Car Forum / Honda Cars / April 2006Horsepower cuts embarass Asians
Is that new Honda or Toyota less powerful than last years model? Well, yes, and no. The engines in the new models don't make any less power than last year's engines, even though the numbers on the specification page are lower. Its just that the Asians have been caught playing the loopholes in the standards, putting in premium gas for horsepower testing while rating annual fuel cost based on regular, tweaking engine controls to non-standard settings, and turning off accessories. http://www.detroitnews.com/apps/pbcs.dll/article?AID=/20060313/AUTO01/603130350 Despite the blatant deception, analysts don't expect the kind of backlash against Honda and Toyota that plagued Hyundai several years ago. After being caught redhanded overstating horsepower, Hyundai paid cash compensation to over 800,000 owners. "Honda and Toyota owners aren't like that", said Joseph Camel of the Brand Research Institute. "They're pretty docile owner groups. After all, they bought the idea that its normal maintenance to automatically replace water pumps at 75,000 miles. Meanwhile, Honda is proposing a new "Effective Horsepower" rating system. "We intended our horsepower ratings to simulate effective horsepower when the vehicles are five years old. Our vehicles lose an average of 46 pounds by that age, meaning better performance" said Honda spokesman Kor Oshon. Toyota, however, is a hesitant supporter, saying Honda's version of Effective Horsepower penalizes it. Studies show that at age five, the average Toyota loses only 32 pounds due to rust. Meanwhile, Mitsubishi wants an adjustment for the lower weight of its cars due to parts that fall off within five years. But Nissan wants no part of the Effective Horsepower program, claiming rust is a localized problem, only occurring in the snow belt, near ocean areas, and in places where it rains. None of the GM and Ford engines that have been tested have shown power losses. Some have shown power gains. For those who critcize Detroit for being stupid, one thing is clear: at least they're smart enough not to lie. >Nissan wants no part of the Effective Horsepower program, claiming >rust is a localized problem, only occurring in the snow belt, >near ocean areas, and in places where it rains.

For those who >critcize Detroit for being stupid, one thing is clear: at least >they're smart enough not to lie. Actually, Mazda (which is owned by Ford) did something similar when they introduced the RX-8, downrating its horsepower to 238 and offering to buy back vehciles from anyone who felt ripped off. And don't forget the big debacle over the 1999 Cobra, which was discovered after owners tested their cars on dynamometers. Ford took so long to find a fix that they cancelled production on the 2000 Cobras. They eventually had to replace exhaust systems and other parts in every 1999 Cobra they produced in order to actually achieve the advertised horsepower.

Sure does, but without salt rust just doesn't appear except on the exhaust system. I worked with a guy who restored old Fords (no accounting for taste!) in Phoenix and sold them to out-of-staters. They were all from the 50s and 60s and didn't have a trace of body rust, which made them very desirable... although I never figured out the attraction for a car with vacuum operated wipers and four wheel drum brakes.

Well, Studebaker kept the '57 style fin on the Hawk series all the way through '61... they're a bit much, but not bad looking overall.

I wonder why the US makers decided to go bonkers in the '58 MY and turn out less desirable designs. Mike >I wonder why the US makers decided to go bonkers in the '58 MY and turn out >less desirable designs. My take on it is that they had a styling theme and wanted to stick with it for 58 and were in the middle of the range in 57, dead on center at tasteful. Trying to keep the same theme but with substantial changes took them out of tasteful for that theme. I think we recently witnessed the same thing happening with aero styling. Conisider the first couple of renditions of the Taurus and then the one with the oval back glass. Same thing with the Intrepid and other LH cars. And the Pontiac Grand Prix that's so swoopy the back door beltline is at eye level for a back seat passenger. And current Dakota, Durango, and Ram versus the previous models. >> The best looking car I ever owned, and wished I had kept, was a 1957 Ford >>Fairlane 500 convertible with the 312 V8, 4 bbl carb.

