EPA suspected Fiat Chrysler of using 'defeat device' in 2015

U.S. regulators told Fiat Chrysler Automobiles in November 2015 that they suspected some of the automaker's vehicles were equipped with secret software allowing them to violate emission control standards, according to emails disclosed on Friday. The U.S. Environmental Protection Agency and California Air Resources Board accused Fiat Chrysler in January of using the software, known as a "defeat device," to illegally allow excess diesel emissions in 104,000 Jeep Grand Cherokees and Dodge Ram 1500 trucks built between 2014 and 2016. Byron Bunker, director of the EPA's Transportation and Air Quality compliance division, said in a January 2016 email to Fiat Chrysler, obtained by Reuters under the Freedom of Information Act, that he was "very concerned about the unacceptably slow pace" of the automaker's efforts to explain high nitrogen oxide emissions from some of its vehicles. Nitrogen oxide is linked to smog formation and respiratory problems. Bunker's email said the EPA had told Fiat Chrysler officials at a November 2015 meeting that at least one auxiliary emissions control device on the car maker's vehicles appeared to violate the agency's regulations. Mike Dahl, head of vehicle safety and regulatory compliance for Fiat Chrysler's U.S. unit, responded in a separate email that the company was working diligently and understood the EPA's concerns. He added that if the EPA identified Fiat Chrysler vehicles as containing defeat devices it would result in "potentially significant regulatory and commercial consequences." The documents redacted the vehicles named, but two officials briefed on the matter said they referred to diesel models. The EPA's November 2015 meeting with Fiat Chrysler came two months after Volkswagen AG, mired in a major tailpipe emissions scandal, admitted to installing secret defeat device software in hundreds of thousands of U.S. diesel cars to make them appear cleaner than they were on the road.

A plea for Ram to build the Hellcat-powered Rebel TRX concept

The Rebel TRX Concept is a high-performance off-roader with a supercharged 6.2-liter Hemi V8 that's capable of traveling at speeds of up to 100 miles per hour on rough terrain. There's only one other road-legal machine that has the same off-roading capabilities as the concept – ahem, the Ford F-150 Raptor – and if there's ever been a vehicle that Ram needs to build, it's this one. The market is saturated with pickup trucks of various sizes. Ram itself offers options for consumers looking to tow massive cargo or go off-roading with the Power Wagon and Rebel. But there's also a clear market for the hardcore off-roader, and the Raptor has gone unchallenged for too long. This content is hosted by a third party.

Demand for the vehicle skyrocketed and after a few years, Ford had to up production from three to five trucks per hour at its Dearborn Truck Plant in 2013. The original V8 model immediately gained stardom for being a purpose-built machine capable of tackling rough terrain at high speeds. The latest 2017 Raptor is shaping up to be a brute in its own right. Gone is the 6.2-liter V8, which has been replaced with a modern twin-turbocharged 3.5-liter V6. Despite having a much smaller engine than its predecessor, the upcoming Raptor boasts better performance at 450 horsepower and 510 pound feet of torque – up from the V8's output of 411 horsepower and 434 pound feet of torque. With Fox lending a hand with some high-performance shocks and the pickup truck getting various off-roading modes, including one called "Baja," few road-legal machines will be able to match 2017 Raptor when asphalt runs out. Even still, the Rebel TRX concept looks and sounds like it's in a different league. The Rebel TRX concept's design is the perfect combination of speed and looks, which makes it hard to believe that Ram built the concept in just three months, according to an engineer. A higher-up within FCA sent in the demand, and the Ram team obliged with a fully functioning prototype. The Rebel, which Ram has always said is not a Raptor-fighter, can be fitted with the 5.7-liter Hemi V8, while the larger Power Wagon is equipped with the 6.4-liter V8. The supercharged 6.2-liter V8 (the Hellcat engine), as an engineer points out, makes sense in the concept.

Auto journo learns hard way that new vehicles burn differently than old ones

Terry Box, a writer for the Dallas Morning News, was tootling down the Dallas North Tollway in a Ram 1500 Laramie Longhorn pickup after work and enjoying the ride. Box thought the $53,335, option-filled press loaner had been "flawless - very serious competition for anything built by Ford or Chevy." And then, for reasons that still aren't clear, something in the engine compartment caught fire and the Ram cremated itself on the shoulder of an off-ramp.
Box tells the story and it isn't an indictment of the truck, but a cautionary tale about how new vehicles don't burn like the old ones did - and why not to go back for your gym bag. It could also be a kind reminder about what kind of safety gear everyone should keep in their cars. Click the link to read the whole piece.
