Robert A. Lutz: ON THE 2006 PONTIAC SOLSTICE
The Solstice, by virtue of the very small investment and the good margins on
the car can be produced very profitably at 20,000 per year. [The vehicle will
be produced at the Wilmington, Delaware, Assembly Plant, which is presently
a Saturn plant.] That doesnt mean we get the money back in a year, but
over a two or three-year run its a very profitable program. Now that all
of the bits and pieces are in placethe Ecotec four-cylinder engine, the
rear differential, prop shaft, five-speed transmission, the automatic that will
come the year after the introduction of the manualall of those things
being in place, lengthening the architecture to make a Nomad or Curve or something
is really not an investment-intensive thing to do. [The Chevy Nomad and Saturn
Curve are both concept vehicles based on the same rear-wheel-drive Kappa
architecture that was developed for the Solstice.]

Bob Lutz and the Pontiac Solstice: If you build cars that people want, then
you can charge more for them (or at least minimize the amount of cash on the
hood). When the Solstice comes rolling out, Pontiac should have no trouble moving
that desirable sheetmeal.
Robert A, Lutz
GM vice chairman Product Development
and chairman, GM North America

The Solstice has the primary purpose of helping with the revitalization of the
Pontiac brand. Its not so much the volume the Solstice does as the signal
it sends about our intentions about where we want Pontiac to be in terms of
brand character. But having said that, its a profitable car in its own
right. The whole trick here is to overcome this old Detroit myth that you cant
make money on small cars. You can make money on small cars, but they have to
be interesting small cars. If theyre commodity small cars, then basically
nobody wants them because theyre not aspirational. Look at the BMW Mini.
Its a small carand at current exchange rates Im not sure that
theyre not losing money on itbut under normal circumstances, when
you look at what that car is selling for, it should be a very profitable car
because people want it, as opposed to being willing to take it.
ON THE VALUE OF DESIGN& DESIRE
If you look at the content on Kappa, the amount of metal, the so-called material
cost, is really not much higher than a [2005 Chevrolet] Cobalt. The stuff is
arranged differently. Its rear-wheel-drive instead of front-wheel-drive.
But they both have a transmission. They both have a four-cylinder engine. The
Solstice has a folding top, which is more expensive, but on the other hand it
only has two doors instead of four, it has two electric window motors instead
of four, so roughly speaking, the material cost is not that different. [Note:
the Chevy Cobalt is also available as a coupe.]
Youve got the situation when youre down in the small front-wheel-drive
segment, the public expects those things to sell for about fourteen and a half.
But when you package the same thing as a roadster, everybody says Wow!
Under 20? This is amazing.
Thats why the Chrysler PT Cruiser was so profitable. It was basically
a Neon plus a couple hundred bucks, but suddenly instead of selling for $13,000,
it sold for $21,000. That difference in selling price makes those cars profitable.
We are emphasizing design because design is becoming a major differentiator
in the market in that everyone is beginning to realize that J.D. Power quality
is no longer a differentiator. Just when the American companiesespecially
GMare really getting good at it, it really isnt a big differentiator
anymore. You can take the guy who is at the bottom at the J.D. Power ranking
and the score is such that seven years ago he would have been better than the
best Japanese. It is getting so compressed that anyone can go out and buy anything
and they know that theyre going to have an impeccable, flawless, reliable
car that can be driven for years and years, and nothing is going to break on
it. So on cars that are more reliable, were starting to split hairs here,
and I think the public is figuring it out.
Fuel economy is about the same in every category. Everybody uses the same technology,
so no huge difference in fuel economy. Everyone has about the same level of
aerodynamics. Everybody has about the same level of features. So really what
it boils down to is: Do I like the car or not? If all other things
are equal, then picking on the basis of appearance is a completely rational
decision. It wasnt rational 30 years ago when you had to tell yourself,
Wait a minute. A car is more than a pretty face. I may fall in love with
this car, but everything I read and hear from my friends is that the thing starts
falling apart after six months, so Id better go with old tried-and-true.
Thats not the case anymore. You can with abandon go pick what looks best
to you and you know youre going to have a great vehicle.
Its really depressing that there are no bad products any more.
