2020 Toyota Highlander vs other 3-row crossovers: There can only be one!

We've done quite a few spec comparison posts involving three-row family crossovers, and when included, the Toyota Highlander has always been the runt of the group. While the rest increasingly seemed to be benchmarking each other toward greater girth, the Highlander was the outlier.  That changes a bit for the 2020 Toyota Highlander, but only a bit. It's now larger and more competitive, specifically in regards to the amount of cargo space aft of the third-row seat. As you can see below, this aligns the Highlander most closely to its long-time competitor the 2020 Honda Pilot. However, let's see how it stacks up to others in the segment, which is heavily populated now, so for the sake of space, we've selected the newest entries: Kia Telluride, Hyundai Palisade, Subaru Ascent and Ford Explorer. The order in which they are presented is random.  Performance and fuel economy The 2020 Highlander is more than 200 pounds lighter than its predecessor, but has the same 295-horsepower V6 engine that was already one of the strongest in the segment. We'd say that would give it a leg up, but the Pilot and Explorer have proven to be sprinters, delivering 0-60 times in the low-6 range by some publications' stopwatches (or VBoxes, whatever). We don't expect the Highlander to beat them, but it may dip into the 6's. The heavy, less-powerful Subaru Ascent is most likely to take up the rear. It's fuel economy of 23 mpg combined also matches the Highlander and Explorer for segment-best. Remember, however, that the Explorer's turbocharged inline-four engine is likely more susceptible to differences in driving style (read: a heavy foot).  Of course, if you're really interested in fuel economy, the Highlander and Explorer are the only vehicles in the segment to offer hybrid versions. The Ford Explorer Hybrid puts a greater emphasis on performance, however, resulting in lower estimates of 25 mpg combined (AWD) and 28 mpg combined (FWD). By contrast, the new 2020 Toyota Highlander Hybrid is estimated to return 36 mpg combined.  Passenger and cargo space According to Highlander chief engineer Yoshikazu Saeki, he had a choice of two directions with the new Highlander. He could have indeed made it bigger, matching these very competitors, especially in terms of third-row and cargo space. Or, he could have maintained a smaller-than-average size. He obviously chose the latter. First, it was the size customers had come to expect. Would they be put off by something bigger?

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.

Red Bull F1 denied access to Honda engines

There are four engine manufacturers in Formula 1: Ferrari, Honda, Mercedes-Benz, and Renault. Infiniti Red Bull Racing ended its marriage to Renault, got to the altar with Mercedes and then Mercedes backed out, couldn't even agree on a pre-nup with Ferrari, and Honda flat-out said, "No." At the moment that has left the four-time World Champions without an engine for next year, owner Dieter Mateschitz threatening to take his two teams and four cars out of the sport, and F1 honcho Bernie Ecclestone threatening to sue Mateschitz if he does. The Japanese company had turned down the idea because after a first year with some poor performances and a few public sour notes, it wants to get McLaren's cars running properly before it expands its operation. Now it seems some behind-the-scenes action of late has opened up channels between Red Bull and Honda, and the two are at least talking. Honda, though, still says such a deal is highly unlikely at best, and Red Bull says it will have something to say when something is done. It appears that McLaren chief Ron Dennis, however, has vetoed the idea. Ecclestone says Honda made a deal with the FIA that would allow Honda to supply two teams in its second year, but Honda gave Dennis veto rights over who the second team would be. For the same reason that Mercedes backed out and Ferrari only wanted to sell Red Bull year-old engines, Ecclestone says Dennis might view Red Bull as a competitor and doesn't want to risk two more cars getting in front of his own. If that's the case and Red Bull is going to remain in the sport, it might need to hit the flower shop and book a trip to Renault headquarters. Soon. Related Video:
