It could to be as early as 2019 if Mercedes-AMG pulls the trigger

Unveiled just a couple of years ago, the Mercedes-AMG GT has proven to be a worthy successor to the SLS AMG, despite being a bit smaller and rivaling the awesomeness that is the Porsche 911. Since it’s debut at the 2014 Paris Motor Show, the AMG GT has spawned three other versions, including the GT S Roadster, track-ready GT R, and the GT C Convertible. Power output for these models ranges anywhere between 456 horsepower and 443 pound-feet of torque in the entry-level GT all the way up to 577 horsepower and 516 pound-feet in the GT-R, all of which comes in one sexy and stylish package.

Just recently, AMG boss Tobias Moers told Autoblog that the next model in the GT lineup will be a coupe version of the GT C, but it was also disclosed that a roadster version of the GT R was being discussed. While that does sound promising, it’s nowhere near what we would call a confirmation. It does, however, tell us that it is possible and, as such, we’ve decided to create a rendering to see just what a GT R Roadster would look like. As is the usual case with coupes turned roadster, there’s not much in the way of difference below the waistline, but the GT R Roadster would obviously have its own uniqueness.

So far, little is known about what kind of time frame we’re looking at for even the GT C Coupe, but a leaked roadmap document last year showed that it might come to be by late 2017, which would put the GT R Roadster in line to show up sometime toward the end of 2019. We’ve still got some time before we’ll see the GT R Roadster (if we ever will), but let’s take a look at the rendering we’ve put together and talk a little more about it.

Continue reading to learn more about the Mercedes-AMG GT R Roadster.


We expect the GT R Roadster to be identical to the coupe version from the waste down. That means it will have the same dominating AMG grille with chromed out vertical slats and a big Mercedes emblem. Down below, the fascia will feature a built-in lower spoiler with a smaller spoiler located right in the middle. The corner air inlets will be massive with two horizontal slats that are recessed and help to give the car a more menacing look. The headlight units should be identical to that of the coupe version.

We suspect that the rear deck area will have a similar angle toward the rear, but further forward where the body opens up, it should be nearly flat with a few distinct body lines to add character.

Moving over to the side profile, the same fender vents and body lines will be in place. Like the coupe version, the corner vents will feature gloss black inserts and the “V8 Biturbo” lettering. The big news here will happen above the waistline where we’ve removed the roof and made some minor modifications. The windshield will likely be just a bit shorter and will be full framed. The A-Pillars should keep the same angle for aerodynamic purposes, but further back, there will be no rear quarter glass, and there will be roll bars located behind the seats for safety purposes, obviously. A gloss black strip will likely run from the top of the doors and circle around to the rear where there will be an all-new look, at least up top, anyway.

We suspect that the rear deck area will have a similar angle toward the rear, but further forward where the body opens up, it should be nearly flat with a few distinct body lines to add character. The same spoiler and spoiler mount should carry over to the roadster, as will everything else from the taillights down. All told, it will be one sexy looking and powerful roadster, and a design like this definitely works in roadster form as well.

Considering the GT competes directly with the Porsche 911, we have to get a little creative about looking to a competitor for the GT R Roadster. The GT R competes directly against the track-ready Porsche 911 GT3, but that’s not available in roadster or convertible form. The closest match would be the Porsche 911 Turbo S, which is available in coupe or convertible form, and has enough power to compete too!

Much like we expect for the GT R Roadster, the 911 Turbo S Convertible is identical to its roofed sibling below the waistline. The downside to the 911 convertible, though, is that it’s nowhere near as aggressive as the GT R. Outside of the standard Porsche design, like the uneventful hood and big bubbly headlights, the 911 Turbo S Convertible does have a pair of massive corner intakes that are split by a thin but wide air dam down below. The fascia itself is shaped to create a spoiler-like element on the bottom, which undoubtedly provides a little bit of downforce.