ON SATURN
If you look at the history of Saturnand its very easy for me to
criticize because I wasnt heremaybe we relied too much on the appeal
of Saturn for people who really dont care that much about the car, but
they care about the dealership, the care they receive, the courtesy thats
awarded them. In other words, it was more the purchasing and ownership experience
and there was less focus on We want you to fall in love with the car.
And that has resulted in a degree of blandness or absence of character for some
of the Saturn models. Thats what we have to correct. We have to give Saturn
vehicles that are compelling to where people who have never considered Saturn
say, Wow! That is terrific. Im going to go to a Saturn dealer because
I want to take a closer look. We really have to crank up the sex appeal
of the Saturn product line. We can and we will.
Why should I have to choose between exciting cars in a normal dealership or
uninteresting cars in a dealership that treats me well? Thats like a restaurant
that says, What do you wantclean tablecloths or good food?
Could I have both, please? I think thats where the error in
the thinking was: That Saturn doesnt need exciting cars because people
go there for the experience.
ON TRUCKS
The march toward more and more truck-like vehicles is unstoppable, I think.
Its unstoppable on both sides of the Atlantic. You see the same thing
happening gradually in Europe, where there are more and more SUV-like vehicles
of various sizes and minivan-type vehicles, as well. Its unstoppable.
ON CARS
We certainly realize that while we have made a very successful investment in
upgrading GMs truck presence, we have possibly not neglected carsbut
we couldnt do it all at once. We lost some position in the passenger car
business and we need to stabilize or regrow General Motors position in
passenger cars. If we dont grow numerically, I would hope that at least
we grow it qualitatively. If with a much more appealing passenger car lineup
thats much more competitive, I would hope that we can lower the level
of incentives that it takes to move the cars. If we could get the average midsize
passenger car off of a $4,000 rebate to something more like a $2,000 rebate,
the whole effort will have been hugely worthwhile. If you take two or three
million and multiply it by $2,000, it ends up at a large million-dollar figure
very quickly.
ON THE EFFECT OF 2005 EUROPEAN PEDESTRIAN SAFETY REGS ON DESIGN
The 2005 pedestrian protection legislating in Europe is just going to radically
change the look of automobiles in Europe post-2005.
Cars like the Mercedes 500SL or the McLaren Mercedesall of these are going
to have to be radically reconfigured in the next generation because you need
10 cm between the sheet metal and the first hard spot under the hood. If you
can imagine the Nomad, Curve or Solstice with the hood higher, I dare say it
would spoil the design concept considerably. Which is one reason why I think
the Volkswagen roadster that was shown as a concept in Frankfurt was mid-engine.
That way the front end is empty. That is a huge enabler to meeting the law.
The next generation of European cars is going to look different. You can see
a precursor to that in the Audi design: very horizontal hoods and then sharp,
flat front end. A little bit like the new Chryslers. The 300C and Dodge Magnum.
I asked Dieter Zetsche [president and CEO of Chrysler Group], Did you
guys do this front end because of pedestrian protection? It looks like they
would meet European pedestrian protection. Dieter said no, they dont
quite meet it. But that is the kind of styling you will see a lot of until people
come up with the active devices, but thats years away. It takes all the
sensor technology and you also need a 20 cm band around the front of the car
thats absolutely flat so that if you hit a persons leg theres
no stress concentration. They want the impact stress spread over as large a
surface as possible so that the pedestrian legs get swept out from under him
without breaking. They want the pedestrian to rotate and hit the soft hood that
would absorb the impact.
ON GENERAL MOTORS
Are we as good as we want to be? No. Is our product lineup to where we will
reachieve market dominance in a very short time? The answer is also no. But
I will tell you this: I think we are in the best relative position compared
to the rest of the industry, foreign or domestic, than the company has been
in the last 10 or 12 years. The company is definitely marching in the right
direction. And dont forget: Theres a lot more ammunition in our
magazine that will be revealed.
Were in the best relative position, and our position relative to the rest
of the industry is vastly better than it was 3, 4, 5, 2 years ago.
ON HYBRIDS
Hybrids are an interesting curiosity. We will do some because you cant
stay away from a trend like that, but do they make economic sense at $1.50 a
gallon? No, they do not. Even if some of our competitors say Were
in mass production, the cost is coming down. Of course its coming
down, but its still going to be way more than a conventional car because
youve got the internal combustion power train, the electric power train,
the battery pack and all the computer controls that cause the whole thing to
blend together. Theyre significantly more expensive than a conventional
car.
