Environmental Comparison

E85 is often heralded as a way to reduce air pollution. Since increasing concern about global warming has focused attention on greenhouse gases, we decided to track our carbon emissions during this test.

By relating our observed fuel economy to CO2 emission figures found in the EPA's Green Vehicle Guide we determined that our gasoline round trip produced 706.5 pounds of carbon dioxide. On E85, the CO2emissions came to 703.1 pounds. The difference came out in E85's favor, but only by a scant 0.5 percent. Call it a tie. This is certainly not the reduction in greenhouse gas emissions we had been led to expect.



I've read this 2 years ago from Edmunds and never tried E85. And its less mpg for less gas price so more trips to the gas station. I still use regular gasoline and get 26mpg on the highway and 21-22 on the city. Not really that bad for a right sized SUV V6 with 283hp. Before I had a 4cyl 5seater SUV with only 140hp and I would get 20mpg on the highway and 15mpg city. The Journey feels like a hybrid compared to that.
