2.0L M139 AMG Performance Hybrid - AMG GLC 63 S E PERFORMANCE
Plug-in Hybrid
Test drive task: Perform a low-speed stop-start sequence. | Description: Notice if the transition between the electric motor and the combustion engine feels jarring. While these hybrid systems are high-tech, complex integration can occasionally feel hesitant, so ensure the engagement feels smooth to your preference.
Check this by: Cycling through all Drive Modes. | Description: Engage the 'Race' and 'Battery Hold' modes to ensure the electronic dampers and exhaust valves react promptly. It's helpful to confirm that the AMG Dynamic Select system doesn't show any error messages on the dash.
While driving: Listen for any resonance during regenerative braking. | Description: The complex brake-by-wire system is sophisticated, but it is wise to ensure there are no unusual mechanical clicking sounds when transitioning from energy recuperation to traditional friction braking.
Check this by: Inspecting the coolant reservoir levels. | Description: Given the high-performance cooling requirements of the M139 engine and the electric drive unit, verify the coolant levels are stable. Always inspect the engine bay when the car is cold to ensure there are no signs of leaks.
Initial oil and filter service, check of the hybrid battery cooling system integrity.
Spark plug inspection and potential replacement, transmission fluid service check.
Major component inspection, potentially including brake fluid and heavy-duty drivetrain components.
Stick to the strict AMG-specific service schedule; skipping intervals can impact the complex warranty and performance.
Keep a close eye on the front and rear differential oils, especially if the vehicle is used for spirited driving.
Regularly clean the camera and sensor arrays to ensure the advanced driver assistance systems perform reliably.
Use only high-octane (98 RON) fuel to ensure the high-compression M139 engine operates at peak efficiency.
Ensure the 12V auxiliary battery is checked, as hybrid systems rely heavily on electrical health for cold starts and system stability.
Estimated repair costs if issues arise
Because this vehicle is a heavy performance hybrid, it puts significant demand on the braking system. Depending on your driving style, you might eventually need to budget for premium AMG-spec rotors and pads.
While the battery is designed for a long lifespan, it is common to consider professional diagnostics at authorized centers to ensure cell balance remains optimal as the vehicle ages.
The adaptive damping system is a marvel of engineering, but in cars of this performance caliber, it's wise to set aside funds for eventual air strut or sensor maintenance as the vehicle approaches higher mileage.
