Who it suits. Drivers wanting a rear-wheel-drive Infiniti coupe Buyers who prioritize highway travel over city mileage Shoppers budgeting with EPA fuel figures

The 2013 Infiniti G37 Coupe makes sense for a buyer focused on a rear-wheel-drive gasoline car with a six-cylinder engine and automatic transmission. Its 22 combined MPG is straightforward to budget, but the EPA’s $3,750 annual fuel-cost estimate is a major part of ownership planning. Highway use is rated at 26 MPG, while city use falls to 19 MPG. That split matters if most of your miles are urban. Its 411 grams of CO2 per mile also gives the car a clear emissions trade-off.
