Gas Mileage

With electric pickup trucks from Ford, GM, and others—including newcomers like Rivian—looking likely to arrive in the next few years, the truck field could be on the verge of a clean, quiet, tailpipe-emissions-free shakeup. That said, you wouldn’t know this segment as being poised...

Which two companies announced expanded lines of plug-in hybrids this week? What big decision did Tesla take back? This is our look back at the Week In Reverse—right here at Green Car Reports—for the week ending March 15, 2019. The big news this week was Tesla's unveiling of its...

Yesterday, when we brought you our 2019 Toyota RAV4 Hybrid first drive review, we missed one very important point. At 39 mpg, the RAV4 Hybrid is now the highest-mileage sport-utility vehicle (as the EPA lists them) without a charge port. All the more impressive is that it’s not a low...

Rather than continue to ratchet standards up to 54.5 mpg by 2025, as the current law requires, the new proposal would stall out fuel economy increases at just short of 42 mpg in 2020, and hold them there through 2026.

Though sedans might lack the high seating position of crossovers, the Camry remains proof that they’re more stable, quieter, and guzzle far less gas. They’re also cheaper.

The four choices included are: The same as set by the Obama Administration (59.4 mpg), an even higher level, the minimum 35 mpg required by Congress under the 2007 Energy Independence and Security Act, or at some lower level down to and including repealing Corporate Average Fuel Economy rules...

Over the lifetime of a car, small things can make a big difference. When it comes to fuel economy, just 1 or 2 mpg can add up to hundreds of dollars left in owners’ pockets. That may not mean much to luxury buyers, but for compact sedans that start at less than $20,000 and their owners, every...

While plug-in electric cars are steadily growing in sales, they still pale in comparison to the hundreds of thousands of compact crossover utility vehicles sold each year by virtually every major carmaker. In 2017, Toyota's most popular vehicle became the RAV4 small SUV, supplanting the Camry...

Two years ago this month, Fiat Chrysler Automobiles essentially threw in the towel on the "automobiles" part of its name. Canceling the compact Dodge Dart and the mid-size Chrysler 200 sedans, the company doubled down on the pickup trucks and utility vehicles that had long been its profit centers...

Journalism as an industry is under great pressure these days. There are far more people writing "content" than in past decades, and in general they are having to produce more of it for less money than they did 10, 20, or 50 years ago. That's no excuse, however, for getting the basics wrong. DON'T...

EPA administrator Scott Pruitt said yesterday the agency plans to modify rules limiting carbon-dioxide emissions for light-duty vehicles in model years 2022 through 2025. The agency, he said, had reached a determination that the limits put in place in 2012 under the Obama administration were...

As the auto industry and environmental groups count down the days until the NHTSA releases proposals to revise fuel-economy standards, surveys show one industry wants the standards to stay just as they are. That is the auto-parts supply industry, according to a study released Thursday morning by...

Last Tuesday, EPA administrator Scott Pruitt said the agency does not intend to let California set the agenda for national emission limits on vehicles. He suggested to Bloomberg the EPA plans to cut emission rules aggressively to respond to carmakers' pleas for easing of the corporate average fuel...

Now, it's war, in the words of California's lead emission regulator. In what Bloomberg News called a "wide-ranging interview" with EPA chief Scott Pruitt, he indicated the agency does not intend to let California set the agenda for national emission limits on vehicles. Bringing California into line...

While plug-in electric cars get lots of media attention, they remained just 1 percent of U.S. vehicle sales last year. And while the Trump Administration appears dead-set on rolling back emission limits and fuel-economy requirements established years ago, that effort will undoubtedly face lengthy...

Early in 2014, Toyota filed a voluntary recall notice with the NHTSA to fix a defect in roughly 800,000 third-generation Prius Liftback hybrids sold in the U.S. from 2010 through 2014. The company said it would make unspecified changes to software that controlled the vehicle's inverter, which...

Electric cars may be all the rage, but for now, all but a tiny fraction of the 250 million vehicles on U.S. roads burn gasoline or diesel fuel. One of the ways that new vehicles are boosting fuel efficiency is the use of what are called "start-stop" systems, which switch off the engine while the...

With the release of proposed new and lower fuel-economy rules expected from the NHTSA by March 30, many eyes have turned to the powerful California Air Resources Board. The state's pioneering role in reducing emissions and cutting air pollution predates even the existence of the U.S. Environmental...

It's been clear that under the Trump administration, the NHTSA and EPA plan to roll back linked fuel-economy rules and emission limits on new vehicles. Now a possible justification that will be used has emerged—and it's not the one many advocates had expected. According to a Bloomberg report...

The Toyota Prius hybrid has been its maker's "halo car" and an example of its most advanced technology for two decades. Launched from an early-1990s project to halve the fuel consumption of a small car, its hybrid-electric powertrain pioneered mass electrification of passenger cars. But the sales...
