SAE CONFERENCE ON ROLLOVER AND STABILITY CONTROL
Troy, Michigan
May 16, 2000
************************************
I will try in my few minutes this afternoon to
give you a consumer view on the general topic of rollover and
stability control. Our perspective is based on 64 years of testing
and evaluating consumer products and services, (from cars and washing
machines to banking services, auto insurance, and life insurance) and
from fielding thousands of questions and comments from our readers
each year.
First, I would like to take a few moments to
describe where we are coming from-and I don't mean Yonkers, NY or
Colchester, CT.
Forget about stability control systems for a
moment and imagine that you and your partner are remodeling your
kitchen. Assume that today is Saturday, and you are going shopping
for appliances. And furthermore, that you don't have any special
knowledge about those appliances.
Will you choose the most advertised brand?
Will you buy what the salesperson advises? Will you buy the
cheapest, or the most expensive? I can tell you now, those
strategies are little more than guesses and hopes.
Today's marketplace is filled with a dizzying
array of choices. Consumers who seek value and quality, and who
attempt to make a rational selection from among the hundreds of
choices for, say, a refrigerator or a microwave oven, have precious
little in the way of information they feel they can trust to be
thorough and objective. Amidst the barrage of advertising hype and
claims by sales staff, consumers want and need useful advice that
puts their interests first and foremost.
Heading into the new Millennium, it is clear
that while the products we test will change with the market's
technological advancements, our core mission-Test, Inform,
Protect-will remain steadfast. We will continue to provide consumers
with practical advice they can use when it comes to shopping for
quality, value, and safety in their everyday lives-and not just when
they are buying products in the store or at the supermarket, but also
on the Internet.
And at the same time, we are also providing
manufacturers and retailers with a consumer yardstick for comparing
their products and services with those of their competitors.
When you think about it, Consumer Reports and
its comparative product information is a natural and vital component
of a free market. The ultimate success of our system-that is,
success for both seller and consumer-depends on consumers being fully
informed when making their purchase; that is, consumers who have
access to what economists call "perfect" information and who know how
to use that information.
Consumers Union serves as a major source and
conduit for that much-needed information, helping put consumers on a
more level playing field with manufacturers and retailers. We test
products using methods that reflect how we believe consumers will use
them, and we offer objective, unbiased test results about those
aspects of product quality that consumers don't have the ability or
opportunity to judge for themselves.
DESCRIPTION OF CU
In order to provide these judgments, we require
state-of-the-art laboratories, which we have in Yonkers, NY. Here,
Consumer Reports has 50 different test laboratories, including eight
environmental chambers, a very-low-frequency anechoic chamber for
testing audio products, an extensive food sensory laboratory, and a
modern video lab capable of generating the complex signals needed for
evaluating today's TVs, VCRs, and camcorders. We also have a
fantastic auto test facility, with its own track, located on 327
acres in East Haddam, CT where we test new cars, minivans, pickup
trucks, SUVs, tires and many after-market auto products.
INDEPENDENCE
At the heart of our work is our complete
independence from the manufacturers and sellers of products and
services. After 64 years, Consumer Reports still does not accept any
outside advertising nor any gifts or grants from commercial entities.
The same is true of our other publications. Consumers need
objective, unbiased advice, and they can be assured that our
information is free from any influence or control by manufacturers,
distributors, or retailers. Rather than accept outside advertising
revenues from sellers, which no doubt could have been substantial,
the support for our work has always come from the consumer-our only
client. Acceptance and trust by consumers to purchase and use this
information is how we keep going.
Our primary focus is on the relevance and the
quality of our testing-and not on any particular results. We are
organized to do our work in such a way that we literally do not care
which product does the best or the worst. We simply have no stake in
the outcome, financial or otherwise. And since we do not have a
vested interest in any company or product, our independence allows us
the unique luxury to wish out loud for better value, and to be
critical where we think consumers are being shortchanged or put at
risk unnecessarily. We think this role is as much a part of our job
as providing comparative test ratings. In my opinion, both industry
and consumers benefit from this approach.
