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.

Mazda2 sedan images released ahead of Thailand reveal

Mazda will let customers put some junk in the trunk of its Mazda2 with the introduction of a new four-door model at the upcoming Thailand International Motor Expo on November 28. While the show is still days away from beginning, the Japanese automaker is already spilling some of the details about the sedan variant of its fetching subcompact. The four-door and traditional hatchback versions of the Mazda2 will both hit Thailand in early 2015. The two of them are essentially identical other than the added trunk and adjusted rear styling for the sedan. It basically makes the model look like a shrunken down version of the Mazda3 sedan, which isn't a bad thing at all. The company has big expectations for the little car because they're already Mazda's bestselling passenger models in Thailand. Both models will be sold with the SkyActiv-D 1.5 diesel in Thailand, which gives them lower taxes under the government's low-emission, compact car incentive plan. According to a previous rumor, a gasoline-fueled mill could join the lineup eventually, too. There's also gossip that the Mazda2 sedan could eventually be sold in Australia and Europe, but US sales are still a mystery. When asked about the four-door here, Mazda spokesperson Eric Booth told Autoblog, "We'll have more to say on Mazda2 at a later date. Right now, our focus is on the launches of the all-new CX-3 and MX-5 as well as the refreshed CX-5 and Mazda6." The company is showing all of those models at this week's Los Angeles Auto Show. Mazda to Debut the All-new Mazda2 Sedan at Thailand International Motor Expo - Goes on sale in Thailand alongside the hatchback model early 2015 - HIROSHIMA, Japan-Mazda Motor Corporation will debut the sedan model of the all-new Mazda2 (known as Mazda Demio in Japan) at the Thailand International Motor Expo 2014*1 on November 28, 2014. The all-new Mazda2 compact sedan features handsome proportions and bold styling, a high-quality, sporty interior and a combination of excellent driving performance and outstanding environmental and safety performance. The all-new Mazda2 hatchback will also be exhibited at the expo; the first time the model has been displayed to the public in Thailand. Both the sedan and the hatchback feature the SKYACTIV-D 1.5, Mazda's newly-developed small-displacement clean diesel engine. The all-new Mazda2 goes on sale in Thailand in early 2015.

2014 Mazda3 configurator zoom-zooms to life

The 2014 Mazda3 is probably going to be on a lot of shopping lists, thanks to its striking good looks, clean interior treatment, fuel economy and driving character. If it happens to be on your personal list of new cars to test, you'll be happy to see that the configurator for Mazda's newest product has officially gone online.
In terms of build-your-own web items, configuring a 3 isn't much of a departure from the rest of the Mazda range. Most of the work comes from choosing one of the three trim levels - Sport, Touring and Grand Touring - and selecting either the 155-horsepower, 2.0-liter, Skyactiv four-cylinder or its larger sibling, the 184-horsepower, 2.5-liter, Skyactiv four. From there, a simple range of color and interior finishes are available, before a slim list of packages, options and accessories. Really, Mazda's made it easy to get through this build process.