The Europeans have tried to redefine a sports car as a car that goes fast through the turns. This completely ignores several fundamental realities of driving: a) Driving like this makes you throw up b) Just about all roadway corners do not have enough forward visibility to safely go around at 80Mph. While you may be easily able to stay in your lane, the big panel truck coming the opposite direction going 40Mph could easily have crossed over the centerline, and your not going to have enough road at that speed for him to get back over and for you to swerve safely The rest of the world doesen't like to look at straight-line performance because if they built cars that had it, very few of their customers would buy them. But, driving in a straight line is the safest possible way to race against the next guy on the public street, and there is nothing like being slammed back in your seat with powerful accelleration as the feeling of power in a car. Watch little kids playing with their HotWheels, they race against each other in a straight line, when have you ever seen little kids with toy cars pretending to saloom through a bunch of curves? How fun is that? little kids know what a fun car does, the only reason you have forgotten is because you have been reprogrammed by the advertisers who only have crappy product to sell. Rocket ships go stright with tons of accelleration. Racing jet boats go in a straight line with tons of accelleration. Drag cars and drag motorcycles go in a straight line with tons of accelleration, and you have not lived until you have sat on a 1000cc Kawasaki with wheelie bars and shot down a quarter mile at full throttle.

This helps traction in a RWD vehicle and decreases traction in a FWD vehicle. The Ford shouldn't spin its rear wheels while the front "claws up the hill" because the weight bias is towards the rear unless the transfer case or center differential has a bias towards the front wheels.

This is my first year with a diesel, and I can tell you it is a lot better suited to snowy hills than a gasser is - as long as I keep it from spinning the turbo up. The gasser had to be kept revved high enough that it wouldn't get carried away when traction got light, and that made the gears effectively higher. The diesel doggedly keeps turning at pretty much the same speed - giving or gaining rpms grudgingly. Having pushed 4X4s through snow as much as a foot deep (with some help from a shovel) on truly primitive roads from time to time, I can assure you it has nothing at all to do with engine weight. The truck body has so much weight it makes no difference whether the engine is a small block or a 6L diesel.

I suspect that the F250 4X4 needs better tires. True, but given that many pickups are driven with an empty bed, that transfer should be negligible. With a couple inches of snow back there, it should have improved the traction anyway. Point is that all 4 will spin at equal speeds - those that slip will spin while those that grip will pull/push the truck up the hill. >> When accelerating or going uphill, a portion of the vehicle's weight is >> transferred to the rear wheels.

If the tires can not gain traction, then there is no weight transfer to the rear, especially at startup, which is why I thought that the truck needed better tires. All 4 tires will not necessarily spin at equal speeds unless the vehicle is equipped with front and rear locking differentials and a transfer case or center locking differential. If any of the differentials are open, then the tire(s) with the least traction will spin while the others do nothing.

According to the web site on the link, the Quaife differential is not an open differential, although they say that it performs like an open differential during normal driving. An open differential is one that does not have any means of locking or limiting slip. By definition, the Quaife differential is not an open differential.

I guess my explanation of "open differential" was a little lacking. When a differential is "open" it does not mean that there is no locking or slip limiting mechanism or fluid. An open differential is simply a conventional differential. Any variation to the differential designed to transfer torque to the side with traction means that it is no longer ann "open" differential. Even Quaife says that their differential is better than an open differential - IOW, it is not "open." > more common lsd's use clutches, ratchets or locks to keep both wheels > turning together so some energy is still lost. i've not driven a quaife, > but from what i understand, always driving the wheel that gives traction > works like a charm.

A limited slip differential and a locking differential are not the same thing. A limited slip differential does lose some energy because kinetic energy is converted to heat. With a locked differential there is zero slippage and therefore zero energy loss when locked.. You were close but not quite correct in your example of a locked differential with both wheels turning together where one wheel has traction and the other does not.. In that example, it is the wheel/tire that is scrubbing the energy, not the differential.