Another element contributing to our
independence is that we do not accept product samples from any
manufacturer, free or otherwise. We buy all our test samples,
including automobiles, on the open market with cash or credit card,
just as a consumer would. And we are becoming avid shoppers over the
Internet, both to be faster and more efficient in our work, and to
experience what you experience as consumers.
When our shoppers are at the checkout counter,
their purchases are not quite as ordinary as the average consumer's,
which often leads to an amusing exchange between shopper and cashier.
Imagine yourself checking out with 20 pounds of different coffees,
or 10 dozen condoms, or 13 bathroom scales. (People do look at you
funny.) But their hard work pays off in fulfilling the rigorous
sampling designs required for many of our product reports.
By the way, based on our tests of nearly 5,000
alkaline batteries, we offer the consumer this general advice: Buy
by price. The one exception: digital and automated flash cameras
are best served by the Duracell Ultra battery.
Sometimes, we have to go to extraordinary
lengths to complete our sampling of products found around the
country. When CU tested condoms, one aspect was to see how those
condoms distributed publicly, that is, through clinics and vending
machines, stacked up against those purchased at pharmacies. The
shopper in charge of this project had to gather more than 20,000
condoms. But when it came time to finding condoms sold in vending
machines, the only places he could find them were nightclubs. He
spent many an hour self-consciously feeding coins into the machines
located in various nightclub men's rooms. In the end, he was
successful in getting the range of samples we needed. As you may
have read in our published report, vending machine-condoms did just
fine in our tests.
We buy around 40 cars, trucks, minivans, and
SUVs per year-again with cash on the open market.
As you can see, because of our constant vigil
to remain independent, there should never be any question regarding
even the possibility of bias for or against a particular manufacturer
or brand name. We make every effort we can to eliminate even the
slightest chance that bias or favoritism could creep into our work.
TESTING AT CU
An important word about those test protocols.
Much of what we do is taken directly from standard industry tests,
but very often we create our own test procedures, where we believe
they are warranted. Our test procedures have indeed influenced
industry standards-and are not a secret to any manufacturer whose
products we test.
Our primary goal is to provide information that
is pertinent to the consumer's needs. Our test programs are designed
to incorporate our knowledge of what the consumer is likely to do
with the product, as well as what the manufacturer advises the
consumer to do. Sometimes the two are quite different.
In general, comparative testing does not yield
the same information as compliance and quality control tests. They
are vastly different approaches, serving distinctly different needs.
Testing to meet a commercial standard of acceptance, for example, is
a business requirement for manufacturers, distributors, and
retailers. Comparative testing to determine which products in a
group offer the best performance and/or the best value to the
consumer is a requirement for us. Sometimes the two overlap. Often
they don't.
BENEFITS FOR CONSUMERS AND MANUFACTURERS
There may be some folks who believe that
Consumers Union is anti-business. We would firmly disagree, as we
consider fairness to business an important requirement of our work.
But we also acknowledge that we are fiercely pro-consumer, and
dedicated to applying the best of technology and research to
strengthen the consumer's position in the marketplace. We look for
ways that products generally could be improved, and sometimes urge
that the acceptance bar within industry standards be raised. To that
end, several of our staff serve on industry voluntary standards
committees, presenting a consumer perspective in the development
process.
We do call it like we see it, regardless of the
outcome. When a product performs outstandingly well, we let
consumers and the public know that. And when a product performs in a
Not Acceptable manner, we waste no time thoroughly researching the
implications of that performance and making that news public-always
making sure that you, the consumer, are the first to hear, as you are
our client.
In summary, when it comes down to it, when the
consumer is able to reliably know product performance when he or she
is making a choice, competition is keener and fairer for both
consumers and manufacturers. Products and services become safer,
more reliable, and of greater value. And that was our goal to begin
with-A marketplace filled with products and services that are all
reasonably safe, and that offer in a clear manner a range of quality
choices to be selected by the consumer. In the end, consumers should
be able to choose what they want-and get what they choose.
ROLLOVER AND STABILITY CONTROL
Now that I have sketched CU's background, you
have a context for interpreting our published test findings and
recommendations. For us, evaluating product safety is one of our
highest priorities. As with many risks, the level of safety offered
by a particular product is generally hidden from the consumer's
untrained eye. Moreover, most consumers do not have the training or
time or inclination to make such evaluations on their own. Many even
think that a product wouldn't be on the market in the first place if
there was something wrong or unsafe about it.