If you start with a vehicle that consumes 27 liters per hundred kilometers and
get it to 18, now you have saved 9 liters for every 100 km driven. Then take
a car that consumes 6 liters and take it down to 4. You save 2. Why wouldnt
you want to get the percentage improvement where the fuel is really saved and
where the people really want the cars as opposed to little cars that people
really dont care that much about?

Through the implementation of the GM Global Manufacturing System, Gary Cowger points out that when it comes to quality and productivity, the company is on a rolldespite the fact that he believes many in the public would still think that GM isnt as good as its Japanese competitors.
Gary L. Cowger
President, GM North America

We do have CAFE legislation on light trucks. With the continuing desire on the
part of the public to buy large V8 sport utilities like Suburbans, Denalis,
Yukon XLs, and so forth, if everybody starts buying those, we would have a huge
problem making the truck CAFE numbers. So what do you do?
You could make some smaller, lighter trucks to try to compensate for the big
ones and get the average right, and we are going to pursue some of that. Or
you introduce some expensive technology into your big SUVs which would drastically
reduce fuel consumption. You can sell far more of them before you get into the
CAFE-bind situation. Plus, up there you have some margins to where you can take
the hybrid system. If we had to, we could probably eat the cost and still have
a margin.
Gary L. Cowger: ON THE CHANGE IN GM MANUFACTURING
People keep saying,GM what happened?
Over night! I say this is a 12-year overnight miracle. You
saw how long it took us. How many years did we go to NUMMI in just complete
denial? That is the issue. Who has the profound knowledge? I look back on all
those dinners I had with Dr. Deming when he said [smacks the table], Gary,
you cant walk through a plant and understand someones profound knowledge,
do you understand that young man? Id go, Yeah, but I
didnt have a clue what the hell he was talking about. But I do understand
it now.
You cannot walk through and understand the Toyota Production System. Youve
got to experience it, learn it, and understand what its driving. This
whole idea of focus on the operator was the way that I finally interpreted it
so that it got some legs for people to understand: If the operator adds more
value and cant make a mistake because you sit there and do something 60
times an hour, even the best person can make a mistake. That starts driving
the system, the profound knowledge, the batch size of one, poka yoke, work placement,
work movementall of that comes last, not first. Youve got to have
that in mind. The good news is that once you get it, the improvements just start
exponentially. The GMS system [Global Manufacturing System] is now in every
factory we have worldwide. When you look at our direct run rates, weve
got direct run rates that are better than our Asian competitors in some plants.
You can tell the difference. You walk through five years ago and walk through
todayits just like a machine today. Thats the profound knowledge
you get with the manufacturing system put in place.
When you look at our production schedules today, we dont vary a percent.
You used to look at them and they were all over the mapthroughput, quality,
productivity are all measures of how well your manufacturing system is working.
ON QUALITY
The perception out there today is that Japanese quality is better than everybody
elses. Not true. Look at all the data. In many of the categories, the
domestics lead, but you wouldnt believe it by reading the newspaper. Eight
of the top 10 plants in quality in North and South America are GM plants. If
we went out and gave the public a test on that, I dont think theyd
believe it.
ON LOWER PRODUCTION RUNS
Im not sure 20,000 [is the right number for a production run]. The break
even is coming down dramatically. You can make 20,000 at the right price point,
but under $20,000 is probably not the right price point. But if you drive enough
derivatives off that, it will be a very profitable architecture [e.g., Kappa].
50,000? Absolutely. One of the big capital requirements we had was that every
time we did a new model, whether it was a little one in low volume or a big
one in high volume, you went in and spent $300-million to $400-million on a
body shop. Today, in Lansing Grand River Assembly [where the Cadillac CTS and
SRX are built], we can have a major changea completely different carfor
$40-million. Youre talking a factor of 10X here. It has improved dramatically.
