2011 Chevrolet Malibu LT1 4dr Sedan (2.4L 4cyl 6A)
I purchased My Malibu to save money on fuel, and have a comfortable ride. My first stop for gas netted me over 32MPG. This car is very comfortable for me (6'3" and over 280lbs), although the door opening could be a little larger.
I am finding the 2.4 4cyl engine to be adequate, but if you want the good MPG, you need to drive it light there is an egg between your foot and the gas pedal.
My favorite things are the stereo and the 6 speed automatic transmission! It's very smooth shifting, and does a good job keeping the engine in an efficient RPM range. I also love the remote start feature on our cold Minnesota mornings.
