Mercedes-Benz X290 AMG GT 4-Door Coupe: A Comprehensive Guide
The Mercedes-Benz X290, commercially known as the AMG GT 4-Door Coupe, is a high-performance luxury four-door coupe that blends the sporty DNA of AMG with the practicality of a sedan. Introduced as a concept at the 2017 Geneva Motor Show, the production version was revealed later that year, and sales began in 2018 as a 2019 model year. It represents a significant step for Mercedes-AMG, expanding their dedicated model lineup beyond the two-door GT and offering a direct competitor to the Porsche Panamera and Audi RS7.
Generations
The AMG GT 4-Door Coupe has essentially had one generation thus far. However, within this generation, there have been variations and updates. Here's a breakdown:
- X290 (2019 - Present): The initial model launched with various engine options, including the 53, 63, and 63 S variants.
- Key Changes (Ongoing): While a full generation change hasn't occurred, Mercedes-AMG consistently refines the X290. Updates have included:
- Model Year Updates: Minor tweaks to interior materials, exterior styling (bumpers, wheel designs), and technology features are common with each model year.
- Introduction of Hybrid Models: Later in the production run, AMG introduced plug-in hybrid variants with the "e Performance" designation, combining high-performance engines with electric motors for increased power and efficiency.
- Software Updates: Regular updates to the MBUX infotainment system and driver-assistance features.
Reliability & Common Issues
The AMG GT 4-Door Coupe, while boasting impressive performance, has its share of potential issues to be aware of. Due to its complexity and high-performance nature, maintenance can be more expensive than a standard Mercedes-Benz.
Engine Issues:
- M256 (53 Models): The inline-6 engine with EQ Boost is generally reliable, but potential issues can arise with the 48V electrical system (related to the EQ Boost mild-hybrid functionality). These can manifest as electrical glitches or charging problems. Check for recalls and ensure software is up-to-date.
- M177/M178 (63/63 S Models): The hand-built 4.0L twin-turbo V8 is a powerhouse, but requires diligent maintenance. Potential concerns include:
- Turbocharger Issues: Early models, in particular, had some reports of turbocharger failures. Look for signs of excessive oil consumption, unusual noises, or a loss of power. Inspect turbocharger oil lines for leaks.
- Oil Leaks: V8 engines, especially those highly stressed, can be prone to oil leaks. Common areas include valve covers, oil pan gasket, and turbocharger oil lines. Pre-purchase inspections by a qualified mechanic are crucial.
- Carbon Buildup (Direct Injection): Like all direct-injection engines, carbon buildup on the intake valves is a potential issue. Consider periodic cleaning (e.g., walnut blasting) to maintain optimal performance.
- Cooling System: High-performance engines generate a lot of heat. Ensure the cooling system is in good working order. Check for leaks, proper coolant levels, and fan operation. Overheating can lead to significant engine damage.
Transmission & Drivetrain:
- AMG SPEEDSHIFT MCT 9-Speed Transmission: This transmission is generally robust, but ensure it shifts smoothly and without hesitation. Look for any signs of slippage or harsh engagement. Fluid changes are crucial for longevity.
- 4MATIC+ All-Wheel Drive: The all-wheel-drive system is sophisticated and requires regular maintenance. Check for leaks from the transfer case and differentials. Listen for any unusual noises from the drivetrain during operation.
Suspension & Brakes:
- Air Suspension: Many AMG GT 4-Door models are equipped with air suspension. This system provides a comfortable ride and adjustable ride height. However, air suspension components (air struts, compressor) can be prone to failure over time. Listen for hissing sounds (indicating leaks) and check for sagging.
- Ceramic Composite Brakes (Optional): If equipped with ceramic composite brakes, be aware that replacing them is extremely expensive. Inspect the brake rotors for wear and tear. Cracks are normal, but excessive chipping or damage indicates the need for replacement.
