The most significant new feature, however, could be the introduction of the i-Connect Advanced infotainment system, incorporating TomTom navigation and ChatGPT integration.

Peugeot 408 engines

What is under the bonnet?

As for powertrains, the 408 is likely to retain one of the broadest ranges in its segment, with petrol, Diesel, plug-in hybrid and fully electric options.

The petrol offering should be limited to the 1.2 Turbo engine, now paired with a 48 V mild-hybrid system producing 145 hp and 230 Nm. Meanwhile, the Diesel version is expected to remain with the 130 hp 1.5 BlueHDi engine.

However, if electric range is the priority, the plug-in hybrid system or the fully electric version should be the preferred choice. The former is expected to deliver combined maximum output of around 195 hp and a maximum electric range close to 84 km (WLTP), courtesy of a 17.2 kWh battery.

The latter should use a 157 kW (213 hp) electric motor, supplied by a 58.2 kWh battery that should provide a range of up to 452 km (WLTP).

When will it arrive?

Peugeot has not yet officially commented on the arrival of the updated Peugeot 408, but all indications suggest it will be unveiled later this year before reaching the market next year.