As for technology, as we take C-Flex [a programmable body shop tooling system
that replaces body style-specific tooling and related equipment. It allows multiple
body panels (floor pans, deck lids, hoods, engine compartments, etc.) to be
welded with the same set of programmable tools and robots. Model specific tooling
is not required.] and move it to Tru-Flex [a body shop enhancement that features
a flexible underbody marriage assembly system and utilizes both C-Flex and multi-robot
cooperative welding] and as sensor technology continues to improve and you really
get mechanical-electrical systems to actually work in harmony with each other,
it will keep coming down. As you utilize suppliers more effectively, as you
get integrated builds and more integrated subassembliescontinuous improvement.
ON THE AUTO COMPANIES THAT CONCERN HIM They all do. I believe in Andy Groves
book Only the Paranoid Survive. Trust me. Im paranoid about all of them.
I really am. You walk around the show, and everyones got good products.
Youve got to worry about all of them.

Hogan and the Kappa architecture. This was a fast product developmentpart
of Hogans mandate (and objective) as they work toward getting more products
to market sooner.
Mark T. Hogan
GM Group Vice President, Advanced Vehicle Development
|
Mark T. Hogan: ON WHAT HIS ORGANIZATION DOES
My operation is responsible for taking the product development portfolio and
making sure we can execute it from an engineering and business case standpoint.
The prior process had that responsibility diffused into a number of different
areas. Now we have one group, clearly responsible and empowered for doing that.
That allows us to pull engineering resources up front. So when we get to what
we call clay freeze or vehicle production intent, weve
got a 70% engineered solution, which allows us to go faster to start of production.
Its a multifunctional, empowered staff that runs on a matrix that reports
to me. We have all of the decision makers and functions represented. There is
a lot more timing rigor in the upfront process.
ON ADVANCED PRODUCT DEVELOPMENT: TIMING & SPEED
The first fruits of our process are the Kappas. We are optimistic that the process
development program as weve laid it out two years ago is moving along.
Weve taken time out of our development cycle. Were down, on average,
to about 30 months. When I got into this job it was more of a 36-month average,
from design freeze to start of production [Hogan assumed his position in February,
2002]. We call it VPI: Vehicle Production Intent. Weve gone as fast as
16 months with H2. Some could be longer. Solstice will be 24. The faster the
better. We definitely want to improve over 30.
Its dependent on how much carryover architecture youre using. If
youve got a carryover powertrain, an architecture with common suspension
design solutions or steering system solutions, you can go real fast because
then it turns into a body program. And a body program now, with die development
going as fast as five or six months, its not out of the question you could
do a 12-month program.
For the long lead itemspowertrain development, fascia or bumper sys-tems,
and headlampsthey take longer to accommodate in the new architecture.
ON THE IMPORTANCE OF MATH
From a technological standpoint, the advent of math tools allows us to essentially
eliminate what we call alpha or mule builds with hand-built
hardware. We can actually validate in the computer. In the case of a new architecture,
it could save 12 months. Its been a big improvement. And then from a decision-making
standpoint, we had some redundancy in our product development decision-making
that weve taken out with our new process.
If youre taking time out and giving your designing engineer more of a
subsystem responsibility as opposed to a discrete part number, youre going
to be able to go faster. The math tool broadens the toolbox of the designing
engineer as well as speeds up the time they need to get the job done.
With math-based tools, the ability to pass design solutions off and iterate
them on a global basis is far easier than it was three or four years ago.
ON MAKING THE CASE
Several key elements to making sure the business case works. One is around capital
investmentboth internal and in vendor tooling. One is on material cost,
which includes assembly labor. And the other is engineering workload. If you
can balance those three elements and arrive at a price point where you can take
your volume forecasts, where we feel we can make money or not. At that point
we say go or no-go. To pass through VPI we have to be very sure we can make
those business targets.
The days of the 300,000 unit runs are over, by and large. You still get Camrys
and Accords and Impalas. But by and large, the markets tending to be in
the 50,000 to 100,000-unit chunks. That means were going to have more
products by definition if were going to keep our volume up. And the enablers
for doing that are obviously embedded in our vehicle development process and
math-based tools, as well as process improvement both in terms of die development
and in terms of manufacturing flexibilityso you dont have to spend
a lot of time changing over a plant. We shoot for zero downtime when we make
a change.
