The Mercedes-AMG GT wasn’t only the successor to the Mercedes SLS AMG; it was also the first model to sport a Mercedes-AMG badge and the first model that got your blood pumping with that 4.0-liter V-8. It was a bit smaller than the SLS, so it targeted a completely different market of buyers, but it was still quite Amazing. And, despite the rumors that Mercedes wasn’t going to make a roadster variant of the GT, we’ve finally been graced with not one but two. The one you see here is the range-topping model and goes by the name GT C. The best part is that it’s a lot more than a GT coupe with its top chopped off. See, this baby takes on its own look and even gets some extra horsepower to go with it.

Now, don’t get it twisted, the rumors that Mercedes wasn’t going to make a roadster were pretty much dismissed when earlier this year when we got spy shots of a drop-top testing in the wild. So, we knew that one would eventually make its long-awaited debut. But, we didn’t know that we were going to get two different models. With the Paris Auto Show right around the corner, Mercedes found it fitting to drop some official details about its range-topping GT C Roadster, and we’re so happy they did. With that said, let’s dive on in a take a good look at the amazing Mercedes-AMG GT C Roadster.

Compared to the coupe, the GT C takes on its special look in a couple of different ways. The side profile below the beltline is nearly identical to that of the coupe. However, above the belt line, especially in the rear, there is some new design work. First off, the convertible top doesn’t take on the fastback look of the coup. Because of this, the rear deck lid is now considerably longer. It still as a slight grade to it that helps to enhance the cars overall sporty look. Between the taillights, it becomes obvious that the decklid doesn’t extend as far down the rear, and there is now a vent of sorts between the decklid and the rear fascia. The rear fascia also takes on a different look with an air vent in each corner. Instead of having a black, diffuser like insert outlined by the rear fascia, the rear fascia itself in actually taller now, with the area around the integrated exhaust outlets finished in the same color as the car.

The convertible top doesn’t take on the fastback look of the coup. Because of this, the rear deck lid is now considerably longer. It still as a slight grade to it that helps to enhance the cars overall sporty look.

More changes come to life up front where the roadster has a very dominating front grille with vertical slats and a big fat Mercedes emblem right in the middle. Down below, there is a horizontal slat in each corner intake and the traditional AMG styling to the lower spoiler area of the fascia. But, let’s talk about that soft top for a moment. It can be opened or closed at speeds of up to 31 mph and takes about 11 seconds to complete the transition. It can be hand in either black, red, or beige and is supported by a structure that is composed of magnesium, steel, and aluminum. There’s also an integrated aluminum cross-member and rollover bars for added protection should things get a little to skunk and the car lands belly up.

Outside of the things I’ve mentioned here, the GT C roadster is every bit an AMG GT as the rest of the clan. It features a sporty and muscular hood and those sharp but wild character lines on each side. The rear fenders appear to be flared out a bit like that of the Mercedes-AMG GT R, giving the car a more commanding stance. In short, it’s sexy all the way around and worth of a spot in any man’s garage.

The GT C Roadster gets the same amazing interior as the GT Coupe that brings the feeling of width while keeping an aviation-inspired theme.

Inside, the GT C Roadster gets the same amazing interior as the GT Coupe that brings the feeling of width while keeping an aviation-inspired theme. Perched on top of the dash you’ll find that tablet-like infotainment screen that is flanked on the left by a two-gauge instrument cluster with a TFT screen in the middle. As is the usual treatment with AMG-branded vehicles, the driver is in control with a flat-bottom steering wheel that also has a small mark at 12 o’clock. Three spoke in design; there are thumb buttons on each side spoke while the bottom spoke is wide open in the middle. Sitting below the infotainment screen are four circular vents that are about two-thirds of the size of the vent on each corner of the dash.

The two-tone nature of the dash matches that of the door trims. In this specific example, the top of the dash and door panels are black while the bottom of the dash and trim are a cream color. The center console sits nice and high, effectively giving the driver and passenger their own space. The silver insert atop the console adds a lot of character here with the AMG Drive Unit controls arranged as if they are cylinders in a V-8 engine. All told, the cabin is sleek, sexy, and inviting. It’s very well put together and has exception fit and fishing all the way around.

