In the video above from the Sundance Channel show, Big Ideas for a Small Planet, an Indy race car driver says he gets better mileage on ethanol. First he says racing can be green, that the car gets more power on ethanol and then he says he gets a lot better mileage. So much better mileage, in fact, they had to shrink the size of the fuel tank. Here is the exact quote: "First thing that we've noticed with the transition, from the ten percent to hundred percent ethanol this year, is that we have a broader power band and more torque. So the car is pulling better and accelerating better out of the corner. We also have gotten a lot better mileage, so we are reducing the size of the fuel cell from 30 gallons down to 22 gallons. We are out there testing this under the toughest conditions that we can and that's going to make better-performing cars that can run ethanol more efficiently out on the road." FYI, "fuel cell" in Indy race cars are just fuel tanks and have nothing to do with hydrogen fuel cells. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Study: Non-Flex-Fuel cars get better Fuel Economy on Ethanol The study was done with four 2007 model vehicles: a Toyota Camry, a Ford Fusion, and two Chevrolet Impalas (flex-fuel and non). The cars took the EPA Highway Fuel Economy Test (HWFET) on ethanol-gasoline blends and normal gasoline. The results found "fuel mixtures with more ethanol than E10 but less than E85 - can in some cases provide better fuel economy than regular unleaded gasoline, even in standard, non-flex-fuel vehicles." In fact, along with three out of four actually traveling further on ethanol, "all of the vehicles got better mileage with ethanol blends than the ethanol's energy content would predict." The study even showed there was no engine fault signs when normal cars used blends up to 65 percent. |
