Highlights and standouts from the 2015 LA Auto Show

This year's LA Auto Show has been packed with interesting debuts and fascinating industry trends. The Autoblog team is on the scene to examine all the new metal, and Senior Editor Greg Migliore has some show highlights for us in the video above. In particular, the new Fiat 124 Spider and Honda Civic Coupe stand out as important debuts. The Fiat is based on the excellent Mazda Miata, with a turbocharged 1.4-liter engine and revised styling. The Civic Coupe is a striking redesign of an extremely popular and important model for the company. And the restyled Ford Escape looks more like its bigger brother, the Explorer. There's this an much more in our video above. Watch it and let us know what you think – and look for more LA Auto Show coverage coming soon.

Honda and Acura expand CPO offerings to include 10-year-old cars

With valuations having gone ballistic, buyers are spending more than ever to purchase used cars at the same time cars with 100,000 miles or more are now considered just mildly used. Effectively, the market is full of folks splashing what was new-car money not long ago on a vehicle that would have been considered all used up. Nevertheless, used car sales, especially manufacturer Certified Pre-Owned (CPO) programs, are booming. Anything that can help a shopper with peace-of-mind about what they're getting would be a boon to the process, which is why Honda and Acura have revamped their CPO program to include a wider range of used cars.  At the bottom, the new HondaTrue Used tier now accepts vehicles up to ten years old, with no mileage limit. This wasn't the case before. The entire vehicle is covered for 100 days or 5,000 miles after purchase, whichever comes first. Used buyers at this tier also benefit from common CPO perks such as roadside assistance, trip interruption reimbursement (if your new-to-you used car breaks down far from home), and one complimentary oil change within the first year or 12,000 miles. As with the other two tiers, this one offers an exchange policy for another Honda CPO vehicle within three days or 300 miles. Above that, HondaTrue Certified accepts Hondas up to five years old. The entire vehicle is covered for one year or 12,000 miles after the original new vehicle warranty expires, and the powertrain-only warranty runs for seven years from the vehicle’s model year or 100,000 miles on the odometer. This one offers a second free oil change within the first year as well. HondaTrue Certified+ is only for vehicles purchased within their new vehicle warranty coverage period — so, under four years old and with less than 48,000 miles. It provides the same powertrain coverage as HondaTrue. Acura says its CPO division has posted five straight years of growth and had a record-breaking 2021, allowing it to take over Audi's spot at #4 for luxury CPO sales. Its Acura Precision CPO now offers an Acura Precision Used tier for its vehicles up to ten years old, with no limit on miles. After purchase, each Acura Precision Used vehicle gets complete and powertrain coverages for up to six months or 7,500 miles.

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.
