The new 2016 Mercedes-AMG GT two-seater sports car, the second developed entirely in-house by Mercedes-AMG, has a 456 horsepower AMG 4.0-liter V8 biturbo engine and, the GT S model with 503 horsepower, and are mated to a seven-speed dual clutch transmission in a rear transaxle configuration. Various modes are available: "C" (Controlled Efficiency), "S" (Sport), "S+" (Sport Plus) and "I" (Individual). The manual "RACE" drive program, reserved exclusively for the GT S, optimally adjusts the shift strategy of the dual clutch transmission to the needs of racetrack usage. 0 - 60 mph is under 4 seconds for both variants and top speed around 190 mph. The U.S. will first launch the 2016 AMG GT S in the spring of 2015 and the AMG GT will launch in the following year.
