Germany's favourite family estate is due to receive a mid-life refresh.

European customers have been enjoying a smart and more refined Volkswagen Passat for years now and it’s actually going to be refreshed in just a couple of months from now. Today we are taking a look at another test prototype to see what’s in the cards for the D-segment model.

We’ve already seen Volkswagen testing the Passat sedan and GTE, and this is the first time the German company is taking out an estate trial car on tests. Don’t expect any drastic visual changes, especially at the back where the only revisions will probably be limited to new graphics for the LED taillights and a slightly reshaped bumper.

Up front, Volkswagen will probably give the 2019 Euro-spec Passat a fascia inspired by the Arteon, which means we will be dealing with a more pronounced radiator grille. Below the grille, the Passat will likely get slightly bigger air intakes in the bumper.

The same conservative approach will be taken with the interior as well, where the most important novelty should be an improved infotainment system. Don't hold your breath for the tech-heavy Innovision Cockpit of the 2019 Touareg though, as that would basically require a completely new dashboard and changes to the electrical architecture.

Details about the engine range are limited, but it’s probably safe to assume the outdated 1.4-litre TSI will be replaced by the new 1.5-litre TSI. The wildest speculations even put a turbocharged V6 under the bonnet of a range-topping Passat R, but we are still taking these rumours with a grain of salt. On the other side of the spectrum, the Passat GTE plug-in hybrid should get a longer pure electric range.
