Mercedes-AMG GT Roadster
Mercedes-Benz debuted two new high-performance convertibles in Paris on the eve of the Paris Motor Show: the 2018 Mercedes-AMG GT Roadster and 2018 Mercedes-AMG GT C Roadster — both scheduled to go on sale in the fall of 2017. Following the debut of the top-level 577-horsepower AMG GT R coupe — which is scheduled to arrive in the U.S. market by the middle of next year — Mercedes will add the two roadsters to complete the lineup.
With a boost in power over the AMG GT coupe, the 2018 AMG GT Roadster gets its motivation from a 4.0- liter biturbo V8 engine that produces 469 horsepower and 465 lb-ft of torque. The AMG GT C Roadster slots between the AMG GT Roadster and the AMG GT R with a new version of the 4.0-liter liter biturbo V8 engine producing 550 horsepower and 502 lb-ft of torque.
Both AMG GT Roadsters utilize the AMG SPEEDSHIFT DCT 7-speed dual-clutch transmission to optimize performance. The AMG GT Roadster accelerates from zero to 60 mph in just 3.9 seconds, while the AMG GT C Roadster makes the sprint in just 3.7 seconds. Top track speed for the AMG GT Roadster is 188 mph, and the AMG GT C tops out at 196 mph.
The new AMG GT roadsters are constructed with a lightweight, rigid aluminum body over a lightweight magnesium / steel / aluminum frame to save weight and keep the car’s center of gravity low. The fabric soft-top is available in three colors — black, red or beige — and can be opened or closed automatically in around 11 seconds at speeds up to 31 mph.
The AMG GT C receives technology from the AMG GT R, including active rear-axle steering and an electronically-controlled locking rear differential. Wider rear fenders permit a wider rear track (the distance between the wheels) and wider wheels, which improve traction and cornering speeds. AMG Sport Suspension is standard, and the AMG GT C includes AMG RIDE CONTROL Sport Suspension with adaptive, adjustable damping.
Active Air Management
Both the AMG GT Roadster and the AMG GT C Roadster receive the active air management system from the AMG GT R. Electrically-controlled vertical louvers behind the front fascia open and close to maximize engine cooling. During normal driving the louvers stay closed for more aerodynamic efficiency, and then automatically open when additional cooling is needed.
Aggressive Performance Design
The long hood and wide rear end give the AMG GT Roadster an aggressive, purposeful look, dominated by the prominent AMG Panamericana grille at the front that features 15 chrome-plated vertical bars. The new front bumper accentuates the width of the car, incorporating large air inlets to control cooling and aerodynamics.
Inside, the roadsters’ design follows similar lines of the exterior with a high beltline and dashboard adding to the feeling of the width in the car. The driver sits nestled in the cockpit with a low seating position and a sweeping center console. A new, light-colored interior is offered in Macchiato Beige with exclusive Nappa leather.
