Even as vehicles become more fuel-efficient, the unending market shift toward crossover utilities, SUVs, and trucks kept the overall average U.S. new fleet efficiency stagnant for the fourth year in a row. For 2017, sales-weighted new-car fuel economy landed at 25.2 mpg, an improvement over 2016 of...

As Americans collectively sigh at their credit-card bills from the holiday season, GasBuddy has some bad news that won't help ease the financial pain. The fuel price-tracking website predicts the cost of a gallon of fuel will rise by $0.19 per gallon in 2018, on average, to the highest level gas...

As automakers yet again lobby Washington to roll back planned fuel-economy targets for 2025, they've employed some familiar tactics to drive the point home to lawmakers. It cannot be done. It will cost too much. It will destroy the industry and kill jobs. Consumers do not want this. The science is...

China has taken a major step toward cleaning up the new cars sold in the country beginning January 1. As numerous countries debate plans to end sales of fossil-fuel vehicles completely at points in the future, China has now forced the end of production for some 553 models, starting Monday. The...

The way a driver operates a car can produce very different fuel-economy numbers, and when driving downhill, two notable techniques come into play. The first is leaving the car in gear and using so-called engine braking to provide at least some deceleration. But many believe putting a car in neutral...

Toyota can’t be blamed for a lack of effort: The 2018 Toyota Camry Hybrid is dripping with it. From the creased hood and cascading brow to the Modernist center console enclosed by flickers of chrome, the mid-size stalwart is anything but lazy. Our first, limited exposure to the hybrid sedan...

Hyundai decided to skip the major auto-show circuit and debut its redesigned Accent subcompact sedan at a relatively minor auto show.

With the election of Donald Trump as U.S. president last November, it became clear that the regulatory environment for businesses would change once he took office. Indeed, dozens of regulations limiting corporate activities involving emissions, fossil-fuel exploration, hiring and firing, and a host...

Continuing political turmoil and news coverage of the Trump Administration haven't stopped the president's agency heads from drastically reshaping policies on energy, the environment, and emissions. Comments are now being taken on the reopened EPA limits on vehicular carbon emissions for 2022...

Even the automaker lobbying group didn't go this far in their complaints about emission and fuel-economy rules for vehicles in the 2022 through 2025 model years. When the Obama Administration approved final EPA emission rules for those years, the automakers complained that the comment period had...

The internal combustion engine, now more than 200 years old, will be with us for a long time to come yet. Powering more than 1 billion vehicles on the planet and almost 100 million new ones each year, it is the default way to move vehicles along the world's roads. With its carbon emissions now...

Fuel-economy ratings for cars sold in Europe have long been wildly unrealistic, sometimes more than 30 percent more optimistic than real-world consumption figures. Today, that will change. As of September 1, two new and more stringent testing regimes are to be used for certifying new vehicles going...

We spent a few days with a gasoline-powered 2018 Chevy Equinox back in May, but now we've driven a much rarer version.

It's a technology that's been a sort of Holy Grail in the auto industry for at least a couple of decades. Now Mazda, one of the smallest global automakers, plans to introduce it in a radical new engine to be used in a future Mazda vehicle in 2019. It's called homogeneous charge compression...

The U.S. Department of Transportation said yesterday the NHTSA is preparing to revise corporate average fuel economy requirements for model years 2022 through 2025. The proposed version of those regulations, which was issued by the Obama Administration in 2012, included steady increases for each of...

Not so many years ago, a 1.2-liter engine would only have been found in the U.S. in the smallest and least impressive of subcompact cars. It might have been a 3-cylinder, and certainly wouldn't have had even 100 horsepower. But times change, and engines of that size will soon be found even in the...

Every now and then, resourceful journalists dredge up automotive news before it emerges in a sanitized press release from the maker in question. So it is with the pricing on the 2018 Chevrolet Equinox Diesel, one of two diesel-powered compact crossover utility vehicles expected to hit the U.S...
