2018 Mercedes-Benz AMG® GT Roadster VS GT C Roadster

The Mercedes-Benz AMG® GT is one of the most iconic Mercedes-Benz vehicles in history. When you turn it into a roadster, you get one of the highest performing convertibles in the world. For 2018, The GT is available in two roadster variations. The base-model is the GT, leaving the GT C as the flagship GT roadster with more power and more capability. But what is it exactly that differs the 2018 Mercedes-Benz AMG® GT Roadster from the GT C Roadster? 

For starters, the engines are the exact same. They both feature the same 4.0L biturbo V8 engine that you will find in the GT Coupe, GT R, and even the Mercedes-Benz AMG® C 63 with a slightly different cooling system. The difference between the two versions in the GT and GT C Roadsters is the power output. Through special tuning, the GT C features 81 more horsepower than the GT Roadster, which also falls behind by 37 lb-ft of torque. Of course, this makes the GT C accelerate faster and reach a higher top speed, but that is not the reason why you will want to go all the way with the GT Roadster.

In a sense, the GT Roadster is the roadster variation of the GT S, while the GT C is the roadster variation of the GT R. We can say this with confidence because the GT C even has the same width rear-end as the GT R. This makes it more stable at high speeds and around corners, but it also makes it stronger in general. Especially when you combine this with the electronically-controlled differential, the GT Roadster falls further behind with its mechanical differential.  

To better control the wide-body beast, the GT C also features an extra transmission mode, known fondly as RACE Mode. It is not something you probably want to use on the street, but it doesn't come with the GT Roadster, so you can see why we need it.
