16Mercedes-Benz rewarded by EPA for implementing start-stop

The last Mercedes-Benz AMG model I drove was the CLS63 AMG. It had a 5.5-liter, twin-turbocharged V8, 550 horsepower and 590 pound-feet of torque. Oh, and it also had a standard stop-start system and an Eco mode, two features that are kind of silly on a sedan that will hit 60 miles per hour in under four seconds.

AddEPA says automakers ahead of schedule for 54.5 MPG by 2025

Remember, the target is 54.5 miles per gallon by 2025. Today, the CAFE level is a little over 30. How we get from here to there is something the US Environmental Protection Agency (EPA) is monitoring closely. Thus, the EPA just released an annual flash report on how the auto industry is progressing towards meeting the nation's fuel economy goals.

92Average new-vehicle mpg ratings continue to climb, now up to 24.8

The average fuel economy of new cars sold in the US is going back up after dropping for a couple of months. The University of Michigan Transportation Research Institute (UMTRI) calculated a 24.8 mpg average for new light-duty vehicles sold in the US during November 2013. That's not as high as the 24.9 reported in August, but the numbers have been coming back up. The November rating was up 0.1 mpg from October.

10How new CAFE rules will force pickup trucks to get cleaner

The PDF rules for the just-made-official new Corporate Average Fuel Economy (CAFE) standards for model year 2017-2025 vehicles that was officially finalized at 54.5 miles per gallon recently are, as previously noted, over 1,200 pages long. We've been reading through them, and found some interesting tidbits regarding the fate of better, cleaner trucks.

55Under new CAFE rules plug-ins, natural gas, hydrogen cars are "incentive multipliers"

The new Corporate Average Fuel Economy (CAFE) standards for model year 2017-2025 vehicles was finalized at 54.5 miles per gallon today. The official rules document, though, is a whopping 1,230 pages long, and it take a while to decipher what in there. Things like the incentives for what the Environmental Protection Agency calls "game changing" advanced vehicle technologies. You can download the whole thing in PDF, but here are the pertinent points when it comes to the incentives.

189New CAFE rules officially finalized; 54.5 mpg is like making gas $1/gallon cheaper

Increasing the Corporate Average Fuel Economy standards for model year 2017-2025 cars to 54.5 miles per gallon was first proposed in July 2011. Since then, there has been a lot of back and forth, a lot of positive and negative responses, and, lately, a delay for unknown reasons. Since the CAFE rules were not changed between the mid-1980s and when President Obama came into office and rules for 2012-2016 model year vehicles were put in place in 2010, it's not a huge surprise this update took so lo

44House Republicans urge White House to delay 2017-2025 fuel economy standards

Representatives from the Republican Party have asked President Obama to delay pushing through strict new automotive fuel economy regulations. The trio of top GOP legislators consists of auto dealer Mike Kelly of Pennsylvania, Jim Jordan (also of PA) and House Oversight and Government Reform Chairman Darrell Issa of California (pictured). The three legislators are calling for further review of the 2017-2025 Corporate Average Fuel Economy targets. According to a report by The Detroit News, Issa sa

2154.5 MPG CAFE rule implemention delayed, review will be completed 'soon'

Despite the positive public face, the behind-the-scenes discussions that resulted in the 2025 CAFE standards of 54.5 miles per gallon agreement were not easy. There might be more problems going on, since the Obama administration has pushed back implementation of the new rule – which affects model-year 2017 vehicles and later – to a later date. A self-imposed deadline meant the rule was supposed to be issued yesterday.

6254.5 MPG fuel rule negotiations were not harmonious

If you assumed that the federal mandate requiring automakers to reach the 54.5 miles per gallon corporate average fuel economy standard by 2025 was negotiated cordially and ended in a group hug, think again. Verbal fisticuffs and head butting would be more accurate descriptions, with members of Congress and automakers joining the squabble with the federal regulatory agencies. During the negotiation process, foreign automakers took umbrage with more favorable treatment domestic makers seemed to b

61Consumers say they want more fuel-efficient vehicles, but do they buy?

Could this be a case of "do as we say, not as we do"?

48Stricter fuel-economy standards reduce electric-drive investment

Some may call it a variation on the low-hanging fruit theory. Others may call it a daft conclusion.

31U.S. drivers to save $68 billion in 2030 with new CAFE standards

What an extra few hundred bucks a year or so in everyone's pocket will buy almost two decades from now is anyone's guess, but for us, that's beside the point.

20Fewer flashy debuts, more serious efficiency efforts thanks to new CAFE rules

Jim Kliesch, the Clean Vehicles Program research director for the Union of Concerned Scientists (UCS), is noticing a change. Instead of hyping marquee "green" cars, auto manufacturers are settling into a groove where they regularly show off packages of conventional fuel-saving methods that will allow them to bring more-efficient vehicles to market. These small changes add up to noticeable results, he said during an interview at the New York Auto Show last week, and that's important, since fuel e

35Consumer advocates tout proposed U.S. fuel-economy standards as a cost saver

Consumer advocates said Thursday that the U.S. public is generally in favor of the stricter fuel-economy standards the federal government proposed last year for 2025 and that the average driver would typically save money in the form of lower refueling costs, even if vehicle prices rise as a result.

34Rep. Issa asks CARB for more documents about 54.5 mpg CAFE standards

A month ago, Darrell Issa (R-CA) sent letters to 15 automotive CEOs asking them for information about the possible safety effects of implementing the proposed new fuel economy standards. Now, he's following up with a new request to California Air Resources Board chairwoman Mary Nichols for documents about how CARB, the Obama administration and the automakers came to the agreement to hit 54.5 miles per gallon by 2025. He's been down this road before, and claims that the 4,000 documents CARB sent

41Medium-duty truck fuel regulations under legal fire

A legal firm representing a small group of construction companies, dump truck operators, and contractors has filed suit to block new fuel economy standards for medium-duty trucks.

44Darrell Issa asks 15 automakers if higher CAFE level might hurt sales, safety

Darrell Issa is on a mission. The House Republican from California is stepping up his quest to figure out if the new CAFE standards are part of President Obama's "Green-Energy Agenda is Killing Jobs" (Okay, technically, that's Issa's report about Solyndra, but it shows where he's coming from) or potentially affecting safety.
