The 2008 Infiniti G37 Coupe makes sense for someone seeking a rear-drive coupe with six-cylinder power and an automatic gearbox. Its 20 MPG combined rating is the key ownership number, while the 18 MPG city result shows where fuel use rises. Highway driving reaches 24 MPG. The EPA estimates $4,100 in yearly fuel expense and lists 444.35 grams of CO2 per mile. Those costs should be part of the decision alongside the drivetrain and body style.
