Fuel Efficiency

The market's shift to crossovers and SUVs is well documented, but what may be less well known are the massive discounts some automakers now offer on small cars as a result. While those small cars may deliver smaller profit margins, automakers must now add in steep discounts to move them from...

This month's best deals for hybrid, electric, and fuel-efficient cars are in and buyers will find a handful of eco-friendly bargains. Most cars have held their spots from October 2017, but a few newcomers may surprise shoppers, including the brand-new 2018 Toyota Camry Hybrid. Read on to see where...

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...

Diesel-powered cars have enjoyed a comfortable market share in Europe for decades, but their decline in popularity continues following numerous diesel-emission cheating scandals and regulatory crackdowns. As if diesel cars hadn't already had enough negative press, a new study says "fuel-efficient"...

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...

The 2017 Toyota Prius Prime is an automotive enigma. It proudly flaunts its eco-friendly credentials, yet its factory-rated 25 miles of electric range simply pales in comparison to the 53 miles advertised by the Chevrolet Volt. I hopped into a Titanium Glow (think beige) 2017 Prius Prime for a...

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...

Lately, automakers haven't been touting the rising fuel economy of new vehicles, but it has to continue rising to meet reductions in the legal levels of carbon emitted. While major strides in fuel economy have been made over the past five years, the complex engine technologies and other...

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...

Cadillac revealed its latest addition to the XT5 crossover range in China at the Chengdu auto show—and it has fuel efficiency in mind. General Motors' luxury division introduced the Cadillac XT5 Hybrid, which replaces two trim levels solely powered by gasoline engines. The Cadillac XT5 Hybrid...

Entrepreneur Paul Elio's concept for a simple three-wheeled car that would cost only $6,800 has now been with us for eight years.

Consumers all over the world, but especially in North America, are buying more crossover utility vehicles and fewer passenger sedans and hatchbacks. The U.S. auto industry makes the bulk of its profits on light trucks, which include crossovers, pickup trucks, and even minivans. The Trump...

Those who've lived in New York City since 2001 sometimes choose to avoid the World Trade Center site when possible. The area has largely been rebuilt into a combination of offices, shopping, and the 9/11 Memorial and Museum, with construction on some very tall towers still ongoing. A lunch date...

Automakers appear to have united behind a surprising position: reviews of emission rules should not involve scrapping the current standards. The Alliance of Automobile Manufacturers, a lobbying group that represents automakers building cars in the U.S., has suggested the Trump administration should...
