A key component to Kia Motors’ Green Car Roadmap was unveiled at the Chicago Auto Show today as Kia Motors America (KMA) hosted the global debut of the all-new 2017 Niro Hybrid Utility Vehicle (HUV). A no-compromise vehicle that combines driving enjoyment with eye-catching design, functional utility and hybrid efficiency, the all-new Niro strikes the perfect balance for today’s consumers and stakes claim to a unique position between the hybrid-electric vehicle and CUV segments.

Motivating the Niro is a highly efficient and engaging powertrain starting with an all-new, state-of-the-art Kappa 1.6-liter GDI four-cylinder engine, engineered specifically for hybrid applications. Making 103 horsepower, the new engine marks the first combination of the Atkinson Cycle, cooled exhaust gas recirculation (EGR), GDI and a long-stroke-narrow-bore specification to maximize efficiency2. Efficiency and emissions are further improved via the Niro’s exhaust heat recovery system, which speeds engine warm-up by routing coolant to a heat exchanger in the exhaust system. A 43-hp tractive motor, known as the transmission-mounted electric device (TMED), works in tandem with the gasoline engine to produce a robust 146 horsepower and 195 lb.-ft. of torque.

That power is transmitted through a newly developed, second-generation six-speed dual-clutch transmission (DCT), which not only boosts efficiency but is also a key factor to the Niro’s great driving experience. The transmission delivers smooth, quick shifts for a natural and spirited feel in stark contrast to that of other hybrids equipped with continuously variable transmissions. Bringing the whole system together is a compact and lightweight 1.56-kWh Lithium Ion Polymer battery located underneath the rear seat. Because the high-voltage battery is both power and energy dense, engineers were able to use the downsized gasoline engine to maximize fuel economy and reduce emissions.

With its unique combination of the lightweight TMED, proven GDI and Atkinson Cycle technology in the internal combustion engine, along with the DCT providing a dynamic driving experience, the Niro offers enjoyment and efficiency all in one, targeting a combined fuel efficiency rating of 50 mpg.

Driving Fun
The Niro’s parallel and simplified hybrid system creates seamless transitions of power delivered to the front wheels, resulting in a very un-hybrid-like driving experience. The hybrid system is neither intrusive nor obvious. The Niro accelerates quickly off the line and continues its smooth power delivery, inspiring driver confidence in everyday driving maneuvers like merging onto the highway.

Special attention was also paid to brake feel. Applying lessons learned through development of two generations of Optima Hybrids as well as the fully electric Soul EV, Kia engineers designed the Niro’s regenerative system to seamlessly blend in hydraulic friction braking. Consequently, deceleration feels more consistent and linear than other hybrids.
