Kia may implement all-wheel drive systems in the Optima, Sedona, and Niro, Kia Motors America’s vice president of Planning and Strategy says. Speaking with Car Buzz at the New York Auto Show, Orth Hedrick said the South Korean automaker is actively studying all-wheel drive options for the three vehicles.

Adding all-wheel drive to these models won’t be as easy as dropping in a rear differential. Instead, all-wheel drive Sedona and Optima models would need entirely new platforms meaning they won’t see the light of day in the vehicles current generations.

Despite the Niro being a crossover, Kia decided against launching it with all-wheel drive because it wanted to “do something different” and “the link between CUV and all-wheel drive wasn’t quite there yet.”
