Honda trademarks 'CDX' nameplate

Less than two weeks ago, we discussed the possibility of an Acura-badged version of the sure-to-be popular Honda HR-V. Now, Acura has gone ahead and registered a new trademark that fits in perfectly with its two other crossovers, the RDX and MDX. Our friends at Auto Guide report the company has reserved the name "CDX" with the US Patent and Trademark Office, with the trademark covering "automobiles and their structural parts." While it's true that these kinds of trademarks are filed regularly, the timing in this case is indicative of something more than simply covering bases. After all, it seems very, very unlikely that we'd have comments from Acura on a premium version of the HR-V on February 5 and a trademark filing for a name that fits the brand's CUV nomenclature less than two weeks later, only for it to not go ahead and build an actual vehicle. Adding to that logic is the simple fact that the compact CUV market, both on the premium and mainstream level, is arguably the hottest in the auto industry right now, and it seems like a virtual guarantee that we'll see an HR-V wearing the Acura CDX name in the not-so-distant future. Should that come to pass, look for the CDX to challenge the near-premium Buick Encore, as well as a potential compact CUV from Infiniti.

Honda patents engine with different cylinder displacements

A basic rule of engine design states that the displacement of a cylinder is equal to the engine's total displacement divided by its cylinder count. Honda, according to a recently surfaced Japanese patent, is looking to break that rule with an engine containing cylinders of different sizes. We've done our best to translate it from patent-ese. The idea is that different-sized combustion chambers give more flexibility when any combination of cylinders are deactivated, or rested. Because the different numbers can be combined in various ways, it provides more and smaller increments than would an engine with equal-displacement cylinders. Take a 2.0-liter four-cylinder, for example. Following the golden displacement rule, each of the four cylinders has a volume of 500 cc, giving displacement increments of 500 cc when any cylinder is deactivated. But suppose instead that the four cylinders displace 300, 425, 600, and 675 cc, respectively. This would give the engine 15 available displacements instead of just four, and the spacing between each option would be far less than 500cc. As a result, those different virtual displacements would provide more adjustment between power and efficiency than a cylinder-deactivation system can on a conventional engine. Honda's patent describes cylinders with equal bore size, with the displacement from cylinder to cylinder varying based on the crank throw radius – the longer the throw, the longer the stroke and the larger the displacement of that particular combustion chamber. The patent describes how the cylinder sizes would need to be arranged to spread the load on the crankshaft and presumably limit vibration that would be introduced by the different pulse magnitudes. If we're interpreting things correctly, the largest cylinder (the one with the longest crank throw radius) sits in the middle of the bank with the smaller ones alternating on either side as they decrease in displacement. This concept is described for multi-cylinder inline and V-type engines of various sizes. The patent was filed in March of 2014 and published in January of this year. Whether or not this arrangement will reach production is of course unknown, but the advantages in terms of both efficiency and power seem promising.

2018 Honda Odyssey bests Pacifica, Sienna in minivan crash, LATCH tests

Honda has a lot to be proud of following the latest round of passenger small-overlap crash testing by the IIHS. The safety organization tested the 2018 Honda Odyssey, 2018 Chrysler Pacifica and 2018 Toyota Sienna, and the Odyssey managed the best rating of "Good." The Pacifica followed behind with an "Acceptable" rating, and the Sienna brought up the rear with just a "Marginal." Both the Pacifica and Sienna lost points because the structure around the passengers collapsed to differing extents, leading to parts of the structure intruding into the passenger compartment. The Pacifica didn't intrude enough to harm passengers, with each injury area still having a Good rating, but the Sienna's structure intruded far enough to potentially harm the leg and foot areas, leading to an Acceptable rating in those specific areas. In addition to the small overlap crash test, the IIHS evaluated all three minivans for LATCH child seat anchor ease of use. Once again, the Odyssey aced the test with a Good+ rating, which is awarded for both ease of use and offering multiple anchor point options. The Pacifica and Sienna swap the crash test ratings, with a Marginal for the Chrysler and an Acceptable for the Sienna. The Odyssey and Pacifica can both brag that they're Top Safety Picks, and they'd get Top Safety Pick+ awards if they weren't hampered by headlights that only get Acceptable ratings. The Toyota Sienna fails to earn the regular Top Safety Pick award because both small overlap tests yielded results that were too low. Only one other minivan tested by IIHS has the Top Safety Pick rating, and that's the Kia Sedona. It earns an Acceptable rating in LATCH usability, and its headlights actually earned a Good rating. It hasn't undergone passenger-side small overlap crash testing yet. If it fares well, it could get bumped up to a Top Safety Pick+ rating.
