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".

2019 Ram 1500 eTorque Drivers' Notes Review | Filling in the gaps

When the 2019 Ram 1500 debuted earlier this year at the 2018 Detroit Auto Show, the biggest news was arguably the addition of the 48-volt mild hybrid system. Dubbed eTorque, the system is standard on V6-equipped models and a $1,450 option on trucks with the 5.7-liter Hemi V8. It's not a hybrid in the traditional sense. Despite Ram's claim that the system adds up to 130 pound-feet of torque on the V8, it only does so for a fraction of a second and doesn't actually change the engine's total output. You'd be hard pressed to notice a difference if you didn't know the system was there. But that's kind of the point. There's been a lot of confusion about what eTorque is and how the system works. Much of that falls on FCA's shoulders. The automaker didn't do a great job of explaining the whole thing, leaving us to work out much of it for ourselves. This isn't meant to boost performance, towing or payload. The Ram eTorque can't run on battery power, so don't expect a Toyota Prius with a bed and wood trim. It's here to make the truck just a little bit more efficient by improving areas where conventional internal-combustion engine's fall short. The eTorque system replaces the engine's alternator with a small, belt-driven electric motor. On the V6, the motor is part of the water pump assembly and driven by that belt; the V8 uses a dedicated belt that's separate from the other accessories. A small battery pack is mounted upright behind the rear seats inside the truck's cabin. There's also a DC-to-DC converter to charge the battery and convert 48 volts down to 12 to power the truck's normal systems. Visually, the only difference between an eTorque-equipped model and a standard one is a small metal box at the top of the engine. There's no badging and the battery pack can't be seen, even with the rear seats folded up. The system is designed to be as seamless and innocuous as possible. The auto start/stop system spins up the engine a little quicker. Shifts from the eight-speed ZF automatic transmission are a little smoother as the eTorque system smooths out and fills in the gaps. It does so for a fraction of a second, but it works its magic often. Big gains in fuel economy have already been made. It's going to take things like Ram's eTorque system to improve internal combustion engines from here on out. Editor-in-Chief Greg Migliore: I'd like to say I noticed a huge difference between the Ram eTorque and the regular Ram, but I didn't. That's how it's supposed to work.

Maxwell RHEV Prototype First Drive Review | More than meets the eye

The Maxwell RHEV looks just like any small business' panel van, sporting large vinyl graphics and unassuming steel wheels. You'd have no idea that the co-founders of the startup based out of Seattle had grafted a salvaged Voltec powertrain from a junkyard Chevy Volt into this Ram ProMaster. Somewhere, a battery pack lurks. Maxwell's co-founders, CEO Max Pfeiffer and engineer Trey Camp, open the cargo area to reveal a completely unaltered space. Both are ex-Tesla employees with a long fascination for the #vanlife movement – that their interests intersected in a hybrid cargo van isn't surprising once you start talking to them. This is their first vehicle, a salvaged ProMaster sidelined with a blown 3.6-liter Pentastar, and it's both their prototype and the only Maxwell in existence right now. That said, the company is building a low-roof version for a customer, which will be lighter, have less aero drag and therefore be more efficient. The company is just emerging from a stealth startup mode, and while their backstory is fascinating, I'm still wondering where the Volt's 18.4 kWh battery pack is. "There's nothing in the back ... we're able to get the battery underneath the floor, in the center," Pfeiffer says. Ducking my head under the side reveals, sure enough, a little underside blister that contains the battery, tucked up neatly. The other changes to the RHEV – short for Range-extended Hybrid Electric Vehicle – are minimal. He pops the hood. There are some rough edges, but the 1.5-liter, 101-horsepower engine and 48-kW motor fit comfortably on custom engine mounts and with re-routed exhaust, behind a fascia that improves aero and houses the charge port. Custom axles send power to unaltered Ram hubs and brakes. "This version, it's a little bit prototype-y," Pfeiffer says. "We've had more time to work with the CAD [computer-aided design, engineering drawings] we were able to get from GM and Chrysler, and we've done a better job packaging for production." GM already spent billions on the Voltec and its controlling software, and Maxwell can happily ride those coattails. Despite the help GM has lent Maxwell, there are no official ties. An emulator sends spoofed signals to the Ram instruments, which have a new custom-printed face. The Ram's body control module is left alone. For powertrain faults, Maxwell says the vehicle can theoretically be serviced by any Chevy dealer, and any issue with the rest of the vehicle can be handled by a Ram service shop.
