Mercedes has unveiled its new AMG GT Roadster in Paris. The open-top two-seater will be available in two model variants when it goes on sale in 2017. The base model is powered by a 476 bhp 4.0-litre V8 while the flagship AMG GT C Roadster is tuned to deliver even more horse power, resulting in a 0-62mph time of 3.7 seconds and top speed of 196mph. AMG RIDE CONTROL and a widened track help with high speed cornering and if it rains, the roof will close in 11 seconds at speeds of up to 31mph.