Moving to the side, you see the same design cues below the waistline. The side skirts travel from the front wheel arch and get a bit wider toward the rear where they bubble out to match the wide flaring around the rear wheels. Just head of the rear wheels is the air intake ports for the rear-mounted engine. The uppermost body line follows the contour of the lower body and gently fades away into the taillights. Up top, however, it literally looks like Porsche cut the rear glass, and roof right off. There’s no real difference here aside from the area behind the seats that now houses the retractable roof. The upswept look of the waistline does give the car a sporty appearance, and let’s be honest here – it’s a 911, it’s hard to beat.

Compared to the GTR, the 911 Turbo S is somewhat toned down. The rear hood features a pair of sexy vents with vertically oriented slats and a small active spoiler to help keep the rear wheels locked to the ground. Down below, the rear fascia is sculpted and, while it doesn’t feature an aggressive diffuser like the GT R, it does have just the right amount of aggressiveness. The lower portion of the rear fascia is recessed just a bit with twin, dual exhaust outlets and a simulated air outlet on each corner. The air outlets lead into the rear reflectors and also have two horizontal slats for a little extra style.

If we know Mercedes-AMG, and we do, the interior of the GT R Roadster will be identical to that of the coupe with the exception of unlimited headroom and the addition of roll bars behind the rear seats. This means that there will be two, manually adjustable bucket racing seats with AMG lettering and contrasting seatbelts. A flat bottom steering wheel and digital instrument cluster is a guarantee. The seats, steering wheel, and much of the trim will get the Nappa leather and Dinamica microfiber treatment to go with contrast stitching. A large infotainment display will hover out of the center stack and will feature custom AMG graphics.

Note: Mercedes-AMG GT R interior shown here.

The interior of the GT R Roadster will be identical to that of the coupe with the exception of unlimited headroom and the addition of roll bars behind the rear seats.

Expect the roadster to get the standard Interior Night package that comes in its coupe brother. This package includes shift paddles, a steering wheel bezel, and door sills in high-gloss black to go with the standard Piano Lacquer trim color package that brings a little bit of extra shine to certain things like the center console trim and HVAC controls. Mercedes will likely take the opportunity to add some extra contrast by making the roll bars behind the rear seats a lighter color compared to the interior – as you can see from our rendering we think they will be silver in nature. Needless to say, it should be one comfortable and supportive cabin to be in whether it be a Sunday drive or a wild day at the track (assuming blazing around the track at high speed with no roof is your thing, that is.)

The Competition

The Porsche 911 Turbo S doesn’t exactly have a low-quality interior, but it really doesn’t have what it takes to be a true competitor to the GT R Roadster. The interior from the 911 GT3 would be a bit closer, but that model isn’t available with a drop top and isn’t anywhere near as powerful. The Turbo S is still worth writing home about, though, as the interior is quite pleasing and comfortable. There’s plenty of leather found on the dash, door trim, center console, and seats, while the overall design of the dash is pleasing to look at. The instrument cluster features three primary gauges, and the steering wheel has a number of thumb controls. Sitting on top of the dash is an analog clock to add a bit of luxury where there was once boredom.

Looking at the center stack, you’ll find Porsche’s new Communication Management system with Online Navigation. It’s a system Porsche recently developed and features a real glass screen, and is mounted flush with the console, giving it a perfect look. It comes with the standard Connect Plus Module, real-time traffic data, and some options can be controlled by your smartphone with connectivity via Wi-Fi, Bluetooth, or USB cable. A Bose sound system comes standard while a Burmester system is available if you’re willing to pony up the dough. All told, the 911 does have a sexy cabin, but if you really want those plush materials, your only real choice is the future GT R Roadster. Of course, you can buy the Porsche 911 now, so if you don’t want to wait, don’t worry; we won’t judge you!


