2019 Toyota Corolla vs. compact hatchbacks: How they compare

So you've read what we thought about the 2019 Toyota Corolla Hatchback. Oh, you didn't? Well, click to your left, we'll still be here. Just made some coffee, we're good for a while. Welcome back! Wasn't that riveting? The blue paint sure is bright, eh? Well, now you must be wondering how that new 2019 Corolla stacks up with all the other hatchbacks. And, despite long thinking that hatchbacks were doomed, there are actually quite a lot of them these days. So many, in fact, that we couldn't fit them all in our space-limited comparison chart. So, with apologies to the Hyundai Elantra GT, Kia Forte and the dead-man-walking Ford Focus, these were the cars we chose based on sales and competitiveness: the Honda Civic Hatchback, Mazda3 5-Door, Volkswagen Golf, Chevrolet Cruze and Subaru Impreza. We also included the outgoing Corolla iM for reference. If you think we've left something of interest out, you can always create your own comparison. Performance and fuel economy There is but one king here, and its name is Civic. While the sedan and coupe come with a naturally aspirated 2.0-liter 158-horsepower four-cylinder that's less potent than the Corolla's, the hatchback comes standard with the 1.5-liter turbo that aces the segment in terms of both acceleration and fuel economy. The Golf's acceleration should be comparable, but as you can see, it trails on fuel economy (still not bad, though). The new Corolla ends up being better than the rest with its new 168-hp four-cylinder paired to novel transmissions: a six-speed manual with rev-matched downshifting (!) and a CVT that mimics the actions of a 10-speed automatic. The Corolla does weigh more than everything else, though, so that could hamper its acceleration. Fuel economy data also wasn't announced, but Toyota indicated it would be a bit better than the old Corolla iM. Something akin to the 2.0-liter Mazda 3's numbers seems likely. As for the Mazda, its top two trim levels actually come standard with its bigger engine. In any event, despite its ample power, testing has often showed that the Civic is still the quicker car from 0 to 60 mph. And finally, let's not leave out the two on the end. The Subaru is the only car in the segment that offers all-wheel drive (the Focus RS and Golf R don't count), but is also the segment weakling now that the Corolla iM has been discontinued.

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.

Acura replaces chief Accavitti with designer Ikeda

Acura is shaking up its senior leadership, as Honda ushers the current chief of its luxury division out the door and replaces him with a new one. Exiting stage left is Mike Accavitti, who held the reins at the premium automaker as its senior vice president and general manager of the Acura division. Taking his place will be Jon Ikeda, one of the Japanese automaker's most senior designers. Accavitti (pictured above at left) had been promoted to the job from his previous position as senior vice president of auto operations after Honda separated the Acura brand into its own division. He had previously served as a senior executive at Chrysler, rising up the ranks to run the Dodge brand, and joined Honda in 2011 as its chief marketing officer. At this point it remains unclear why Accavitti is leaving and where he might land, but Honda says he's leaving the company altogether. To replace Accavitti, Honda has named Jon Ikeda (pictured above at right), a veteran designer with the company. A graduate of the Art Center College of Design in Pasadena, CA, Ikeda has worked for Honda on both sides of the Pacific since 1989. He previous headed up the design and product planning divisions at Honda's American R&D operations, and was instrumental in creating an independent design office for the Acura brand, separate from Honda's. This isn't the first time we've seen Accavitti replaced in his role as a senior executive by a design veteran. After only four months at CEO of the Dodge brand, he was replaced by Ralph Gilles, who retained his role as senior vice president of design for the entire Chrysler group in parallel. Gilles was ultimately replaced as head of Dodge as well, but was recently promoted to serve as head of design for Fiat Chrysler Automobiles.

July 27, 2015 – Acura today announced that Jon Ikeda has been promoted to Vice President and General Manager of the Acura Division of American Honda Motor Co., Inc. In this role, Ikeda will oversee all Acura brand activities including sales, marketing and parts and service. Ikeda was formerly Division Director of Auto Design at Honda R&D Americas, Inc. (HRA). He began his career at Honda in Japan in 1989, joining the advanced design studio in Tokyo, where he worked on the award-winning Honda FSX show car. After six years in Japan, he returned to Los Angeles in 1995, to continue his career at Honda R&D in Torrance, California.
