Honda and Chrysler EV news, and talking with GM's charging ecosystem boss | Autoblog Podcast #781

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor, Green, John Beltz Snyder. They're excited about the news of the possibility of an electric sports car being revealed for Honda's 75th anniversary, as well as the completely revamped — redesigned and renamed — Chrysler Airflow. They've been driving the Bentley Bentayga EWB, Range Rover, Toyota GR Corolla and the refreshed Buick Encore GX. We listen to a interview Greg conducted with GM's EV charging boss, Hoss Hassani. Finally, a reader is looking to help his in-laws choose an SUV, possibly a hybrid or EV, to replace a BMX X3. Send us your questions for the Mailbag and Spend My Money at: Podcast@Autoblog.com.

Honda Civic Type R Concept to hatch in Geneva

As if the Geneva Motor Show isn't exciting enough, now we have word that a new version of a certain iconic Japanese hot hatch will make an appearance there in a few weeks time. Honda has announced that its Civic Type R Concept will be revealed during the show's media days, which take place March 4 and 5.
Since this is Honda we're talking about, we should point out that the "Concept" part of the Civic Type R's name is usually a bit of a misnomer. For the past few years, the Japanese automaker has made a habit of attaching "Concept" to the end of several near-production models in the name of drumming up auto show excitement (see Exhibits A, B, C, D and E). So really, this is almost certainly the next Civic Type R, a car we've kind of already driven.
The latter car was a "development" model, but we aren't expecting a lot to change between it and the production model. As previously reported, a 2.0-liter, turbocharged engine should deliver north of 280 horsepower to the front wheels via a six-speed gearbox. Have a look up top at the sole image of the hot Civic released by Honda, and then scroll down for the official press 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.