For example, no consumer standing in the
showroom can discern which model has ABS simply by looking at the
car. Indeed, few consumers standing the showroom-based on what they
see in showroom-can decide they even want ABS. A consumer's interest
in ABS is more the result of intense public education and
advertising, and advice from trusted advisers like neighbors,
friends, and yes, Consumer Reports.
Rather than focusing on hidden safety features
used primarily for rare events, consumers will focus more on the
things that are observable, and affect their pleasure and personal
experiences with the vehicle on a daily basis-like color, comfort,
convenience, and what kind of stereo system they want.
But as you know, and we know, things are
changing. The safety of vehicles has risen in the last few years to
be one of the most important attributes in the consumer's decision.
At CU we receive far more questions today than we did, say, 10 or 15
years ago, asking which models are the safest, or "how do I get a
really safe car"? So while many consumers cannot themselves
determine the safety of their choices, they do expect and demand
safer models for themselves and their families.
That is why the subject of this seminar is so
important to everyone. It gets away from finding whom to blame for a
rollover accident, and instead seeks to prevent rollovers at the
start. Blame game dynamics solves very little.
This safety problem crept up on us all. Sales
have increased from only a small number of SUVs in the 60's to the
hundreds of thousands now sold annually. Many of the early users
were farmers and public utility and construction workers. These
drivers generally understood the vehicles and, more importantly,
their limitations.
Today's SUVs have virtually replaced the family
station wagon. They are everywhere and in large numbers, whether in
shopping malls or parked adjacent to little league ball fields. And
they are now being used by more people who have less knowledge of how
differently these vehicles handle.
Moreover, since the sales boom in the 90's,
older models will move into the second-hand market where drivers are
younger and less skilled, possibly making them a greater hazard in
rollover and other multi-vehicle accidents.
In our tests, the early SUVs were slow and
cumbersome to handle. Nowadays, our test vehicles are every bit as
fast as cars, and their handling is quick and nimble. This can lead
drivers into a false sense of security, where they may find
themselves driving too fast for the vehicle's ability to avoid an
obstacle safely. Rollover fatalities are on the increase, and we
worry that it has not peaked yet.
We are also aware of many after-market tire and
rim combinations that could adversely affect the handling of an SUV.
Although we have not tested these products, we are concerned that
these after-market tires can generate higher lateral forces that
exceed the vehicle's design limits, thus causing the vehicle to be
less stable in emergency situations. A recent RMA bulletin
specifically warns after-market dealers about this issue.
Of course, the owner's manuals in many SUVs
specifically warn the owner of the need to fit only OE tire size and
construction. But what's in the owner's manuals is often among the
world's best-kept secrets.
Modern technology can indeed improve the safety
of SUVs, and we would like to see a more widespread use of stability
control systems. Likewise, active handling systems can also help by
reducing the body roll. The introduction of side airbag curtains to
help prevent head impacts and ejection during a rollover incident is
also a welcome development, but only as a Band-Aid for the rollover
issue.
Our auto test engineers believe that to make
future SUVs and Crossover vehicles safer for the average consumer to
drive, several actions are warranted: 1) a greater emphasis on
improving the suspension systems, 2) more effort to lower the center
of gravity, and 3) wider use of stability control systems. We have
evaluated several vehicles with stability control systems, and in our
opinion, their performance in our avoidance maneuver tests was quite
impressive. In one case, we were able to switch the system ON and
OFF, and noted that performance with the system ON was noticeably
improved.
In the end, reducing death and serious injury
from rollover will be achieved best by improving the product-rather
than warning the consumer to alter his or her behavior to accommodate
to a dangerous design. Labels don't help much when you are
confronted by a sudden emergency. Fortunately, because of your
efforts, the remedies available to manufacturers are technologically
and economically feasible.
We greatly appreciate SAE's hosting this
seminar and identifying rollover as a serious safety issue-something
not on the agenda just a few years ago.
I thank you for your attention.
