  • 2018 GMC Sierra 1500

    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 on a revolution. Progress in the efficiency and fuel economy of full-size trucks the past few years hasn’t come so rapidly, and it’s fair to sum it up as a series of small steps, canceled strategies, and sometimes contradictory moves. The Two-Mode Hybrid system, for instance, that was...

    2020 Tesla Model Y, Mazda rotary, wider VW electric plans: The Week in Reverse

    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...

    2019 Toyota RAV4 Hybrid: At 39 mpg, the highest-mileage SUV without a charge port

    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...

    Draft EPA memo freezes fuel economy standards at 42 mpg through 2026

    After announcing its intention last month to roll back emissions standards that require cars to get higher fuel economy, the EPA is now circulating a proposal in Washington to freeze the standards at 2020 levels through 2026. The story was first reported by the Los Angeles Times, and confirmed by...

    2018 Toyota Camry XLE Hybrid road-trip review: a case for high-mpg sedans

    The grim reaper might be coming for sedans, but the 2018 Toyota Camry isn’t ready to go. Today’s Toyota Camry suffers from multiple personality disorder, which, I discovered after 800 miles behind the wheel, might also be its biggest asset. Dressed up in Camry XSE trim, it wants to be a...

    2018 Lexus LC 500h gas mileage review

    As the industry marches toward greener cars, battery and hybrid drivetrains are expanding into vehicle segments never before concerned with fuel economy ratings or much with emissions. No segment is excluded from this progress, not even luxury grand tourers. Toyota, along with its luxury division...

  • Gas pump

    In light of the EPA Administrator Scott Priutt reversing the Agency's decision to maintain tighter emissions standards from 2022 to 2025, it seemed time to ask for our audience's opinion. Since 2009, the EPA emissions standards have had a direct effect on fuel economy standards and have been coordinated with the National Highway Traffic Safety Administration—which administers the standards—as well as with the California Air Resources Board, which administers separate, but also coordinated, pollution standards in the state. The standards became coordinated—"harmonized," in...

  • 2019 Volkswagen Jetta
    Is the 2019 Volkswagen Jetta the most fuel-efficient small car?

    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...

    2019 Jeep Cherokee gas mileage review

    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...

    More sedan, smaller, entry models bite the dust in Detroit

    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...

    EPA does not set fuel-economy limits: get this right, journalists!

    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...

    Why trucks aren't a CAFE problem for carmakers, despite their lobbying claims

    In response to automaker lobbying, the EPA plans to start the process of rolling back emission standards passed under the Obama Administration. Automakers claimed the associated fuel-economy rules were unrealistic given that consumers are flocking to crossover utilities and pickup trucks as gas...

  • Chrome exhaust pipe

    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 “not appropriate and should be revised." The standards it had set—agreed to in 2012 by virtually every automaker, the EPA and NHTSA, and the powerful California Air Resources Board—were "too high," he said.

    Auto parts suppliers support current fuel-economy rules, overwhelmingly: survey

    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...

    CA attorney general: we will fight looser fuel-economy, emission rules

    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...

    Pruitt won't let California set emission standards; EPA not looking at post-2025 rules

    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...

    How 2019 Volkswagen Jetta inched up its EPA fuel-economy ratings

    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...

    Lexus lowers hybrid prices to reduce premium over gasoline substantially

    Gas is cheap in the U.S. and has been for years. Hybrids are no longer a cutting-edge or cool technology; they're just another powertrain. The result is that hybrids have been quietly ebbing as a proportion of total vehicle sales. DON'T MISS: 2018 Lexus RX 450hL hybrid three-row SUV priced from...

  • 2010 Toyota Prius

    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 varies the voltage in the vehicle's hybrid system. Those changes were intended to eliminate possible overheating in the inverter when high power was transferred among the 1.3-kilowatt-hour nickel-metal-hydride battery pack and the two electric motors.

    Start-stop systems on U.S. light trucks doubled to one in five in a single year

    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.

    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.
