Overview

As the performance division of Mercedes-Benz, AMG creates works of art that are desirable both on the racetracks and on the streets around the world. The GT Roadster exemplifies its badge value. Each AMG vehicle is a product of extensive labor by craftsmen, designers, and engineers who built the car for the ultimate driving pleasure.

The base model of the 2018 Mercedes-Benz AMG GT Roadster is a brilliant car, with 469 horsepower and 465 lb-ft of torque from a 4-liter V-8 motor. For people who desire more power, there is the GT C Roadster, which offers 550 horsepower and 502 lb-ft of torque from the same engine.

The GT Roadster and the GT C Roadster, both are the perfect examples of brilliant automotive engineering. Although the performance isn't Porsche rivaling, the luxury is second to none. The GT Roadster, with its gorgeous lines, a stonking twin-turbo V-8 engine, and loads of grip, is just as capable as it is sexy, a very ravishing combination.

The GT Roadster and the GT C Roadster, both are the perfect examples of brilliant automotive engineering. Although the performance isn’t Porsche rivaling, the luxury is second to none. The GT Roadster, with its gorgeous lines, a stonking twin-turbo V-8 engine, and loads of grip, is just as capable as it is sexy, a very ravishing combination.

Features

8.9/10

The GT Roadster get a lot of equipment for that money, which helps it become a really lucrative option in the segment. The large 19-wheels and a multitude of gadgets inside the cabin are all on offer in the base model, which is priced at $124,400, while the GT C Roadster will set you back by $157,000.

The engine is the same 4-liter V-8 unit on both the trims, producing 469 horsepower and 465 lb-ft of torque in the base variant, and 550 horsepower and 502 lb-ft of torque on the more premium GT C variant. The aforementioned multitude of gadget also includes an old-school mechanical slip differential, which helps the car burn rubber on the racetrack, a requirement for all enthusiasts.

Features of GT Roadster Plus:

  • Standard Dynamic Plus package, which adds stiffer engine and transmission mounts and widens the power delivery

We Recommend

It can be easily seen that $32,600 price difference between the two trims is not easily justifiable, especially because the base trim offers everything you might need from big luxury Grand Tourer car. The more expensive 2018 Mercedes-Benz AMG-GT C Roadster does offer better performance, but the base model is the choice of pick.

Engine

9.6/10

Even this base delivers blazing speed, but it doesn’t have the panache of rivals like the Jaguar F-Type. The GT’s engine produces a respectable growl, however, and it gets better with the optional performance exhaust. The GT C Roadster meanwhile, feels substantially quicker than the lower trims. It’s ready to run whether you’re taking off from a stoplight or passing on the highway. -cars.usnews.com

Engine and transmission

The Mercedes-Benz AMG-GT Roadster has the same engine and transmission combo on both the trims, a twin- turbo 4-liter V-8 with 7-speed dual-clutch automatic gearbox, although the AMG-GT C gets it in a higher state of tune. The base GT churns out 469 horsepower and 465 lb-ft of torque while the GT C bumps up the power to 550 horsepower and 502 lb-ft of torque from that V-8 engine.

The rear wheel drive configuration helps the GT be great fun to drive and the base model GT is a perfect highway tool as it is, although it would fall a little behind on the track. The Mercedes-Benz AMG GT C feels like the perfect track tool, and an experienced driver can have loads of fun in the car.

Acceleration

As AMG is the performance division of Mercedes-Benz, its performance cannot be anything short of impressive. It is a really quick car, taking 3.9 seconds to reach to 60 mph, while the quarter-mile run takes a little more than 11 seconds. Not only that, but the GT is also a very environment-friendly, emitting less than 10 tons of carbon dioxide annually into the atmosphere.

The Nissan GTR is a legendary car, known for its brutal acceleration. It takes 2.9 seconds to reach 60 mph, which is incomprehensible. Its acceleration is so rapid, that some drivers even experience nausea when they put their foot down. The R8 and the F-type tie for second place, managing to inch ahead of the AMG-GT by a mere 0.4 seconds.