Were doing Solstice for $100,000,000. We have to because it has a three-
or four-year product life. Roadsters dont have a long shelf life.
ON BENCHMARKING
We pay close attention to Toyota. We can do that through our work on Vibe. Understand
a lot more about the Honda process in part because we do engines with them.
And we obviously try to pay attention to the other competitors to the extent
that we can without being in the bowels of their organizations.
ON THE BENEFIT OF GMS BRANDS
Weve got a number of brands we have to feed. They each have a certain
place in the marketplace. We try to think about what their purpose is in the
marketplace, what their distribution channel looks like, and that tells us what
kind of product array we should have. For example, most of our Pontiac, Buick
and GMC dealers are in the same showroom. So it doesnt make sense for
us necessarily to have a two-seat roadster for Buick when were doing the
Solstice for Pontiac. That doesnt mean we wont have common product
responses in a showroom, but we pay attention to that. That combined with where
we want to be with the brandfor example, we want Saturn to gain back some
of its youthful exuberance that its gradually lost over time, so the Saturn
Curve or the Ion Redline or the Vue, those are products we think about in terms
of rejuvenating Saturn. 60% of Saturn customers: their second choice is an import.
When we started it was 80%. We want to get back to 80%. The way we do that is
to have product they dont expect to be coming out of Saturn or GM. Curve
is certainly one of those.
ON COVISINT
Covisint was thought to be a great example of a B-to-B solution that would take
cost out of the system. It never materialized. The suppliers didnt buy
it. When the dogs dont eat the dog food, the dog food company goes out
of business. [Hogan was the president of e-GM prior to his current position.]

In his new role as head of GM North American Design, Ed Welburn is looking for
clean designs that will endure.
Edward T. Welburn
GM North America vice president, Design Center
|
Edward T. Welburn: ON WHAT HE DOESAND DOESNT DO
Well, Im managing Design, so I feel that Im designing. The team
of designers is so talented. Creative. Number one, I dont have to draw.
And I dont think it would be appropriate, it would throw off the judgment
if I were in there sketching along with them. At times in private, I enjoy drawing
and sketching. I continue to do that. Its a good way of thinking through
a design challenge that weve got. In my own quiet time, to think through
a design. So that when I go into a review, it helps.
ON HOW A PROJECT IS DONE
Wed have two, maybe three, teams that would begin work on it in isolation.
Developing ideas, developing thoughts. Then wed bring those ideas together
for review. Ideas come from West Coast studio, UK, one of our global partnerswe
might ask them to take a look at it. The Saab design team did the Saturn Curve
exterior. As those ideas come together and we have a critique and then the design
goes forward. Its just in our in our blood to want to sketch and think
through the ideas.
ON WHAT HED LIKE TO BE REMEMBERED FOR
Designs that were bold, designs that really connected with customers in a very
emotional way. Designs that were very diverse, that covered the market, the
entire market, from the most aggressive design to the designs that were more
quietbut in all cases, very fresh designs. Very well executed. Very well
detailed. Very precise designs. That span the test of time.
We have a relationship between design and engineering, throughout product development,
that makes that kind of thing happen in a way that we hadnt been able
to do years ago. Theres a product development process that allows us to
take a Solstice concept vehicle and in two years have in place an all-new architecture,
an exciting architecture with terrific proportions that allows great design
to occur.
When you get the proportions rightand you must get the proportions rightyou
can do a much cleaner designthe statement is in the overall shape, in
the gesture of the design, in the proportions.
ON WHAT ENDURES
I think clean designs are the designs that stay fresh longer. When there are
vehicles that are 10, 20, 50 years old. When you look back at the history of
automobile designI think in product design in generalthe clean designs
are the ones that weather the times better. In order to achieve clean design,
you must have great proportions. In order to get great proportions you need
to have a good working relationship between design and engineering. Right up
front, a common vision that allows you to get to that point.
