Hyundai RM15

The Hyundai RM15, short for Racing Midship 15, is a high-performance concept car first shown at the 2015 Frankfurt Motor Show and the second model of Hyundai Project RM. It keeps the mid-engine layout, engine and drivetrain of the RM14 and, like it, is based on the first-generation Veloster. The RM14 used a steel body, while the RM15 switched to an aluminium monocoque of 214 kg, 30 percent lighter than the steel one of 307.5 kg, and carbon fibre reinforced plastic outer panels of 33.7 kg instead of 77.2 kg. Overall it is 36 percent or 195 kg lighter, at a kerb weight of 1,260 kg against 1,455 kg for the RM14, despite a rear roll cage taken from a World Rally Championship car. New aerodynamics produce 124 kg of downforce at 200 km/h, and the radiator and cooling ducts were relocated.
