Staff at the Environmental Protection Agency had major disagreements over the decision to rollback corporate average fuel economy (CAFE) standards for the coming years, according to documents released last week. The matter echoes an event in May where science advisers for the EPA claimed the agency had ignored its own research in order to rationalize the push to relax fuel targets.

Both items have given ammunition to critics of the new proposal to claim the choice was politically motivated and based upon shoddy, biased research. Interesting, considering that’s exactly what the current administration said about the earlier decision to make them more stringent.

Led by the National Highway Traffic Safety Administration and backed by EPA, the current proposal seeks to keep fuel economy standards at 2020 levels — rather than continuing to elevate them. The arguments made for the move revolved around existing consumer preferences and saving lives. However, some of the agency’s staff seemed to be concerned with the NHTSA’s data and claimed it had overstepped by including the EPA in documents it didn’t approve of.  (Read More…)

The diesel version of Mazda’s wildly popular CX-5 crossover was originally supposed to land on these shores in late 2017, but the plan hit a snag. As such, we’re still waiting. But the model’s appearance now seems imminent.

Having cleared the Environmental Protection Agency’s stringent testing regimen, we now know exactly what fuel economy to expect from the CX-5 and its compression ignition 2.2-liter Skyactiv-D inline-four. The question is: is the CX-5 diesel thrifty enough? (Read More…)

The EPA’s getting quite a few mentions on TTAC today, but it’s not because of the agency’s planned rollback of corporate average fuel economy standards. No, it’s because of odd fuel economy rollbacks seen among 2019 Chevrolet models.

We told you earlier about the yet-unexplained drop in city and combined fuel economy for the 2019 Chevrolet Colorado and GMC Canyon diesels. Now you can add the 2019 Chevrolet Camaro to the list of models with missing MPGs. It seems that in one area of performance, 10 speeds isn’t better. (Read More…)

Until an automaker comes along with something better, your cheapest bet for highway fuel economy in a pickup is the Duramax diesel-powered Chevrolet Colorado and its GMC Canyon twin. The full-size Ford F-150 with 3.0-liter diesel V6 matches it in economy, but not price.

Boasting a 30 mpg EPA rating for highway consumption, the oil-burning midsizers command a premium over their lesser siblings, but make up for it with thriftiness and heaps of torque. The 2.8-liter inline-four generates 369 lb-ft of twist — far more grunt than the 275 lb-ft on offer from GM’s 3.6-liter V6.

However, there’s a mystery afoot. The EPA ratings for the newest Colorado and Canyon diesels show a drop in city and combined efficiency for the 2019 model year, despite the powertrains being a carry-over. (Read More…)

One of my biggest pet peeves is the very existence of stop-start systems in modern vehicles. In theory, they’re intended to improve fuel economy by shutting down the engine while the car is stationary — when you’re effectively getting zero miles per gallon. In practice, they’re more of a nuisance than anything else. Every time I’m in a car that’s unfamiliar to me and the system shuts down the engine at a stop light, there is a fraction of a second where I assume something has gone terribly wrong and my stomach drops out of my body and onto the seat. Maybe I’ve just driven too many junkers but the sensation is always unsettling to a point where I have to deactivate the system to maintain peace of mind.

I am also fairly confident that repeatedly cycling your engine in stop-and-go traffic isn’t great for the crankshaft and a host of other components, even if the manufacturer is trying its utmost to mitigate the issue. But I’m aware that some people don’t mind their vehicle becoming a jittery, broken-feeling mess in an urban environment so long as it saves them some fuel in the long run. Unfortunately, that information hasn’t made me hate it any less.

What about you? Is stop-start technology the bane of your driving existence or a necessary evil in the war on emissions?  (Read More…)

After months of discussion, circulating drafts, and arguing with the State of California, the Environmental Protection Agency and National Highway Traffic Safety Administration formally unveiled their plan to rewrite the existing corporate average fuel economy (CAFE) rules and replace them with something far less stringent.

The proposal would freeze the presiding standards in 2020 under the “Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule for Model Years 2021-2026 Passenger Cars and Light Trucks” plan, which is a mouthful.

It also moves to revoke California’s authority to set its own mandates, as predicted. The Golden State made it clear that it wants to maintain the Obama-era limits. However, the proposal includes a section emphasizing the importance of a single national standard, saying it would seek to withdraw the waiver granted to California in 2013.

“Attempting to solve climate change, even in part, through the Section 209 waiver provision is fundamentally different from that section’s original purpose of addressing smog-related air quality problems,” reads the proposal. “When California was merely trying to solve its air quality issues, there was a relatively-straightforward technology solution to the problems, implementation of which did not affect how consumers lived and drove.” (Read More…)

Andrew Wheeler, the acting head of the Environmental Protection Agency, said the United States needs a single standard for fuel efficiency for cars and trucks on Tuesday. It’s a sentiment shared by Mary Nichols, head of California Air Resources Board, but it’s likely to put the two at odds. Wheeler said the pair shared that singular goal based off a meeting held last week, but California isn’t seeking the same benchmarks as the current administration.

The state objects to the EPA’s plan to weaken Obama-era efficiency targets, and is currently in the midst of a political and legal battle with the agency. However, Wheeler confirmed that, under his watch, the group would continue seeking a “50-state solution.”  (Read More…)

Following Andrew Wheeler’s appointment as acting head of the Environmental Protection Agency, he extended an invitation to the California Air Resources Board to discuss emission regulations — a matter which former EPA administrator Scott Pruitt seemed less inclined to discuss with the state.

