Despite all the hubbub about new electric and hybrid cars in 2010, Cars.com’s top award went to a gasoline-powered midsize family sedan – the 2011 Kia Optima. The Optima has outstanding fuel efficiency and is more fun to drive than its cousin the Hyundai Sonata. Combine that with a reasonable asking price and you’ll start to understand why the Optima is our Cars.com “Best of 2011.” For more details and to see our other nominees, check out our top post of the week.
