2017 Mercedes-Benz AMG GT Roadster (R190) Dimensions, Size & Specs

The curb weight of the Mercedes-AMG GT Roadster (R190) varies between 1595 kg and 1660 kg (approximately 3516 to 3661 lbs), depending on specific trim levels and optional equipment. The maximum permissible weight reaches up to 1940 kg (about 4277 lbs). This weight range reflects its balance between lightweight construction for performance and the substantial equipment and safety features expected in a premium roadster.

The luggage capacity of the AMG GT Roadster (R190) is relatively modest at 165 liters (about 5.8 cubic feet). As a two-seater sports convertible, the storage space is limited, making it suitable for small bags or light luggage. While not ideal for long trips requiring significant cargo, it suffices for daily use, weekend getaways, or city driving where minimal cargo space is needed.

The AMG GT Roadster (R190) has a ground clearance of 96 mm (approximately 3.78 inches), which is quite low. This low ride height benefits handling and aerodynamics, enhancing the car’s sporty performance and cornering capability. However, it also means drivers must be cautious when navigating speed bumps, steep driveways, or rough roads, as the car is susceptible to scraping the underbody.

The AMG GT Roadster offers wheel sizes of 19 and 20 inches, paired with high-performance tires. Tire sizes include 255/35 ZR19 and 295/35 ZR19 for the 19-inch wheels, and 265/35 ZR19 or 305/30 ZR20 for the 20-inch wheels. These tire options underline the car’s focus on high grip and dynamic handling, suitable for spirited driving and track use.

Yes, the Mercedes-AMG GT Roadster (R190) generally fits into a standard residential garage. Standard garages typically have a width of about 2400 mm (94.5 inches) or more and height clearance above 2000 mm (78.7 inches). With a width of 1939 mm (76.3 inches) excluding mirrors and a height around 1260 mm (49.6 inches), it fits comfortably inside. However, mirror width extends to 2075 mm (81.7 inches), so care is needed when opening mirrors or maneuvering in narrow garages.

Compared to its predecessor, the Mercedes-Benz SLS AMG Roadster, the AMG GT Roadster (R190) is somewhat more compact. The SLS AMG Roadster is longer at around 4643 mm (182.8 inches) and slightly wider, giving the AMG GT a more agile and nimble footprint. While the SLS commands more presence with its grand touring proportions, the AMG GT’s smaller dimensions allow for easier urban maneuvering and a sportier driving dynamic with reduced weight and improved aerodynamics.

The AMG GT Roadster (R190) is broadly similar in footprint to other high-performance roadsters such as the Porsche 911 Cabriolet. The AMG GT’s length of approximately 4545 mm (179 inches) and width around 1939 mm (76.3 inches) are competitive with the Porsche 911 Cabriolet, which measures roughly 4519 mm (177.8 inches) long and about 1852 mm (72.9 inches) wide. While the AMG GT is wider, which can improve handling stability, the Porsche tends to be lower and more compact, favoring nimble urban driving. Both cars target a similar sporty, luxury roadster market but differ slightly in their dimension focus.

While specific interior dimensions for the AMG GT Roadster (R190) cabin are not publicly detailed, its compact exterior size and sporty design prioritize driver engagement over spaciousness. The two-seat layout ensures a snug environment typical for high-performance roadsters, with limited rear passenger space (none in this case) and moderate headroom and legroom. Its low roofline (1260 mm / 49.6 inches height) and tight cockpit promote an immersive driving experience but may feel restrictive for taller occupants during long drives.

The dimensions of the AMG GT Roadster, including its low height of approximately 1260 mm (49.6 inches) and wide stance of 1939 mm (76.3 inches), contribute significantly to its aerodynamic efficiency and high-speed stability. The car's sculpted body and low ride height reduce air resistance, while the broad track width enhances cornering grip. These aerodynamic advantages, combined with lightweight construction and a powerful engine, allow the AMG GT Roadster to achieve exceptional speed, responsiveness, and driving precision, making it a standout performer in the roadster segment.
