An early gas-electric hybrid was developed by...Exxon?

We're not sure which aspect of Exxon's 1970s-era efforts to develop advanced and electrified powertrains is the most ironic. There's Exxon, that of the Valdez oil spill infamy, being on the leading edge of hybrids and electric vehicles. There's a boat-like Chrysler Cordova getting 27 miles per gallon. And there's the central role a Volkswagen diesel engine plays in that hybrid development. It's all outlined in an article (linked above) by Inside Climate News, and it's an amusing read. Flush with cash and fearing what it thought was peak oil production in the 1970s, Exxon funded a host of new ventures divisions geared to find alternatives to gas-powered powertrains. In the early 1970s, Exxon lured chemist M. Stanley Whittingham to develop what would become a prototype of a lithium-ion rechargeable battery. Then, in the late 1970s, Exxon pioneered the concept of using an alternating-current (AC) motor as part of a gas-electric hybrid vehicle. The company retrofitted a Chrysler Cordova (yes, that's the model Ricardo Montalban used to hawk) with a powertrain that combined 10 Sears Die-Hard car batteries, an alternating current synthesizer (ACS), a 100-horsepower AC motor, and, yes, a four-cylinder 50-horsepower Volkswagen diesel engine. The result was a rather large two-door sedan that got an impressive 27 mpg. And while US automakers didn't see the potential in the early concept, in 1980 Exxon and Toyota began collaborating on a project that would involve retrofitting a Toyota Cressida with a hybrid engine. That car was completed in 1981, and may have been one of the seeds that eventually helped sprout the concept of the Toyota Prius. Soon after rebuilding the Cressida, Exxon would get out of the advanced-powertrain-development business, as oil prices began to fall in the early 1980s, spurring cost-cutting measures. Cry no tears for the Exxon, though, as what's now known as ExxonMobil is the largest US oil company.

Are old airbags killers?

Takata airbags may not be the only ones with some very serious problems. A new report from TheDetroitBureau.com claims that the National Highway Traffic Safety Administration has opened its second investigation into bad airbag inflators, and this time, they aren't from Takata. The focus of this latest case is on the airbag inflators in some 500,000 older Chrysler Town and Country minivans and Kia Optima sedans, all of which come from ARC Automotive. While the Takata case looks at problems stemming from the engineering and production process, the ARC investigation focuses on the age of the inflators. As TDB explains, airbag inflators are essentially what the military refers to as shaped charges, sort of like Claymores (for fans of the Call of Duty series). In combat, they blow up in a specific direction, protecting those behind the explosion, although in the case of airbags, the explosion "[creates] a precise rush of hot gases" that inflate the bags. NHTSA's worry is that with the increased average age of today's vehicles, years and years of being bounced, jolted, and shaken about and exposed to often-radical temperature changes have altered the nature of the explosives in these vehicles, causing too big of an explosion. "It may be a reasonable assumption that as these things age they deteriorate." – Analyst George Peterson "It may be a reasonable assumption that as these things age they deteriorate," analyst George Peterson told TheDetroitBureau.com. NHTSA boss Mark Rosekind backed up aging angle. "Cars are lasting on the road a lot longer than ever before," Rosekind told TDB, adding that seals could start breaking down. "Is aging now an issue? That's part of the investigation going on." NHTSA has only identified two "incidents" so far, although according to Center for Auto Safety Director Clarence Ditlow, there's genuine concern that there could be additional unidentified cases. "Could we have missed more? That could be the case," Ditlow told TDB, citing the misidentified deaths in the Takata investigation. Ditlow was quick to point out that, even in older vehicles, airbags are much more likely to protect than harm. "No one is saying you should disable your airbags," the safety advocate told TDB. "You're far more likely to be helped than hurt by one if they go off." At least one automaker, meanwhile, has already been advised of the investigation by NHTSA and is checking its airbags.

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
