Dieselgate 2.0? EPA claims Jeep and Ram also cheated on emissions

The United States Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) have accused Fiat-Chrysler Automobiles (FCA) of selling diesel-powered light trucks that pollute more than they’re legally allowed to.

A statement published on the EPA’s official website explains that 104,000 trucks and SUVs sold in the U.S. over the past couple of years don’t comply with emissions regulations. The vehicles affected include Jeep Grand Cherokees and Ram 1500 EcoDiesels for the 2014, 2015, and 2016 model years. Both trucks are fitted with a 3.0-liter V6 engine. The Cummins-supplied, 6.7-liter straight-six diesel found under the hood of Ram’s heavy duty models isn’t targeted by the EPA’s probe.

According to the agency, FCA violated the federal Clean Air Act by not disclosing engine management software that alters emissions, allowing the six-cylinder oil-burner to emit more nitrogen oxide (NOX) than it’s allowed to. Importantly, the EPA pointed out it’s still investigating whether the software can be considered a defeat device like the one found in over half a million Volkswagen TDI models. FCA’s fines will largely depend on the EPA’s findings.

“Once again, a major automaker made the business decision to skirt the rules and got caught,” said CARB Chair Mary D. Nichols. “CARB and U.S. EPA made a commitment to enhanced testing as the Volkswagen case developed, and this is a result of that collaboration.”

The automaker doesn’t agree with the EPA’s accusations, and it asserts that its 3.0-liter V6 is fully compliant with all applicable regulations. The company has spent months providing the EPA with countless documents to prove that it has nothing to hide, and it has even proposed to implement a software fix that would curb tailpipe emissions in the Grand Cherokee and the 1500.

“FCA US intends to work with the incoming administration to present its case and resolve this matter fairly and equitably, and to assure the EPA and FCA US customers that the company’s diesel-powered vehicles meet all applicable regulatory requirements,” said the company in a statement. It also stressed that the engine management software singled out by the EPA is not a defeat device.

FCA could be fined $37,500 per offending vehicle if it is found guilty of violating the Clean Air Act. The company’s shares dropped by 14 percent immediately after the EPA’s announcement.

Stay tuned, we’ll update this developing story as more information becomes available.

Rivian R2 vs Hyundai Ioniq 5: Should you wait for the Rivian R2?
Rivian R2

Rivian has taken the wraps off of the Rivian R2, an electric SUV that's similar to the much-loved R1S, but smaller and, crucially, cheaper. But the R2 goes up against some serious competition. The likes of Hyundai have been building solid EVs for some time now -- including the Hyundai Ioniq 5.

The R2 and the Ioniq 5 each make a compelling case for themselves, and they're likely to end up being similarly priced if the Ioniq 5 doesn't get much cheaper and the R2 does end up being sold at $45,000. To be fair, the cars are pretty different -- the R2 is more of an SUV, while the Ioniq 5 is much more crossover-sized. But because of their similar price, you might be deciding between the two. How do they compare? We put the Rivian R2 and the Hyundai Ioniq 5 head-to-head.
Design
The differences between the Rivian R2 and the Hyundai Ioniq 5 are perhaps no more apparent than when it comes to design.

The 6 best remote car starters in 2024
Best car remote starters

While some modern vehicles come standard with remote start features, it's still relatively uncommon. That's a shame because if you live somewhere where cold weather, snow, and ice are frequent concerns, a remote car starter is one of the best auto accessories you can have. If you're not familiar with them, a remote car starter works similarly to a key fob, except it will actually start your car from a distance instead of just unlocking the doors or trunk. That means you can start your car from the warm comfort of your home or office before venturing out. If you live somewhere hot, you can even start your car and let the AC run for a little bit. You'll never enter a freezing cold or scorching hot vehicle again.

The best remote car starters have long ranges, replaceable batteries, and other handy features — but how do you know which is best for you? We’ve compiled a list of the best car starters in a range of prices and features. Keep in mind that while you can install some yourself, some will require a professional.
