President Barack Obama released a final version of a rule forcing automakers to more than double average fuel economy by 2025 that includes changes benefiting Honda Motor Co. and other makers of alternative-fuel vehicles.

“By the middle of the next decade, our cars will get nearly 55 miles per gallon, almost double what they get today,” Obama said Tuesday in an e-mailed statement. “It’ll strengthen our nation’s energy security, it’s good for middle class families and it will help create an economy built to last.”

Corporate average fuel economy, or CAFE, rules released today and that took effect earlier this year are supposed to reduce U.S. oil consumption by 12 billion barrels and lead to fuel savings of more than $8,000 by 2025 over the life of a vehicle, the White House said. Boosting average fuel economy is part of Obama’s plan to reduce oil imports and use. Promoting purchases of more fuel-efficient vehicles can help reduce the use of fossil fuels.

The Environmental Protection Agency and National Highway Traffic Safety Administration released the proposed rule for model years 2017 to 2025 in November after reaching an agreement with automakers on the outline in July 2011. Auto executives from companies including General Motors Co., Ford Motor Co., Chrysler Group LLC and Hyundai Motor Co. stood with Obama at the Washington Convention Center to tout the agreement, which was the basis for the final rule.

The proposed rule granted incentives to plug-in electric and plug-in electric-hybrid vehicles, with the final rule adding natural-gas-powered cars to that list. Honda sells vehicles powered by natural gas.

$192 Billion

The 2025 rule and one that took effect this year and applies through 2016 could together cost as much as $192 billion, according to administration estimates. The administration has said the 2017-2025 rule would save as much as $515 billion in fuel spending as they add an average of $2,000 to the price of each new passenger vehicle by 2025.

The proposed rule required automakers to improve car fuel economy by an average of 5 percent annually and trucks’ by 3.5 percent in most years.

Obama had delayed release of the final version from a self- imposed Aug. 15 deadline. The proposed rule was criticized by Representative Darrell Issa, a California Republican, and foreign automakers as a sweetheart deal for U.S. automakers, especially GM and Chrysler Group LLC, which received government bailouts.

Daimler AG and Volkswagen AG, both based in Germany, didn’t sign agreements, saying the plan gave an advantage to light trucks, primarily made by U.S. automakers. Honda, which signed the agreement, made similar assertions in e-mails that Issa’s committee released earlier this month.