ON HOW CONCEPTS COMMENCE
Theres some real strategic work that happens before we begin work on a
concept vehicle. Theres some very keen planning that occurs. Theres
a great engineering team that Mark Reuss [GM executive director, Engineering
Architecture & Specialty Vehicles Design Centers] leads that is very much
a part of the planning of the concept from the very beginning. And the designers
begin to work. Theres some real thought that goes into the design of a
particular concept. Each concept has a different mission. In some cases, Heres
a great idea for a new production vehicle. In other cases its more,
Heres a direction for the brand. The concept is bigger than
one vehicle. It is a statement for the brand. Every particular concept has a
different vision. Some of them are just real exploration into a new vehicle
type. There are other concepts done internally that we dont share with
the public. But I think that it is that real strategic work. What is the right
vehicle to do for next year? What is the mission of that vehiclebefore
we get too deep into the design itself.
ON TECHNOLOGY & TOOLS FOR DESIGN
With each shift in technology, theres a learning curve we go through.
The same is true when design went to clay. We didnt work in clay. We worked
in wood. Theres an understanding of how to work in that medium. We knew
long term that there were shapes we couldnt make in wood, or easily make,
but it took an understanding of how we are going to use the clay, keep it soft
and pliable. Mathweve gone through that same learning curve. There
are a lot of people who feel that a design developed in math is going to be
sterile, harsh, wont have life, energy, emotion. The SSR, the concept
vehicle, was developed totally in math. There was no clay model at all. I think
it is a pretty emotional statement.
Since then, math has been an integral part in the development of our vehicles.
We still use clay and we will use clay in our development. But math is very
integral, very important. It allows us to move quickly. It allows us to communicate
much earlier with our engineering partners. If we can do that, then it aids
us to get the kind of proportions, the kind of vehicles that we all want. If
we can communicate with the engineers earlier. It also allows us to create solutions
quicker and then spend more time on the refinement.
Virtual reality is a great tool and we use it all day, every day. Very important
tool. But to take that math data and mill out a clay model and fine-tune that
clay model and walk around it is very important. We have great reviews, the
design team. Great reviews with the leadership of the company, theyre
all in on a very regular basis to review the designs; it is a high priority
with them. Those models are important.
ON THE TREND OF NO TREND
This is something that Ive been talking about for a while that is absolutely
fabulous. There is no one trend. There are a lot of things happening, but there
is no one trend. Its just wonderful for a customerthe choices. Its
true in our industry. Its true in other industries. Look at architecture.
Theres just incredible architecture going up. Its not all the same
50-story boxes with mirrored glass. Very expressive stuff being done. At the
same time, restoration of historic buildings is bigger than at any other time.
Its fabulous.
Consider fashion design. There was a time when hemlines were a big deal. High
or low. Its all over the map now. Mens suitslapel widths.
Narrow, wide. Today, its all over the mapeven within a particular
brand. Look at a Hugo Boss or Armani; theyll have lapel widths that are
all over. The materials. The proportions. Choices. All forms of designs. Its
a wonderful time with all the choices the customers have.
Look at the supercars. Lamborghinivery strong design. Ford GT. Both mid-engine
supercars. Both are relevant. Both look fantastic. Both are appropriate for
the time. And a supercar doesnt even have to be mid-engine. It can be
a front-engine vehiclean Aston Martin.
ON WORKING WITH INDUSTRY OUTSIDERS
We work with Bulgari. Its neat to visit their studio. Its a very
small studio. They use the same tools we use. We can communicate with them.
We put a Bulgari clock in the Cadillac; were looking at other opportunities
to expand that relationship. It is fascinating to talk. They bring up designs
on the tube and we talk like were old pals working together. It is a good
learning experience. When we send a designer over to Bulgari or have a Bulgari
designer in one of our studios, its a great benefit.
That whole relationship with Nike is fantastic [on the Hummer H3T concept].
Both of us benefited on that project.
Youll be seeing some things pretty soonrelationships with architects.
Very well-known architects. It will be very creative and help us both.

If the issue is one of reducing the dependency on petroleum, then the solution
is hydrogen power, maintains Larry Burns.
Lawrence D. Burns
GM vice president, Research & Development and Planning
|
Lawrence D. Burns: ON DEVELOPING THE FUEL CELL-POWERED VEHICLE
Weve got two goals out there.
Commercial viability by 2010. Be the first company to build and sell a million
profitably. We havent put a date on that second goal. You certainly have
to have commercial viability before you can even think about the second goal.