Mary Nichols, chairman of the board, said Wheeler reached out to state officials and the pair agreed to hold a meeting in Washington. It’s a slight easing of tensions in the cold war between D.C. and Sacramento. (Read More…)

After Volkswagen’s diesel emissions scandal came under public scrutiny, numerous industry analysts prophesied it would not be an isolated incident. Cheating had been done in the past, and would likely continue into the future. In fact, numerous experts claimed every major automotive manufacturer probably engaged in illicit behavior to some degree. With so many laws and employees who may be interested in shirking them, it’s bound to happen time and time again.

On Monday, Nissan Motor Co. admitted it improperly measured exhaust emissions and fuel economy for 19 vehicle models sold in Japan. Late last year, Nissan and Subaru both confessed that they had allowed uncertified technicians to conduct finial vehicle inspections. Initially, the issue seemed like a harmless oversight, but in some cases the failing went unnoticed for decades, resulting in falsified data as a way to cut corners. Both Mitsubishi Motors and Suzuki admitted in 2016 that they exaggerated the fuel economy of their vehicles by cheating on tests.  (Read More…)

Environmental Protection Agency Administrator Scott Pruitt, who spearheaded the Trump administration’s initiative to roll back Obama-era fuel economy standards for light vehicles, has resigned. Even after assuming the position, Pruitt remained a tough sell as head of the EPA. His stance on climate change was uncharacteristic of any modern-day environmentalist and he seemed utterly bent on corporate deregulation to bolster profits and stimulate the economy.

Then came a flurry of scandals stemming from frivolous spending habits, improper use of authority, and possible business ties that would inhibit his ability to act in an unbiased manner. Numerous federal investigations were launched into these matters.

While a number of the impropriety claims came from political opponents actively hunting for gaps in his armor, let’s face it, Pruitt hasn’t been making things particularly difficult for them.  (Read More…)

Full-size truck buyers looking for the latest thing are spoiled for choice this year. Besides an all-new Ram 1500 (currently unavailable with a V6) and the usual offerings from Ford, there’s a next-generation Chevrolet Silverado and GMC Sierra arriving this fall.

Unlike those other models, the GM twins went somewhere full-size truck builders fear to tread: the land of four-cylinders. Looking at GM’s newly released price list for the 2019 Silverado, it’s clear the new 2.7-liter turbocharged inline-four stands to save buyers money in more ways than one. (Read More…)

The builder of the world’s best-selling vehicle, which just happens to be a large truck, finds itself in the crosshairs of yet another environmental ad campaign. Like past campaigns against the automaker, the coalition of four leading environmental groups claim Ford’s commitment to the environment pales in comparison to its thirst for profits.

Oh, and Ford Motor Company might as well change the name on its logo to “Trump.”

That’s what readers of The Detroit News and Detroit Free Press read on Saturday morning, after the Sierra Club (which is not a British Ford fan group, to be clear), Greenpeace, Safe Climate Campaign, and Public Citizen ran giant ads in both newspapers slamming the automaker for backing the Trump administration’s planned rollback of fuel economy standards.

Whoa, whoa, whoa, take it easy, Ford responded. (Read More…)

Despite the growing animosity, both California and the Trump administration are still willing to discuss the country’s changing emission regulations. The state is currently heading a lawsuit against the Environmental Protection Agency, claiming it “acted arbitrarily and capriciously” in overturning the previous administration’s decision to maintain Corporate Average Fuel Economy standards.

While the proposals issued by the current administration will eventually see those targets rolled back, a final decision has not been made. The White House claims it wants to maintain an open dialogue with the Golden State, hoping to reach an agreeable solution, but the California Air Resources Board has argued it doesn’t seem to be acting on those assertions. Meanwhile, EPA head Scott Pruitt maintains that the state will not dictate federal fueling rules as automakers beg the government to do everything in its power to ensure a singular national mandate.

It’s an ugly situation, which makes news of a new round of meetings all the more surprising.  (Read More…)

Whether the buying public likes it or not, there’s a tsunami of electrified powertrains headed for U.S. shores. Automakers the world over hope to beat their rivals in the race to a “fully electrified” lineup, which just means there’ll be — at a minimum — a hybrid variant in each model line.

It’s far less sexy than headlines make it sound. Still, if you’re into technology and saving money at the pumps (not necessarily at the dealer), it’s hot stuff. Nissan’s taking an unconventional route in this race, forgoing a conventional hybrid setup for an inexpensive stopgap solution all its own.

The system, called e-Power, is already a hit in Japan. But before it makes its way into high-end Nissan products (read: Infiniti), it first needs to upsize the system for American-sized vehicles travelling at American-sized speeds. That’s not as easy as it sounds. (Read More…)

The Trump administration has enacted phase two of its plan to revise Obama-era rules designed to cut pollution from vehicle emissions. In a proposal sent to the White House Office of Management and Budget on Thursday, the Environmental Protection Agency announced its intention to rescind the California waiver that separates it from the federal standards the state uses to regulate greenhouse gas emissions from automobiles.

Since allowing California to set its own emission standards would effective split the country’s auto market, the EPA has been clear that its ideal solution would be to cut a deal with the Golden State. Agency head Scott Pruitt previously said California “shouldn’t and can’t dictate [fueling regulations] to the rest of the country,” but acted in a manner that suggested a compromised could be reached.

This was followed by a lawsuit filed by 17 U.S. states, along with the California governor’s office, California attorney general, and the California Air Resources Board (CARB), alleging that the EPA had “acted arbitrarily and capriciously” in its decision to roll back the previous administration’s decision. While the odds are good that the Trump administration wasn’t ever interested in bending to California’s more stringent pollution policies, this was likely the point of no return — squashing any hope for meaningful negotiations.
