Honda issues 'do not drive' order for older cars with recalled Takata airbags

Honda and Acura instructed owners of more than 8,000 cars built from 2001-2003 to park them until they can have their Takata airbags replaced as part of the ongoing global campaign to eliminate millions of deadly inflators. Honda says the "Alpha" generation Takata inflators can fail at rates as high as 50%, causing potentially fatal injuries from flying shrapnel in the event of a collision.  Honda and Acura models with the "Alpha" generation Takata airbags include:  2001-2002 Honda Accord  2001-2002 Honda Civic  2002 Honda CR-V  2002 Honda Odyssey  2003 Honda Pilot  2002-2003 Acura 3.2 TL  2003 Acura 3.2CL "Approximately 8,200 Honda and Acura vehicles with the most dangerous airbags are still being driven today. Honda has replaced or accounted for more than 99% of Alpha inflators, but it is absolutely critical that these remaining vehicle owners act now to protect themselves and their loved ones," Honda's announcement said. "These vehicles are 20 to 22 years old now, and the risk to vehicle occupants is dire. Alpha air bags are some of the oldest under recall, and they have a 50% failure rate. If the inflators rupture, the metal fragments ejected toward the driver’s face could kill or leave them with devastating, life-altering injuries." Honda and Acura are far from the only brands whose models were built with defective inflators. A campaign has been underway for the better part of a decade to replace millions of the devices worldwide as drivers continue to die from injuries caused by exploding inflators.  All such repairs are free of charge to customers. Acura/Honda Customer Service can be reached at 888-234-2138 or by visiting their Takata website.   Recalls Acura Honda Ownership Safety Takata airbag recall

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.

2014 Honda Grom motorcycle is a 125cc-shot of awesome [w/video]

My very first turn at the handlebars of a motorcycle came courtesy of an MSF Honda CB125. Despite the fact that it wore a very stern sticker on the tank warning all who rode that it was for instructional purposes only and not for legal sale, I wanted nothing more than to ride it past the cones of my license test and straight home. There was just something about the lightweight, low-power machine that just felt right. Now Honda is giving American buyers the chance to take home something similar. Meet the Grom. Yes, it's basically a sexed-up scooter, but that's fine by me.
There's a fuel-injected 125cc single pushing the fat-tired bike around, and a four-speed gearbox handles shifting duty.The smallish 12-inch wheels give the Grom a bit of a goofball appearance, but the handsome bodywork and gold forks help offset the look. Something tells me this joker is more fun than should be legal. Check out a fun video of the bike in action by scrolling down, and while you're there, you'll find a full press release on all of the new Honda powersports models, including the Grom. You can also head over to the Honda consumer site for more information. The bike will land in showrooms this August with an MSRP of $2,999.
