Who can really claim first mass-produced fuel cell vehicle delivery in US?

Last month, Hyundai said that the initial deliveries of the Tucson Fuel Cell vehicles in California meant that, "For the first time, retail consumers can now put a mass-produced, federally-certified hydrogen fuel cell vehicle in their driveways." But try telling that to Jon Spallino. In 2005, Honda leased a hydrogen fuel cell FCX, a small hatchback, to the Spallino family (as far as we know, he parked it in his driveway). The company did the same thing again in 2008 with the FCX Clarity, a sleek new design based on the FCX Concept, and others signed for the H2 ride as well, including celebrities. No matter how you slice it, Honda has been in the fuel cell delivery market for almost a decade now. Just look at this. Or this. Or this. Oh, and other automakers (General Motors in Project Driveway in 2006 and Mercdes-Benz with the F-Cell in 2010, for example) have delivered fuel cell vehicles in the US as part of short-term test programs. But let's get back to Hyundai's claim. There's little question that the first delivery of a "fuel cell vehicle for the US market" has already taken place (and they were federally certified, too), which means that the debate revolves around the definition of mass-produced and whether "mass production" is about a number or about the process? Let's investigate below. First, lets review Honda's bona fides. We can start with the official version of Honda's fuel cell history, which is missing the pertinent detail that Honda build the Clarity on a dedicated assembly line and established a small network of three dealerships to lease the FCX Clarity in 2008. All of the FCX Clarity vehicles in customer hands in the US were leased through these dealerships. Sure, Honda started with hand-built stacks in its hydrogen vehicles, but went to automated control of some parts and components with series production. "It is good to see others doing today what we've been doing since 2008" – Steve Ellis, Honda Or, as Honda's Steve Elllis put it to AutoblogGreen regarding Hyundai's fuel cell deliveries: "This was exactly as prescribed by the creation of the California Fuel Cell Partnership. It's the very essence of 'co-op-itition.' We at Honda, as do many others, continue to push forward on many technologies, both the battery and the fuel cell. And society is the beneficiary." Then he added, "It is good to see others doing today what we've been doing since 2008." Now, how does Hyundai compare?

'Butching up' the 2017 Honda Ridgeline

Honda has announced a number accessories for the Ridgeline at the Chicago Auto Show: black roof rails, cross bars, running boards, and fender flares; a skid plate; a hard tonneau cover; special 18-inch wheels with all-terrain tires; and a towing kit. Most of these items are to be expected, while a few others raise an eyebrow. It appears that Honda is testing the waters to see if there is an audience for a "butched up" Ridgeline. The skid plate, fender flares, and all-terrain tires all move it a step in that direction visually. I'm not absolutely certain, but I don't think these accessories, which have a slight nod towards off-roading, have been offered by Honda in the past. Perhaps an informed reader can clarify that? There's been no word yet as to whether the tire size is larger, but looking at the image, it appears the tire may have a slightly taller sidewall. I believe the factory 18-inch tire offered is a 265/60, so this may be a 265/65 tire. Again, someone at the Chicago show could clarify this. As tepid as this may seem, it's a start. That's the good news. If these items prove successful, they may just push Honda enough to offer a beefed up trim level. Fingers crossed. This concludes my series of Ridgeline reports. I'm hoping to be at the New York Auto Show in March, and the Ridgeline is on my list of vehicles to crawl all over. If I learn of anything new, you can be assured I will report it here.

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.