Electronics & Interior:
- MBUX Infotainment System: Ensure all features of the MBUX system are working correctly, including the navigation, voice control, and connectivity features. Software glitches can occur.
- Driver-Assistance Systems: Test all driver-assistance systems (e.g., adaptive cruise control, lane-keeping assist, blind-spot monitoring) to ensure they are functioning properly.
- Interior Trim and Upholstery: Inspect the interior trim and upholstery for wear and tear. High-quality materials are used, but leather can crack or fade over time.
Driving Experience
The AMG GT 4-Door Coupe offers a thrilling and luxurious driving experience. It's a car that can be both a comfortable daily driver and a potent track weapon, depending on the configuration and driving mode selected.
Pros:
- Exceptional Performance: The powerful engines provide blistering acceleration and impressive top speeds. The handling is sharp and responsive, thanks to the well-tuned suspension and advanced all-wheel-drive system.
- Luxurious Interior: The interior is beautifully crafted with high-quality materials and a stylish design. The seats are comfortable and supportive, even on long journeys.
- Advanced Technology: The MBUX infotainment system is packed with features, and the driver-assistance systems enhance safety and convenience.

Cons:
- Ride Comfort: While the air suspension provides a comfortable ride in certain modes, the ride can be firm, especially in the sportier settings.
- Complexity: The car is packed with technology, which can make it more complex to maintain and repair.
- Fuel Economy: Fuel economy is not a strong point, especially with the V8 models.
- Rear Visibility: The sloping roofline can somewhat compromise rear visibility.
- Price: The AMG GT 4-Door Coupe is an expensive car, both to purchase and to maintain.
Buying Advice
When considering purchasing an AMG GT 4-Door Coupe, here's some advice to keep in mind:
- Consider Your Needs: Think about how you will use the car. If you prioritize fuel economy and a slightly more compliant ride, the 53 model might be a good choice. If you want the ultimate performance, the 63 or 63 S are the way to go.
- Pre-Purchase Inspection: Absolutely essential! Have a qualified Mercedes-Benz or AMG mechanic thoroughly inspect the car before you buy it. This will help you identify any potential issues and avoid costly surprises down the road. Pay particular attention to the engine, turbos, transmission, suspension, and electronics.
- Maintenance Records: Review the car's maintenance records carefully. Look for evidence of regular servicing, including oil changes, fluid flushes, and brake inspections. A well-maintained car is more likely to be reliable.
- Model Year Differences: Research the specific features and updates for each model year. Later model years may have improved technology and refined features.
- Check for Recalls: Check with Mercedes-Benz or the National Highway Traffic Safety Administration (NHTSA) for any outstanding recalls on the specific car you are considering.
- Negotiate the Price: The AMG GT 4-Door Coupe can depreciate relatively quickly. Be prepared to negotiate the price, especially on older models. Compare prices of similar cars in your area to get a sense of the market value.
- Warranty: If possible, purchase a car with a remaining factory warranty or consider purchasing an extended warranty. This can provide peace of mind and protect you from unexpected repair costs.
- Avoid Modified Vehicles: Unless you are very knowledgeable about performance modifications, it's generally best to avoid cars that have been heavily modified. Modifications can void the warranty and potentially compromise the car's reliability.
- Consider Certified Pre-Owned (CPO): A Certified Pre-Owned Mercedes-Benz will have undergone a thorough inspection and come with an extended warranty. This can be a good option for added peace of mind.
Years to Look For: Generally, later model years (2021 and newer) will have the most up-to-date technology and features. However, these will also be more expensive. 2019 and 2020 models can offer good value if you can find one in excellent condition with a solid maintenance history.
Years to Avoid: There aren't specific years to definitively *avoid*, but be extra cautious with early production 2019 models. These may be more likely to have been affected by early production issues such as turbocharger problems. Diligence and a thorough pre-purchase inspection are crucial regardless of the model year.
By carefully considering these factors, you can make an informed decision and find the perfect AMG GT 4-Door Coupe to meet your needs and budget.
