Spy Photos of the 2021 Mercedes-Benz C-class

There will be a suite of semi-autonomous driving functions, like what debuted on the facelifted current C-class, and if lawmakers are ready, the next C-class could offer autonomous driving up to Level 4.

The engine portfolio will consist of inline-four and straight-six engines—meaning no more V-6—including diesel powertrains.

All models will feature 48-volt mild hybridization, like the new CLS, with the exception of the plug-in hybrid models; we expect to see both diesel and gasoline plug-in hybrids, with a fully electric range of up to 60 miles.

A three-cylinder engine is out of the question, and there will likely be no more engines from the powertrain alliance with Renault-Nissan.

The top-of-the-line Mercedes-AMG C63 version should stay powered by a twin-turbo 4.0-liter V-8, with the lesser AMG variant using the a pumped-up version of the turbocharged straight-six.

The new C-class sedan will benefit from a significantly larger cabin and trunk.

Don't hold your breath for the diesel models to make their way to the United States.

Slated for a late 2020 or early 2021 calendar year launch, we expect the next C-class to be offered in the U.S. as a 2021 model year vehicle.

Competition will include the BMW 3-series and the Audi A4, and prices should remain close to the current model.
