The Mercedes-AMG GT 4-Door Coupe is Here, and it’s Basically a CLS With More Power

The wait is over and the AMG GT Sedan – oops, I mean 4-Door Coupe – is finally here. It hits the scene in three different trim levels with the GT 53 being the baby of the bunch followed by the GT 63 and GT 63S. It delivers anywhere between 429 horsepower and 630 horsepower, with the GT 53 using being the only one of the three to get an inline-six and is considered a mild hybrid. The exterior is exactly what you’ve seen before, as long as you’ve seen the CLS, but there are a few tweaks to differentiate the two on the outside while the inside gets the traditional GT-style cabin, dash and 12.3-inch display screens included

The AMG GT 4-Door Coupe is really just a CLS with a few tweaks here and there. Sorry to break it to you folks, but it’s true. The front fascia is nearly identical, with the exception of the headlights being taller in the outer corners, ultimately changing the shape of the front fascia, while the grill is nearly identical, with the exception of the vertical slats. Down below, the fascia is the exact same, minus the BMW M2-styled inserts around the air intakes as opposed to a pair of vertical louvers found on the CLS. The hood gets a pair of nostril lines in the center while the side profile is outright identical below the beltline.

Seriously, the GT 4-Door even has the same lower body line and side skirts found on the CLS. Above the beltline, things change a bit, but not much. Mercedes kept the same A-Pillars and window shaping up front, but out back the beltline takes a sharp curve upward to finish off in a point that’s aimed toward the rear spoiler. It’s a much better look than the stationary half-moon glass of the CLS, but it’s pretty clear that Mercedes reused the CLS template.

Around back the differences between the two are quite subtle with the GT 4-Door having a shorter rear glass and more refined C-Pillars. The taillights are thinner, and the deck lid shorter. The CLS is even a little sportier back here with the upswept decklid the AMG GT 4-Door doesn’t have. Looking from the rear, you can see exactly what Mercedes did to make the GT not a CLS – they changed the shape of the rear door glass and added a piece of glass to the C-Pillar.

To really add insult to injury, Mercedes even used the same rear fascia for the GT 4-Door with a slightly wider license plate recess and shallower vents in the corners. The rear diffuser is what the CLS should have had, with an opening in the middle, nestled nicely between the twin, dual exhaust outlets. It’s exciting that it’s here, but we have to deduct a few points for Mercedes lack of originality on this one.

Mercedes-AMG GT 4-Door Coupe Interior

Inside, the GT 4-Door Coupe did receive the AMG GT DNA, but so did the CLS, so there’s still really no selling point here as to why you would take the GT 4-Door over the CLS. You get the two 12.3-inch screens, the wavy dash, and the large center console. The center console, at least, takes on the GT styling with the large polished aluminum insert and with a column of buttons on either side.

The GT 4-Door does get some very supportive seats with huge bolsters on the sides and yellow contrast stitching, of course. There’s a flat-bottom steering wheel that’s showcased with carbon fiber at the top and bottom to go with the 12 O’clock stripe and split bottom spoke. Carbon fiber adorns the door trim panels up top as well as the central portion of the dash where the HVAC vents are located. The blue accenting LED stripe connects the doors to the dash and provides that relaxing ambiance.

At first glance, you might think that the GT 4-Door has a bench, but that’s really not the case at all. The outside seats mimic the front with bolstering on the cushions and seatbacks, while the space in between is reserved for a center console of sorts. The contrast stitching matches the seatbelts here too, but the smaller rear doors leave a little something to be desired as they seem crowded and just a little too busy.

Mercedes-AMG GT 4-Door Performance

The AMG GT 4-Door has as much as 630 horsepower at its disposal if you opt for the GT 63S. The power is delivered by a 4.0-liter, Biturbo, V-8 – the same engine that sits inside the GT 63, but is tuned to deliver 577 horsepower. Both engines feature cylinder deactivation for better fuel economy while the nine-speed AMG Speedshift MCT handles shifting duties. Both have a wet clutch and deliver power to all four wheels.

There’s also an AMG GT 53 that is powered by Mercedes’ 3.0-liter inline-six. It delivers a cool 429 horsepower but is also a mild hybrid with Mercedes’ EQ boost system. That system pumps in an extra 21 horsepower and 184 pound-feet of torque on demand, so there’s a little extra oomph thanks to the that. This engine, unlike the V-8, is mated to the nine-speed, AMG Speedshift TCT transmission. What’s the difference? The TCT uses a conventional torque converter as opposed to the wet clutch system found on the MCT.

The GT 53 also has all-wheel drive but opting for the V-8 gives you the option of “drift mode,” which sends all that power to the rear wheels so you can get yourself into a little trouble every now and then. Well, let me correct that statement. Drift mode is standard on the 63 S, but if you want it on the 63, you’ll have to pony up that dough.

All told, the GT 63 S will get you to 60 mph in 3.1 seconds – just enough to beat the Panamera Turbo S E-Hybrid to the benchmark. The standard 63 will make the run in 3.3 seconds with the 53 making it there In 4.4 seconds. Of course, these are estimates, but Mercedes does say that they can hit 195 mph, 193 mph, and 174 mph, respectively.

The Bottom Line

The Mercedes-AMG GT 4-Door won’t go on sale until next year, but one really has to question is if it’s worth waiting considering the Mercedes CLS will undoubtedly come in much cheaper and offers up 362 ponies in base form. By the time an AMG model comes into play, you’ll probably be able to get 450+ plus horsepower for quite the discount compared to what you’ll be asked to pay for the AMG GT 4-Door. Then again, one has to ask what’s in a name. Is the name itself really worth ponying up all that extra cheddar, even with the knowledge that the car itself is nothing more than a facelifted CLS with a few AMG cues?

We can’t tell you what to think, but Mercedes certainly didn’t put too much work into the design of this car. It’s quite disappointing after all the waiting and speculation. What do you think? Let us know in the comments section below.
