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.

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

2020 Ram 3500 heavy duty interior spied

The 2020 Ram 2500 and 3500 trucks continue their steady testing regimen, and the engineers are still keeping the trucks under careful wraps. Or at least they are with the outside. As the photos above show, some test drivers got a little sloppy with interior coverings, and our spy photographer took advantage of the situation. And the good news is that the interior will be basically identical to that of the 2019 Ram 1500. We say good news because the Ram's stylish interior and well-thought-out controls are part of why it's our favorite fullsize pickup right now. This particular model has the 8.4-inch UConnect touchscreen infotainment. Since the entire center stack is the same as the 1500, we wouldn't be surprised if the monster 12-inch display were to be available on high-end trims. The small 5-inch infotainment will probably be the standard option. Another interesting detail is that this test truck does not have the rotary shift dial shared with the Ram 1500 and various other Chrysler products. Instead, it has a traditional steering column-mounted shift lever. As for the outside, nothing new is revealed to us. We shouldn't have to wait too long to see the production truck, though. We expect it to be revealed early next year. What we've seen so far seems to indicate that the heavy duty Rams will have styling a little closer to the old model than to the new 1500. Still, expect grilles and other cues from the lighter duty model, just translated to a slightly different shape. Related Video: This content is hosted by a third party.
