2017 Honda Accord Hybrid launches with best-in-class fuel economy

After a one-year hiatus, the Accord Hybrid is back. Billed as a 2017 model, it goes on sale this spring. Honda has not detailed pricing for the new version, but American Honda Executive Vice President John Mendel says it will be similar to the 2015 model. The big items are 212 horsepower, an increase of 16, and EPA fuel economy ratings of 49 city, 47 highway, and 48 combined miles per gallon. All of those numbers are class-leading for midsize hybrid sedans. On paper the city figure is lower than the previous Accord Hybrid, rated at 50 mpg, but there's a reason. In 2017 the EPA is revising the fuel economy numbers downward to bring them more in line with real-world results. A similar adjustment happened in 2008. The new Accord Hybrid is certified for 2017, while competitors like the Chevrolet Malibu (47 city/46 hwy/46 combined) and Toyota Camry (43/31/39) use the current rules. Honda says the improvement is about four percent, so if the new car carried a 2016 sticker, the highway figure would be as high as 52 mpg. View 19 Photos Honda's reveal is light on other details about the new Accord Hybrid. The company stated only that the fuel economy gains come from a total re-engineering of the powertrain that includes new electric motors and a revised 2.0-liter Atkinson-cyline gasonline engine. A lithium-ion battery pack in the trunk eats up about two cubic feet of cargo space. The physical layout of the hybrid drive is the same as in the previous Accord, with two motors and a single-speed transmission for the gas engine. An explanation of the three drive modes is below. Honda engineers clarified that while the generator motor near the engine usually charges the battery it will also assist the drive motor in sending power to the front wheels at high speeds or loads.

Honda Sensing, the brand's name for its suite of autonomous and electronic safety system, is standard in the Accord Hybrid. That includes lane-keeping assist, adaptive cruise control, autonomous emergency braking, and blind-spot warning. You can't tell that the Accord Hybrid has an aluminum hood by looking, but sharp eyes will pick up the unique wheel and blue accents to the headlights and taillights. Otherwise the 2017 Accord Hybrid looks and feel exactly like a conventional Accord, save for the "EV Mode" button on the right side of the center console.

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.

Honda releases H2O brand bottled water to promote FCX Clarity

Remember when Hollywood stars Diane Kruger (Inglourious Basterds) and Joshua Jackson (Fringe) took a Mercedes-Benz B-Class F-Cell into Death Valley and "survived" by drinking water from the car's tailpipe? Honda has taken that idea into movie theaters in Australia. The idea, but not fuel cell water itself. Honda has created a bottled water brande called H2O, and it's meant to promote the hydrogen-powered Honda FCX Clarity as part of Honda's "clever thinking" campaign. The headline message, just as it was for Mercedes, is that a hydrogen fuel cell car emits nothing but water vapor, which is actually safe to drink. To give movie fans a hands-on experience, Honda Australia filled a number of Palace Cinemas movie theaters with free disposable bottles of H2O water. Of course, since there are only a handful of FCX Clarity vehicles in the world today and it would take a lot of driving to fill up that many bottles, Honda admits that, "if you're holding a bottle of our specially produced H2O water in your hand right now, you've been drinking plain old spring water. If you want to taste the real thing, you'll have to travel to California, Japan or the UK where the FCX is currently available." Of course, why anyone would want to associate themselves with the unending waste that is bottle water, a product that has not proven itself to be any better than good tap water, is beyond us. But that's what Honda is doing, as you can see in the promotional video about the stunt below. This content is hosted by a third party. To view it, please update your privacy preferences.
