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.

Laguna Seca getting another awkward name with WeatherTech sponsorship

According to the Monterey Herald, and also reported by Autoweek, Laguna Seca is getting a new title sponsor and as a result, a new name. The track is currently known by the official name of Mazda Raceway Laguna Seca, a less-than-elegant name that goes away soon because Mazda is ending its sponsorship on March 31. The newspaper reports that the new sponsor is WeatherTech, and the new name, arriving on April 1, adds a word: WeatherTech Raceway at Laguna Seca. We're not sure why it can't simply be known as Laguna Seca, since that's the name that sticks after the sponsors disappear. And we don't know why adding a word is better. Why would you add syllables to say and letters to type (insert lazy writer joke here)? It seems that those in charge of the track are happy with the deal, though. The Monterey Herald reports the deal is for five years of sponsorship at a cost of $5 million and that it's about two-thirds of what Mazda was paying. But the newspaper also reports that the track won't be providing the same track access that Mazda needed, and it may attract other automakers to the track when the track's name isn't partly that of a competitor.

2014 Mazda3 breaks cover early, in Euro-spec at least

We're set to get a closer look at the US-spec 2014 Mazda3 later today, but AutoExpress has the first peek at the machine's European cousin (after initial leaks reportedly came from a Czech outlet). The photos show a compact that's taken plenty of design inspiration from its older sister, the Mazda6. That's excellent news, as the larger car's dynamic front fascia, accentuated fender arches and long nose translate well to the Mazda3. Inside, there are are new and improved material choices, and the longer wheelbase means occupants get to enjoy more room than before. There's also a larger trunk with 12.3 cubic feet of cargo capacity.
Buyers in the EU can get their hands on a 1.5-liter Skyactiv-G gasoline engine with 99 horsepower, though the old 2.0-liter four-cylinder will still be available in either 118 hp or 163 hp configuration. A 2.2-liter diesel tops out the engine choices.
The 2014 Mazda3 is lighter than its predecessor and boasts disk brakes and a multi-link rear suspension on every trim. That means this thing should be fun to shuffle around. Stay tuned for details on the US-spec variant later today, including a lot more images of the good-looking hatch.
