Revolutionizing Performance: The 2024 Mercedes-AMG C 43 4MATIC and Its Electric Turbocharger

The Mercedes-AMG C 43 4MATIC, incorporating groundbreaking technology from Formula 1, epitomizes the fusion of power and advanced technological innovation. This model is distinguished by the world's first series-production 2.0-litre four-cylinder engine with an electric exhaust gas turbocharger. This pioneering turbocharging approach ensures a responsive performance across the entire rev range, enhancing the driving dynamics.

The engine, capable of delivering 402 hp and an additional 13 hp boost in certain scenarios, benefits from the integration of a 48-volt electrical system. This system powers the belt-driven starter-generator (BSG). Key features contributing to the vehicle's dynamic performance include standard rear-axle steering, AMG Performance 4MATIC all-wheel drive with a rear-biased torque distribution, the AMG SPEEDSHIFT MCT 9G transmission, and the AMG RIDE CONTROL suspension with Adaptive Damping System. These elements, along with specific design features, underscore the performance-oriented character of the C 43 4MATIC.

Philipp Schiemer, Chairman of the Board of Management of Mercedes AMG GmbH, highlights the model's success and the role of the electric exhaust gas turbocharger in enhancing both driving dynamics and efficiency. He emphasizes the potential of electrified combustion engines in this context.

Central to the C 43 4MATIC is the AMG 2.0-litre four-cylinder engine, developed and manufactured in Affalterbach under the "One Man, One Engine" principle. This engine, known as M139l (l for longitudinal installation), stands out as the first series-production engine to use an electric exhaust gas turbocharger. This technology, a derivative from the Mercedes-AMG Petronas F1 Team, ensures a responsive and dynamic driving experience, along with improved efficiency.

The electric exhaust gas turbocharger, powered by the 48-volt system, operates at speeds up to 175,000 rpm, maintaining boost pressure consistently for immediate response. The closed-deck design of the engine, derived from motorsport technology, allows for peak combustion pressures over 2,300 psi. The NANOSLIDE technology, used in the linings, minimizes friction and enhances durability. The engine also features a two-stage fuel injection system and a sophisticated cooling system for optimal performance and efficiency.

The Mercedes-AMG C 43 4MATIC produces 402 hp and 369 lb-ft of torque, with an additional 13 hp boost from the BSG. The AMG SPEEDSHIFT MCT 9G transmission, featuring a wet start-off clutch, ensures quick response and efficient power delivery. The permanent AMG Performance 4MATIC all-wheel drive provides a dynamic driving experience with a rear-biased torque distribution.

The AMG DYNAMICS system, part of the AMG DYNAMIC SELECT drive programs, adjusts the vehicle's dynamics based on the selected mode. The rear-axle steering, a standard feature, enhances agility and maneuverability at various speeds. The AMG RIDE CONTROL suspension with Adaptive Damping System offers a balance between sporty driving and comfort.

Externally and internally, the C 43 4MATIC boasts distinctive AMG elements, including the AMG-specific radiator grille, sporty design cues, and high-quality materials in the cabin. The MBUX infotainment system offers AMG-specific displays and functions, enhancing the driving experience.

In summary, the new Mercedes-AMG C 43 4MATIC represents a significant step forward in combining high performance with advanced technology, offering a dynamic and efficient driving experience.
