Mazda CX-30 Luggage Test | How much cargo space?

The Mazda CX-30 is pretty much a lifted Mazda3 hatchback. Same platform, awfully similar dimensions, and the interior's a spitting image (if not identical). Ditto cargo capacity. On paper, the two have virtually the same amount of space behind their raised back seats, with the CX-30 at 20.2 cubic-feet and the 3 with just a teensy less at 20.1.  Now, before I go any further, let's see how much that 20.1 cubic-feet relates to in the Mazda3. I wasn't yet doing this test format back then, hence the video.  For reference, both tests used my standard luggage selection of two midsize roller suitcases that would need to be checked in at the airport (26 inches long, 16 wide, 11 deep), two roll-aboard suitcases that just barely fit in the overhead (24L x 15W x 10D), and one smaller roll-aboard that fits easily (23L x 15W x 10D). The bag of baseballs shown in the video is slightly smaller than my new small-bag go-to, my wife's fancy blue overnight bag (21L x 12W x 12D). So, the mark to beat is therefore all the bags minus the smallest roller.  Here is what 20.2 cubic feet looks like in the CX-30. To move beyond the Mazda3 comparison, that figure is in keeping with the CX-30's niche placement between subcompact (the teens) and compact SUVs (upper 20s to upper 30s). The Mazda CX-5 has 30.9 cubic-feet.  Now, typically, I start off by seeing how much I can fit inside with the cargo cover in place. Sadly, this particular CX-30's cargo cover is missing. We'll just have to hope it doesn't rob the CX-30 of as much space as the CX-5's does.  First off, it's immediately noticed that the CX-30's cargo area is not as long as the 3 hatchback's. The largest bag just barely squeezed inside, whereas there was some room to spare in the 3. Now, let's keep loading.  Whattya know? All of the roller bags fit inside. That includes the smallest one, which didn't fit in the 3, fitting atop the stack with perhaps 30% of it over the back seat line. Now, I could've done the same Tetris stack in the 3, but I'm virtually certain the hatch wouldn't have closed. Advantage, then, to the CX-30 and its extra height.  And surprise, the fancy bag also fits. Technically. It robs rear visibility, is pretty far above the seat line and it just barely fits under the back light. If it was filled, I have my doubts about its inclusion. Nevertheless, with or without it, there's still a bit more space on the right side for that bag of baseballs.  Now let's discuss the power liftgate.

Mazda G-Vectoring Control makes driving better without you knowing

Mazda has just spent eight years developing a new technology that will make its new cars a lot more fun to drive, even if you have absolutely no idea that it's working. And subtlety's the point, Mazda engineers told us at a press event at Mazda Raceway Laguna Seca. In fact, the effects of what they've dubbed G-Vectoring Control are so fine that the marketing and PR teams are at a loss for how to do their jobs with it. "The engineers have done their work," said Mazda Director of Communications Jeremy Barnes, "But how do we get the message across?" The basic premise is this: G-Vectoring activates only when the car's on-board computer reads simultaneous steering and throttle input. The data — including throttle position, steering angle, and, crucially, how quickly you're adjusting the steering angle — are then funneled through an algorithm to reduce engine torque, which transfers vehicle weight, adding more grip to the wheels that need it. The system will appear first on 2017 Mazda6 sedans arriving in showrooms later this year, followed by the 2017 Mazda3. Actually, "subtle" does not even begin to describe the effect. G-Vectoring Control can detect as much as one tenth of one degree of steering angle, and changes the cornering forces only 0.1 to 0.5 g as a result. "That's less than the human body can feel," explained Vehicle Development Engineer Dave Coleman. In practice, G-Vectoring reduces the steering angle at turn-in, as well as the rate at which one turns the wheel. To demonstrate, Director of R&D Kelvin Hiraishi rode shotgun with us in a specially equipped Mazda6 that allowed him to turn G-Vectoring on or off at the push of a button (production cars will always have it on). Hiraishi had us drive a number of courses, including Mazda Raceway Laguna Seca itself, while an engineer measured our steering inputs with a laptop Matrix'd into the car's electronic brain. I drove the same course several times with the same car in the same conditions, with cruise control locked and the system turned on or off. Lo and behold, with G-Vectoring activated, the engineer's output graph showed that my steering inputs were indeed reduced ever so slightly. There were two times that G-Vectoring was markedly noticeable. The first on a turn with a minor banking toward the outside, and the second was during cornering over an artificially wet section of the course — in other words, when the car was at the limits of adhesion.

Sorry, rotary fans, Mazda's RX Vision probably won't happen

Mazda is doing a lot of things the right way in this age of beige-ness. It just crammed a turbocharged inline-four into the improved CX-9, a bold move unto itself, and one that should also be heartening for Mazdaspeed fans. Wouldn't that engine make for a swell Mazdaspeed3 or Mazdaspeed6? There's a reasonable ray of hope there, but not necessarily a guarantee. The RX Vision, though, is a pipe dream. Mazda is smart to keep the rotary dream alive. It's smart to keep developing it in back rooms and to keep the idea on the public's mind. Credit where credit's due: Mazda has solved some of the stickiest issues the rotary engine has, through savvy engineering and perseverance. We've seen promising patent filings for the Skyactiv-R engine, which is supposed to be found in the RX Vision concept. Mazda uses every opportunity to remind us that development is continuing and that the company would love to bring a rotary-powered sportscar to production. I believe it. But the RX Vision is just a design study. And there are some harsh realities about rotary engine emissions and fuel economy standards that are difficult for modern piston engines to achieve without expensive componentry. Emissions and fuel economy are both bugbears of the rotary, in case you've forgotten. And that explains Mazda's interest in running rotaries on hydrogen, but down that road lie infrastructure challenges as daunting as making a gasoline-powered rotary burn as clean as one of Mazda's Skyactiv piston engines. All this is meant to put Mazda's recent comments to Top Gear in context. Mazda's design director, Kevin Rice, spoke to TG at the Concorso d'Eleganza Villa D'Este, and was waving Mazda's rotary flag quite enthusiastically. "In the back rooms at Mazda, we're still developing it," Rice said, "and when the world's ready to buy another rotary, we'll be ready to provide it." I'd like that to be a comforting statement, but given the realities of fuel economy and emissions regulations and Mazda's position in the market, it seems like a hollow platitude. "When the world's ready" is just another way of saying "when we solve the fundamental issues with this engine layout, and there's an unambiguous market study that shows we can build these cars and make a profit, we'll consider it." That seems like a lot of "ifs". Perhaps Mazda does have a clean-burning, efficient, cheap-to-produce rotary running on an engine dyno in Hiroshima, and it's prepping an RX-9 for the next auto show.
