2011 Kia Sedona receives an all-new 3.5-liter V6 engine capable of making up to 271 horsepower. That's 23 more horsepower than the previous 3.8-liter V6. A new six-speed automatic transmission replaces the old five-speed. This combination helps improve fuel mileage by two miles per gallon in the government's highway driving cycle. Also new are side mirror turn signal indicators. Now standard on all models, Bluetooth allows hands-free operation of most cellphones. A new, slightly revised grille, shared by other Kias, differentiates the 2011 from the 2010.
