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

Chrysler's Hurricane engine detailed ahead of 2016 launch

We've been hearing distant rumblings about Chrysler's new Hurricane engine for some time now, but details have been hard to come by. Now, Automotive News is adding some specifics to the scuttlebutt, citing Chrysler documents. According to the industry publication, the Hurricane will blow onto the scene in 2016, but it's not an all-new engine. Rather, it will be rooted in the company's existing 2.0-liter four-cylinder Tigershark powerplant (shown above), albeit with "many new technologies to achieve excellent fuel economy."
It's not clear what sort of technologies Chrysler is referring to, but the Hurricane is expected to continue to use an aluminum block, and the finished product is expected to generate even better figures than the existing 2.0-liter's 160 horsepower and 148 pound-feet of torque (as found in the Dodge Dart). Automotive News notes that the updated 2.4-liter Tigershark debuting in the entry-level 2014 Jeep Cherokee has its basis in the 2.0-liter lump, but unlike the smaller engine, it's been fitted with MultiAir2 electrohydraulic variable valve timing to realize 184 hp and 171 lb-ft and greater efficiency.
Perhaps the Hurricane will incorporate the latter in its bag of tricks? Either way, we're hoping for a more generous torque curve than the what's in the current 2.0-liter Tigershark, which is something of a slug in the Dart - even for a base economy compact.

FCA goes all-in on Jeep and Ram brands on cheap gas bet

It's no surprise that as SUV and truck sales remain strong in the wake of unusually cheap gas, Jeep and Ram sales are taking off. What is a surprise is that FCA CEO Sergio Marchionne thinks that cheap gas will be a "permanent condition," and feels strongly enough about it to change up North American manufacturing plans. Jeep appears to be the biggest beneficiary of the product realignment. In addition to increasing the sales estimates for the brand worldwide upwards to 2 million units a year by 2018, the brand will get a flood of investment for new product and powertrains. Consider the Wrangler Pickup to be part of the salvo, as well as the Grand Wagoneer three-row announced in 2014 as part of the original five-year plan. The Wrangler four-door will get at least two new powertrains, a diesel and mild hybrid version, in its next generation. That mild hybrid powertrain may utilize a 48-volt electrical system like the one that's being developed by Delphi and Bosch – which the suppliers think will be worth a 10 to 15 percent fuel economy gain at a minimum. Down the road, in the 2020s, the Wrangler could adopt a full hybrid system. The diesel powertrain is planned for 2019 or 2020. The Ram 1500 is also pegged to receive a mild hybrid system, again potentially based on 48-volt architecture, sometime after 2020. Lastly, Jeep and Ram will take over some of the production capacity of existing plants. The Sterling Heights, MI, plant that builds the Chrysler 200 will now build the Ram 1500; the Belvidere, IL, facility that produces the Dodge Dart will take over Cherokee output; the big Jeep facility in Toledo, OH, will be used for increased Wrangler demand. In 2015, according to FCA's numbers, car and van demand went down by 10 percent, but SUV demand went up 8 percent and truck demand 2 percent. Considering that these are high-margin vehicles, FCA can't ignore the math. FCA also won't build any new factories to supplement production to meet demand, but instead are reshuffling production priorities. Think of it this way: FCA is gambling on cheap gas being a permanent part of our lives, at least into the 2020s. By doubling down on SUVs and trucks, the company stands to win big, unless a spike in gas prices changes the landscape. FCA isn't talking about a Plan B, so they're all in. It'll be interesting to see how this plays out.
