Honda Ridgeline, Ford Ecosport and Tesla profits | Autoblog Podcast #537

On this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Green Editor John Beltz Snyder and Associate Editor Joel Stocksdale. We talk about driving the 2018 Ford Ecosport and Hyundai Accent. Joel tells us why he loves the naturally aspirated engine in our long-term Honda Ridgeline. We discuss Tesla's profitability claims, Johan de Nysschen leaving Cadillac and a possible date change for the Detroit Auto Show. As usual, we'll also spend a listener's money on a car.

Listen, the Type R and the WRX STI don't look alike. Here's why.

So following the reveal of the new Honda Civic Type R, we've seen quite a few commenters issuing all kinds of accusations about the Type R looking like a WRX STI. And you know what? They're right. Both cars have four wheels, four-passenger doors, big wings, and scoops. In all seriousness, aside from a passing similarity because they're both flashy sport compacts, they really don't look alike. Let's start with the front and the profile. These areas are technically the most similar, since both cars feature high beltlines and have lower fascias defined by large inlets and a deep chin spoiler. And admittedly, the little kick-ups on the lower rear portion of the side windows are reminiscent of each other. But that's where the similarities end. Up front, the grille is by far the clearest indicator that the Honda is most certainly a Honda. The wide "blade" shape that spans the nose from light-to-light is unmistakably from the company that gave us VTEC. After all, just about every Honda today uses some form of that grille. The Subaru, on the other hand, has a traditional grille that is distinctly separated from the lights. It's not a bad thing, Subarus have had rather anonymous designs in the past, and we've still liked them. It's a Subaru thing. Moving to the scoops, we find more differences. For once, the Type R is more restrained, with a small, low-profile inlet far back on the hood. It will not be mistaken for the massive one on the STI, which looks like it could suck up low-flying fowl. View 58 Photos Along the side, the distinctions continue to pile up. The key here is in the fenders. While the STI has proud, pumped-up fenders compared with its distant Impreza cousin, they aren't nearly as pronounced as those on the Type R. The Honda's flares clearly show that they protrude from the standard hatchback's sheetmetal and closely follow the curve of the wheelarches. The STI's fenders proceed along the body's lines more closely and blend in more. Finally, we come to the rear, where no one should ever get these two vehicles confused. Yes, they both have enormous rear wings and diffusers, but that's it. For starters, one car is a hatchback, and the other is a traditional sedan. Not only that, but the Type R's hatch has a distinctive split rear window. I mean, based on the criteria people have used to compare the Type R with the STI, they should've actually been comparing the Honda to a Prius.

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.
