Honda Insight finally, officially dead

Earlier this week, we told you that the Honda Insight was scheduled to get the axe - something that had been rumored for a long time. Now, Honda has officially confirmed that the Insight is being put out of our its misery. That's right, America's most affordable mass-produced hybrid will officially die after the 2014 model year, with production scheduled to end this summer. Honda says that, moving forward, it will focus its efforts on expanding its newer two-motor hybrid system found in the Accord. Of course, this news doesn't exactly give us much hope for the CR-Z hatchback's longevity, either. Scroll down for the official release.

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 has more tricks in store for next Civic Type R

While we can only admire the current Honda Civic Type R from afar, the next version is slated to make its way to American showrooms. That's not expected to happen until 2017, but our friends over at CivicX.com got a sneak peek at the engine that will provide its motivation. And it looks to be shaping up to be a real firecracker. Honda's latest 2.0-liter inline-four is slated to take its advanced design even further. Not only will it combine a turbocharger with the company's signature VTEC variable valve timing system, but closer inspection of the pictured engine reveals that it will also feature an electric actuator on the wastegate as well as a bypass valve integrated into the compressor housing. Expect the new Type R to be even faster and more potent than the current version. That's saying a lot considering that the existing Type R already packs 306 horsepower and clocked the fastest time for a front-drive car at the Nurburgring – besting the Renaults and Seats that diced it for top honors until now. It'll surely be an expensive piece of kit, though, which brings us to another potential piece of good news. This engine is tipped to make it into the lower-level Civic Si as well, albeit in a somewhat detuned state. As it is, the outgoing Civic Si packs 205 horsepower, so there's plenty of room to improve before it starts threatening even the existing Type R, let alone the more potent model to come. All of which tells us that the Si will be no slouch either, and with those features will surely prove a favorite once again in the tuner crowd. Related Video:
