Four door Mercedes-AMG GT 63 is a rare case when a manufacturer managed to combine the aggressive design of a supercar with the practicality of a family sedan. The model, which debuted in 2018, was the answer Mercedes-Benz on Porsche Panamera Turbo and Audi RS7, but with a signature twist: under the hood is hidden 4.0 liter twin-turbo V8, accelerating the car to 100 km/h faster than many sports cars. In this article we will look at why GT 63 4-Door remains one of the most desirable cars in the premium segment, despite the high price and appetite for fuel.

The car is offered in two versions: standard GT 63 (585 hp) and β€œcharged” GT 63 S (630 hp), and the latter is capable of accelerating to 315 km/h - a record figure for serial sedans at the time of release. But such dynamics come at a price: fuel consumption in the combined cycle reaches 14–16 l/100 km, and the cost of service in official services is affordable. So is the game worth the candle? Let's figure out who this car is suitable for, what its weak points are and how to save money on your purchase.

Technical specifications: what the 4.0-liter monster hides

Heart Mercedes-AMG GT 63 4-Door - this is M178 biturbo engine, which was also installed on AMG GT R and SL 63. In the basic version, the motor develops 585 hp and 800 Nm torque, and in modification GT 63 S these numbers rise to 630 hp and 900 Nm accordingly. Acceleration to 100 km/h takes 3.4 seconds for GT 63 and 3.2 seconds for GT 63 S β€” faster than many supercars like Lamborghini HuracΓ‘n.

Gearbox - 9-speed automatic AMG Speedshift MCT, which is distinguished by lightning-fast shifts and the ability to manually control via steering wheel paddle shifters. Drive - full (4Matic+) with electronic differential locks, which allows efficient distribution of power between the axles. Adaptive suspension (AMG Ride Control), with the ability to select driving modes: from comfortable Comfort to extreme Race.

  • πŸ”₯ Maximum speed: 310 km/h (GT 63) / 315 km/h (GT 63 S)
  • ⚑ Acceleration 0–100 km/h: 3.4 s / 3.2 s
  • β›½ Fuel consumption (combined cycle): 14.3–16.1 l/100 km
  • πŸ”§ Tank volume: 80 liters (fill with 98 gasoline)

A feature of the M178 engine is the β€œhot-vee” system, when the turbines are located inside the camber of the cylinder block. This shortens the exhaust path, reduces turbo lag and improves low-rpm performance. However, this approach complicates access to turbines during repairs - replacing them costs 1.5–2 million rubles (with work).

πŸ”Ή Is it possible to drive an AMG GT 63 in winter?

Yes, but with reservations:

  • Be sure to install winter tires (for example, Michelin Pilot Alpin 5 or Pirelli Winter Sottozero).
  • Disable mode Race β€” it makes the car too harsh in the snow.
  • Check your work heated steering wheel and seats (in cold weather they may fail).

Fuel consumption in winter increases to 18–20 l/100 km due to warming up and slipping.

πŸ”Ή What is the service life of the M178 engine?

With proper maintenance (oil change every 10–12 thousand km, fuel consumption not lower than AI-98) engine life is 250–300 thousand km. However:

  • Turbines require replacement every 80–100 thousand km (cost - 1.2–1.5 million rubles).
  • The timing chain is designed for 150–200 thousand km, but its condition needs to be checked every 60 thousand km.

Important: avoid short trips (less than 10 km) - this leads to the formation of carbon deposits on the valves.

πŸ”Ή What alternatives to the AMG GT 63 should we consider?

If you need a fast 4 door car, but... AMG GT 63 seems too expensive to maintain, please note:

  • Porsche Panamera Turbo S - more reliable, with a hybrid version.
  • Audi RS7 - more practical (large trunk), cheaper to repair.
  • BMW M5 Competition β€” more dynamic on turns, but less comfortable.
  • Tesla Model S Plaid β€” if you are ready to switch to electricity (acceleration from 0–100 km/h in 2.1 s!).
πŸ”Ή Is it possible to install gas equipment on the AMG GT 63?

Technically possible, but highly not recommended. Reasons:
