Ram boosts Heavy Duty truck claims for 2015 [w/video]

The heavy-duty truck segment boasts some of the tightest competition of any automotive niche in the US. Being able to tout just one best-in-class figure can be a marketing advantage over competitors, and Ram Trucks is adding one more accolade to its tally with a powertrain update for the 2015 Ram 2500 and 3500 Heavy Duty pickups. Ram now claims best-in-class ratings for torque, towing and payload, depending on configuration.
The major change comes for the 3500 HD with a boost in torque for its Cummins 6.7-liter, inline-six diesel engine. It now produces a meaty 865 pound-feet of twist, a boost of 15 lb-ft, which is the best figure in its segment, according to the company. To eek out the extra power, the mill has more aggressive fuel delivery, and the turbo has been recalibrated. Of course, more grunt would be meaningless if drivers couldn't do anything with it, and the tweaks help allow payload to grow to 7,390 pounds, up from a rating of 7,320 pounds last year. The max towing rating remains unchanged at 30,000 pounds, though.
The rest of the powertrain lineup carries over from last year. The base HD mill is the gasoline-fed 5.7-liter V8 with 383 hp and 400 lb-ft and a six-speed automatic. The next step up is a 6.4-liter V8 with 410 hp and 429 lb-ft. There are also three trims of the 6.7-liter Cummins diesel starting with 350 hp and 660 lb-ft with a six-speed manual gearbox. If buyers opt for a the 68RFE six-speed auto, they get 370 hp and 800 lb-ft. Finally, there's the updated, top-rung version with 385 hp and 865 lb-ft with an Aisin six-speed automatic transmission.

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.

Stellantis aims to eliminate separate inverter, charger to improve EV efficiency

Stellantis has announced that, in collaboration with French battery company Saft and French National Center for Scientific Research, has made significant progress in eliminating two major components of an electric vehicle powertrain: the on-board charger and the power inverter for the motor. The company claims that doing this will allow for better space use in vehicles, as well as improvements in efficiency, cost and reliability of components. As a quick primer, also explained in the below video, the on-board charger and power inverter are sort of translators to get the right current to different parts of the electric powertrain. The on-board charger takes AC power from the grid and converts it to DC to charge the batteries. Then when power goes from the batteries to the electric motor, the power inverter converts that DC power back to AC. These components aren't exactly small. Frequently you'll find them packaged somewhere under the hood. What Stellantis and its cohorts have developed, and have been using on a test vehicle since last summer, are small power inverter boards that can be mounted very closely to the battery packs. They can handle both conversion needs, for charging and discharging, instead of needing two separate devices. The most obvious perk to this is that you can do away with those traditional components and free up more space, either for making smaller vehicles without losing interior volume, or adding space to a vehicle that wouldn't have had it otherwise. There's the additional benefit of reduced weight, something that EVs struggle with. Stellantis also claims improvements in efficiency, reliability, and cost, however, it didn't go into detail as to how this setup would do that exactly. We'll try to get in touch with representatives from Stellantis in order to get more information. We're still a ways out from seeing this technology in production Stellantis vehicles. The company said it aims to apply it to vehicles by the end of the decade. Saft is also looking at using it on stationary battery systems as well. So maybe we'll see it on a 2029 Ram 1500 REV, but for now, we'll be living with traditional chargers and inverters. Related Video: Green Alfa Romeo Chrysler Dodge Fiat RAM Technology Electric
