Mercedes-AMG GT 4-door coupe: A favorite son and a racetrack monster

Power, punch, driving fun, and high levels of everyday utility and comfort — the Mercedes-AMG GT 4-door coupe that we’ve put on the road combines all of these attributes in a way that few other cars can match.

Our new four-door coupe is really stunning. After a development period of just over three years, this four-door sports car is now going into production and will soon be delivered to customers.

We’re making it a full dozen!

As the head of development, I’m proud of the fact that our Mercedes-AMG GT is available in many different variants. This model series, which we’ve developed, consists of seven models so far. These purebred sports cars have now been joined by five different family-friendly variants of our AMG GT 4-door coupe. I

n my opinion, the previous GT models have made a key contribution to our company’s brand image in recent years. Many of the aspects that people associate with AMG today have been defined by these models. The aim of our new development process was to transfer the sports car genes of the two-door GT to a four-door concept that remains authentic. We’ve also tried to ensure that the new model offers a high level of everyday utility and considerably more comfort.

“Both of them” instead of “either one or the other”

For me and my team, it was a huge challenge to envisage such a wide range of vehicle characteristics as was the case with our AMG GT 4-door coupe. Sportiness and comfort, top performance and efficiency, agility and the most high-powered dynamics, plus a flawlessly attractive visual package — our task was to harmoniously unite these supposedly contrasting qualities in one vehicle. I think we’ve definitely succeeded in doing that.

And that’s not only my own opinion or the view of the development team. A driving presentation for journalists has just ended in Austin, Texas, and our talks with the media representatives, as well as the resulting media reports, have confirmed that our work has been successful. It’s a major accolade for the entire team!

Whether I’m burning up the racetrack or going for a drive with my family, the four-door variant of the GT makes no compromises between sportiness and comfort — it can do both. It really does unite opposites. We were determined to make sure that our customers feel that harmony in every possible driving situation.

Feel claustrophobic in sports cars? Not in this one!

The aspects of our four-door GT that appeal most to me personally are the spaciousness as well as the design. We’ve implemented a dimensional concept that offers ample seating comfort in the rear compartment even for people like me. And that’s saying a lot, because at 1.94 meters I’m fairly tall. Customers have the option of configuring the rear passenger compartment of their vehicle in different ways. The Mercedes-AMG GT 4-door coupe has four seats as standard. In the rear it has two individual seats and a console located between them.

Customers can also choose a variably foldable rear bench seat that enables the car to seat five occupants. In the third variant, the high-class rear passenger compartment, the occupants in the rear have two adjustable individual seats and a business console that gives them access to various infotainment services. Thanks to massage functions and ambience lighting, the four-door GT becomes a full-fledged luxury liner. We’ve even provided the GT with a sports car scent. Another aspect I consider especially successful is the rotary adjuster with an integrated TFT display on the high-performance steering wheel. The driver can use it to spontaneously change the drive program.

In my opinion, it’s sometimes the simple things that make the customer’s life much easier. For example, we’ve attached a piece of fabric to the interior of the trunk. To prevent your clothes from being soiled when the trunk is being loaded or unloaded, this piece of fabric can be thrown over the rear center section. This might not sound too exciting at first, but in daily use customers will appreciate the way it keeps their clothes clean.

Top performance in the AMG GT 4-door coupe

But the best is yet to come: In addition to offering comfort of every kind, this car also provides maximum driving pleasure. Just take a look at the performance data of the most-powerful model of our four-door GT when it hits the road: 639 hp (Mercedes-AMG GT 63 S 4MATIC+ 4-Türer Coupé: Kraftstoffverbrauch kombiniert: 11,3 l/100 km; CO2-Emissionen kombiniert: 257 g/km //) and a maximum of 900 Nm of torque over a broad speed range from 2,500 to 4,500 rpm. In just 3.2 seconds, this racing car can sprint from 0 to 100 km/h. Its highest speed is 315 km/h.

A newly developed twin-scroll exhaust-gas turbocharger gives the four-liter V8 engine its breathtaking power. The turbocharger’s special feature is its ball bearing-mounted compressor and turbine shafts, which minimize internal friction. That’s how we achieve an extremely fast response and optimal cylinder charge. In addition, our highly efficient V8 engine has a cylinder shutoff feature.

Power alone doesn’t make drivers happy

In my opinion, we’ve created absolute superlatives in the segment of two-seater sports cars, from the first GT to the GT R. We wanted to give the four-door model a similar racecar personality. The vehicle stands out because of the extreme torsional rigidity of its bodyshell design. In addition to the cast components, we relied on a material mix of aluminum profiles and sheet steel. We also attached carbon parts at the right locations to provide additional rigidity. These are crucial prerequisites if a car in this category is to offer drivers such outstanding driving dynamics.

With our GT 4-door coupe, our customers don’t need to choose between sportiness and everyday utility. The reason for that is AMG DYNAMICS, a system that makes it possible to offer diverse forms of vehicle agility. Depending on the situation, it automatically chooses between the various driving functions. The responsiveness of the engine and the chassis, the control strategy of the all-wheel system, the newly developed ESP, the rear axle steering, and the electronically controlled locking differential — all of these parameters are optimally harmonized by the system. In addition, the model has dynamically controlled engine mounts that spontaneously adapt themselves to every condition of the road surface.

What I personally consider remarkable is the speed-dependent interplay between the momentary drive program and the aerodynamic components. Whether the setting is “Comfort,” “Sport,” “Sport+,” or “Race” — in each of these drive programs, which can be freely selected, the rear spoiler and the entire air control system change their setting angles as needed. The special twist is that this creates the proper balance between momentum and downforce, as well as the corresponding drag coefficient, in every driving situation. Not very many vehicles can do that.

Farewell to the ideal line!

Obviously, a car that has so many technical features supports the driver’s performance in many ways. All the same, a small anecdote from our numerous test drives in the GT 4-door coupe on the race track reminds me of some home truths. I was driving behind the car of the legendary DTM driver Bernd Schneider, who was burning up the asphalt. For a few rounds I had stuck close behind this professional race car driver, but I braked too late behind a bump on the track, and that meant I had a slight delay going in to the next curve. Bernd had noticed my tiny slip in his rearview mirror.

With a grin, he sent me the following radio message: “Feel free to continue driving behind me for a while. I think I know this neighborhood pretty well.” It all goes to show that there’s no substitute for concentration and driving skill, especially if you’re driving in sports car mode. However, an AMG has to be controllable in every possible situation, and it has to react in a predictable way! The driver must be able to rely on his car at all times.

From Sindelfingen to the world

Because we want customers to be able to experience the fascination of this four-door model for themselves very soon, we and our colleagues at the production plant in Sindelfingen are focusing on a single goal: building as many units of the Mercedes-AMG GT 4-door coupe as soon as possible. The ramp-up process for the production of a completely new model is always a very complex challenge.

This process would not have been possible without the flexibility that the plant in Sindelfingen offers us. The production of this vehicle has been integrated into the plant’s ongoing production process. I think that our excellent cooperation with our colleagues in Sindelfingen has been at least as important. We’ve overcome the obstacles together — and now it’s time to put our “baby” on the road.
