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 Mazda MX-5 Miata shows off perfect 50/50 weight balance

When I attended the first drive event for the Japanese-spec 2016 Mazda MX-5 Miata in Spain earlier this year, I was blown away – and not just by the car. I was blown away by the charts and graphs Mazda's engineers brought along, showing how every little facet of the ND Miata was finely tuned for pure driving perfection. It's like rocket science. Only cooler. One of the most important parts of the Miata package is its weight distribution. The 2,332-pound roadster must achieve a perfect 50/50 balance, with a driver inside. That's not easy. But it has to be done. Only the best for the Miata. In this video, Mazda shows off the Miata's balance by putting it on an aluminum balance beam, to see if the car stays perfectly centered. You can probably guess the outcome, but watching it all take place is super cool, especially with commentary by Mazda engineer Dave Coleman and MX-5 program manager Rod McLaughlin. How does the 50/50 balance help the Miata's handling out on the road? You'll have to wait until the embargo on driving impressions for the US-spec car lifts. We'll have the full scoop at 3:01 AM Eastern on Monday, June 1. In the meantime, get a sneak preview of the new Miata in the video below. Autoblog readers got a closer look at the 2016 MX-5 at our Cars & Coneys meet-up, and as you can see, the excitement for this car is definitely real.

2019 Mazda3 shows off factory bodykit, Miata gets a hardtop at Tokyo Auto Salon

The 2019 Mazda3 wasn't exactly lacking in the sporty style department when it was shown last month in L.A. But everyone, including Mazda, knows that doesn't mean it can't be even sportier. As such, the company is showing off a version of the new compact hatchback at Tokyo Auto Salon, a modified car and aftermarket parts show, with a body kit. It's a subtle one, consisting of a black front lip spoiler, black side skirts, and a longer, slightly upturned rear spoiler. Its low-key design fits in well with the Mazda3's taut, clean lines, and it makes the car look lower and more purposeful. The Mazda3 isn't the only car getting some love at the Tokyo Auto Salon. The company will display an MX-5 Miata with a removable hardtop made of carbon fiber. Now, you may remember that Mazda does offer a hardtop, but just for racing drivers. That top is a bit odd looking with a really high rear-end to clear motorsports-spec roll bars and cages. This top follows the lines of the roadster's soft top, looking much more sleek. Neither sets of parts here have been announced for production, but we wouldn't be surprised to see them show up as Mazda accessories. The Mazda3 body kit in particular seems a shoe-in, since the previous generation Mazda3 had a very similar appearance package available. The Miata top certainly seems as though it was designed with regular consumers in mind. Its future is less certain, though. For one thing, Mazda can point to the Miata RF if you want a solid roof. Then again, Mazda still offered a removable hardtop for conventional Miata roadsters even after the original power-retractable hardtop model was introduced. If it does come to market, though, expect it to be made from more affordable fiberglass and be painted in factory colors. Related Video: This content is hosted by a third party.
