AN UPDATED Mercedes-AMG C43 sedan with more power, revised styling and a heavily overhauled interior has been revealed on the eve of its reveal at the 2018 Geneva Motor Show.

Both the C43 sedan and estate body styles will inherit a round of upgrades including a 17kW power bump for the 3.0-litre twin-turbo V6 engine that lifts outputs to 287kW and 520Nm via the fitment of the Mercedes E43’s larger turbos.

Multi-beam LED headlights that can shut off individual sections of the beam to avoid dazzling other drivers are offered as standard equipment and, like the E-Class, now feature 84 individual LED chips for greater light output.

An aggressive, gloss black diffuser incorporating a quartet of exhaust tips is added to the rear as part of a fresh bumper design. An AMG representative said a decision was made to give the C43 its own distinctive appearance rather than the same bumpers as other C-Class models fitted with the AMG Line styling kit.

Interior upgrades include the introduction of AMG’s new Performance steering wheel, and heated and cooled electric-adjust front seats taken from the AMG GTC Roadster.

The C43 is the first C-Class-based AMG product to be shown since the regular series model’s facelift was announced. That makeover brought a raft of improvements to the car’s interior, which also feature here, including a fully digital dashboard designed to fit within the regular instrument cluster outline rather than the tablet-style screens seen in E-Class, S-Class and the impending A-Class models.
