Good news: it's wider. Bad news: it's still a tablet-style unit.

Having been spotted a week ago with barely any camouflage (see spy photos below), it means the official reveal of the 2018 Mercedes C-Class is likely right around the corner. Rumored to debut in January 2018 at the North American International Auto Show in Detroit, the mid-cycle refresh for the premium sedan will bring an assortment of changes both inside and out.

Update:

For starters, this prototype was caught by the spy camera in Germany the other day undergoing final testing while failing to hide its new Comand infotainment system with a wider display. Fans of the three-pointed star badge will remember this setup as it has already been previewed by Mercedes through the near-production GLC F-Cell introduced earlier this year at the Frankfurt Motor Show.

The biggest screen available in the outgoing C-Class measures 8.4 inches in diagonal whereas the one in the aforementioned hydrogen-powered crossover has a 10.25-inch size. The sedan is also expected to inherit the new multifunction touchpad with handwriting recognition. While this test vehicle had analog dials for the instrument cluster, there’s a good chance the 2018 C-Class will be optionally available with a fully digital 12.3-inch setup as seen in the GLC F-Cell we’ve been mentioning.

Stepping outside of the vehicle, you will notice the cap on the rear bumper revealing the prototype in question was the thrifty C350 plug-in hybrid. There are going to be updated graphics for the all-LED taillights, along with new Multibeam LED headlights derived from those of the bigger E-Class. Underneath the hood, Mercedes could install its new OM 654 four-cylinder turbodiesel engine borrowed from the E.

Following the sedan’s premiere in January, the wagon will likely be unveiled a couple of months later in Geneva and should be shortly followed by the coupe and cabriolet.
