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.

2021 Mazda CX-3 gets a few more features, costs same as in 2020

The Mazda CX-3 is still down there at the foot of the Mazda lineup, chugging into 2021 and its seventh year on sale. The subcompact hatchback hasn't been overhauled since its debut and in 2020 had its three trims rationalized to one trim, so it gets denied the attentions paid to the Mazda3 and the CX-30. Those with an eye on the CX-3, however, will pay the same amount in 2021 as buyers did in 2020. Mazda announced a base price of $20,640 for the sole CX-3 Sport model, for a total of $21,740 after the $1,100 destination charge. Going from a Sport FWD to the Sport AWD adds $1,400, coming out to $23,140. Mazda's littlest crossover is powered by a Skyactiv-G 2.0-liter four-cylinder producing 148 horsepower and 146 pound-feet of torque, shifting through a six-speed automatic. The nicer, newer, larger CX-30 is powered by a Skyactiv-G 2.5-liter inline-four that it shares with the Mazda3, producing 186 horsepower and 186 pound-feet of torque and mated to a six-speed auto. The front-wheel drive CX-30 starts at $23,000 after destination, $1,260 above the CX-3, the AWD CX-30 maintaining the same price gap at $24,400.    Related: Least expensive vehicles to insure in America   New for the 2021 CX-3, the i-Activsense suite has been updated with night pedestrian detection for the low-speed forward collision alert and avoidance system, and the LED headlights are self-leveling with enhanced auto on/off activation. The standard driver safety systems also include adaptive cruise control, automatic emergency braking, blind spot warning with rear cross-traffic alert, and lane departure warning. There's a seven-inch touchscreen infotainment system with Mazda Connect, Android Auto, and Apple CarPlay, and remote keyless illuminated entry thrown in, too. The Sport trim goes with a louver-styled grille, roof spoiler, and 16-inch alloys. In fact, other than the cost-extra colors Machine Gray Metallic, Snowflake White Pearl Mica, and Soul Red Crystal Metallic on the eight-strong exterior palette, and some minor cosmetic options, the basic CX-3 is the only CX-3. It will reach dealer lots next month. Related Video:

Mazda Hazumi concept presages next Mazda2

Looks like Mazda's big Geneva Motor Show debut is actually something quite small. Teased here, the Hazumi concept "points the way to the future" for the brand's subcompact offering, the Mazda2. Details are slim as of this writing, but from what we can see in the image above, the Hazumi will use the same Kodo design language found on the Mazda3, Mazda6 and CX-5. We're big fans of this styling direction, so we fully expect the concept to be quite an attractive little number.
Hazumi means "bound" or "spring up" in Japanese, with Mazda saying this nomenclature is "particularly well-suited to a small car that appears to be bursting with energy." In other words, say goodbye to the friendly faced Mazda2 we've enjoyed since it launched in the United States in 2010. Instead, prepare for something decidedly more assertive, hopefully improving upon the already-great driving dynamics of the current subcompact. If we're honest, we can't wait.
Mazda will also use the Geneva show to debut its new small-displacement, 1.5-liter Skyactiv-D diesel engine. The automaker hasn't confirmed that this new fuel-efficient powerplant will be part of the Hazumi concept package, but considering the two are debuting alongside each other, it would seem to make sense. As for whether or not this engine could come stateside when the next Mazda2 launches, we're not holding our breath for that, especially considering the company's current woes with US-spec diesel engines.
