FCA UConnect fiasco could set over-the-air updates back years

Since cars have become more software dependent, most major automakers have been inching toward enabling over-the-air updates to keep vehicle electronics, ranging from infotainment systems to safety features, current. But there are only two car companies — Fiat Chrysler and Ford —± currently doing OTA updates, and on a limited basis. GM CEO Mary Barra announced last summer that the automaker will launch a new EV architecture and infotainment system capable of over-the-air updates "before 2020." The one exception, per usual, is Tesla. Since the release of the Model S almost six years ago, the maverick EV automaker has made routine OTA software updates a core part of its vehicle platforms and value proposition, and has sent out updates for everything from adjusting ride height to enabling Autopilot, largely without incident. When I've asked automakers why they can't do the same thing, I've heard reasons ranging from running afoul of their dealers (and archiac regulation) to security concerns. Automakers like Ford and General Motors say they want to act like tech companies, which routinely send out OTA updates for a wide range of devices, but overall the car industry still moves at a very cautious snail's pace. And when automakers do try to move faster and take more risks — unlike with a smartphone update, which people bitch about but live with — the consequences can be significant when things go wrong. That's the case with Fiat Chrysler America and its recent public-relations nightmare when an OTA update went awry. The update went out at the end of last week for the Uconnect system in late-model vehicles, and it made head units go into a near continuous reboot, which caused owners to not only lose access to entertainment features, but also critical functions like emergency assistance. Almost immediately, owners took to Twitter to express outrage, and FCA was caught flatfooted. A tweet went out on Monday on the UconnectCares Twitter account that read, "Certain 2017 & 2018 Uconnect systems may experience a reboot every 45-60 seconds. Our Engineering teams are investigating the cause and working towards a resolution.

Tesla Model S P85D shows 707-hp Dodge Challenger Hellcat how to drag race

Street Car Drags hosted a bang-up event at the Palm Beach International Raceway last weekend, with a list of massive horsepower ICE cars going up against one another and a trio of Tesla Model S P85Ds. One of those duels pitted the 691-horsepower Tesla against a 707-horsepower Dodge Challenger SRT Hellcat, and the result was an old-school beatdown and a world record for electric cars. The Model S P85D ran the quarter in 11.6 seconds at 114.6 miles per hour, the new mark for BEVs at the drag strip. Proving its pace, it ran three more times in 11.69, 11.72 and 11.76 seconds. It got from the start line to 60 miles per hour in 3.1 seconds. The Hellcat, well, it wasn't a race, really. It was the Hellcat's driver's first time at a drag strip and his first time trying to launch it, so after an excellent burnout ahead of the lights, he rolled to the line, almost jumped the start, balked at the real start and spun his tires for the first 100 feet down the strip. The theory is that he overheated his street tires during that burnout, and the resulting greasy rubber did what greasy rubber does. By the time he got to the other end 17.46 seconds later the Tesla driver had showered and was enjoying a funnel cake. When things go right, though, Dodge estimates the Hellcat will do 11.2-second runs on street tires and it has been clocked at 10.85 seconds at 126.18 mph on street-legal drag radials. There's video of the not-quite-a-race above, and Drag Times says there'll be a rematch between the two in a couple of weeks.

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
