Automakers want to stop the EPA's fuel economy rules change, and why that's a shortsighted move

With a Trump Administration looming, the EPA moved quickly after the election to propose finalizing future fuel economy rules last week. The auto industry doesn't like that (surprise), and has started making moves to stop the EPA. Ford CEO Mark Fields said he wanted to lobby Trump to lower the standards, and now the Auto Alliance, a manufacturer group, is saying it will join the fight against cleaner cars. The Alliance represents 12 automakers: BMW, Fiat Chrysler, Ford, GM, Jaguar Land Rover, Mazda, Mercedes-Benz, Mitsubishi, Porsche, Toyota, VW, and Volvo. Gloria Bergquist, a spokesperson for the Alliance, told Automotive News that the "EPA's sudden and controversial move to propose auto regulations eight months early - even after Congress warned agencies about taking such steps while political appointees were packing their bags - calls out for congressional action to pause this rulemaking until a thoughtful policy review can occur." The EPA was going to consider public comments through April 2017, but then said it would move the deadline to the end of December. That means that it can finalize the rules before President Obama leaves office. The director of public affairs for the Consumer Federation of America, Jack Gillis, said on a conference call with reporters last week when the EPA originally announced its decision that it is unlikely that President Trump will be able to roll back these changes. Gillis also said on the same call that any attempt by the automakers to prevent these changes would be history repeating itself. "These are the same companies that fought airbags, and now promoting the fact that every car has multiple airbags," he said. "These are the same companies that fought the crash-test program, and now are promoting the crash-test ratings published by the government. So, it's clear that they're misperceiving the needs of the American consumer." There are more reasons the Allliance's pushback is flawed. Carol Lee Rawn, the transportation program director for Ceres, said on that call that the automotive industry is a global one, and many automakers are moving to global platforms to help them meet strict fuel economy rules around the world.

Best places to get your car maintained and repaired

In this era of rampant inflation and high interest rates, the challenges of acquiring a car or SUV have been well documented. And so it has never been more important to protect that expensive investment by maintaining it. In recent months, Autoblog has shared Consumer Reports' evaluation of the least and most expensive car brands to keep running, as well as tips to prolong a car’s useful life. Especially since the pandemic, a number of factors have impacted these costs: more complex vehicles, new materials and manufacturing methods, a shortage of qualified technicians and replacement parts. Since 2022, repairs costs have jumped each year by about 10 percent. This month, Consumer Reports is offering a useful primer on keeping your ride in great shape, suggesting what might be the best options for searching out a repair shop, depending, as CR says, “on your car and your situation.” Author Ben Preston identifies three basic types of repair facilities: dealership service departments, independently owned repair shops, and chain repair shops. Building up trust with a specific shop and feeling comfortable going there is important. Preston quotes John Ibbotson, chief mechanic at Consumer ReportsÂ’ Auto Test Center: "You might be able to save a few bucks by going to whichever shop offers the cheapest prices, but if you want consistent, reliable service, itÂ’s best to find a repair shop you trust and stick with it,” Ibbotson says. The story goes on to evaluate each type of service facility. HereÂ’s a breakdown of CRÂ’s findings: Dealerships These work well for owners of newer cars, especially for covered warranty work. But the disadvantage is the high labor rates common to dealer service. Satisfaction ratings for dealer service departments range from very good (Acura, Lexus, Mazda, and Volvo) to not-so-good (Jeep and Kia). Dealers are best for: Fixing infotainment system glitches: "If the screen in the center of your dash has a habit of freezing up, or the touchscreen-activated climate controls arenÂ’t working, the dealership is the most likely place to find someone with the know-how to fix problems that maybe only a factory-authorized technician can access," Ibbotson says. Safety system recalibration: "Anything from a crack in your windshield to a minor fender dent can upset the calibration of the sensors that make features like automatic emergency braking and adaptive cruise control work," says Ibbotson.

How Mazda got Skyactiv-X to work is incredible

"Take everything you know about engines and turn it around," Mazda North America Vehicle Development Engineer Dave Coleman says, patiently and with a look of benevolent pity, as he's quizzed about the particulars of the company's new engine. The Skyactiv-X engine is enigmatic — and deceptively simple in operation. And the bottom line for American consumers is that they'll be able to buy a car (or crossover; we don't know yet what vehicle will first get it) by late 2019 that provides diesel-like fuel economy but runs on regular old gasoline. In between diesel and spark ignition, but it's neither To truly understand it, you have to dive into the contradictions. Take that regular old gasoline: Contrary to common sense, the lower the octane, the better it works. In the lab, the Skyactiv-X engine loves 80 octane. The lowest Americans get is 87, so the engine is tuned for that octane. Go higher and you lose some low-end torque. Coleman was right. It's hard to wrap your head around an engine that thrives just at the point when most gas engines would aggressively self-destruct. It uses a supercharger to pump additional air — but not additional fuel. It uses spark plugs to start a combustion cycle that normally doesn't need a spark. And, quixotically, it's not displacing Mazda's own American-market diesel engine, currently languishing in a seemingly endless hell of regulatory approval. More bizarre: Mazda is a tiny automaker facing real existential headwinds, and gasoline compression ignition is a massive challenge. GM and Hyundai announced compression ignition, or HCCI, projects (full name, homogeneous charge compression ignition) to great fanfare, but they never amounted to a production hill of beans, crippled by reliability issues or horrible vibrations. Worse, they only worked at an unusably narrow range — low RPMs and low loads. HCCI research improved direct-injection gas and diesel engine technologies for these companies, but HCCI itself remains untamed. The benefits of lean combustion Why even try to tame HCCI? The answer is much better fuel economy and lower emissions. Less burned carbon-based fuel, less carbon dioxide released. That's simple. But there are some thermodynamic reasons for the lean combustion you can achieve with compression ignition that are worth explaining. The ideal amount of fuel for a conventional engine to burn is about a 14:1 air-to-fuel ratio. That lets every molecule burn nicely, in theory.
