Ram 1500 Rebel TRX reveals hood scoop-mounted marker lights

Now that the Ram 1500 Rebel TRX is testing with production bodywork, the company has been doing a thorough job of covering up the off-road super truck. But fortunately lights still show through the thick coverings, and we're finally able to see the truck's wide vehicle-denoting marker lights. As you can plainly see, they're mounted to the inside of the hood scoop. This differs from the original Ram TRX concept that had its lights mounted on the roof like a traditional heavy duty pickup truck. It also differs from the Ford F-150 Raptor's grille-mounted marker lights. Both the Raptor and the TRX have these lights not just for style, but because they're wide enough to require the amber marker lights with three in the middle and one on either side of the truck. We can't quite spot the outside marker lights for the Ram. They could be integrated into the headlights, since it seems like the turn signal is particularly wide on this truck compared with regular models. The position of these lights also matches a recent report, lending some more credibility to other claims in it. We expect the Ram 1500 Rebel TRX to be revealed by the end of the year, perhaps as soon as the Detroit Auto Show, which is still scheduled for June. We know it will have a supercharged V8, since we've heard it ourselves, and reports say it will make at least 707 horsepower like the Charger and Challenger Hellcat. It has thoroughly modified suspension for high-speed off-roading, just like the Raptor. And of course it will have four-wheel drive.  

Feds sue Fiat Chrysler, accuse it of cheating on diesel emissions

WASHINGTON - The US government has filed a civil lawsuit accusing Fiat Chrysler Automobiles NV of using software to bypass emission controls in diesel vehicles. The Justice Department suit, filed in US district court in Detroit, is a procedural step that may ramp up pressure on Fiat Chrysler. The suit could ultimately help lead to a settlement, as in an earlier probe of rival Volkswagen AG that will cost VW up to $25 billion, but which affected a much larger number of vehicles. VW admitted to intentionally cheating while Fiat Chrysler denies wrongdoing. It did not immediately comment on Tuesday. US-listed Fiat Chrysler shares were down 2.9 percent at $10.44. The suit also names Fiat Chrysler's unit V.M. Motori SpA, which designed the engine in question. Reuters reported last week the Justice Department and EPA have obtained internal emails and other documents written in Italian that look at engine development and emissions issues that raise significant questions. The investigation has scrutinized VM Motori. FCA acquired a 50 percent stake in VM Motori in 2010 and the remainder in October 2013. The lawsuit asserts the Italian-American automaker placed undeclared "defeat devices," or auxiliary emissions controls, in 2014-2016 Fiat Chrysler diesel vehicles that led to "much higher" than allowable levels of nitrogen oxide, or NOx pollution, which is linked to smog formation and respiratory problems. The suit seeks injunctive relief and unspecified civil penalties. EPA said in January the maximum fine is about $4.6 billion. In January, EPA and California accused Fiat Chrysler of illegally using undisclosed software to allow excess diesel emissions in 104,000 U.S. 2014-2016 Jeep Grand Cherokees and Dodge Ram 1500 trucks. Fiat Chrysler said on Friday it plans to update software that it expects will resolve the concerns of U.S. regulators about excess emissions in those vehicles. The January notice was the result of regulators' investigation of rival Volkswagen, which prompted the government to review emissions from all other passenger diesel vehicles. Volkswagen admitted in September 2015 to installing secret software allowing its cars to emit up to 40 times legal pollution levels. In total, VW has agreed to spend up to $25 billion in the United States to address claims from owners, environmental regulators, states and dealers and offered to buy back about 500,000 polluting US vehicles.

2020 Ram 1500 4x4 Suspension Deep Dive

What is taking everyone so long? That’s what I continually ask myself each time yet another all-new full-size pickup comes out with leaf spring rear suspension. Meanwhile, this 2020 Ram 1500 pickup represents a dozen years since coil spring rear suspension debuted when its prior generation was still being called a Dodge Ram 1500. Ford, Chevrolet, Toyota and Nissan introduced full redesigns of their pickups well after Ram proved that coil springs were the way to go, and yet leaf springs persist with the competition. IÂ’m not just popping off, here. In the 1990s I used to specialize in pickup truck suspension tuning for the Toyota Technical Center. Leaf springs are crude and loaded with compromises, but thatÂ’s all that truck design engineers ever gave us to work with. I was instantly all-in on RamÂ’s move to rear coils after the first few miles of driving a 2009 Ram 1500 pickup. Empty-bed ride comfort and handling were on another level, but it could still tow and haul. In fact, towing stability proved to be frankly incredible on the normally-treacherous downhill leg of my winding tow test grade. I fully expected everyone would copy it immediately. But they didnÂ’t. Others may have doubted the payload aspects. Ram never did. It soon doubled down and put coils under the back of its 2014 2500-series trucks. IÂ’ve developed other theories that seek to explain why no one followed their lead, but theyÂ’re not worth dredging up because I think the dominoes will soon begin to fall. Spy photos suggest that the next Toyota Tundra will switch to coils, and there are rumors that the Ford Raptor is going that way. ThatÂ’s not much of a stretch because the Ranger Raptor (only available outside the U.S.) already has coil spring rear suspension. WhatÂ’s the big deal? LetÂ’s take a look at the underside of a 2020 Ram 1500 Laramie 4x4, the second iteration of the Ram 1500 to employ coil spring rear suspension.   As it has for some time, the front end of the Ram 1500 rides on double wishbone suspension. The truck employs a high-mount upper wishbone (yellow arrow) that positions the upper ball joint up behind the tire sidewall instead of inside the wheelÂ’s barrel. This layout offers improved steering geometry and reduced stress in the upper ball joint, the upper control arm and its mounting points.   Coil-over spring/shock assemblies (green) come standard on all 2019+ (fifth-generation) Ram 1500 pickups whether they have four-wheel drive or not.
