The Justice Department has opened an antitrust probe into four automakers that formed a pact with California to compromise on tailpipe emissions, effectively circumventing federal regulators, last July.

Over the summer, Ford Motor Co., Honda Motor Co., BMW AG and Volkswagen Group announced a joint agreement with the California Air Resources Board to adhere to fueling standards slightly lower than Obama-era rules but still significantly higher than the Trump administration’s proposal from 2018. The Justice Department is seeking to determine whether or not that qualifies as a violation of federal competition laws. (Read More…)

Fresh off giving Chevy a good drubbing in the American sales race, Ram has announced pricing for its new batch of EcoDiesel half-ton pickup trucks.

We’ll save you a click and tell you above the fold that the cheapest way to get into a new Ram EcoDiesel is by way of two-wheel drive Tradesman wearing Quad Cab clothes. That truck stickers for $36,890 plus destination. There’s more to it than that, of course, so you’ll want to hit the jump to learn why Ram feels the need to offer not one but two different EcoDiesels in their showrooms at the same time.

While we’ve dinged the media for erroneously reporting that automakers were unilaterally “backing” California in the fuel-economy fracas that’s currently taking place within American politics, it appears four of them actually are starting to choose a side. However, this again requires a bunch of clarification. Despite not adhering fully to the state’s ideal emissions scenario, Ford Motor Co., BMW Group, Volkswagen Group, and Honda Motor Co. released a joint announcement stating they have reached a voluntary agreement with the state of California to adopt compromised vehicle emissions rules.

Since there’s nothing binding in the joint agreement and automakers make (and break) promises all the time, the deal is largely meaningless. Doubly so, since the fuel-economy rollbacks have yet to be finalized. But this does illustrate how a handful of manufacturers are willing to accommodate others in order to get a nationwide solution. It also shows a softening of California’s previously ironclad environmental stance, which is much more interesting.  (Read More…)

Sajeev,

I recently bought a 2002 Miata, manual transmission, in silver. The prior owners appear to have been followers of the sans souci school of maintenance, so I have been wrenching on it quite a bit. It has only one problem I can’t solve: a persistent P0301 code, showing a misfire in Cylinder 1. The actual experience of driving the car is fine — I don’t feel a miss or a drop in power. That light, though… it isn’t constant. It doesn’t come on instantly; if I clear it, I might get a few minutes of light-free driving, or an hour, or a day. But after that, the CEL goes blinky-blinky.

Logic suggests that the misfire can only come from spark, air, or fuel, so I went at each as follows:

  • Spark: I’ve replaced the spark plugs (NGKs), plug wires (ditto) and boots. I swapped ignition coils to see if the code would move; it didn’t. The ignition wiring harness has some broken protective tape, but I don’t see any broken wiring.
  • Air: I’ve replaced the air filter and checked for vacuum leaks.
  • Fuel: I replaced the fuel filter, and, to make sure I didn’t have a fuel injector problem, I swapped the injectors between cylinder 1 and cylinder 4. I spilled a bunch of fuel, but the code stayed put.

I’ve been busy fixing other issues (leaking valve cover gasket, cracked radiator, soft top made of cheesecloth) on this Miata, but the P0301 has me stumped. I checked compression, and it’s good across all four cylinders. Forums mostly argue in favor of ignition problems, but I feel like I’ve covered that area.

The big question is this: Do you think new driving shoes will fix the problem?

America’s gas war is heating after 17 states, as well as the District of Columbia, filed a lawsuit against the Environmental Protection Agency’s decision to redefine U.S. vehicle emissions and fuel efficiency rules through 2025.

In April, EPA chief Scott Pruitt said the existing standards for model year 2022 to 2025 vehicles should be revised. The suit, filed in the U.S. Court of Appeals for the District of Columbia, alleges the EPA acted unpredictably, failed to follow its own regulations, and was in direct violation of the Clean Air Act. New York Attorney General Eric Schneiderman claimed the “Trump administration conducted a phony study” to justify altering emission rules to appease automakers and the oil industry.

