The 2018 Mercedes-AMG GT C Roadster already sits in a special place within the AMG GT lineup, blending the open-air character of the Roadster with the wider bodywork, rear-wheel steering, and added performance hardware of the GT C. Showing 36,372 miles, this example takes that formula considerably further with a Weistec turbocharger upgrade, Weistec water/methanol injection system, BlackBoost cold air intake, aftermarket ECU tune, downpipes, exhaust, suspension setup, and aftermarket wheels. Finished in designo Diamond White Metallic over Saddle Brown Exclusive Nappa leather, it combines a distinctive factory specification with a heavily upgraded powertrain aimed at enthusiasts looking for substantially more than a stock GT C.
Exterior and Interior
The exterior of this 2018 Mercedes-AMG GT C Roadster is finished in designo Diamond White Metallic and paired with a black convertible soft top. The AMG Exterior Night Package adds darker exterior detailing, while the aftermarket wheels and suspension setup give the car a more aggressive stance than a standard example. Its modified appearance is matched by the underlying performance upgrades, with aftermarket downpipes and an exhaust system complementing the changes made under the hood. The interior of this 2018 Mercedes-AMG GT C Roadster is trimmed in Saddle Brown Exclusive Nappa leather and features AMG Matte Carbon Fiber interior trim, a Full DINAMICA AMG Performance steering wheel, and a Black DINAMICA headliner. The Burmester High-End Surround Sound System adds a premium audio experience, while DISTRONIC PLUS brings an additional level of long-distance convenience. Aftermarket floor mats are also fitted, rounding out a cabin that maintains the upscale GT C atmosphere while matching the car’s more performance-focused character.
Engine
At the heart of this 2018 Mercedes-AMG GT C Roadster is AMG’s 4.0L twin-turbocharged V8 paired with a 7-speed AMG SPEEDSHIFT dual-clutch automatic transmission and rear-wheel drive. This example has been significantly upgraded with Weistec turbochargers, a Weistec heat shield, Weistec water/methanol injection, a BlackBoost cold air intake system, an aftermarket ECU tune, aftermarket downpipes, and an aftermarket exhaust system. Together, these modifications transform the already potent M178-powered GT C into a much more serious performance build, with the water/methanol system and supporting airflow upgrades designed to complement the increased demands of the upgraded turbochargers. For an enthusiast seeking a modified AMG that retains the character and theater of the factory GT C while delivering a more aggressive powertrain setup, this example brings together an especially compelling combination of hardware.
