( http://www.TFLcar.com ) What's the most fun hybrid or eco car to drive? It certainly isn't the Toyota Prius, but it could very well be the 2011 Hyundai Sonata Hybrid or the 2011 Chevy Cruze Eco with the manual transmission. Both cars get 40 or more MPG on the highway and both cars are fun to drive...at least as fun as high mileage cars can be. So which one is the better car. Check out this first drive review.
