Hyundai Unveils Mid-Engine RM15 Concept at Seoul Motor Show
Hyundai Motor Company has revealed its latest mid-engined model, an aggressively-styled high-performance coupe concept named ‘RM15’ (Racing Midship 2015). The lightweight two-seat concept, unveiled today at the 11th Seoul Motor Show, makes a confident statement about Hyundai Motor’s passion for performance and its expertise in the development of advanced vehicle technologies.
The RM15 features an aluminum spaceframe as its core structure, with a covering of light, stiff body panels formed in carbon-fiber reinforced plastic (CFRP), which together help to achieve a significant weight saving compared to a conventional all-steel vehicle. The body panels are painted in the signature colors of the company’s ‘N’ (pale blue, black, red and Hyundai mid-blue) which also feature on the Hyundai WRC i20 rally car.
Based on the Veloster RM shown at last year’s Busan Motor Show in Korea, the new RM15 features a host of modifications that boost the latest model’s performance, handling and efficiency. Total weight is reduced (to 1,260 kg – a saving of 195kg compared to an all-steel structure), weight distribution is more evenly balanced (43% front, 57% rear), the center of gravity is just 491 mm from the ground and aerodynamic downforce is 24 kg at 200 kph, aided by a competitive lift-coefficient.
Power comes from Hyundai Motor’s Theta 2.0-liter T-GDI engine mounted transversely behind the two-seater cabin and ahead of the rear axle, ensuring optimized weight distribution and a low moment of inertia for excellent handling agility and high levels of traction. New, vertical air-intake slots in the flanks of the car, ahead of the rear wheel arches, increase cooling airflow within the engine bay and enhance powertrain efficiency.
The four-cylinder turbocharged gasoline engine generates 300 ps at 6,000 rpm and drives the rear wheels through a six-speed manual transmission. Strong torque delivery (39 kgm [383 Nm] at 2,000 rpm) helps to reduce the 0-100 km acceleration time to just 4.7 seconds.
