2014 Honda Odyssey set to clean up in NY with world's first in-car vacuum

Much of the minivan segment's volume has been sucked up by the industry's ever-increasing appetite for crossovers, but a few major players are hanging in there, eager to serve as beasts of burden for America's families. Chief among those players is Honda, which is showing its revamped 2014 Odyssey at this week's New York Auto Show with a potential game-changing feature - an in-car vacuum.
Co-developed with Shop-Vac, the HondaVAC system will come standard on the range-topping Touring Elite model. The system includes a replaceable filter and canister bag, along with a range of attachments located in the cargo hold. Honda says this first-ever feature includes a hose that is long enough to clean the entire interior. Better still, the vacuum will run for up to eight minutes after the vehicle is turned off, so you can get every last Cheerio out of the seat cushions, and it never needs plugging in or recharging, as it runs off of the vehicle's electrical system.
In other news, the 2014 Odyssey gets a new aluminum hood and fenders to pair with its revamped grille and lower fascia. Headlamps get a more sinister look thanks to darker surrounds, and there are new LED taillamps out back, as well as revamped side mirrors on the doors. Underneath the skin, Honda says the 2014 Odyssey has received structural changes to help it ace the Insurance Institute For Highway Safety's new small-overlap frontal crash test, and it's also added active safety features like lane departure warning and forward collision warning to the optional features list.

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.

Takata airbags were adopted in late 1990s to save a few dollars per vehicle

According to a new report from The New York Times, General Motors started using airbags supplied by Takata in the late 1990s as a cost-saving measure even after receiving warnings about their safety. Takata's airbag modules were reportedly 30-percent cheaper than its competitors' offerings. GM approached Autoliv, which until that time had been its main airbag supplier, to see if it could offer a competitively priced alternative to Takata. Autoliv tested Takata's airbag inflator and found that it was unsafe, according to scientists who worked for the supplier at the time. Chris Hock, who until recently still worked for Autoliv, said the inflator "turned it into shrapnel" when tested. GM was subsequently warned by Autoliv that Takata's ammonium nitrate inflators were potentially dangerous. Still, "General Motors told us they were going to buy Takata's inflaters unless we could make a cheaper one," said Linda Rink, who served as a senior scientist at Autoliv at the time. A spokesperson for General Motors told The Times that it would be inappropriate to comment on discussions that "occurred two decades ago between Old GM and a supplier." So far, no Takata-supplied airbags have ruptured in an accident, and GM was far from the only automaker to make a switch to Takata airbags in order to save money. A total of 64 million airbags have so far been recalled from nearly every automaker selling vehicles in America. A spokesperson from Honda said in a statement to The Times that "There was no industry understanding in the late 1990s" that ammonium nitrate airbag inflators were risky. The majority of deaths linked to Takata airbags were in vehicles built by Honda. Takata still produces airbag inflators that use an ammonium nitrate compound, despite the devices being blamed for at least 14 deaths. Click here for NHTSA's dedicated site on open Takata recalls.
