The bulk of the changes here are in the cosmetic flourishes for the interior as well as some more performance upgrades. And of course, there's the supped-up engine with added horsepower and torque.

Which Trim To Choose?

When deciding which model to buy, the first choice will be between the sedan and coupe versions of the 2021 Mercedes C-Class. If the buyer plans on having passengers on a regular basis, the sedan is probably the better choice. Single drivers may prefer the looks of the coupe, but the sedan is more practical.

Different drivers will have a different opinion on which trim is the best depending on what their priorities are. For most drivers, the C 300 4Matic will be the best option. It's only a slight price increase over the base trim. The 4Matic AWD is more than worth that modest price increase. The upgrade in traction and handling is significant, and buyers still get all of the features of the C 300.

For the performance-minded buyers, they will no doubt prefer one of the AMG models. The AMG C 63 is the best option here. While it doesn't reach the horsepower of the AMG C 63 S, it still cranks out 469 hp and 479 lb-ft of torque. That should be plenty enough for thrill seekers while remaining less expensive than the AMG C 63 S.
