Gas Mileage

  • 2019 Volkswagen Jetta

    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 dime, dollar, and drop saved counts. Our colleagues over at The Car Connection finished up their first drive review and reported that the compact sedan they tested returned 37 mpg in combined fuel economy, above the 34 mpg rating from the EPA calculators. That’s good among compact sedans with...

    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

    The automakers claimed that the standards were unrealistic given that consumers are flocking to crossovers and pickup trucks as gas prices remain low. According to a new report by the American Council for an Energy Efficient economy, and to our own analysis, trucks aren't the reason.

    8 things you should know about EPA plan to let cars emit more (cutting fuel economy as well)

    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.

    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 Calstart, the national clean-transport industry association. The group commissioned Ricardo Energy & Environment to survey so-called Tier 1 suppliers on their views of the current greenhouse-gas emission standards for 2022 through 2025, the Trump administration's proposals to reduce them, and...

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

    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.

    Toyota Prius recall in 2014 failed to fix problem, lawsuit says, may have cut mileage

    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...

  • 2013 Ram 1500  -  engine start-stop system

    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 car is stopped. Now, as the Department of Energy pointed out Sunday in its Fact of the Week, the number of those systems nearly doubled last year on light trucks sold in the U.S. DON'T MISS: Don't start-stop systems wear out your car's starter? They were fitted to 10.4 percent of the light trucks sold...

    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.

    As automakers await the National Highway Traffic Safety Administration's new fuel-economy rules for 2022 through 2025, due March 30, regulators from California and Washington are still hammering out the specifics. A meeting between state and federal regulators on fuel-economy and emissions targets took place on Monday as both sides attempt to avoid a prolonged and costly legal battle that could put the final regulations into limbo for months or years. The current targets see automakers aiming for an average EPA window-sticker rating of roughly 38 mpg across all vehicles by 2025, but the Trump...