Drivetrain

And here’s where every man that has a need for speed starts to get excited. Under that long hood, you’ll find a hand-built 4.0-liter, Biturbo, V-8 engine. However, unlike the engine found in other GT models, this baby pumps out 550 horsepower and 502 pound-feet of torque. To help paint a clear picture, that’s 94 horsepower more than the GT Roadster, 47 horsepower more than what’s offered in the AMG GT S and just 27 horsepower less than what you get in the AMG GT R. With immediate response and a wide powerband that delivers maximum torque between 1,900 and 5,750 rpm, the GT C roadster can break the 60 mph barrier in 3.7 seconds on the way to a butthole-puckering top speed of 196 mph.

Under that long hood, you’ll find a hand-built 4.0-liter, Biturbo, V-8 engine. the GT C roadster can break the 60 mph barrier in 3.7 seconds on the way to a butthole-puckering top speed of 196 mph.

But, that’s not all that’s interesting here. The dual-clutch transmission that sends power to the rear wheels is positioned in a transverse layout at the rear axle and has been updated with new hardware and software to compensate for all that extra power — just like the rear end found in the GT R. Offering up seven speeds, the first gear now has a higher ratio while the last gear and final drive have a lower ratio. This makes the car much more responsive on the fly and surely a pleasure when you really get on it.

The GT C Roadster also gets the traditional AMG Drive Select, that includes models like “comfort” and “sport,” but the GT C comes available with a new mode known as “race.” This mode alters the tuning of the transmission even further to meet the quick shifting needs required for a fun day at the track. It brings exceptionally fast shift speeds while opening up the exhaust to provide even more emotion from the rear. Manual mode can be selected that will allow you to shift the transmission yourself because, I mean honestly, who really wants to let a car shift itself at the track? Not me. On top of this, the GT C also gets the AMG Sport Suspension along with AMG Ride Control, making this thing an absolute dream to drive during more extreme maneuvers. Furthermore, there’s also rear-wheel steering borrowed from the GT R to help improve not only agility but stability too.

But wait, there’s more. The standard GT Roadster has a mechanical locking differential, but not the GT C. The GT C gets an updated electronically controlled locking differential that is integrated into the transmission. It helps to improve the grip of the rear wheels which ultimately increases the limitation of speed when cornering.

Pricing

With the GT C expected to hit showrooms in the fall of 2017, Mercedes hasn’t said anything about pricing, but we do have at least some frame of reference. The GT Coupe is priced at $112,125, and we’re expecting the GT Roadster to command about 121,000 before options. That said, the GT C should command somewhere in the range of $130,000 to $135,000.

With the AMG GT aimed at the Porsche 911 Turbo and the GT Roadster aimed at the 911 Turbo Cabriolet, it’s only fitting that we pit the GT C against the 911 Turbo S Cabriolet. Powered by a 3.8-liter flat-six, the Turbo S delivers 580 horsepower – 30 ponies more than the GT C. With a 60-mph sprint of about 2.8 seconds with the Sport Chrono package and a top speed of 205 mph; the Porsche does have the upper hand in the performance department. But, that’s okay, because the Turbo S Cabriolet is priced at a divorce-induction $200,400. That’s about $60,000 more than the expected price of the GT C. Be that as it may, the 911 is just as elegant inside, and has it owns unique look outside. So, it really boils down to two things when choosing between the Porsche and the GT C – brand loyalty and whether or not it’s worth paying $60,000 extra to hit 60 mph a second faster.

Conclusion

Normally I knock on Mercedes-AMG a little bit because most of the time there’s a lot of the same car with little updates for power or performance – especially when there are multiple versions of the same car. But, in this case, I think Mercedes-AMG really outdid itself. The interior is practically identical to that of the 2016 GT Coupe, but the exterior of the GT C has taken some pretty decent enhancements to make it its own model. That front grille is brilliant and gives the car more of an exotic look while that lightweight and longer decklid adds a lot of character to the rear end. Plus, there’s that soft top that probably would have looked ugly if it maintained the fastback look. What do you think of the new GT C Roadster? Would you buy it if you had an extra $150,000 sitting around? Let us know in the comments below.

