2020 Mazda CX-30 First Drive | The middle way

JULIAN, Calif. — An Aveo wanders in the lane ahead, its gas flap open and waving in the 30-mph slipstream as it creeps along some of the best roads in all of Southern California as swiftly as a retreating glacier. The 2020 Mazda CX-30Â’s speedometer needle quivers and then falls. The longing for a passing zone becomes unbearable. Even with a merely adequate 186 horsepower and a standard automatic, I canÂ’t wait to smoke this Aveo as I arc into another corner, tap brakes to transfer weight, and scoot into the next. And then a sort of calm washes over, provoking the slightest smile. The smile is a realization that, short of a few performance models from the German brands, most compact crossovers donÂ’t beg for this sort of action. The CX-30 is not most crossovers – itÂ’s built on the bones of the dynamically overachieving Mazda3, making it legitimately rewarding to drive. Think of it more as a car that happens to be marketed as a crossover. The careful attention to vehicle dynamics means it doesnÂ’t wallow like you might expect a jacked-up 3 might. What it feels like is a 3 variant, not an entirely different vehicle — analogous to the Subaru CrosstrekÂ’s relationship to the Impreza, albeit with greater visual differentiation and a much more sophisticated driving experience. ThatÂ’s a very, very good thing indeed – and letÂ’s take a moment to review the virtues of the 3 to explain why. ThereÂ’s nothing in its class that nails its brief so well. The interior looks exceptionally premium in higher trim grades, it drives better than anything in its class, and the sheetmetal “oozes sex appeal,” as contributing writer Jason Cammisa put it – although less oozing is present in the awkward hatchback. ItÂ’s even available with all-wheel drive. However, I respectfully disagree that the engine is refined – the Skyactiv-G 2.5-liter inline-four, a carryover from the last generation and shared between the 3 and CX-30, is harsh and clattery. In both vehicles it gets the job done. That 186 hp is backed up with 186 pound-feet of torque, channeled exclusively through a six-speed automatic in the CX-30. Front- or all-wheel drive is available in every CX-30 trim. And while thereÂ’s roughly a 200-lb weight penalty over the 3, the CX-30 manages to feel perky, not porky. Nor is the fuel economy hit as much as you might imagine.

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.