Meanwhile, U.S. Representatives Doris Matsui of California and Paul Tonko of New York are demanding the EPA hand over all documents related to the study that resulted in the proposed changes to fuel economy standards.  (Read More…)

During the Trump administration’s year-long quest to roll back Corporate Average Fuel Economy (CAFE) targets, it attempted to give automakers in violation of the current standards a break by delaying the scheduled increase of penalties. The logic here is that the federal government is reassessing the Obama era standards, so it lumped in the new fines that were supposed to go into effect last July.

Those penalties represent an increase of $8.50 for every tenth of a mile per gallon a new car consumes above the minimum fuel standard. But with the new targets in quasi limbo, the updated fines were not being applied.

On Monday, a federal appeals court ruled the Department of Transportation cannot do that. Since the old rules are technically still in effect, the court ruled that automakers are still subject to the fine.  (Read More…)

The automotive industry wants to make 95 octane gasoline the new normal for the United States and it has taken its case to Washington. On Friday, Dan Nicholson, General Motors’ vice president of global propulsion systems, told the House Energy and Commerce Committee’s environment subcommittee that switching to 95 octane would align the U.S. with Europe and is one of the most affordable ways to boost fuel economy and lower greenhouse emissions.

Affordable for automakers, that is. Because there is no reason to think your local gas station will suddenly do you a solid and price 95 octane lower just because 87 is gone.  (Read More…)

Like something from the Nixon era, the U.S. Southeast is currently in the grips of a gasoline shortage, all thanks to the shutdown of the Houston-to-New York Colonial Pipeline. North Carolina and Virginia have declared a state of emergency as gas pumps dry up.

Even TTAC’s Bozi Tatarevic can’t find premium unleaded to save his life. His WRX’s tank runneth dry.

The sudden gas crisis provides a perfect backdrop for a study by the American Automobile Association showing that 16.5 million Americans gassed up their vehicle last year with octane they didn’t need. (Read More…)

One struggles to count on more than one finger the number of fuels debated more than ethanol — in America, corn-based ethanol specifically. Many detractors claim ethanol’s disadvantages outweigh its benefits. Proponents for ethanol in our fuel supply contend the fuel’s geopolitical positives and other factors give ethyl alcohol much needed consideration. Unfortunately, both sides of the ethanol coin have a multitude of reasons for supporting or protesting the fuel beyond the immediately obvious.

Enter Automobile’s Jamie Kitman. The man is looking to separate the corn from the husk in a new multi-part series dubbed “The War Against Ethanol.”

The complaint most often tossed at Formula 1 is that despite being the (alleged) pinnacle of motorsports, its relevancy to road cars has disappeared.

That same feeling is what brought us to the current formula of tiny 1.6-liter turbocharged six-cylinder engines, all coupled to a complex hybrid system. Since that move, the racing series has focused more on engine development that in almost any era before, and with that comes a breakthrough in the way we look at thermal efficiency.  (Read More…)

Sajeev,

Thanks for the recent advice on winter tires & wheels for my new Focus ST. I took delivery of the car two weeks ago and I’m having a blast. The first thing I did when I got it home was take Bark M’s advice and sign up for the Octane Academy.

So here’s another question: What’s your take on fuel octane and the ST?

The recent fall in fuel prices isn’t just an opportunity for Americans to demonstrate their collective inability to remember the events of even the recent past; it’s also a decisive hammerblow to E85 plants and retailers across the country.

This has to be the case, right?

The Senate of Brazil has just approved the law permitting that an additional 2.5% of anhydrous ethanol be put into what is sold as gasoline in this country. After an increase in 2013 from the previous 20% limit to 25, now cars will have to adjust to the new limit of 27.5%. Now, gasoline cars, made to run on fuels with much less ethanol content, will now have to perform with as much as 30% of ethanol in their fuel.

From Zero Hedge, a look at global gas prices, with New York City as the benchmark. A look at the price of a liter of gas (multiply by 3.8 for the gallon equivalent) gives a better picture of the choices that people make around the world when it comes to buying cars.