Mercedes-AMG is blowing even more fresh air into the AMG GT family. Shortly after the world premiere of the AMG GT R, AMG is presenting two exciting roadster variants of the two-seater sports car. Alongside the AMG GT Roadster, the AMG GT C Roadster enhances the portfolio with a completely new model variant. With an output of 550 hp and peak torque of 502 lb-ft, the AMG GT C is the most powerful new Roadster variant and uses some of the technical refinements of the AMG GT R. These include active rear axle steering and the electronically controlled rear axle locking differential. In combination with AMG RIDE CONTROL sport suspension, the AMG GT C Roadster guarantees dynamic performance at the very highest level. The AMG GT C Roadster also takes its lead from the top AMG GT R sports car where muscular proportions are concerned: the wider rear fenders create space for a wider track and wider wheels at the rear axle, allowing for excellent traction and even higher cornering speeds. The variable performance exhaust system also ensures an authentic V8 sound from the AMG Roadster.

The new Roadsters make hallmark AMG driving performance an even more intensive experience. "With our two Roadster models, we are strategically expanding the AMG GT family by two exciting variants. With the AMG GT C Roadster, we are also introducing a new model variant to which we have transferred main performance-related components from our top sports car, the AMG GT R. The result: a highly dynamic driving experience in a very exclusive ambience, coupled with that pure roadster feeling," says Tobias Moers, Chairman of Mercedes-AMG GmbH.

With the two Roadster variants the Mercedes-AMG GT family has now increased to five members. The two new sports cars with fabric soft tops likewise have the technical genes for which AMG is famous. These include a lightweight and torsionally rigid aluminum bodyshell plus powerful and efficient V8 biturbo engines. The entry level into the Roadster world is the AMG GT with an output of 469 hp.

The AMG GT C Roadster adds a completely new output level. With 550 hp it is the more powerful of the two new open-top sports cars.

The AMG GT C Roadster not only delivers more output and torque, it also impresses with numerous technical highlights from the Mercedes-AMG GT R for even more dynamic performance. Like the AMG GT R, the AMG GT C Roadster is recognizable by its wide, muscular rear end and large wheels. Other technical measures include the wider rear track and active rear axle steering.

The AMG GT C Roadster is also equipped with a lithium-ion battery and has more exclusive appointments. Standard features include a Nappa leather interior, AMG Performance steering wheel in Nappa leather/DINAMICA microfiber and the additional transmission mode "RACE."

Fully automatic: the weight-optimized fabric soft top

Both Roadsters are quickly transformed from coupes to open-top sports cars. The fabric roof opens and closes in around eleven seconds, and can do this at speeds of up to 31 mph. The three soft top colors (black, red and beige) can be chosen to suit the eleven exterior and ten interior colors. The three-layered fabric soft top is supported by a lightweight magnesium/steel/aluminum structure which helps to keep the center of gravity low. Additional rollover protection is provided by an integrated aluminum cross-member with rollover bars.

New output level: the handcrafted AMG 4.0L V8 biturbo engine

With the AMG GT C Roadster, Mercedes-AMG is introducing a further output level of the handcrafted 4.0L V8 biturbo engine, thereby underlining the exclusive character of the new model. At 550 hp, the peak output is 47 hp above that of the AMG GT S and 27 hp below the Mercedes-AMG GT R. The maximum torque of 502 lb-ft is available from 1,900 to 5,750 rpm. A sprint from zero to 60 mph is achieved in 3.7 seconds, accelerating on to a top speed of 196 mph.

The AMG GT Roadster has an output of 469 hp and 465 lb-ft of torque. This variant accelerates to 60 mph in 3.9 seconds and to a top speed of 188 mph.

The eight-cylinder engine thrills with its immediate response, a linear, finely controllable power delivery and powerful acceleration in all rpm ranges. The handcrafted AMG 4.0L V8 biturbo engine comes with well-proven twin turbocharging, with the two turbochargers not located outside on the cylinder banks, but rather between them in the V of the cylinders. The advantages of the "hot inner V" configuration include a compact engine design, spontaneous response from the turbochargers and low exhaust emissions thanks to optimum air flow for the close-coupled catalytic converters.

Also adapted: the dual-clutch transmission

The developers have also adapted the seven-speed dual clutch transmission in a transaxle arrangement at the rear axle to the new power level of the Mercedes-AMG GT C Roadster by modifying the hardware and software. The first gear of the AMG SPEEDSHIFT® DCT 7-speed sport transmission has a higher ratio, while seventh gear and the final drive have a lower ratio. This makes for even more agile acceleration and very fast responses to sudden accelerator movements.

