Kia

As part of Hyundai, Kia has the Optima Hybrid which shares elements with the Hyundai Sonata Hybrid. The Korean automaker has also shown hybrid concepts of various sorts. Unlike Hyundai which is bullish on fuel cells, and not big on EVs, Kia may be playing good cop to the bad cop (or is it the other way around?) and is preparing its first global electric car, the Soul EV. No diesels are offered, but Kia’s overall mpg score for a manufacturers entire line of vehicles is high, as it has no trucks or guzzlers.
