1991 Acura NSX Luggage Test: Will a Motocompacto fit in the trunk?

I know I know, the wait has been killing you. From the second the Honda Motocompacto electric scooter/suitcase was introduced, you've desperately been begging the universe to answer the following question: "Will the Honda Motocompacto fit in the trunk of a 1991 Acura NSX?" Believe me, the suspense was killing me, too. Well, rest assured, your answer is finally here.  I stumbled upon old friend Tyson Hugie and his predictably pristine 1991 Acura NSX at Radwood Socal two weekends ago. While chatting about my/his old Acura TSX finding a new home with a collector in North Carolina, a gentleman on a Honda Motocompacto whizzed by and finally pulled up to a stop among the small group of people gathered around the NSX and an Integra Type R. We initially thought it had been brought by the Honda PR rep who was attending Radwood (he did in fact have one in his trunk, an Acura 2.3 CL), but it actually belonged to the person riding it. Patrick Vidal had only just got his Motocompacto the previous Monday, but had already put it to work as his last-mile transport. He says it fits behind his seat in his Toyota MR2 Spyder, as if this story couldn't get more rad. As I stood there with Tyson and Patrick chatting about life with Honda's latest creation, I started staring at the back end of Honda's finest creation. Then I looked back at the Motocompacto ... and back again at the NSX.  "Um, do you think that would fit in the NSX's trunk?" I asked, turning to Tyson. "Oh, that's happening," he quickly replied. We asked Patrick if he'd be game, and no shocker, he was. Tyson cleared out the trunk and Patrick started the process of transforming the Motocompacto from a scooter into luggage.  The transformation is certainly not a seamless process. There's lots of steps, and Patrick said that he's still getting the hang of remembering all the bits and pieces. Again, though, he'd only had the thing for five days.  Initially, I doubted the Motocompacto would fit, but as it got smaller and NSX trunk got emptier, I got a lot more confident. "OK, let's do this," said Mr. Luggage Test, rubbing his hands together.  Officially, the 1991 Acura NSX was listed as having 5 cubic-feet of trunk volume. That's actually the same as my 1998 BMW Z3's trunk, but when you're talking about such a small amount, the shape of the space really matters and in this case, the NSX trunk is basically a big rectangular cavity with a protrusion from the engine bay.  OK, let's get to the bags.

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 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.