The driver is able to set the AMG GT Roadster to his/her individual requirements using the AMG DYNAMIC SELECT controller. The three transmission modes "C" (Comfort), "S" (Sport), "S+" (Sport Plus) and the individually programmable setup "I" (Individual) allow a broad range of driving experiences from comfortable to very sporty.

The transmission mode "RACE" is additionally available for the Mercedes-AMG GT C Roadster. This mode optimally adjusts the shift strategy of the dual clutch transmission to the needs of the racetrack – very fast shift speeds and highly emotional engine sound are included. By pressing the separate "M" button in the center console, the driver can activate the manual transmission mode.

Pure sound: the AMG Performance Exhaust System

The AMG GT C Roadster is equipped with the AMG Performance Exhaust System as standard to obtain an even more emotional sound experience. Two variably adjustable flaps modulate the exhaust note of the Mercedes-AMG GT C Roadster authentically and directly. The flaps open and close depending on the selected AMG DRIVE SELECT mode, although they can also be controlled individually using a separate button in the AMG DRIVE UNIT. In the "Comfort" and "Sport" settings, the low-frequency sound typical of a V8 is designed for comfort. In "Sport+" and "RACE" modes the sound composition is far more emotional. The variable AMG Performance Exhaust System is also available as an option for the Mercedes-AMG GT Roadster.

Also for the Roadster models: active air management system from the AMG GT R

The two AMG Roadster variants have adopted a special technical highlight from the AMG GT R: the active air management system. Vertical louvers located in the lower area directly behind the front fascia can be opened and closed by an electric motor in around one second. This ensures that the cooling performance is according to need. Always achieving the optimum position requires highly intelligent and fast control.

During normal driving with no increased cooling requirement, the louvers are closed to reduce aerodynamic drag and specifically conduct the air to the underbody. Only when certain components reach predefined temperatures and the air requirement is particularly high do the louvers open to allow the maximum cooling airflow to the heat exchangers.

Highly expressive: athletic exterior design

From the expressive AMG Panamericana grille to the long, muscular hood and the wide rear end, the two-seater guarantees a pure sports car experience even when stationary. The striking AMG Panamericana grille underlines the motor racing heritage: 15 chrome-plated, vertical bars echo the look of the current Mercedes-AMG GT3 customer sports racing car. The new front bumper emphasizes the car’s width and gives it an athletic appearance on the road. Large outer air inlets ensure the supply of cooling air to the engine and the pronounced shoulder line is suggestive of a tensed muscle, enhancing the impression of sheer power and athleticism in combination with the new 19-inch and 20-inch AMG light-alloy wheels in a 5-twin-spoke design.

Muscular with an emphasis on width: the rear end

The rear end also features numerous, conspicuous innovations. The new aluminum fenders of the AMG GT C Roadster widen the open-top two-seater by 2.25-inches compared to the AMG GT Roadster, making it the same width as the AMG GT R. Compared to the AMG GT Roadster the muscular form also creates space for larger wheels and a wider track. Both measures make for traction while allowing higher cornering speeds. The likewise wider contours at the AMG GT C Roadster’s rear bumper improve airflow at the rear with large outer air vents. Both Roadster variants feature a rear spoiler integrated into the trunk lid which can be electrically extended and retracted at defined speeds, depending on the selected transmission mode.

Greater rigidity and low weight: Intelligent material mix

Mercedes-AMG also uses an intelligent material mix for the body structure of the AMG GT and GT C Roadster. Various aluminum alloys are used for the chassis and body and magnesium is used for the front deck. This extremely light element at the front reduces the inertia ahead of the front axle, thus improving agility.

The already rigid bodyshell structure has been specifically reinforced further to take account of the car’s design as a roadster: side skirts with greater wall thicknesses and more chambers make the structure more rigid. The dashboard support is braced against the windscreen surround by additional struts and a strut tower brace between the soft top and the tank reinforces the rear axle. A cross-member behind the seats supports the fixed roll-over protection system.

