The 2008 Cars.com Mileage Challenge
As the price for a gallon of regular gas hovers above $3 a gallon — $3.40 in California — it’s high time we investigate what sort of mileage our cars achieve in the real world. In October, the EPA released its 2008 Fuel Economy Guide, which rates mileage using stricter standards for acceleration, air-conditioning use, cold weather and top speeds than were used in the past. The new measures purportedly reflect real-world driving better than before; MPG ratings dropped some 5 to 15 percent per car using the new standards.
Still, the EPA tests are done in laboratories, not on the road. To test real-world mileage, we took four cars across interstates and rural roads between Chicago and Madison, Wis., in October. Nine hours, two pit stops and one greasy lunch later, we had logged some 300 miles.
