Mazda patents show rotary engine for range-extended EV

Two years ago, Mazda introduced a fascinating range-extended electric car called the Mazda2 RE Range-Extender. It took an electric Mazda2, and dropped in an itty-bitty 330cc rotary engine. It wasn't the rotary-powered sports car we had hoped for, but it seemed like a unique way to keep the quirky engine alive and kicking. But not long after the car's reveal, it seemed to disappear. Now the basic idea has resurfaced with a few modern updates in a couple of US patents. The first patent is pretty straightforward and describes a range-extended EV similar to the BMW i3. At the front is an electric motor driving the front wheels. At the back is an internal combustion engine that powers an electric generator. In the middle is a lithium-ion battery for storing and delivering electricity. It's the same set-up as that Mazda2. The second patent is for an engine start-and-stop system, but specifically for rotary engines. The system is designed to shut off a rotary engine when not needed, much as modern piston engines do. It also stops the rotor in a position that closes the intake port to ensure no fuel or exhaust emissions slip out through the intake tract. This is necessary since there are no valves in a rotary, and air and exhaust come through ports that are "opened" and "closed" by the rotor itself. The patent also describes the possibility of firing a spark plug after the fuel has been cut to eliminate any leftover fuel emissions. This system would theoretically improve a rotary engine's fuel economy and emissions significantly, which would be a boon as those are two of the rotary's major weaknesses. The rotary-engine patent also includes the same range-extended powertrain drawing as the first patent. It's there as a description of a possible application. And in such an application, where the rotary wouldn't have to run all the time, the system could take advantage of the rotary's inherent strengths. Weight can be kept low thanks to the engine's small dimensions, which should help in keeping the car sprightly and efficient. Rotaries are renowned for smoothness, too, so it shouldn't need too much refining and sound deadening, the latter of which adds more weight. The small size would also help with packaging, leaving more space for people, cargo, or possibly batteries. And since it has been patented, the company may be looking to bring the system to market.

Mazda CX-5 Luggage Test | How much cargo space?

We're already seen how Mazda's largest crossover, the CX-9, does at stuffing luggage inside its cargo hold. Now it's time for the next rung down the Mazda ladder. The Mazda CX-5 has 30.9 cubic-feet of space behind its raised back seat, which on paper, is considerably less than its top competition. The Hyundai Tucson leads the way with 38.7 cubic-feet, the Honda CR-V (39.2) and Toyota RAV4 (37.5) are basically the same, and the Subaru Forester has between 33 and 35 depending on options. However, the CX-5 does have more than the Chevrolet Equinox (29.9), Jeep Compass (27.2) and Ford Escape when its sliding back seat is in its aft-most position (33.5 when all the way forward).  Basically, this compact Mazda's cargo area is midpack, which makes it a good choice for my first luggage test of the segment. Let's see how much of the luggage in my garage fits inside. As a refresher, I use two mid-size 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). I also include my wife's fancy overnight bag just to spruce things up a bit (21L x 12W x 12D).  I started by keeping the cargo cover in place to see how much fits underneath it. The answer is the four largest bags. The two smaller ones did not. OK, now let's remove the cargo cover, which is an unusual design. Rather than a roller-type cartridge that you manually pull into place or a rigid hatchback-like unit that rises up when the liftgate goes up, the CX-5 basically combines the two. The forward bit is attached to the liftgate and unspools when opened.  To detach it, you need to unfasten these plastic clamps and then remove the cartridge reel much as you would a normal cargo cover. OK, and now here's how much the CX-5 can fit with the cargo cover removed.  All of it! That above configuration is just the first thing I came up with, but there's likely additional Tetris formations to be found. Note that the tailgate does close here but the middle cases' wheels are awfully close to the window.  I'm not going to stop there, though. I went ahead and rummaged through my garage to see what it would take to fill'er up. There you go: one duffle bag and one gym bag stuffed into the spaces. You could probably fit a grocery bag right in front there, too.

Mazda expands scope of vehicles affected by Takata airbag recall to 330k

Earlier this week a Reuters report indicated that Mazda was considering a nationwide expansion of its recall for vehicles equipped with Takata airbag inflators. The company has now confirmed said expansion, with the vehicle count jumping from 86,770 to 330,000 affected in the US. As before, the affected vehicles are Mazda6 and RX-8 cars from the 2004 to 2008 model years. Mazda reports that Takata has tested a "large number of inflators removed from Mazda vehicles" and not found any to be "non-compliant" as of yet. With that said, the company also reports in its statement that one 2005 Mazda6, located in Florida, has been identified as having had an "abnormal" deployment of the driver's side airbag. For what it's worth, though the company's statement references the Takata inflator issue as a proper recall, it is calling its own program of notification a "Safety Improvement Campaign" for the moment. Find the full, if brief, Mazda press release in the form below. UPDATED MAZDA STATEMENT REGARDING TAKATA AIRBAGS Dec 11, 2014 WASHINGTON, DC (December 11, 2014) – In addition to the actions announced on December 4, 2014, as discussed in a separate document, Mazda today announced the following steps in the Takata recall: Mazda will institute a nationwide Safety Improvement Campaign of 2004-2008 model-year Mazda6 and RX-8 models equipped with certain Takata airbag inflators. The nationwide Safety Improvement Campaign will cover the driver's-side airbag inflator, as Mazda has not made a safety defect determination at this time. This action will support us to gather additional parts for examination and to promote customer satisfaction and safety. There are approximately 330,000 vehicles included in this Safety Improvement Campaign in the United States So far, Takata has tested a large number of inflators removed from Mazda vehicles, and NONE have been found to be non-compliant at this time One vehicle – a 2005 Mazda6 located in Florida – has been identified as having experienced an abnormal driver's-side airbag deployment. Mazda has worked closely with NHTSA on this situation Mazda will participate in the independent, industry-wide joint testing program for Takata airbag inflators For history, on December 4, 2014, Mazda announced: It would expand the area of the high-temperature, high-humidity region recall to include the Gulf Coast states.
