Appearance Mercedes-AMG GT 63 S became a landmark event for the entire industry, as the German concern for the first time combined the aggressive dynamics of a sports coupe with the practicality of a four-door sedan. This car was created not just as a fast car for the city, but as a complete tool for those who need maximum performance in any conditions. Owners get access to technologies previously available only on track cars, but in a comfortable cabin.
Many car enthusiasts are still arguing whether it is worth overpaying for the version GT 63 S compared to younger modifications. The difference lies not only in engine power, but also in chassis settings and all-wheel drive system 4MATIC+ and aerodynamic elements. If you are considering purchasing this car, it is important to understand that maintaining such equipment requires a serious approach and financial investment.
In this article we will analyze all the technical nuances that are hidden behind the loud name of the model. We will pay special attention to real fuel consumption, which often becomes an unpleasant surprise for new owners, and we will also touch upon issues of reliability of complex electronics and mechanics. The EQ Boost system adds 22 hp. and 250 Nm of torque, which is critical for eliminating turbo lag. Let's dive into the details.
Engine and technical specifications
With my heart Mercedes-AMG GT 63 S is the legendary M177/M178 4.0 liter engine. This is a V-shaped “eight” with two turbines located inside the camber of the cylinder block. This arrangement allows the exhaust gases to shorten the path to the turbines, providing instant response to the gas pedal. This was a major challenge for AMG engineers, as it required solving heat dissipation issues in a confined space.
In the standard version, the engine produces colossal 639 horsepower and 900 Nm of torque. However, if you activate the mode RACE START, the system briefly increases output, allowing a car weighing more than two tons to accelerate to 100 km/h in 3.2 seconds. This time is comparable to many purebred supercars, making the sedan one of the leaders in its class.
⚠️ Attention: Long-term driving at high speeds in RACE+ can lead to overheating of the oil in the gearbox and differentials, so keep an eye on the temperature sensors.
The key element of the transmission is a 9-speed gearbox MCT (Multi-Clutch Transmission). Unlike classic torque converter automatics, this is done using a wet clutch, which provides a more direct connection to the engine and eliminates energy loss. Shifts occur at lightning speed, especially in manual control mode via the steering wheel paddle shifters.
Dynamics and all-wheel drive systems
Controllability GT 63 S radically different from conventional Mercedes models thanks to the all-wheel drive system 4MATIC+. It is capable of redistributing torque not only between the axles, but also between the rear wheels. In standard mode, the car has a light rear-wheel drive nature, which allows an experienced driver to control drifts.
When selecting a mode Sport+ or RACE electronics instantly locks the cross-axle differentials, turning the car into a track projectile. The rear steering axle also contributes by reducing the turning radius at low speeds and increasing stability at high speeds. This makes it feel like you're driving a smaller car.
The braking system also deserves special mention. The optional carbon ceramic discs provide phenomenal braking performance even after multiple heat cycles. However, they are very expensive to replace, so for aggressive track driving, it is recommended to use separate sets of brake pads.
Fuel consumption and efficiency
When talking about such a powerful engine, don't count on the modest numbers on the receipt at the gas station. In an urban cycle with frequent traffic jams Mercedes-AMG GT 63 S consumes from 18 to 22 liters of gasoline per 100 km. If you like dynamic driving, the on-board computer needle easily rises to the mark 25-28 liters.
On the highway, when driving at a cruising speed of 110-120 km/h and 9th gear engaged, the consumption drops to a quite acceptable 10-11 liters. However, as soon as you step on the gas to overtake, the instantaneous fuel injection system increases the gas supply significantly. System Eco Start/Stop helps save fuel in traffic jams, but its operation can seem rough due to the powerful engine.
The fuel tank capacity is 80 liters, which allows you to cover about 400-500 km in a combined cycle without refueling. For a car of this class, this is an average figure that requires route planning for long trips. The use of gasoline with an octane number below AI-98 is strictly not recommended, as this can lead to detonation and a decrease in power.
Factors affecting consumption
The biggest influence on consumption is driven by driving style, use of climate control, tire pressure and road surface quality. Aggressive acceleration increases fuel consumption by 30-40%.
Interior, technology and comfort
Salon GT 63 S represents a synthesis of luxury and sporty aggression. Seats with integrated headrests and an extended range of adjustments provide excellent lateral support. Leather trim Nappa and decorative inserts in carbon or open-pored oak create a unique atmosphere.
Multimedia system MBUX equipped with two huge displays combined into a single panel. The voice assistant understands natural speech and allows you to control navigation, music and climate without taking your hands off the wheel. The driver also has access to a windshield projection that puts critical information directly into the driver's field of vision.

Maintenance and common faults
Car ownership level Mercedes-AMG requires strict adherence to maintenance regulations. The engine oil change interval is 10,000 km or once a year, but during active use it is better to reduce it to 7-8 thousand kilometers. Use of original oils with approval MB 229.5 or MB 229.6 necessarily.
One of the common problems with early versions was corrosion of the cooling system and intercooler pipes. Also, owners sometimes encounter errors in oxygen sensors and lambda probes. Complex electronics require diagnostics only with certified equipment Xentry, since universal scanners may not see AMG-specific error codes.
☑️ Scheduled maintenance for AMG GT 63 S
The service life of brake discs and pads directly depends on your driving style. During city driving, the front pads last about 20-25 thousand km, and the rear ones - up to 40 thousand. Carbon ceramics last much longer, but it is extremely sensitive to impacts and chips, so in winter you need to be extremely careful on roads with reagents and crushed stone.
Potential for tuning and modifications
The M177 engine has a huge reserve of durability, which makes it an excellent platform for tuning. Basic chip tuning (Stage 1) allows you to safely increase power to 700-720 hp. without replacing hardware. For more serious results (Stage 2 and above), the installation of downpipes and a cooling system is required.
External tuning often includes the installation of forged wheels to reduce unsprung weight and improve acceleration dynamics. Also popular are carbon body kits, which not only change the appearance, but also improve aerodynamics by pinching the rear axle at high speeds.
When tuning the exhaust system, be sure to reflash the catalysts in the ECU, otherwise the Check Engine error will light up and the car will go into emergency mode.
