起亚在本届巴黎车展发布了Optima T-Hybrid概念车。这款轻混概念车结合了一台1.7升四缸CRDi涡轮柴油引擎和一台电机，输出功率提升15-20%。而标准版柴油引擎还配备了电动机械增压器，在整个有效转速内都可提供更强劲动力，特别是在低转速情况下，功率提升更明显，尤其是扭矩输出更强劲。该车还配备48伏铅碳电池，可以在车辆低速行驶时只依靠电机驱动前行。在加速过程中电机可将产生的电能传递给电池，而无需像锂电池组那样激活冷却系统。该车还配备停启系统和新的皮带轮驱动起动器发电机，可大幅降低引擎起动时产生的噪音和震动。这款概念车除了动力比标准版更强劲外，油耗和二氧化碳排放量也大幅降低。不过，这款概念车并未开发完成，因此起亚不会推出量产版。

 

Kia Optima T-Hybrid diesel-electric concept introduced in Paris with electric supercharger

Kia has unveiled at Paris Motor Show the interesting Optima T-Hybrid concept.

 

The mild hybrid Optima concept combines the standard 1.7-liter four-cylinder CRDi turbodiesel engine with an electric motor which has bumped output by 15-20 percent. The conventional engine has been equipped with an electric supercharger providing more power in the entire rpm range but especially at low engine speeds when the vehicle benefits from extra torque.

 

There's also a 48V lead-carbon battery allowing the concept to be driven only on the power provided by the electric motor at low speeds. During deceleration, the generated energy is transferred to the battery pack which does not need active cooling compared to the usual lithium-ion batteries. Other changes include a stop/start system and a new belt-driven starter generator which significantly decreases the noise and vibration generated during the engine's start.

 

Aside from packing more punch than the regular Optima, the T-Hybrid concept also provides a "significant reduction" in both fuel consumption and CO2 figures. However, the concept is still being developed so a production version is not on the agenda yet.