When it comes to the motivation behind the Mercedes-AMG GT R Roadster, you’ll find the same 4.0-liter, Biturbo, V-8 found in the rest of the lineup, but like it’s roofed brethren, it will produce a staggering 577 horsepower and 516 pound-feet of torque. That’s an extra 74 ponies and 35 pound-feet over the same engine available in the GT S. The trick to getting the extra power came by way of new turbochargers, increased boost pressure, and a complete ECU remapping. Shifting duties are handled by a seven-speed dual clutch. Now, as far as performance goes, the GT R Roadster will be just a tad slower than its roofed brethren because of the missing roof. This should slow the 60-mph sprint down to about 3.6 seconds (compared to 3.5 in the coupe) Top speed will likely remain around the same at 198 mph, but could drop by a couple dashes.

The suspension and chassis will make use of adjustable coil overs, an adjustable traction control system, and a limited-slip differential. The latter is electronically controlled while the traction system is derived from the GT3 track car. The Roadster should also get active rear-wheel steering like the coupe, which makes cornering a breeze, even at higher speeds. All told, this should be one mean roadster on the track or the street.

The Competition

When it comes to the Porsche 911 Turbo S, this is the department where it will really compete against the AMG GT R Roadster. See the Turbo S comes with the 3.8-liter Boxer-6 mounted in the rear. It delivers a staggering and GT R-beating 580 horsepower and 552 pound-feet of torque. With the standard compression ratio of 9.8:1 the engine is able to push the 911 Turbo S Convertible to 60 mph in 2.9 seconds with the Sport Chrono package on the way to a top speed of 205 mph. Power is routed from the engine via a PDK transmission to all four wheels, meaning that this baby is also a mean on in the corners.

Needless to say, that if you’re really about that sprint to 60 mph and top speed, the 911 Turbo S is the way to go, but it will cost you. But, we’ll talk more about that in the prices section below.

Top Speed 198 mph 198 mph

At this point, there’s no telling what kind of price tag Mercedes-AMG will throw on the GT R Roadster, but we know that the coupe should retail for €165,410 when it goes on sale in the Spring of 2017. That converts to about $178,000 before taxes, options, and destination charges. So, with that in mind, it’s safe to say a Roadster version would likely fetch at least $195,000 at current exchange rates. It could go for more, however, but AMG would be doing right to keep it below the $200k threshold as the Porsche 911 Turbo S Convertible goes for $200,400. Considering the GT R Roadster will be more aggressive on the outside, more luxurious on the inside, but slightly less powerful, $195,000 seems pretty reasonable, don’t you think?

While little is actually known about the future 570S spider, it is known that McLaren should be introducing the drop-top sometime in 2017. As such, it should receive the same exterior look, minus a few nips and tucks above the waistline to accommodate its new topless nature. The interior should be on par with that of the GT R Roadster, and will a leather-trimmed dash and seats, as well as the option for things like Nappa leather, Alcantara, and carbon fiber trim. Motivation will come from a 3.8-liter V-8 that delivers 562 horsepower and 443 pound-feet of torque. With the Coupe version hitting 62 mph in 3.2 seconds and 124 mph in just 9.5 seconds, the Spider should make the same benchmarks in 3.3 seconds and 9.7 seconds, respectively. Top speed should be around 202 mph. The 570S Spider is also expected to fetch around $200,000, so it should be considered a stiff competitor for the GT R Roadster.

Sure, we have a while to wait before we see the GT R Roadster, and that’s if Mercedes-AMG even does it. In that conversation with the guys over at Autoblog, Moer’s quote wasn’t exactly as promising as we would have liked, saying “it’s just a discussion going on, we talked about it in the company, but I don’t know the market potential about that.” Even with that being said, it’s still enough to get us excited, because why not? The AMG GT family is growing, and while Moer’s might not be sure about the market potential, I can guarantee there are more than a few guys out there with the money and desire to own a 577-horsepower GT R Roadster. I don’t think the question really is if, but rather when we’ll see it. I wouldn’t expect to see it before 2019, but it could be 2020 before it finally becomes a real model. Until then, enjoy our rendering and let us know what you think in the comments section below.
