Power from the twin-turbo V-8 stays the same

When Mercedes showed off the refreshed C 300 earlier this year, we knew it was only a matter of time before the AMG versions also got an update. The C 43 showed up first, gaining an additional 23 hp and an improved aero kit. Now, with the New York auto show in full swing, it’s the C 63’s turn.

As far as design changes go, the C 63 gets a new grille and a reworked bumper with new air intakes. Out back, there’s a new quad exhaust and diffuser, while the shape of the rear bumper has been changed to improve airflow. For an even sportier look, you can also now add an aerodynamics package to the C 63 coupe.

Inside, Mercedes offers a few new leather and trim options, as well as the option to add ventilation to its AMG sports seats. More importantly, the C 63 gets a wider 12.3-inch infotainment system and a new AMG steering wheel with Mercedes’ ultra-cool Touch Control Buttons.

Unlike the rest of the 2019 C-Class lineup, the updated C 63 doesn’t get any additional power. Still, there’s a chance both the C 63 and C 63 S will be slightly quicker thanks to a new nine-speed wet-clutch transmission. Not only does the nine-speed get two more gears than the outgoing unit, Mercedes says it’s smoother and shifts quicker. Hopefully, that applies in all situations, not just at wide-open throttle as we observed in the 2017 model. AMG says it also recalibrated the C 63’s driving modes to further improve the driving experience.
