Porsche 911 Carrera 4, Alfa Romeo Giulia Quadrifoglio and a chat with Jean Jennings | Autoblog Podcast #626

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Road Test Editor Zac Palmer, Associate Editor Byron Hurd and special guest Jean Jennings. The gang kicks off with a discussion about the cars they've been driving — 2020 Porsche 911 Carrera 4, 2020 Alfa Romeo Giulia Quadrifoglio and the 2020 VW Tiguan. They shift gears to talk about the latest news gleaned from a press conference concerning the 2021 Supra, then, they reach into the mailbag to help a listener buy a performance car. Lastly, Greg has a chat with special guest Jean Jennings.

The 2020 Alfa Romeo Giulia's infotainment system is new, but is it better?

When Alfa Romeo introduced the Giulia in 2017, it was praised for its its on-road manners, its gorgeous styling and its performance credentials. It was criticized for, well, just about everything else, including a clunky, low-resolution and feature-light infotainment system. Enthusiasts can forgive many of a car's flaws so long as the driving experience is stellar, and for that reason, the Giulia quickly became a darling. But Alfa can't depend on enthusiasts alone to buy its cars; they need to be seen as legitimate players in the luxury market, and to do that, they need interior tech and materials to match their price points.  For 2020, Alfa Romeo addressed the Giulia's shortcomings. The infotainment system was overhauled, with a new 8.8-inch touchscreen headlining a host of additional features. The Giulia now has acoustic glass for a quieter, more luxurious cabin, and some much-needed material improvements on the steering wheel, dash and center console. There's also a new USB Type-C outlet, a wireless device charging option and some other behind-the-scenes features, like a wireless hot spot and over-the-air firmware update capabilities.  The Giulia's original infotainment system was criticized for its low-res screen with no touch interface, a lack of quick access buttons for key features, and a lack of depth when it came to integrated tech. On paper, Alfa has addressed all of these shortcomings, but I wanted to see how it performs in the real world. To do this, I set aside some time with the 2020 Alfa Romeo Giulia Quadrifoglio to dedicate solely to exploring its new tech features. What I found was a bit of a mixed bag.  Let's start with the interface itself. The 8.8-inch screen used to be an upgrade, but the extra real estate is now standard and, as we mentioned up top, it's now a touchscreen. Both the resolution and the quality of individual page graphics have been significantly improved compared to the old software. Alfa says the underlying hardware was improved to support the improved visual experience.  Improved, perhaps, but not perfected. The interface still lags inputs (especially touch) and lacks a crisp, responsive feel. Even after the system has fully loaded, there's a visible delay between finger gestures and responses from the interface.

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
