According to WebMD, swollen ankles commonly occur when a person stands or walks a lot, but if swollen ankles persist or are accompanied by other symptoms, they could be an indication of a serious health problem, such as pregnancy complications, foot or ankle injury, lymphedema and venous insufficiency.
The Chevy Malibu can get between 17 and 22 miles per gallon of gas on the road. It could even get to 26 to 33 miles per galon if you are in a highway.
Assuming the Volt is operated 80 percent of the time in EV mode, and 20 percent in gas, for 12,000 miles annual usage, it would run the gas engine for just 2,400 of those miles. At 41 mpg, this is 58.5 gallons of gas. By contrast a Malibu Hybrid at 47 mpg would burn 255 gallons.
