After giving us a look at the interior of the 2018 Mercedes-Benz A-Class, the German carmaker has now dropped a video of the hatchback undergoing winter testing. The teaser doesn’t include a launch date, although it did state that the model is “coming soon.”

As you can see in the 36- second clip, prototypes of the new A-Class (reportedly codenamed W177) are subjected to sub-zero temperatures to ensure everything works as it should. The visual cues are largely similar to what we’ve seen in previous prototypes, where there’s a sleeker body, sharper headlights and a return to C-shaped graphics for the taillights.

Mercedes-Benz says the new A-Class will arrive after more than four years of development and testing, including this escapade in Sweden. The video description also reads, “these challenging testing cycles focus on the vehicle as a whole as well as the new engines,” with the last bit being of interest.

Rumours of a plug-in hybrid version of the W177 have been around for some time, and a prototype was even sighted not too long ago. The standard array of petrol and diesel engines from the brand will likely be featured on the new A-Class as well.
