The Enviro-meter:
There is one thing that bothers us about the C300 flex-fuel. Mercedes hasn't put any kind of flex-fuel/E85 compatible signage on the entire vehicle. Badges stuck to the body aren't necessary, but at the very least, some kind of sticker on the fuel door, or even a color-coded fuel cap would help the owner know/remember that he could put E85 in the tank. That would be helpful. At this point, the only mention of the car's dual-fuel status is in the owner's manual.
Here's how the 2008 Mercedes-Benz C300 Flex-fuels environmental impact tallies up, according to fueleconomy.gov:
- Petroleum Oil Consumption: 16.3 barrels of crude annually burning premium gasolinecompared to 5.3 barrels for E85.
- Greenhouse Gas Emissions: 8.7 tons/year on premium gasoline, where E85 totals 7.4 tons/year (driving an average of 15,000 miles per year).
- EPA Air Pollution Score: not available
