Weekly Recap: Ferrari, Ford and Porsche power up for Geneva

Monday was Groundhog Day. Tuesday, apparently, was Sports Car Day. The Ferrari 488 GTB, the Ford Focus RS and the Porsche Cayman GT4 all debuted within hours of each other ahead of their rollouts at the Geneva Motor Show. Three sporty machines, three vastly different approaches – and a lot of implications for enthusiasts. That's a day worth repeating. It also illustrates the opportunities automakers see in the performance market, which is expected to grow in the coming years. Ford estimates the segment has expanded 14 percent in Europe and surged 70 percent in North America since 2009. The Detroit Auto Show was evidence of this, and performance cars of every stripe debuted, including the Acura NSX, Ford GT, Alfa Romeo 4C Spider and several others. This isn't a fad. Performance cars aren't going away. The question is why? Stricter CAFE standards are looming in the United States, as are tighter emissions regulations in Europe. And no one expects gas prices to remain low in America. None of this matters for sports cars, and automakers are increasingly using them to elevate their images. That's why Dodge rolled out two 707-horsepower Hellcats last year. It's why Ford has decided to resurrect the GT for road and track. It's why in the depths of bankruptcy, General Motors continued work on the Chevrolet Corvette Stingray, not to mention the Z06. "Great brands are made one car at a time," Ford of Europe president Jim Farley said at the reveal of the Focus RS. Still, companies make those cars for different reasons. View 5 Photos Mainstream brands like Ford and Dodge want to build cars that get people talking, excite their bases and drive more potential customers into the showroom. They probably don't buy a Focus RS or a Hellcat, but suddenly the regular Focus hatch looks a bit hotter, and that V6 Charger seems to be just a touch more muscular. The halo of performance is alive and well in the eyes of automakers and their customers. "It's one of the most effective catalysts for ingenuity and innovation," said Joe Bakaj, vice president of product development for Ford of Europe. That also leads to a trickle-down effect. Some of the technologies inevitably make their way to other products. It's hard to think the new all-wheel-drive system in the Focus RS that distributes torque front to rear and side to side won't be used in other vehicles. It's different for Ferrari and Porsche.

Solid-state batteries: Why Toyota's plans could be a game-changer for EVs

Word out of Japan today is that Toyota is working on launching a new solid-state battery for electric vehicles that will put it solidly in the EV game by 2022. Which leads to a simple question: What is a solid-state battery, and why does it matter? Back in February, John Goodenough observed, "Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted." And risking a bad pun on his surname, he seemed to be implying that all of those characteristics weren't currently good enough in autos using lithium-ion batteries. This comment is relevant because Goodenough, professor at the Cockrell School of Engineering at the University of Texas at Austin - it so happens, he turns 95 today - is the co-inventor of the lithium-ion battery, the type of battery that is pretty much the mainstay of current electric vehicles. And he and a research fellow at U of T were announcing they'd developed a solid-state battery, one that has improved energy density (which means a car so equipped can drive further) and can be recharged more quickly and more often (a.k.a., "long cycle life") than a lithium-ion battery. (Did you ever notice that with time your iPhone keeps less of a charge than it did back when it was shiny and new? That's because it has a limited cycle life. Which is one thing when you're talking about a phone. And something else entirely when it involves a whole car.) What's more, there is reduced mass for a solid-state battery. And there isn't the same safety concern that exists with li-ion batteries vis-a- vis conflagration (which is why at airplane boarding gates they say they'll check your carryon as long as you remove all lithium-ion batteries). Lithium-ion batteries may be far more advanced than the lead-acid batteries that are under the hood of essentially every car that wasn't built in Fremont, Calif., but as is the case with those heavy black rectangles, li-ion batteries contain a liquid. In the lithium-ion battery, the liquid, the electrolyte, moves the lithium ions from the negative to the positive side (anode to cathode) of the battery. In a solid-state design, there is no liquid sloshing around, which also means that there's no liquid that would freeze at low operating temperatures. What Toyota is using for its solid-state battery is still unknown, as is the case for the solid-state batteries that Hyundai is reportedly working on for its EVs.

Join Autoblog editors for a full video tour of the 2019 Detroit Auto Show

The 2019 North American International Auto Show might have been a little more quiet than past years, but there were still some pretty major reveals, including the Toyota Supra, new Ford Explorer, Shelby GT500, Subaru WRX STI S209 and Kia Telluride. We also saw some lovely concepts like the Nissan IMs and Lexus LC Convertible. Senior Editor Alex Kierstein, Consumer Editor Jeremy Korzeniewski and Senior Green Editor John Beltz Snyder join me, Associate Editor Reese Counts — with Social Media Manager Michael Dylan Ferrara behind the camera — on a long walk through the show. We discuss cars, poke around the stands, dress a bloody wound and answer your questions in the Facebook comments. For more Detroit coverage, you can check out Autoblog's picks for the best in show, listen to our podcast or look at the best images from all the reveals. Finally, don't forget to watch Editor-in-Chief Greg Migliore hand over our 2019 Technology of the Year award.