So you can conclude were not talking about a million before 2010. How
quickly you can get to a million once youve proven commercial viability
is going to depend on some things we dont totally control ourselves, like
infrastructure, availability of hydrogen, codes and standards. We want to know
by 2010 that if youre building real volume of these kinds of vehicles,
you can do that at $50/kW and that the car is going to be exciting.
Were confident we can deliver the first step in our overall mission.
ON THE HIGH COST OF TODAYS FUEL CELL
Its an overall systems hurdle, not any one thing. Its the integration
of a lot of things. When you look at the stack, you have some fairly sophisticated
material in that middle membrane. Some material on each side of that material
that are important with respect to how you get the hydrogen evenly distributed
over the membrane and how you manage the water on the cathode side. Then youve
got the plates that are on both sides of the diffusion material. Its a
combination of the material selection for the plates, the diffusion media, and
the membrane. And the management of the flow of the hydrogen, the air and the
water: To do that in such a way that youre absolutely maximizing the amount
of current and power youre generating per square centimeter on the surface
of those materials. To do that in such a way that you dont have corrosion
that would reduce your durability. And to do it in such a way that you dont
have deterioration of the membrane, which would reduce durability. Thats
the stack portion.
The other part of the $50/kW is the hydrogen storage. When we talk $50/kW,
its from stored hydrogen to torque at the wheels. Were not worried
about the electric motors that take advantage of the electricity. Thats
commodity-type stuff. Were not overly worried about the power electronics
and the controls. We know how to do that. Weve shown with HydroGen3 that
we can take gaseous hydrogen, put it into the stack, generate electricity, and
have the car respond as we want it to respond. Thats a pretty big deal.
We dont have a battery sitting there with a bunch of stored energy on
HydroGen3 to give you the transient responses for the car; were doing
it directly from the hydrogen flowing into the stack and the electricity coming
out of the stack. We know how to do that. There hasnt been enough work
done by the world on hydrogen storage. There hasnt been a reason for it
until recently. You look at liquid hydrogen tankstheyre pretty crude,
quite honestly. They were not developed with high-volume automotive applications
in mind. Theres great engineering opportunity. The valves tend to be inside
the tanks; we think they can be engineered to be external to the tanks. The
geometry of the tanks has been assumed to be a cylinder; we think the geometry
can be very exciting as a packaging enabler. You have to get that combination
of design and cost right.
Scale economies are going to be important.
But its going to be materials, understanding the basic physics and chemistry
of whats going on to get you the maximum power density out of the available
material. Weve got the industry-leading power density thats been
made publicly known. I cant tell you where we are in the lab, but its
significantly beyond what weve stated publicly. Thats going to be
a critically important variable, because if you double the power density, you
get the same amount of power for half the material. The cost of this thing is
ultimately material. That becomes the central variable.
ON FUEL CELLS & THE INNOVATORS DILEMMA
Christensens Innovators Dilemma comes up from the bottom [Harvard
prof Clayton Christensens 1997 book of that title argues that disruptive
technologies often start out less capable than the entrenched technology]. Youve
got the performance of the current technology as a function of its cost; the
examples he gives are of things that are simpler; they perform less well because
the mainstream technology has gotten to the point where it is offering an attribute
package beyond what most customers really need, so it opens up this window for
things to come in underneath. Youve got to think about what were
doing as coming from the top down. Coming from above. Offering a combination
of capabilities on a vehicle that are better than todays vehicle at a
lower cost. Thats where the difference lies.
Why do I say better? A fuel cell propulsion systemone tenth
as many moving parts as an internal combustion engine propulsion system. Thats
a huge deal in the Clayton Christensen context because this is a much simpler
device from a mechanical perspective. Each moving part that you have in a system
tends to have to be precisely formed, machined, hardened, lubricated because
theyre moving relative to each other. If you can get an order of magnitude
reduction in all of that, that simplifies everything. The parts were talking
about are very simple geometry. You look at the shape of a piston and the bowl
we machine to optimize the combustion process, thats sophisticated geometry.
That goes away. Furthermore, you dont need a separate plant for four-,
six-, and eight-cylinder gas or diesel like we do today. You can do all this
in one facility. There are huge enablers for simplifying the design of the vehicle.
