Tech of the Year special, plus we drive the hydrogen Mirai and more | Autoblog Podcast #809

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor James Riswick and Road Test Editor Zac Palmer. They kick the discussion off by talking about what they've been driving as of late, including the Toyota Mirai, Dodge Hornet, Alfa Romeo Tonale and a trio of subcompact SUVs. After that, they dive into a discussion about the 2023 Autoblog Technology of the Year award winner, which is Mercedes-Benz's Dolby Atmos Spatial Audio. Once they wrap up that segment, we get to hear the crew's latest Cybertruck takes from before the big reveal. Finally, the show wraps up with a fun Spend My Money segment.

Mazda files patents for a sequential twin-turbo setup

Mazda has a history of interesting engine technologies, from yesterday's rotary engine to tomorrow's compression ignition engine, and new patents show it still may have some internal combustion tricks up its sleeve. The one on display in these patents isn't especially new in concept, though. A sequential twin-turbocharger setup is something Mazda itself used on the third-generation RX-7. But it's something we haven't seen much of lately. It looks like it could have some possible advantages over older sequential systems, and it has some potential advantages for enthusiasts. First a quick and dirty primer for what makes a sequential twin-turbo system distinct from other twin-turbo systems. In many twin-turbo engines, there are simply two turbos that work together as one bigger turbo. They're the same size, and they spool up at the same time. With a sequential setup, at low rpm, a smaller turbocharger is spooled up first at low-rpm for quicker throttle response, and as the rpm and exhaust pressure increases, a valve opens up that allows a larger turbocharger to also spool up and provide high-rpm boost. That's basically how the Mazda design shown above functions. A big flap blocks off the larger turbocharger exhaust inlet, channeling all the exhaust to the smaller turbo. When more exhaust is available at high rpm, it looks like that flap opens up to spool up the big turbo, too. What's interesting here is that the way the turbochargers are packaged takes up less space than past systems. It looks like both turbos are contained in one unit that shares the same exhaust outlet, meaning the exhaust manifold could be kept simple and compact. In fact, the piping for compressed intake air could also be shared, reducing the amount of piping, which would further decrease the amount of materials and possible failure points. There are a number advantages of making this system smaller. The potential applications of the system are much greater, since it could fit in smaller cars with smaller engine bays. Making the system smaller also means that there won't be as much weight, which is important from both fuel economy and performance standpoints. Finally, the smaller setup likely uses fewer materials, which could make the system cheaper and thus easier to offer on a wider range of vehicles, or at least more profitable for Mazda.

2016 Mazda2 won't come to the US

Hoping to get your hands on the new Mazda2? Don't get your hopes up too high, because the latest word has it that the new hatchback won't be available in the United States. According to the report from Automotive News, Mazda's US office has decided against bringing the new Mazda2 to American showrooms. This despite it being made just south of the border in Salamanca, Mexico. The reasons are apparently two-fold. For starters, Mazda sales offices around the world have been clamoring for larger allotments of the new 2, and the company can only supply so many. "We could have had it, but we would have had a number that didn't make much sense with 600 dealers and with the marketing it takes to launch a new car," Robert Davis, Mazda's senior VP of US sales operations, told AN. For another, Mazda is apparently not convinced the new supermini would resonate with US buyers, who are increasingly migrating towards crossovers. So Mazda is focusing instead on "products that make us and our dealers considerably more profit than a Mazda2 does." That doesn't mean the latest Mazda2 will be entirely out of our reach forever, though. The company's agreement with Toyota will see a sedan version sold in the US as the Scion iA. Mazda is also certifying it to US safety and environmental standards so that it can sell the 2 in Puerto Rico, which means that it wouldn't take much to change course and bring the hatchback into the US in the future: "It'll always be there if we need it," Davis told AN. Reached for comment, a spokesman for Mazda's North American operations told Autoblog that "The Mazda2 launch in the U.S. market is on hold in order to evaluate the B-Car segment and enable us the opportunity to focus on the launches of the refreshed Mazda6 and CX-5, and the all-new MX-5 roadster and CX-3 subcompact crossover SUV." That leaves the aforementioned CX-3 - which is, incidentally, based on the same architecture as the Mazda2 - as the smallest mainstream model that Mazda will offer Stateside.
