MPG-o-Matic Volvo C30 Review Summary: The Volvo C30 is a distinctively styled three-door hatchback that competes with the Audi A3, Mazda Speed 3, Mini Cooper S, Subaru WRX, Volkswagen GTI, and R32.
The EPA gas mileage estimates for the 2008 Volvo C30 come in at 19 city / 27 highway, when equipped with the automatic transmission. Over a number of days of driving, we found those estimates to be a tad low, as we achieved 27.5 miles per gallon in combined driving in twenty to thirty degree weather.
