The EPA has alleged that FCA installed undisclosed emissions software in about 100k Ram and Jeep diesel models [UPDATE]

Update: The text has been updated with official information from the EPA given in a press release and a conference call. Although an initial report from Reuters said the EPA will accuse Ram and Jeep of using emissions defeat devices today, that isn't quite the case. In a press release and a conference call, the EPA stated that the notice of violation sent to FCA is for the installation of eight undisclosed auxiliary emissions control devices on 2014 to 2016 Jeep Grand Cherokee and Ram 1500 models with the 3.0-liter turbodiesel V6. The violation applies to about 104,000 vehicles in total. The agency also explained that auxiliary emissions controls on vehicles are not necessarily illegal, but installing them without disclosing them to the EPA when having the vehicle certified is. Though this initial notice of violation is for installing undisclosed software, the EPA may soon also classify these emissions devices as defeat devices, as it did with the software Volkswagen used. Depending on the outcome of the investigation, there could be fines of up nearly $45,000 per vehicle involved in the notice of violation. The agency revealed that the software alters how the emissions system performs in certain situations. In controlled testing, the vehicles are compliant, but in conditions such as high speed operation, the EPA found the vehicles would produce much higher levels of NOx emissions. The EPA is continuing to investigate, and is waiting for FCA to explain why these emissions control devices are not cheating or defeat devices. In an official statement, FCA stated it is looking forward to explaining that the software does not constitute a defeat device, and has also proposed software updates to achieve compliance. During the conference call, EPA representatives also noted that the vehicles are still safe and legal to be driven, and that owners do not need to take any action yet regarding their cars. It should be noted there is no stop-sale on current models at this time. Additionally, 2017 versions of the 3.0-liter diesel FCA vehicles have not been emissions certified yet.

Cummins builds 2-millionth diesel for Ram

Ahead of a new Ram Heavy Duty that will debut sometime next year (check out the spy shots below), Chrysler and Cummins are celebrating a milestone in a 24-year partnership that has supplied the Ram pickup with diesel engines.
In its early years, the Cummins straight-six turbo diesel was rated at just 160 horsepower and 400 pound-feet of torque, and its clattering 12 valves could be heard from a mile away. Its most recent configuration still uses a straight-six layout, but displacement grew to 6.7 liters in 2007 allowing the engine to now produce up to 385 hp and a whopping 850 lb-ft of torque. While a rumored smaller Cummins engine for use in the light-duty Ram 1500 never materialized, the work-ready 6.7-liter Cummins turbo diesel accounts for 80 percent of all Ram HD sales.
Chrysler has not yet announced when and where this two-millionth engine will be on display, but you can read more about the engine and the partnership in the press release below.

Ram 1500 TRX too tame for you? Hennessey cranks its Hemi V8 to 1,012 horsepower

Ram captured the top spot on the horsepower podium when it released the Hellcat-powered 1500 TRX in 2020. The truck's 702-horsepower output places it comfortably ahead of the Ford F-150 Raptor, at least for now, but American tuner Hennessey saw plenty of room for improvement. It added over 300 horses to the TRX's cavalry. Hennessey is a master in V8-ology, so it was only a matter of time before it injected more power into the TRX. It announced two models named Mammoth 900 and Mammoth 1000, respectively, and each number vaguely corresponds to the V8's new output. The 900's 6.2-liter produces 912 horsepower and 873 pound-feet of torque, increases of 210 and 223, respectively, compared to the standard TRX. Hennessey achieved these figures by upgrading the supercharger pulleys and making relatively basic changes to the intake and exhaust systems. Stepping up to the 1000 unlocks 1,012 horsepower and 969 pound-feet of torque, numbers that give the 6,300-plus-pound truck the uncanny ability to reach 60 mph from a stop in 3.2 seconds. It flies through the quarter mile in 11.4 seconds at 120 mph. Building a pickup with supercar-like acceleration required installing a bigger, 2.65-liter supercharger, adding high-flow fuel injectors, and recalibrating the ECU. Intake and exhaust modifications are on the menu, too. Surprisingly, it doesn't sound like Hennessey made significant internal changes to the engine or to the transmission, which suggests the standard components can handle a massive amount of power. Context is useful here. Released in 2013, the fifth and final generation of the Dodge-turned-SRT-turned-Dodge again Viper took 3.3 seconds to sprint from zero to 60 mph, and it logged an 11.5-second quarter-mile time. Previewed in a computer-generated sketch, the Mammoth 1000 (shown above) also receives 20-inch wheels wrapped by 35-inch off-road tires, a 2.5-inch suspension lift, custom bumpers on both ends, extra LEDs up front, electronic fold-out steps, plus an array of model-specific emblems. Inside, Hennessey added a numbered plaque. 200 units of the Mammoth 1000 will be available for the 2021 model year, and pricing starts at $135,350 including the cost of the donor truck (which carries a base price of $71,790) and a warranty valid for two years or 24,000 miles. Put another way, you get 30.6% more power than stock for about 40% more money.
