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.

FCA and Cummins named in diesel emissions class-action lawsuit

Chrysler is now the first United States-based carmaker to be sued for allegedly skewing emissions results. In a move that sounds eerily similar to the troubles of European manufacturers, Chrysler is claimed to have hid diesel engine characteristics causing emissions as much as 14 times higher than permitted by regulations. According to Bloomberg, the lawsuit alleges that Chrysler, together with its diesel engine partner Cummins, has concealed the nitrogen oxide output of certain Ram vehicles produced between 2007 and 2012. The NOx pollutants were meant to be broken down in a process called regeneration in the truck's NAC system, or NOx Absorption Catalyst, which predated the 2013-introduced SCR, or Selective Catalytic Reduction system. By design, the NAC captures and stores NOx emissions, converting them to nitrogen and oxygen through a catalytic process. The lawsuit claims the Cummins engine's system has a limited capacity to store the emissions, and as a result the pollutants escape, increasing emissions, worsening fuel consumption and wearing down the catalytic converter. The later, cleaner SCR system uses a urea-water injection, and it gradually replaced the NAC on Cummins 6.7-liter engines, as it was first implemented in 2011 and made standard in 2013. As Bloomberg notes, the model years of Ram trucks involved in the lawsuit predate the earliest Volkswagen "Dieselgate" models by two years. The lawsuit, filed on behalf of 500,000 truck owners, accuses Chrysler and Cummins of fraud, false advertising and racketeering. As an underlying motive, the filing mentions a 2001 change in EPA emissions standards. Announced to become effective in 2010, the EPA requirements drove Chrysler and Cummins to try and reach those already by 2007. However, the NAC system is said to have fallen short of these goals, and the filing claims that Chrysler and Cummins chose to "rig" the engines instead. The affected vehicles predate the 2014 merger of Chrysler and Fiat. FCA US has released a statement regarding the lawsuit, saying it will contest the lawsuit "vigorously".

The biggest gas-guzzlers of 2024: 'The Meanest List' is the opposite of greenest cars

In some circles — especially some automotive circles — bigger is better. This explains the Hummer, for example. In its so-called “Meanest List” of a dozen models, the American Council for an Energy-Efficient Economy (ACEEE) makes no apologies for berating “the worst-performing mass market automobiles” sold in 2024 in the U.S. The most diminutive car on the list is a Chevy Corvette Z06. At the top of this particular heap is the Mercedes-Benz AMG G63, a gas-powered SUV that the environmental agency says was “the worst-performing vehicle of the more than 1,200 models assessed by Greener Cars and has an annual fuel cost over $4,000.” Not to mention its MSRP of around $184,000. Rank Make & Model Powertrain Green Score MSRP Estimated Annual Fuel Cost* 1 Mercedes-Benz AMG G63 Gas 20 $184,000 $4,242 2 Ram 1500 TRX 4x4 Gas 22 $98,335 $3,819 3 Ford F150 Raptor R Gas 24 $79,975 $3,777 4 Cadillac Escalade V Gas 26 $152,295 $3,388 5 Dodge Durango SRT Gas 26 $74,995 $3,332 6 Jeep Wrangler 4dr 4X4 Gas 27 $35,895 $3,260 7 Jeep Grand Wagoneer 4x4 Gas 28 $91,945 $3,058 8 Mercedes-Benz G550 Gas 28 $143,000 $3,186 9 GMC Hummer EV SUV EV 29 $98,845 $1,746 10 GMC Sierra Gas 29 $37,700 $3,069 11 Chevrolet Corvette Z06 Gas 30 $114,395 $3,169 12 Mercedes-Benz Maybach S680 Gas 30 $234,300 $3,031 *ACEEE analysis using EIA data of the annual cost of driving 15,000 miles In terms of numbers, the dirty dozen of the meanest includes seven SUVs and three trucks. Lonely at the middle of the list is the sole electric, the GMC Hummer EV, which weighs in at 9,000 pounds. The council notes that “though EVs have lower emissions than similarly sized gasoline models, the Hummer demonstrates that size and efficiency, not just fuel source, are important factors in a carÂ’s environmental impact.” ItÂ’s also worth reminding prospective buyers that the average fuel cost of a vehicle on the “Greenest List” eats up only a fifth of the fuel cost of a vehicle on the Meanest List, “showing that greener options can also be more affordable.” The ACEEE also put out a "Greener List" of efficient gasoline and hybrid cars that don't require plugging in.  By the Numbers Green Cadillac Chevrolet Dodge Ford GMC Hummer Jeep Maybach Mercedes-Benz RAM Emissions Fuel Efficiency Green Automakers Truck SUV Electric Hybrid
