What’s Really Different Between a 2017 and 2020 Mercedes-AMG C43?

If you’re shopping for a used Mercedes-AMG C43, you’ve probably noticed a big price gap between the 2017 and 2020 models—often around $10,000. That’s a lot of money, and you’re right to wonder what you’re actually getting for it.

From the driver’s seat, the 2020 model feels a bit sharper. Mercedes updated the suspension tuning and steering calibration on the post-facelift cars, so turn-in is more immediate and the ride is slightly tauter, though still comfortable for daily driving. The 2020 also gets a revised nine-speed automatic that shifts quicker in Sport+ mode.

The 2017, while still a blast to drive, has a softer edge—it’s a little more relaxed, which some owners actually prefer.

Inside, the 2020 has the newer MBUX infotainment system with a larger touchscreen, voice control, and better smartphone integration. The 2017 uses the older COMAND system, which works fine but feels dated. Exterior styling is subjective, but the 2020 has a more aggressive front bumper and updated LED headlights.

Mechanically, both use the same twin-turbo V6 (362 hp in the 2017, 385 hp in the 2020), but the 2020’s power bump is modest. Neither is unreliable, but turbocharged Mercedes engines do require attentive oil changes and cooling system checks—especially in South Florida heat.
