Tailoring Driving Dynamics: AMG DYNAMIC SELECT
The Benz C450 AMG 4MATIC offers a versatile driving experience, easily adaptable to driver preferences through the AMG DYNAMIC SELECT system. This system allows drivers to choose from various AMG-specific drive programs – “Eco,” “Comfort,” “Sport,” “Sport Plus,” and “Individual” – using a conveniently located switch to the left of the touchpad. Each mode adjusts the suspension, steering, and powertrain characteristics to deliver distinct driving experiences.

The “Sport Plus” program is engineered to maximize hallmark AMG dynamics and amplify the emotional driving experience. It features partial cylinder suppression during gear changes achieved by briefly retarding ignition and injection under full throttle. This not only speeds up gear shifts but also produces an audible and engaging experience. Complementing this are the emotionally resonant double-declutching function during downshifts and the distinctive “exhaust rumbling” in overrun mode. The robust engine sound, a hallmark of AMG vehicles, is a critical element of the C450 AMG’s character. To achieve this, engineers developed a new sports exhaust system that reduces back-pressure and weight, enhancing both performance and auditory appeal.
The accelerator pedal setup also dynamically adjusts with the AMG DYNAMIC SELECT settings. As the driver shifts from “Eco” towards “Sport Plus,” the throttle response of the twin-turbo V6 engine becomes increasingly immediate and dynamic. Even engine starts are designed to be emotionally engaging, especially in “Sport Plus” mode, where the engine speed momentarily jumps to 2000 rpm before settling to idle, providing an aural hint of the car’s performance potential. The chosen drive program setting is stored for up to four hours, ensuring a consistent driving character.
In contrast, the “Eco” program prioritizes fuel efficiency by integrating an ECO start/stop function and a sailing function. When the driver releases the accelerator at speeds between 37 and 99 mph, the transmission clutch disengages, decoupling the engine from the powertrain. The engine speed then drops to idle, minimizing driving resistance from compression and frictional forces during overrun.
7G-TRONIC PLUS Transmission: Precision and Responsiveness
The 7G-TRONIC PLUS automatic transmission in the Benz C450 AMG 4MATIC is engineered to deliver both refined composure and maximum spontaneity, depending on the selected drive program and driver input. In “Sport Plus” mode, it offers remarkably quick response times, executing gear changes with lightning speed and precision. This responsiveness is a result of leveraging hardware and software solutions from the Mercedes-AMG C 63. The ‘M’ button on the center console allows drivers to engage manual mode, fully exploiting the engine’s potent pulling power across its entire rev range. In manual mode, the 7G-TRONIC PLUS will not automatically upshift, even at redline or during kick-down; gear changes are solely controlled by the driver via steering-wheel paddle shifters.
The momentary ‘M’ mode offers a hybrid approach, combining the control of manual gear changes with the convenience of automatic upshifts and downshifts. Drivers can manually shift at any time using the paddle shifters, but if no manual input is detected, the transmission seamlessly reverts to automatic mode after a short period.
Enhancing refinement, the 7G-TRONIC PLUS transmission incorporates a dual-turbine torsional damper with a speed-sensitive centrifugal pendulum. This sophisticated component effectively minimizes vibrations, significantly improving passenger comfort.
AMG Adaptive Sports Suspension: Agility and Comfort
Agility and sportiness are central to the Benz C450 AMG 4MATIC, reflecting AMG’s decades of success in motorsports. The combination of permanent 4MATIC all-wheel drive and AMG Adaptive sports suspension is key to delivering this dynamic experience. The 3-stage damper adjustment system, also found in the Mercedes-AMG C 63, balances high agility with everyday usability.
The AMG Adaptive sports suspension features specially developed axle components with high aluminum content and electronically controlled shock absorbers with 3-stage adjustability. Drivers can select their preferred suspension setup at the touch of a button, ranging from comfortable for long journeys to maximally sporty for dynamic driving.

Technically, the suspension is characterized by a four-link front axle with special steering knuckles and load-bearing joints, all optimized for rigidity. Increased negative camber on both front and rear multi-link axles enhances lateral dynamics. Stiffening of the body shell improves steering response, cornering feedback, and reduces tire noise. The elastokinematics of both axles are designed to be more rigid overall, improving precision, agility, and dynamics. This results in reduced body roll, higher lateral acceleration, enhanced traction, and neutral handling at the limit. Optimized pull-rods and front-axle carrier mounts ensure that the C450 AMG retains Mercedes-Benz’s renowned long-distance comfort.
Performance-Oriented 4MATIC All-Wheel Drive
The 4MATIC all-wheel-drive system in the Benz C450 AMG 4MATIC, shared with other AMG high-performance models, provides optimal traction, effectively preventing wheel slip during acceleration.

This rear-biased torque split enhances agility around the vehicle’s vertical axis. The ESP® system with Curve Dynamic Assist is also sportier in its calibration, further enhancing lateral dynamics and cornering performance for enthusiastic drivers.
Steering and Braking Systems for Dynamic Control
The electro-mechanical speed-sensitive sports steering in the C450 AMG supports precise tracking and a dynamic driving style. Its direct and consistent AMG-specific steering ratio, along with optimized tuning and response, contributes to agile handling. Steering force is electronically adjusted based on vehicle speed, and steering characteristics adapt with the selected drive program. “Sport” and “Sport Plus” modes provide a firmer, sportier steering feel, while “Eco” or “Comfort” modes offer a more relaxed steering experience. The “Individual” program allows further customization, enabling drivers to combine sporty steering with comfortable suspension, or vice versa.