When you work with a bunch of anal retentive engineers like I used to, it rubbs off. They would say that since the original discussion was differential efficiency, then the same would have to be true of a locked differential, with a foot note describing the enery loss from the tires. >> You were close but not quite correct in your example of a locked >> differential with both wheels turning together where one wheel has [quoted text clipped - 3 lines] > see above. i've been talking about energy transferred to the road all > along. We were talking about similar but different things. The nit picker in me would say that if we were discussing energy transfer to the road, then the words "energy transfer to the road" should have been included at the beginning of the discussion as opposed to differential energy. Since you were talking about energy transfer to the road, then you were correct, however, I still believe that your characterization of the Quaife diff as "open" is still incorrect because "open" does not mean the lack of clutches, silicone fluid, locking sleeves, etc. - I guess Quaife and I will have to agree to disagree with you there. ;-) SignatureRay O (correct punctuation to reply) > that's not true. lsd's with clutches lose energy big time. but that's > not what i'm getting at: if a diff is locked, both wheels turn > together, one has traction, the other not. the one that doesn't is > simply scrubbing energy away. Yes... but... An open diff will let your power get wasted onto the spinning wheel. A locked diff will make sure both spin at the same speed, so the power is distributed in proportion to the traction. This is a bit interesting in corners where you want the outside wheel to go farther (and hence faster) than the inside one. An LSD will transfer some of the energy from a spinning wheel back to the gripping one - but it wastes some too. It does however let you go round corners without eating tyres. They do "lose energy big time" but it's worth it as otherwise that energy, and more, would be wasted elsewhere.

The power delivered to the road is a multiple of speed and force. So if one wheel has twice as much grip as the other, twice as much power will go through it. (assuming they are both traction limited!) Yes, you will waste some - which is why the tyre smokes when you try really hard - but the *delivered* power will be proportional to the traction. Another rider - you may be delivering the power to the gravel, not the road!

Here is a pretty good explanation of suspension systems: http://www.carbibles.com/suspension_bible.html Every type of suspension system has trade-offs. In the ideal suspension system, the wheel will move up and down perpendicular to the road surface and maintain camber so that the tire maintains maximum contact and traction throughout the limits of wheel movement. Also, designers try to minimize unsprung weight to minimize wheel bounce. In a mass-produced vehicle, cost is a very big factor. A double wishbone suspension does a very good job at maintaining camber throughout its movement because it acts like a pantograph but is more expensive to produce than a strut suspension. A strut suspension generally has a lower control arm that the wheel is attached to. The lower control arm pivots where it is attached to the strut so the wheel's movement is actually an arc instead of straight vertical movement. The biggest advantage of a strut type suspension is that it is less expensive to produce while still providing more than adequate performance for every day street driving so you see it widely used on lower and mid-range cost vehicles. Rally cars do not have strut suspensions because they are great off road; they have strut suspensions because the stock versions of the cars have strut suspensions, and the stock versions have struts because they cost less to produce than other types of suspensions.

You sound like you have read a lot of auto enthusiast magazines but have not had formal training in automotive design, engineering, or service or experience working for an auto manufacturer. If you had, you would know instinctively that maintaining tire contact with the ground is more important in a low traction environment than in an environment where traction is not as much of an issue. You would also know that a strut suspension is not more or less susceptible to roll (I'm assuming that you are referring to body roll). Spring rates and anti-roll bars are what affect body roll. Most strut suspensions are more susceptible to camber changes. Also, wider tires do not make up for geometry issues. McPherson and Chapman strut suspensions are in wide use not because of their superior handling characteristics, but because they are inexpensive to make and lightweight. Most people know little or nothing about suspension designs so it sounds good when the automaker points out a "MacPherson Strut" suspension and so small and mid-size vehicles that are not actually performance oriented will have them installed. You usually will not see strut suspensions on performance and high-end vehicles, particularly those with RWD. Over the years, engineers have made improvements to strut suspension geometry to more closely approximate the better performing suspensions and they are certainly acceptable for the majority of the driving public, but a someone who is knowledgeable about automotive suspensions or performance would not hint that a strut suspension is the preferred design for any reason other than cost control.

I meant no insult, just an observation, and I apologize. My intent is to share the experience and knowledge I gained while working for an automaker and correct people's misconceptions about how cars work. The more people know about their cars, the more realistic their expectrations of the car's performance and the more satisfied they weill be with their car. When I said "know instinctively," I meant it from the point of view of a professional who spends all day working on and studying a subject and knows something without giving it consccicous thought. For example, a carpenter whose specialty is framing houses will know instinctively when he looks at a new house being built whether it is framed correctly or not.

I am always willing to listen and learn something new and I think the regulars in alt.autos.toyota will testify that I will admit when someone points out an error on my part.

I spent some time working for a fairly large auto maker and have had the benefit of working with and learning from automotive engineers, designers, and the technicians who had to work on them our in the real world.