Braking and Handling

Mercedes also put some really impressive set of brakes in the GT for some great braking performance. Both the front and the rear are 14.2-inch disks, which along with the grippy tires make the car come to a halt from 60 mph in just 96 feet. There is also the optional carbon- ceramics brakes which help the car reduce the distance even further, but the figures aren’t available for it.

The handling of the car is a territory where it shines, with stiffly sprung suspension, wide track, limited slip differential, and other such features helping improve the handling. It handles itself with extreme grace and poise, while also feeling extremely planted and stable on the road. The roadster doesn’t roll, even under heavy cornering, and the electronics onboard help you keep the car pointed in the correct direction. Switch those off, and you can leave tire marks all around the racetrack if you wish to. In terms of handling, the GT is a winner.

Fuel Economy

6.2/10

AMG cars have never bothered with the fuel efficiency in the past. But with the fossil fuel reserves running out and global oil prices rising, even the big players have to factor in the efficiency of their cars. The Mercedes manages to squeeze 16 miles in the city and 21 miles on the highway, both in a single gallon of gasoline. This brings the overall efficiency of the car to 18 miles to a gallon, which is extremely impressive considering that the GT is a big heavy car with a big heavy V8 motor.

Model Mercedes-Benz AMG-GT Nissan GT-R Audi R8 Jaguar F-Type SVR
MPG (city) 16 16 14 15
MPG (highway) 21 22 22 23
MPG (combined) 18 18 17 18

The Nissan manages similar fuel efficiency figures as the Merc, which comes as no surprise. On the other hand, Audi is lower in efficiency, due to its poor mileage in the city. Jaguar is thirstier in the city run than the AMG, but more economical on the highway, which brings it to the same figure as the GT overall.

Interior

9.1/10

The 2018 Mercedes-AMG GT has a sleek, attractive cabin that uses plenty of top-quality materials. The confines are a bit snug, as this is a two-seater, but the seats are reasonably spacious. There’s a decent features list, though rivals have more connectivity options. Trunk space is adequate for the class. cars.usnews.com

Seating and Comfort

The AMG-GT is a two-seater, with gorgeous interiors, which incorporate beautiful materials that are soft to touch, and high contrast white thread on black leather stitching on the inside. Its steering wheel houses infotainment controls and has paddle shifters behind it. Overall, The Mercedes is a winner.

N/A 26.4/50.0/26.4 N/A N/A

Nissan houses four passengers and is the only car in this comparison to do so, which earns it practicality points. The Audi and Jaguar only seats two, just like the Mercedes. Although none of them feel cramped in any way, Nissan’s ability to seat four secures it a victory here.

Weight distribution

Managing a near perfect balance between the front and the back is the reason why the AMG-GT has such beautiful and graceful handling. Even though the car has a front engine configuration, the car is weighted more on the rear axle.

Model Mercedes AMG-GT Nissan GT-R Audi R8 Jaguar F-Type SVR
Weight % (Front) 47 54 44 52
Weight % (Rear) 53 46 56 48

The Nissan GT-R is a front engine car, has slightly more weight in the front than in the back whereas Audi is a mid-engine car and thus has slightly more weight on the rear axle. Jaguar has near perfect distribution, almost the same amount of weight on the axles, the front, and the rear.

Infotainment System

All AMG GTs utilize Mercedes-Benz’s familiar COMAND infotainment system featuring the following:

  • 8.4-inch central display and
  • console-mounted touchpad with a rotary scrolling knob
  • onboard Wi-Fi with a 4G LTE data connection

Cargo volume

Due to its folding roof, the roadster's cargo volume is a bit compromised. Even with the roof is up, the GT is not the car you would take for an airport run. There is enough space in the trunk for one big bag, or two if you aren’t carrying anything fragile, but that’s it. By sports car standards, that is enough space to help it win.

