It was only around three ago when Mercedes-AMG unveiled the AMG GT R Coupe. Now at the 2019 Geneva Motor Show, AMG chopped the roof the AMG GT R Coupe and made some necessary revisions. This resulted to the birth of a new AMG GT R model from Mercedes-Benz – the new Mercedes-AMG GT R Roadster.
When the AMG GT R Roadster arrives, the AMG GT family will have 16 members that include five two-door coupes, four roadsters, two customer sports racing cars and five 4-door coupes. But AMG isn't planning to build many as only 750 units are intended to be produced.
Of course, the main difference between the AMG GT R Coupe and AMG GT R Roadster is that the latter has no fixed roof, allowing its occupants to enjoy the thrill of open-air ride. But should they need some protection from the elements, the AMG GT R Roadster is provided with a three-layered fabric soft top. Featuring an inserted acoustic mat that can reduce noise, this soft top is supported by a structure of low weight – thanks to materials such as magnesium, steel and aluminum – which basically help give the AMG GT R Roadster a low center of gravity.
The new AMG GT R Roadster is now offered with a new a new exclusive color shade – a fine designo graphite grey magno matt finish. This means that the color palette for the AMG GT R now include 14 hues.
Serving as the core of the AMG GT R Roadster is the AMG 4.0-liter V8 biturbo engine that is able to deliver 430 kW (585 hp) of max output and 700 Nm of torque. With this amount of power on hand, the AMG GT R Roadster can accelerate as quick as the as AMG GT R Coupe, zooming from zero to 100 km/h in 3.6 just seconds. Its top speed is just 1 km/h slower than that of the AMG GT R Coupe, at 317 km/h. This was expected as the AMG GT R Roadster is heavier than the AMG GT R Coupe because of its roof system.
In terms of fuel consumption and emissions, the new AMG GT R Roadster eats up 12.4 liters of fuel per 100 km (combined) and emits 284 grams of carbon dioxide per km (combined).
Complementing this supreme engine power is a high-performance braking system. The AMG GT R Roadster comes fitted with a composite brake system that allows for superb deceleration and high fade-resistance. It includes internally ventilated and perforated brake discs that measure 390 mm on the front and 360 mm on the rear. It also includes brake calipers that are finished in yellow as standard. Nonetheless, customers may avail of ceramic high-performance composite brake system that is around 15 kg lighter than the standard system. It is also more durable and more fade resistant.
