Product Overview

Mercedes-AMG GT Roadster R190 is a compact convertible sports car in production from 2017 to 2021. It was available with several tunes of the M178 bi-turbo hot-V8 engine that displaced 4.0 liters.
Compared to the SLS AMG that preceded it, the AMG GT is less exclusive and is notably more compact. However, it offers decidedly superior performance. While its engine is more advanced, the AMG GT has also proved to be more reliable.
Owners may find that at speed the vehicle consumes a lot more than the numbers indicate, thanks to a disappointing 0.38 coefficient of drag to show for it. Utility-minded owners will likely need to keep an alternative for hauling things around, as the tiny cargo space is almost surely insufficient.

Sentiment Score 69%
Reviewers from carwow have found the following***:
Mercedes-AMG GT Roadster is a fun, agile open-top that both looks and sounds brilliant. However, it's less practical than alternatives like the Porsche 911 Cabriolet and Audi R8 Spyder. All three trims come with the same four-litre, twin-turbocharged, petrol V8. The top-spec GT C is the gutsiest, with 557hp.
