The D-Segment model is Kia’s first US market hybrid. Powered by a 2.4 litre engine with a Kia-developed parallel hybrid powertrain, it is capable of travelling at up to 62mph on electric power alone. With a combined 207bhp and 195lb-ft it’ll also sprint to 62mph in 9.2 seconds, topping out at 121mph.

Unlike Toyota’s hybrids, which use nickel-metal hydride batteries, the Optima uses a lithium polymer battery pack, offering 20-30 per cent less weight, 40 per cent less volume and 10 per cent better efficiency. They also hold their charge 25 per cent longer.

Byung Mo Ahn, group president and CEO, KMA and Kia Motors Manufacturing Georgia commented: ‘With a starting price under $27,000, the Optima Hybrid provides fuel-conscious shoppers with an outstanding value proposition by being priced below nearly all midsize hybrid competitors and delivering class-leading fuel economy along with head-turning style and advanced technologies.’

A 2.0-litre version is due in Europe in 2012, as part of the Optima range which arrives later this year, which Kia claims will be the most economical car in its sector. European pricing has not been announced yet.