The trunk lid is particularly light, thanks to an innovative composite material. The load-bearing structure is of SMC (Sheet Molding Compound) with carbon fiber. These high-tech plastics excel with their light weight, great strength and first-class surface condition. These innovative materials were developed by the Mercedes-Benz TEC factory in Sindelfingen and brought to production maturity together with the AMG specialists in Affalterbach. This material combination is used for the first time in the new AMG Roadsters.

The AMG lightweight construction experts have also used a composite material for the wheel-catching struts. 50 percent lighter than the equivalent in steel, these composite components help to guide the front wheels onto the side members as part of the intended crash kinematics in an accident, and to hold them there.

Derived from motorsport: the AMG Sport Suspension

The AMG Sport Suspension likewise confirms the motor racing heritage of the new AMG Roadsters. Wishbones, steering knuckles and hub carriers on the front and rear axle are manufactured entirely out of forged aluminum to reduce the unsprung mass. The wheels are also guided by double wishbones. The resulting precision in camber and track allows high cornering speeds and gives the driver optimum, highly precise road feedback right up to the very high cornering limits.

In the Mercedes-AMG GT C Roadster, the sport suspension is combined with AMG RIDE CONTROL continuously variable, adaptive damping system. The system is electronically controlled and automatically adapts the damping on each wheel to the current handling situation, speed and road conditions.

Even more agility: active rear axle steering from the AMG GT R

As standard, the new Mercedes-AMG GT C Roadster responds even more sensitively thanks to the active rear axle steering that had its debut in the Mercedes-AMG GT R. The system offers an ideal combination of agility and stability - handling characteristics that are normally in direct conflict.

2018 Mercedes-AMG GT C Roadster High Resolution Exterior
- image 688403

Up to a speed of 62 mph, the rear wheels are turned in the opposite direction to the front wheels, resulting in significantly higher agility and increased driving pleasure with less steering input. In day-to-day driving the driver also benefits from a reduced turning circle.

Once the speed of the AMG GT C Roadster exceeds 62 mph, the system turns the rear wheels in the same direction as the front wheels, this noticeably improves handling stability. At the same time, the lateral force on the rear wheels builds up considerably faster when changing direction, which makes the response to steering inputs quicker. The driver also notices the high grip and stability of the Mercedes-AMG GT C Roadster during rapid changes of direction, without the usual tendency for the rear to break out.

On board as standard: the rear-axle locking differential

As standard the AMG GT C Roadster is equipped with an electronically controlled locking differential at the rear axle (The Mercedes-AMG GT Roadster comes with a mechanical locking differential), which is integrated into the compact transmission housing. Its sensitive and rapid control elevates the physical handling limits to a new level. It not only further improves the grip of the driven wheels, but also increases cornering speeds at the limit.

High quality and exclusivity: the interior

The interior design echoes the design lines of the exterior. The dashboard places an extreme emphasis on width, creating an impression of a powerful wing. High beltlines, concave door panels, dynamically rising center console and low seat position perfectly integrate the driver into the cockpit. The new, light-colored interior in Macchiato Beige Exclusive Nappa leather is available for the first time, lending the open-top sports car even more individuality and exclusivity.

More lateral support and comfort: AMG Performance seats

The optionally available AMG Performance seats provide even more lateral support with more heavily contoured backrest and seat cushion side bolsters. For the first time the AMG performance seat is also optionally available with the AIRSCARF® neck-level heating system, which makes open-air driving enjoyable even when the outside temperature is low. The air vent is seamlessly integrated into the seat’s head restraint area. To meet the individual preferences of customers, the temperature of the warm airflow can be set in three stages.

Customers wishing to enjoy comfortable temperatures even on very hot summer days will also opt for seat climate control, which is also available exclusively for the AMG Performance seat for the first time. The intensity of the cooling can also be set in three stages.

Impressive sound in the interior: Externed Coupled Subwoofer

The Burmester® Sound System and Burmester® High-End Sound System ensure a very special musical experience in the AMG GT Roadster. Both systems benefit from an innovation developed jointly by AMG and Burmester®: the Externed Coupled Subwoofer (ECS). This new bass sound reproduction system with an extremely low bass range turns the open two-seater into a mobile concert stage.

Instead of a subwoofer box of limited dimensions, ECS uses the entire interior as a bass box. This is made possible by a special aperture in the right rear wheel arch. The subwoofer is connected to the bodyshell via this aperture, transmitting the impressive sound.