Then you put the electronics in place of a lot of the mechanical controls. Youve
got to do that in such a way that you dont have redundant mechanical controlsby-wire
systems arent going to mean anything to the industry if you have to have
a back-up mechanical systemthats going to add costs. Weve
got to get to the fault-tolerant electrical architectures and other things that
allow us to not need a redundant mechanical system. When you put it in the Innovators
Dilemma context, were not asking our customers to drive a product that
offers them less value, that offers less capability. Were, in fact, thinking
about a car that is more fun to drive and simultaneously safer to drive and
simultaneously environmentally benign and dramatically more energy efficient.
We want to give something thats better. And thats different than
what the Innovators Dilemma is about. We want to do something thats
better at equal or better cost performance.
Better performance comes from the electric drivethe maximum torque instantly.
The ability to get the wheel motors and control each wheel from a braking, steering
and accelerating standpoint. Youre controlling each wheel separately.
Some people say were solving a problem that doesnt exist or answering
a question that hasnt been asked. I think theres going to be dramatic
excitement around a driving experience that comes from having the ultimate control
from a chassis perspective. You take each corner of the vehicle and youre
managing the traction and the braking and the torque and the suspension aspects.
Take things like MagneRidefive times faster response with respect to road
motions. Combine that with the controls of the steering, braking and accelerating
in each corner of the vehicleplus the inherent simplicity: Electric motors
are commodities, not something that has to be invented.
It absolutely obsoletes the conventional automobile if were right, and
if we can get to those cost goals. Thats why Wagoner [G. Richard Wagoner:
GM chairman and CEO] is driving us like mad to $50/kW. I dont even think
about this technology in terms of bringing it to market at a higher cost.
On the Hybrid Market
This market has not exploded in size. Weve got to be really honest with
how many hybrids are being sold out there. Its not like anyone has run
away with hundreds of thousands of units of sales that other competitors are
missing out on because Toyota and Honda have put hybrids in the market. The
35,000 units sold in 2003 were just 0.2 of 1% of the 17 million unit market
in the U.S. What is there to be concerned about? The thing you should be concerned
about is knowledge, know-how, capability, and supply base. Having that knowledge
in our Allison Buswhich also is a key part of the story: our 235 buses
that we sold to King County [Washington] this year will save as much fuel as
8,000 Priuses. The bus garage operators love the bus because of the fuel savings,
the lower wear-and-tear on brakes, lower peak operating cycles on the diesel
engines, fewer oil changesall real pluses for the bus operators and customers.
We have that knowledge in our company. Weve transferred that into our
advanced Hybrid System 2, which will be the basis of the [07] Tahoe and
the Yukon. This system fits right within the footprint of our six-speed transmission.
Any vehicle that GM has that has this six-speed transmission could have this
hybrid system available on it. It doesnt have to marry up with a purpose-built
engine or architecture like the Prius.
I give Toyota and Honda full credit for what theyve done. It took a lot
of courage and technical know how to get their products where they are, but
this perception that GM is out of this game on hybrids is a misplaced assumption
because were selling one now, the bus plus the pickup truck, and well
add to that the Saturn Vue and Malibu as belt-alternator starter systems with
12-15% fuel economy improvements. The real big question is: How big is this
market?
Please dont count us out of the game on hybrids. Youre going to
see some impressive hybrid technology from us. And were doing it because
there may be a market there. Were doing it because were the worlds
largest auto company and we need to be in a leadership position on the technology.
Were also doing this because we dont want this to be a one-horse
race. Also, we dont want people to conclude that this is a one-technology
race relative to advanced propulsion because theres a lot of impressive
stuff going on to improve gas and diesel engines and longer term on fuel cells
and hybrids.
ON WHY HYDROGEN-POWERED VEHICLES MATTER
Our strategy is simple. Hydrogen gives us a solution to 99% dependence on petroleum
for personal transportation. The auto industry should not be held hostage to
the petroleum industry, and petroleum as an energy pathway. Thats being
pretty myopic. If you bet the future of this industry on petroleum, I think
its too risky in todays world. You need alternatives in addition
to petroleum. And if you can make the cars more exciting, and simpler and easier
to build, with more design flexibilitygee, that feels like the win-win
that were seeking. The key to making that a reality is the $50/kW, 5,000
hours of durability, and 300 miles range.
