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 a knight in white satin

We're not going to lie to you. The reason you're seeing the fourth-generation Mazda MX-5 Miata on these pages again is solely because this is the first time we're seeing the roadster displayed in a color other than the ruby shade it was first shown in. Okay, okay, so this is the first time the Miata is being displayed at a North American auto show other than SEMA, and we'd say that this is the first time Mazda is showing a US-spec model, but clearly this is a right-hand-drive car. Either way, there's still not much to it yet, especially since Mazda is still withholding power and performance figures.
As expected, the ND Miata, as it is already known among the cognoscenti, will receive a 2.0-liter Skyactiv four-cylinder and the buyer's choice of a six-speed manual or a six-speed automatic here in the US. The 1.5-liter model engine that had been linked to the car back in the rumormill stage will not make it to our showrooms.
Preliminary specifications still show the Miata measuring just 154.1 inches in length overall, with an increased track width to 68.1 inches and a low, low overall height of 49.0 inches. Despite the larger-displacement engine and its presumably heavier weight, Mazda is still claiming ideal 50:50 weight distribution and a weight loss of over 220 pounds versus today's NC generation. All of which sounds like the Miata has the right ingredients to make good on its promised Jinba Ittai ("rider and horse as one") driving experience.

Mazda CX-6: How a wagon could sell better than the Mazda6

There is no Mazda CX-6. It doesn't exist, nor have we talked to anyone at Mazda about its existence. However, let me now say that there SHOULD be a Mazda CX-6, or to put it another way, a Mazda6 Wagon that's been Allroad-ified with a modestly raised suspension, plastic body cladding and all-wheel drive. You know, the way Americans prefer their wagons. During the Regal TourX launch, Buick's product planning folks pointed out that such a crossover wagon (let's go with that term for now) filled a market niche that's really not being satisfied. One that's more stylish and luxurious than a Subaru Outback, but more functional and less expensive than an Audi Allroad. It would cater to people who seek something different from the norm, both in terms of brand and body style. Sure, it's certainly not a big market niche, but it is seemingly growing. Well, if Buick is indeed onto something and that growth continues, then Mazda could most definitely go after that same market niche. Sure, it's a small niche, but all three Mazda6 generations have sold in such minuscule numbers (33,402 in 2017), why not try something completely different? I could easily see a CX-6 outselling its sedan sibling. Such a Mazda crossover wagon would only have a Buick and Subaru as competition, as opposed to trying to draw customers away from the Honda Accord, Toyota Camry and every other midsize sedan at a time when the entire segment is hemorrhaging sales. It would also nicely complement a lineup of crossovers that includes the CX-3, CX-5 and CX-9, providing yet another alternative to entice customers.

I'd argue the Mazda actually has a more luxurious cabin than the supposedly "premium" Regal, while Mazda's new turbocharged 2.5-liter (250 horsepower, 310 pound-feet of torque) outdoes the Buick's potent 2.0-liter. Meanwhile, the Mazda6's standard, naturally aspirated 2.5-liter (184 hp, 185 lb-ft) should offer comparable fuel economy as the Subaru Outback (28 mpg combined) without making you suffer through a CVT. Now, as for adding all-wheel drive, the Japanese market version of both the sedan and wagon (known as the Atenza) can apparently be had with it. Can it be packaged with the turbocharged engine? That's another question, but all the other pieces are seemingly in place to bring the Mazda6 wagon to the United States.
