Hyundai’s other concept car unveiled at the Seoul Motor Show alongside the Enduro crossover is the RM15, a mid-engined, lightweight race car.
Based on last year’s Veloster RM Concept, the RM15 (which stands for Racing Midship 2015) features advanced vehicle technologies and materials.
The Hyundai RM15 study has an aluminum core structure with carbon-fiber reinforced plastic (CFRP) body panels in order to reduce vehicle weight. The weight saving is significant compared to a conventional all-steel vehicle – 195 kg (430 lbs), with the RM15 tipping the scales at 1,260 kg (2,778 lbs).
Compared to the Veloster RM, the new RM15 also has a more evenly balanced weight distribution (43 percent front, 57 percent rear), with the center of gravity sitting just 491mm (19.3in) from the ground.
The study features a series of modifications that boost performance, handling and efficiency. For example, aerodynamic downforce is 24 kg (52.9lbs) at 200 km/h (124 mph), helped by a competitive lift-coefficient.
But the RM15’s highlight is the Theta 2.0-liter T-GDI turbocharged petrol engine mounted transversely behind the two-seater cabin and ahead of the rear axle. The four-cylinder unit produces 300PS (296hp) at 6,000 rpm and drives the rear wheels through a six-speed manual transmission. The engine also produces 383Nm (282lb-ft) of torque at 2,000, allowing the RM15 to sprint from 0 to 100 km/h (62 mph) in just 4.7 seconds.
The Hyundai RM15 study features an integrated sub-frame (front and rear), as well as a WRC-inspired roll-cage which add extra stiffness to the structure. The car rides on 19-inch mono block forged alloy wheels shod with 235/35 R19 tires (front) and 265/35 R19 tires (rear). The body panels sport the signature colors of the company’s “N” motorsport division, which are also featured on the Hyundai WRC i20 rally car.
