2023 Honda Pilot and the promise and pitfalls of PHEVs | Autoblog Podcast #766

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Associate Editor Byron Hurd for a chat about the new 2023 Honda Pilot and its beefed-up TrailSport model. After that, we get a winter-weather long-term update on the BMW 330e care of Greg. Then, it's on to news. The big headlines this week were the brand-new Mazda CX-90 crossover and word that Genesis plans to build its outrageous (and expensive) X convertible concept.

2014 Mazda3 Sedan

Playing Favorites
We're not going to beat around the bush: for the kind of person who willfully chooses to take longer, windier and more scenic routes to get to Point B, the 2014 Mazda3 is the new compact car measuring stick by which others will be judged. That doesn't, of course, make it the right choice for every buyer.
We'll spend the next thousand words or so explaining the whys and hows that make our opening statement a fact, but for now, suffice it to say that Mazda has engineered its latest crop of vehicles - namely the CX-5, Mazda6 and its smaller sibling and subject of this test, the Mazda3 - from the ground up. Absolutely everything about the Mazda3 is refined for 2014, from its chassis to its engines and everything in between, and it was done in a completely new and holistic way. Every component, subcomponent and stamping required to bolt and weld together an automobile was rethought to ensure the Mazda3 has what it takes to compete with such established benchmarks as the Honda Civic and Ford Focus.

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.
