The 2017 Honda Ridgeline's innovative bed

Today most truck makers put their emphasis on high-zoot comfy interiors, towing bragging rights, and macho styling (aka my grille's bigger than yours). The "work area," aka the "bed," for the most part, is often an afterthought. Yeah, there have been improvements, but they've come slowly; and frankly most to date have not been very innovative and/or have been poorly executed. A thinking man's truck Since the very first Ridgeline was introduced, and now with the new 2017 model, Honda has done a lot of serious thinking when it comes to the bed – how it's used, and how to make it even more user-friendly. For the most part great ideas abound, while some like the in-bed audio system seem really silly. The two-way tailgate is flat-out brilliant, even if the idea was borrowed from 1970s Detroit station wagons. Other trucks offer optional bumper steps, fold-out steps, or a tailgate step to aid bed access. Good ideas for sure, but Honda's swing-out tailgate solution is so simple and so elegant it hurts; plus it's standard. The Ridgeline's ability to lay 4x8 building material flat on the floor of the bed is a no-brainer, especially for someone who likes to do home projects; yet Honda is the only mid-size truck to offer that capability. The storage trunk in the bed is another super idea – most of the time. Is it perfect? Nope. Some say accessing the bed trunk with a load of mulch is a problem. No argument there, so you plan ahead. Same with accessing the spare tire; it could be a BIG problem with a loaded bed. Then again, how often do you see a Harry Homeowner truck with a loaded bed? The odds are, if you're going to get a flat tire, most likely the bed will be empty. If not, well then you must have angered the gods. Speaking of flat tires, Honda blew it big time here by giving the Ridgeline a temporary spare tire. no truck should ever have a temp tire; full-size spare all the way, baby! No way do I want to have to use a temp tire while carrying a load or towing a trailer. Hopefully they will offer a full-service spare as an option. The funny thing is, the previous model sold in Mexico came with a full-size spare standard. From what I've heard, the reason the American-spec model comes with a temp tire is to save weight; and Honda will do anything to save weight, to improve EPA mileage ratings, even if it's unwise for real-world conditions.

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.

NHTSA expands new Takata probe to 4 more automakers

DETROIT — The U.S. government's highway safety agency has launched an investigation into four additional automakers that have a potentially deadly type of Takata air bag inflator in their vehicles but have yet to recall them. The National Highway Traffic Safety Administration said in documents posted Thursday that it is investigating Audi, Toyota, Honda and Mitsubishi in connection with a Takata recall involving 1.4 million inflators. This brings the total number of manufacturers potentially impacted to five, as BMW was connected to the issue when it was brought to light earlier in December. The inflators made by the now-bankrupt Takata have a distinct and separate problem that can cause them to blow apart a metal canister and spew shrapnel into people's faces and bodies. The problem killed a driver in Australia who was in an older 3-Series BMW, which has already recalled more than 116,000 vehicles. The problem is so dangerous that in some cases BMW has told drivers to park their vehicles until repairs can be made. The safety agency says in documents that Takata didn't provide details on the affected makes, models or model years of vehicles with the defective inflators. So it is telling the companies to recall them promptly. The agency says that based on when the faulty inflators were produced, it's likely that the vehicles to be recalled came from the 1995 through 2000 model years. In letters to all four automakers, NHTSA says they have five business days to notify the agency after finding out about a safety defect. “If your company has not yet gathered enough evidence to make a determination that the subject air bag inflators present an unreasonable risk to motor vehicle safety, reply with a detailed work plan including the benchmark dates required to make the determination,” the agency wrote in letters to all four automakers dated Wednesday. A Honda spokesman said Thursday it hasn't determined yet whether its vehicles are affected, but a decision should be made soon. Audi, Mitsubishi and Toyota said they are still investigating. NHTSA has told the companies to respond by Jan. 17. On Dec. 4, NHTSA posted documents from Takata and BMW detailing the problems. The documents said the Australian driver was killed, while another Australian driver and a driver in Cyprus were injured. Unlike previous recalls, the Takata non-azide inflators do not use volatile ammonium nitrate to fill the air bags in a crash.
