OREANDA-NEWS. February 15, 2016. Kia Motors America (KMA) today unveiled the 2017 Kia Optima Hybrid (HEV) at the Chicago Auto Show.  The Optima HEV enjoys the same full redesign – inside and out – as the conventional gas-powered model, the all-new fourth-generation Optima sedan, bringing with it a new hybrid powertrain that targets a 10 percent improvement in fuel economy over the outgoing model.  The enhanced HEV blends modern styling and a premium driving experience with an even more intense focus on efficiency and is being introduced under the Kia Motors EcoDynamics environmentally friendly sub-brand.

“Kia is pursuing a bold initiative to increase fuel efficiency by 25 percent across our entire model line-up by 2020, and new models like the Optima HEV and PHEV will be critical to realizing that vision,” said Orth Hedrick, vice president, product planning, KMA. “The brand’s commitment to sustainability, coupled with our history of delivering premium amenities and value, has never been more evident than in these all-new hybrid vehicles, which are world-class examples of green engineering, advanced technology and design.”

Enhanced Hybrid Performance
Targeting a 10 percent increase in fuel economy, the Optima Hybrid replaces the previous generation’s 2.4-liter engine with an efficient and compact 2.0-liter GDI four cylinder – estimated at 154 horsepower – coupled with a hybrid starter generator and tied to an upgraded, smooth-shifting six-speed transmission.  A 38 kW electric motor and clutch replaces the traditional torque converter to provide strong off-the-line acceleration and power assistance to the engine when necessary.  Energy flow is fast and seamless between EV mode and hybrid mode.  Total combined output for the Optima Hybrid is estimated at a robust 193 horsepower at 6,000 rpm.  Also adding to the equation is a new electric water pump and a new electric oil pump, which help improve overall fuel economy. 

Giving life to the electric motor is a more compact, lightweight, high-density lithium-polymer battery pack with a 13-percent increase in capacity to 1.62 kWh.  With improved packaging, this more potent energy source now fits neatly underneath the trunk floor without encroaching into cargo space.  The revised battery configuration results in a larger, more practical load area and allows the integration of 60/40 split-folding rear seats.
