Its new generation 3.5-liter twin-turbo V-6 makes more power than many of Ford’s older big block V-8s.During a recent auto industry conference in Traverse City, Mich., Chris Grundler, director of the EPA’s office of transportation and air quality, said the agency recognizes fuels have a role to play in enabling automakers to meet tougher fuel economy and emissions regulations.
The octane in American gasoline is calculated differently and is the average of the RON and MON (motor octane number).The final standards were developed by DOT’s National Highway Traffic Safety Administration (NHTSA) and EPA following extensive engagement with automakers, the United Auto Workers, consumer groups, environmental and energy experts, states, and the public.Last year, 13 major automakers, which together account for more than 90 percent of all vehicles sold in the United States, announced their support for the new standards.Premium fuel costs around 53 cents more per gallon than regular in many parts of the country -- a fact that has many motorists grumbling.Automakers don’t want to force higher fuel prices on their customers.You might think that adding octane is just a simple matter of dumping more ethanol into the mix. While adding ethanol does bump up octane, it also lowers fuel economy because the ethanol that replaces gasoline is less energy dense.
Also, higher concentrations of ethanol require automakers to make changes to fuel systems.
You can bet the situation will be a combustible one.
WASHINGTON, DC – The Obama Administration today finalized groundbreaking standards that will increase fuel economy to the equivalent of 54.5 mpg for cars and light-duty trucks by Model Year 2025.
By aligning Federal and state requirements and providing manufacturers with long-term regulatory certainty and compliance flexibility, the standards encourage investments in clean, innovative technologies that will benefit families, promote U. leadership in the automotive sector, and curb pollution.
“Simply put, this groundbreaking program will result in vehicles that use less gas, travel farther, and provide more efficiency for consumers than ever before—all while protecting the air we breathe and giving automakers the regulatory certainty to build the cars of the future here in America,” said Transportation Secretary Ray La Hood.
