起亚近日在芝加哥车展发布了2017款Optima混动和插电混动车型。这两款车采用了人们熟悉的设计，但配备了可变式进气启闭系统，改款前后保险杠和后散流器，LED前大灯，专属车标，空气动力学合金轮圈。车厢内变化不大，但采用了专属仪表群并额外增加软触内饰，提供了Eco Driver Assistance辅助驾驶系统，该系统集成巡航指导功能，可告诉驾驶员何时可以巡航行驶，何时该踩刹车。Optima混动版搭载一台2.0升GDI四缸引擎，一台电机和1.62千瓦时锂电池组，车辆综合输出功率193马力，综合油耗42英里/加仑（百公里油耗约合5.6升）。而Optima插电混动版搭载一台2.0升GDI四缸引擎，动力更强劲电机和9.8千瓦时锂电池组，综合功率202马力。该车在纯电动模式下可行驶27英里（约合43公里），整体续航里程600英里（约合965公里）。在电池电量耗尽后，如果采用240伏Level 2电源，完全充满电不到3小时；如果采用120伏Level 1电源，充电时间不到9小时。
2017 Kia Optima Hybrid & Optima Plug-in Hybrid unveiled
Kia has introduced the 2017 Optima Hybrid and Optima Plug-in Hybrid at the Chicago Auto Show.
Designed to appeal to eco-conscious buyers, the models have a familiar design but are distinguished by an active shutter grille, modified bumpers, and an aerodynamic rear diffuser. The cars have also been equipped with LED-infused headlights, special badging, and aerodynamic alloy wheels.
The interior largely carries over but the hybrid variants have unique instrumentation and additional soft-touch materials. The cars also have an Eco Driver Assistance System with a Coasting Guide that tells drivers when to coast and when to brake.
The Optima Hybrid is powered by an eco-friendly powertrain that consists of a 2.0-liter GDI four-cylinder engine, an electric motor, and a 1.62 kilowatt hour lithium-polymer battery. This enables the model to produce a combined output maximum output of 193 horsepower and return an estimated 42 mpg combined.
The Optima Plug-in Hybrid is largely identical but it features a plug-in hybrid powertrain that consists of a 2.0-liter GDI four-cylinder, a more powerful electric motor, and a larger 9.8 kWh lithium-ion battery pack. As a result, the Optima Plug-in Hybrid is slightly more powerful as it produces a combined maximum output of 202 hp. More importantly, the model can travel 27 miles on electricity alone and about 600 miles overall.
When the battery is depleted, it can be recharged in less than three hours with a 240 volt Level 2 charger. Those unfortunate enough to have a 120 volt Level 1 charger are in for a wait as the recharging process takes a little less than nine hours.
