If your workplace is anything like ours, it seems that while you're at work, most of the rest of the United States has taken the entire week off to celebrate Independence Day. For our own celebration, and with a friendly nod to our defeated British colleagues, we thought it would be appropriate to...

Hybrid vehicles cost more upfront than comparable gasoline models, but get better fuel economy. So will you save money in the long run? To make the comparisons easier and more accurate, the FuelEconomy.gov site has launched a new comparison tool that provides a "Years to Payback" number based on...

The New York Auto Show, now open to the public, occupies two floors of the Javits Convention Center, and organizers this year were strict about relegating trucks to the basement. Chrysler was allowed only a single truck or crossover in its entire main-floor display. So it chose the 2013 Ram 1500...

With conventional gas engines incremental improvements of the range of 20% are possible over a 20 year span, but for really large gains alternative technology seems to be necessary.

Smaller, more efficient engines will be all the rage for the next 15 years, as automakers work to meet gas-mileage standards reaching past real-world averages of 40 miles per gallon. One of the most eagerly awaited is Ford's three-cylinder, 1.0-liter EcoBoost engine, first shown at the Frankfurt...

Honda has managed to raise the gas mileage ratings on all of its new 2012 Civic models, including the 2012 Civic Hybrid, which is rated at a combined 44 mpg. In a road test over several days last May, we managed to get a real-world 45.3 mpg over a route that was about two-thirds highway, one-thirds...

Automakers have long known there's a double standard for gas mileage. Cars have to meet higher goals, trucks have less stringent requirements. And the larger the vehicle, the lower the average fuel economy it has to deliver. The proposed fuel economy standards for 2017 through 2025 vehicles...

The 2013 Dodge Dart, which will be fully revealed to the public at next week's Detroit Auto Show, achieved an unadjusted gas-mileage rating of at least 40 mpg, according to Chrysler. But hold on; before you rush over to the dealership and put money down, consider that 'unadjusted' means that it's...

Yep, it's almost the end of the year, which means reams of roundup stories from all your favorite auto websites. Nope, we're not that different: We've got one too. Here's our take on the five most important stories--or perhaps themes--of 2011 in the growing world of green cars. New fuel economy...

The advocacy group Consumer Watchdog has called for the EPA to test whether the Hyundai Elantra lives up to its EPA gas-mileage ratings in real-world use; owners have complained that it doesn't.

One of the best ways to improve fuel economy is to keep a car's engine operating at its most efficient speed, regardless of how fast the vehicle is traveling. That's the principle behind continuously variable transmissions, or CVTs, which use belts and variable pulleys to match road speed to an...

With new corporate average fuel economy rules now taking us to 54.5 mpg by 2025, gas mileage will be the focus of new-car development for years to come. With its 15 years of experience in hybrid-electric vehicles, Toyota seems well positioned for steady improvements. Now, there's a chance that...

Chevy has announced sales of the one millionth Cruze on the day that marks the automaker's 100th birthday.

Sometime next month, the EPA and NHTSA will release final draft rules that increase corporate average fuel economy standards to 54.5 mpg by 2025. Most--although not all--carmakers have signed off on the standards, but opposition has hardly died down. The latest group to take up the fight against...

It's autumn, so what better way to highlight the changing leaves than a tomato-soup red Chevy Sonic subcompact? Three weeks ago, we drove our first new Sonic: a high-end 2012 Sonic LTZ sedan with the 1.4-liter turbocharged engine. We liked the little turbo, and found the sedan roomy and comfortable...

You've gotta hand it to automakers. However tight the noose of emissions regulations and MPG targets gets, the engineers always find a way to wriggle free with ever more impressive fuel economy figures. Mitsubishi's way of meeting ever tighter targets is to update its MIVEC variable valve timing...

If you're in the market for a new car and your top priority is fuel efficiency, what do you buy? With so much to choose from now including gasoline, diesel, natural gas and electric cars on the market as well as a range-extended electric vehicle and hybrids galore, the options are bewildering. If...

The EPA's MPG equivalent (MPGe) ratings for electric cars aren't the simplest of things to understand, worked out through a series of different calculations. When an electric car gets 350 MPGe to the more well-known 2012 Nissan Leaf's 99 MPGe rating though, you know it must be something special...

Over a short test that mimicked commuter duty, our 2012 Hyundai Accent SE hatchback returned 33.4 mpg.

It was the proposal that brought every automaker selling in the North America market out in a cold sweat. Now, Reuters brings news that the NHTSA and the Environmental Protection Agency (EPA) are delaying the 54.5 MPG, 2025 average fleet fuel economy figure proposal until November. The reason given...
