2023 Mercedes-Benz C43 AMG

With technology derived directly from Formula 1, the latest generation of the Mercedes-AMG C43 4MATIC sets new standards for innovative drive solutions both as a Saloon and as an Estate. Following its premiere in the Mercedes-AMG SL43, the AMG 2.0-litre four-cylinder engine, the world's first series-production unit to feature an electric exhaust gas turbocharger, is now also being used in the C-Class. The new form of turbocharging guarantees particularly spontaneous response across the entire rev range and thus offers an even more dynamic driving experience. The turbocharger is operated via the 48-volt electrical system, which also feeds the belt-driven starter-generator (RSG). In the Mercedes-AMG C43 4MATIC the unit produces 300 kW (408 hp) and, in certain driving situations, is able to call upon a brief additional boost of 10 kW (14 hp) from the RSG.

The standard rear-axle steering, the AMG Performance 4MATIC permanent all-wheel drive with rear-biased torque distribution, the AMG SPEEDSHIFT MCT 9G transmission with wet start-off clutch and the AMG RIDE CONTROL suspension with Adaptive Damping System also contribute to the dynamic driving experience. In keeping with this, brand-specific features in the equipment and appointments as well as in the exterior and interior design emphasise the performance-oriented character of the new Mercedes-AMG C43 4MATIC. The internally named M139l engine (l for longitudinal installation) is the world's first series-production engine to be turbocharged with an electric exhaust gas turbocharger. The innovative system is a direct derivative of the technology that the Mercedes-AMG Petronas F1 Team has been using so successfully in the premier class of motorsport for many years. The new form of turbocharging guarantees particularly spontaneous response across the entire rev range. This leads to an even more dynamic driving experience, while at the same time increasing efficiency.

The functional principle of the electric exhaust gas turbocharger in detail


An electric motor around four centimetres thin is integrated directly on the turbocharger shaft between the turbine wheel on the exhaust side and the compressor wheel on the intake side. Electronically controlled, this drives the shaft of the turbocharger directly and thus accelerates the compressor wheel, before the exhaust gas flow takes over the drive in the conventional way. This significantly improves the response directly from idle speed and across the entire rev range. The combustion engine responds even more spontaneously to accelerator pedal input, while the entire driving feel is significantly more dynamic. In addition, the electrification of the turbocharger enables higher torque at low revs. This also increases agility and optimises acceleration from a standstill. Even when the driver takes his foot off the accelerator or brakes, the technology is able to maintain boost pressure at all times, so ensuring a continuously direct response.

300 kW (408 hp) and 500 Nm enable sporty driving performance


In the 2.0-litre four-cylinder in-line engine, innovative technology helps the Mercedes-AMG C43 4MATIC to achieve a rated output of 300 kW (408 hp) at 6750 rpm. The maximum torque of 500 Nm is available at 5000 rpm. Depending on the situation, the system also briefly provides an additional boost of 10 kW (14 hp) through the belt-driven starter generator (RSG). The second-generation RSG acts as a mild hybrid, providing this temporary power boost as well as functions such as gliding and recuperation for maximum efficiency. At the same time, the 48-volt technology also increases comfort, as the transitions between the start-stop function and the gliding mode function are almost imperceptible. The C43 4MATIC Saloon accelerates from a standstill to 100 km/h in just 4.6 seconds, while the C43 Estate takes only slightly longer for the same exercise, at 4.7 seconds. The top speed is electronically limited at 250 km/h in both models. By adding the optional AMG Driver's Package, it can be raised to 265 km/h in each case. The great efficiency potential of the innovative turbo technology is revealed by the combined consumption figures according to WLTP of 9.1-8.7 l/100 km for the Saloon and 9.2-8.8 l/100 km for the Estate.

AMG DYNAMICS standard component of the AMG DYNAMIC SELECT drive program selection


The five AMG DYNAMIC SELECT drive programs "Slippery", "Comfort", "Sport", "Sport +" and "Individual" permit a wide range of vehicle characteristics, from comfortable to dynamic. The distinct driving modes offer an individual driving experience, precisely tailored to different driving conditions. In the "Sport" and "Sport+" programs, the engine's responsiveness, the transmission's shifting behaviour and the suspension and steering are tuned to be particularly agile. The C43 4MATIC also features the integrated "AMG DYNAMICS" driving dynamic control system as a component of the AMG DYNAMIC SELECT drive programs. This enhances the stabilising functions of the Electronic Stability Program ESP® with interventions to add agility to the steering characteristics and additional ESP® functions. When cornering at speed, for example, brief braking intervention at the inner rear wheel generates a defined yawing moment around the vertical axis for responsive and precise turn-in. The extent and effectiveness of these interventions depend on the AMG DYNAMIC SELECT program selected, whereby drivers using "Individual" mode can determine the settings for the AMG DYNAMICS levels "Basic", "Advanced" and "Pro" for themselves. The ESP® can be adjusted in three stages. "On" is the standard selection that offers high safety, adapted to the sporty character of the overall vehicle. "Sport", on the other hand, allows higher drift angles, while "Off" allows the system to be switched off completely for a particularly sporty driving style on closed-off race tracks.
