Kia K7/Cadenza Hybrid
Kia is getting ready to release a Hybrid version of the big K7 sedan. Known here as the Cadenza.
Not sure if it will make it to the US yet.
It seems to share the Optima Hybrid power train. Which includes a 150 2.4 Liter engine as well as a 35-kilowatt electric motor.
Over here, its only competition would deb the Toyota Avalon Hybrid.
