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

2019 Ram HD Chassis Cab trucks: tough on the outside, comfy on the inside

The past year or so has been big for Ram. FCA's truck division went from having some of the most dated (though still solid) pickups on the market to introducing the 2019 Ram 1500, arguably the new segment leader. A year later, at the 2019 Detroit Auto Show, FCA revealed the new Ram Heavy Duty. Yesterday, Ram announced the 1500 was getting a trick tailgate to compete with the power tailgate on the Chevy Silverado and MultiPro tailgate on the GMC Sierra. Today, at the 2019 Chicago Auto Show, FCA will present the new Ram 4500 and 5500 chassis cab models. Like the Ram 2500 and 3500, the new chassis cab trucks appear to share a lot with the current crop of Ram HD trucks. The cab itself appears to be unchanged from the outside, though the front fascia has been updated to reflect Ram's current design. As with most things, it's what's inside that counts. The chassis cab models get the fantastic interior from the 2019 Ram 1500. It's a handsome and well-appointed cabin. Even base Tradesman models benefit from the new design and packaging. There's new tech, too. The 12-inch infotainment screen is nice to look at, but customers are likely to enjoy features like adaptive cruise control, forward collision warning and automatic emergency braking (with trailer brakes). The safety tech is available on all trim levels. The trucks also pack parking assist and a 270-degree camera view. There are also camera features to help hook up trailers (including fifth-wheel goosenecks). The Ram Chassis Cab 3500, 4500 and 5500 represent Class 3, 4 and 5 GVW ratings. As such they pack some punch under the hood. The standard engine is the 6.4-liter Hemi V8 making 410 horsepower and 429 pound-feet of torque, though 4500 and 5500 models only make 370 horsepower. The Ram 3500 features cylinder deactivation to improve fuel economy. The three trucks are available with a 6.7-liter Cummins turbo-diesel inline-six. The engine makes 360 horsepower and 800 pound-feet of torque. An Aisin six-speed auto is available on V8 models and standard with the diesel. Both engines are available with dual alternators. The trucks are available in four industry-standard frame lengths measured in inches from the cab to the rear axle: 60, 84, 108 and 120. Upgraded brakes should shorten stopping distances and improve pedal feel. Thanks to high-strength steel and aluminum, the truck should weigh about 120 pounds less than before.

Color match your 2018 Ram to your tractor with new Harvest Edition

Though pickup trucks have become increasingly civilized and more common in cityscapes, they're still indispensable equipment as work vehicles, especially on farms. Recognizing this, Ram created a truck package aimed specifically at the agricultural sector called the Harvest Edition. The package features a variety of equipment as standard, like mud flaps, side steps, a rear bumper step, skid plates, rubber floor mats, a spray-in bedliner, 4G WiFi, navigation, and access to weather via Sirius radio. Rams with four-wheel drive also get tow hooks, and 1500 models receive a one-inch suspension lift. Ram 2500 and 3500 retain their normal ride heights. The Harvest Edition includes visual enhancements, most notably the addition of Case IH red and New Holland blue paint colors. But if you prefer John Deere, you won't find its signature green – instead you'll have to settle for white, black, or silver. The Harvest Edition features loads of shiny trim. The mesh grille is chrome, the mirrors and door handles are chrome, the bumpers are chrome. The wheels are chrome on 1500s, and simply polished on heavy duty models. The only visual changes that doesn't involve shiny metal are the body-color fender flares. The package is available on all four-door Ram trucks from 1500 to 3500. It's also available with two- or four-wheel drive and every engine option from V6 to Cummins diesel. The 1500 model starts at $41,305, and the 2500 starts at $47,630. The package becomes available in the third quarter, so farmers and even wannabe farmers should be able to pick one up very soon. Related Video:
