Kia Motors recently unveiled the all-new 2017 Optima Plug-in Hybrid (PHEV) at the Chicago Auto Show. Kia’s first PHEV joined two other fuel-efficient additions to the brand’s growing line-up of eco-friendly vehicles, including the all-new 2017 Niro Hybrid Utility Vehicle (HUV) and all-new 2017 Optima Hybrid (HEV), all three of which are being introduced under the Kia Motors EcoDynamics environmentally friendly sub-brand.
The all-new 2017 Optima PHEV was engineered with a dual focus on efficiency and driving dynamics. Utilizing Kia’s highly efficient 2.0-liter “Nu” four-cylinder GDI (Gasoline Direct Injection) engine, mated to a six-speed automatic transmission, power output is targeted for a class-leading 154 hp @ 6,000 rpm. Electric power is produced by a transmission-mounted 50 kW motor, which is 42 percent more powerful than in the previous Optima Hybrid to allow for greater all-electric capability.
With an estimated 600 miles of total driving range, the Optima PHEV’s next-generation battery system features a 9.8 kWh lithium-ion polymer battery pack, which produces roughly 60 percent more energy output than the battery pack found in the outgoing Optima’s hybrid system, and is estimated to achieve 27 miles in full EV mode, placing the Optima PHEV among the segment leaders in all-electric range. Additional power to the battery system is generated from the vehicle’s improved Regenerative Braking System, which maximizes regenerative torque through refined cooperative control between the hybrid control unit and the brake actuation unit, resulting in a 10 percent increase in regenerative energy. The Optima PHEV is equipped with a single charging port conveniently located in the driver’s side front fender. A full charge can be achieved in less-than three hours via a 240V (Level 2) charger, and less-than nine hours via a 120V (Level 1) charger. The all-new Optima PHEV provides its driver with options to reserve electric range via a plug-in hybrid mode select system.
Exclusive to the PHEV variant of the all-new Optima, the system includes an all-Electric Mode (EV), which is suitable for short-range city driving, Hybrid Mode (HEV) for highway driving, and Charging Mode, which increases energy direction to the battery while driving at higher speeds. The energy produced while in Charging Mode can then be utilized in EV mode, extending the convenience of full electric power without stopping to charge. All-new Eco-DAS (Driver Assistance System) features Kia’s first application of Coasting Guide. This feature aims at maximizing fuel economy by essentially coaching the driver on when to coast and brake via an icon in the Instrument Panel that blinks for four-seconds and sounds a one-time audible alert.
The Optima Plug-in Hybrid, available in one trim, EX, will be built at Hwasung, South Korea, and is expected to go on sale in the fourth quarter of this year. Pricing will be announced closer to the on-sale date.
