Mazda CX-9 Luggage Test | How much fits behind the third row?

We recently tested the luggage-carrying capability of one of the most spacious three-row crossovers, the Hyundai Palisade, and now it's time for one of the smallest. The Mazda CX-9 may look terrific and drive even better, but that zest comes at the expense of cargo capacity, as we're about to see. The big culprit is that rakish liftgate, which not only robs the CX-9 of luggage space, but third-row headroom as well. It's pretty dungeon-like back there despite competitive legroom, and there aren't any air vents or USB ports, either. But this is about cargo capacity, so let's see how much luggage will fit inside. According to the specs, the CX-9 has 38.2 cubic-feet with the third-row lowered. That's far less than the Palisade's 45.8 and Honda Pilot's 46.8. It's actually even less than the five-passenger Honda Passport (50.5).  The test car came with a $100 cargo mat, which is velcroed to the seats and folds OK with it, but the carpet also takes up some extra space ... and the CX-9 needs as much as it can get.  To raise the seats, lean inside and pull up/back on those two handles. There is 14.4 cubic-feet of space behind the raised third row. On paper, that is indeed one of the smaller amounts in the segment, but in practice, it seems even smaller.  You can free up space by removing the rigid floor panel. If you need to carry multiple pieces of luggage, it's almost a necessity.  OK, so I have two midsize roller suitcases, both of which would need to be checked. Then there's two larger carry-on roll-aboards and one smaller one. As a bonus, there's my wife's quasi-fancy weekend bag. It was a struggle to fit three of them aboard, and Tetrised together two formations. The first uses all three carry-on bags with the cargo floor removed. And no, the fancy bag won't fit atop the blue one because it'll run into the liftgate window. A smaller tote would definitely fit, however.  This is how I could fit one of the bigger check-in bags. The liftgate just barely closed. Again, you could fit a small tote atop the blue bag, plus some other items in the lower outboard regions.  OK, so how could you fit everything aboard? Lowering half of the 50/50-split third row is a must, obviously. Both big check-in bags then stack atop each other, and then stack the other four atop each other with the cargo floor in place.

Mazda's next-gen SkyActiv engines will drop spark plugs in favor of high compression

Homogeneous charge compression ignition, or HCCI, is the black art of internal combustion engines that aims to produce diesel-like fuel efficiency for the cost of gasoline. Although some of its competitors have developed and subsequently given up on the tech, Mazda confirmed that the next-generation of SkyActiv engines will employ HCCI technology, improving fuel economy by 30 percent and at the same time reducing exhaust emissions. According to Nikkei, a new SkyActiv family of engines is set to debut under the hood of the next-gen Mazda3 sometime in 2018 before making its way into other vehicles. In simple terms, an engine that uses HCCI burns the air/fuel mix using pressure instead of with spark plugs, just like a diesel. At 14:1, Mazda's gasoline engines already have some of the highest compression ratios out there, but a move to HCCI means cranking up the compression to 18:1. While the tech sounds relatively straightforward, using HCCI means dealing with a number of side issues. It's one of those "on paper" ideas that compounds problems when put into practice. Heat, revs, and fuel must all be carefully managed as gasoline doesn't burn the same way as diesel. Mazda is mum on details, but the automaker seems confident that the issues have been sorted. If the new engines do indeed make it to market with HCCI, Mazda will have out-engineered GM, Daimler, and Hyundai, all of which have tried and failed to develop HCCI engines in a cost-effective package. With the market moving towards electrification, it's interesting to see Mazda still focusing so heavily on traditional internal combustion gasoline engines. It's an indication of where they see the market heading for the next few years. Although the automaker has been hesitant to move forward with hybrid and electric powertrains, Nikkei also reports that Mazda will begin mass production of EVs in 2019. Related Video:

Mazda MX-5 breeds upgraded Roadster RS in Japan

Fans of the new Mazda MX-5 Miata looking for something a little more performance-focused may be enticed by the new RS model. Unfortunately they'll have to go all the way to Japan to get it. Because Mazda will only be offering this particular version back home. The new RS version of the Mazda Roadster (as it's known in Japan) features a number of performance upgrades, although none of them specifically affect the engine or its output. The Roadster RS features Bilstein dampers and front suspension tower brace for better handling, along with bigger brakes for added stopping power, a retuned steering rack for sharper turn-in, and upgraded exhaust for a better sound. Inside it's also been treated to heated Recaro seats with Nappa leather and Alcantara trim and a nine-speaker Bose audio system. It also comes equipped with adaptive front lighting and high-beam control as well as lane-departure and blind-spot warning systems. Feeling left out yet? Don't be too disappointed, or book that ticket to Tokyo's Natita International Airport just yet. The Mazda Roadster RS only comes with the smaller 1.5-liter engine that produces 129 horsepower, which is significantly less than the 2.0L we get here at 155 hp. It does, however, come with the six-speed manual instead of the automatic. So while this may not be the most powerful version of the Miata, it may be the enthusiast favorite – at least in the JDM.