Volume (cube ft.) 10.1 8.8 8.0 14.4

The F-type suddenly emerges victorious as it has the most spacious boot around here, with the Nissan losing a little on boot space owing to its rear seats. The Audi shoves its big engine in the behind of the car and thus has to use the space under the hood for cargo, which is extremely disappointing.

Exterior

9.6/10

A long hood underscores the fact that the AMG GT’s V-8 is mounted aft of the front axle. Up front, big headlights sweep back into the fenders. A vertical grille is a direct link to Mercedes’ early and mid-century racing cars—especially the Panamericana cars of the early 1950s. Order your AMG GT in silver and you’ll understand. thecarconnection

Dimensions and weight

The Mercedes-Benz AMG-GT is a heavy car, and much of that weight is spread evenly throughout its very huge body. It is a long car, 179 inches long, and a wide car too, covering 76 inches sideways. With the curb weight of 3682 pounds, including a full tank of gas, and all the fluids like engine oil and coolant etc. being present. The track width is the widest in the segment and helps extract the maximum grip from the tires.

Track width(in) F/R 66.1/65.0 62.6/63.3 64.5/63.0 63/65

Nissan is the most tech advanced car in this segment, which makes it the heaviest car in this comparison. It is also the longest, as it seats four people instead of two like the others. Audi and the Jaguar are smaller and lighter than the others, which helps improve their handling.

Exterior features

Mercedes-Benz AMG-GT is one of the beautifully crafted cars ever. Some of its standard features are:

  • Bulbous headlamps with Daytime running LEDs
  • The long flowing bonnet
  • Drop top convertible looks
  • LED Taillight

Safety

Neither the NHTSA nor the IIHS has rated the car yet, which is probably due to the unavailability of enough test cars to perform all the safety tests, but it won’t take long it gets rated. Given the reputation of Mercedes-Benz, it would be an insult to doubt if the safety rating would anything less than the best.

Safety Features

Standard safety features are -

  • Lane Departure Warning
  • Auto-Leveling Headlights
  • Blind Spot Monitor
  • Traction Control
  • Integrated Turn Signal Mirrors
  • Daytime Running Lights
  • Electronic Stability Control
  • Brake Assist

Competition

Mercedes Benz AMG GT Roadster Vs Nissan GT-R

The Godzilla used to be the underdog who beat everyone, the epitome of Japanese engineering, the sports car that shamed every supercar. That’s all in the past though, as the Nissan is now a bit too heavy and soft to be able to compete in the big leagues. It does manage to hold its own in the comparison though, and it must be stressed that if you aren’t buying the Mercedes, it should be because you’re buying the Nissan. One significant disadvantage the GT-R has is the brand value, as nobody prefers Nissan over an Audi or a Jaguar. We would recommend the AMG-GT over the Nissan.

Mercedes Benz AMG GT Roadster Vs Audi R8

The Audi R8 borrows tech form the Lamborghini Huracan, and it shows, sometimes for the better, sometimes for the worst. The Audi doesn’t have the same passion that the others do and ends up feeling like a cut-price Lambo, which hurts its own brand image a little. We suggest the AMG-GT over the Audi.

Mercedes Benz AMG GT Roadster Vs Jaguar F-Type SVR

The Jaguar offers better performance than the Mercedes for nearly the same price but loses out on the luxury and equipment the German manufacturer offers. Its infotainment system is weak, the navigation isn’t nearly as good, and the ride quality is utterly backbone shattering hard and uncomfortable. Its the AMG-GT which wins this one.

Final Verdict

The Mercedes-Benz AMG-GT is the car that you should buy if you wish to satisfy your inner sports car enthusiast. It offers the perfect jack-of-all-trades middle ground approach, with the perfect blend of sportiness, comfort, driving a pleasure, sexy looks, and a blaring exhaust that will make the traffic stop even when not at a red light.

For the perfect price of $124,400, the GT is a great choice for your garage, although we may insist that if, by any chance, you have $157,000 lying around to spend, then go for the GT C Roadster. Even though the price difference is huge, the increase in power you get for the premium will put a wide grin on your face every time you decide to take a weekend drive.
