bottom surface is the base of the vehicle. It is painted a dark gray and helps to emphasize the glossier layer. Much of
the hydrogen fueling system, including its four tanks, is beneath this surface.
- The middle layer is the floor, which has
a semi-gloss appearance. Nicknamed 'the magic carpet' by the designers, it flows from the top of the instrument panel, down
the footwell over the hydrogen storage tanks and all the way to the tailgate. Through it run the main three slots.

Chairman and CEO, Ford Motor Company
Building on the heritage started with the Model T, Ford's Model U concept begins Ford Motor Company's second century of
Equipped with an array of upgradable technologies and a multi-function tailgate, Model U can stick
with you and adapt to your needs if your life changes.
Powered by the world's first supercharged hydrogen internal
combustion engine, equipped with a hybrid electric transmission and pioneering green materials and processes, Model U is a
vision for the future. It is Ford's model for change – exploring the benefits a vehicle provides to its users, the way it
is manufactured and how it impacts the world.
It is the Model T of the 21st century.
Inspired by how the Model
T revolutionized personal transportation in the last century, a team of Ford researchers and designers created Model U. It
is a clear expression of Ford Motor Company's strategy to pursue future automotive technologies without compromising today's
customer expectations for personal mobility. It is a car designed to be good to you and good for the world.
Henry Ford built the Model T, it was affordable, offered the most advanced manufacturing and was built with the most advanced
materials,” says Dr. Gerhard Schmidt, Ford Motor Company vice president of Research and Advanced Engineering. “In a similar
but entirely contemporary way, Model U starts a new cycle. Emissions, safety and fuel economy, also green materials and
processes, are all key questions facing the entire industry. We believe the Model U addresses them all.”
was struck among Ford's Research and Advanced Engineering, Ford's Brand Imaging Group (an internal design think tank), Bill
McDonough (architect of the new Rouge Center and co-founder, with Dr. Michael Braungart, of the product design firm MBDC), BP
and a host of technology suppliers.
“Model U is very different from most futuristic concept vehicles,” says J Mays,
vice president of Design. “It tries to address the challenges of the future and proposes exciting, realistic solutions that
exceed current industry standards. Therefore, I hope it does justice to the name 'Model for Change.'”
Model U offers
SUV driving excitement that is affordable, but can grow with a customer's lifestyle and aspirations. It is designed for mass
production, but has nearly infinite capacity for being personalized and upgraded. It offers advanced technologies that respond
to customers' desires for convenience, entertainment and continuously improved safety. And it looks at how building a car, truck
or SUV can strengthen the environment.
“What I think is so exciting about Model U is that it opens the door to a whole new
way of looking at things, just like the Model T did,” says McDonough. “The vision behind Model U is entirely positive. Instead of
focusing on minimizing environmental harm, which is what most approaches to sustainable mobility do, Model U starts to find ways
to be re-creational and regenerative – to have fun and create environmental benefits at the same time. That's a totally new vision
for the auto industry.”
Reconfigurable Interior and Exterior Designs
The Model U fits Ford's Outfitters
image with its flexible design that can adapt to meet any individual's needs and perform any type of function. Its design is
determined and confident, accentuated by a tough stance and pronounced wheel arches. With seating for up to four people, lots
of storage space and built-in flexibility, it provides sensible solutions in an innovative way.
“This project was
very exciting for us,” says Laurens van den Acker, chief designer for the Model U. “To embody the spirit of the Model T, we had
to design an extremely ingenious car that could grow with your needs and meet an incredible packaging challenge. Model U doesn't
compromise interior space for the occupants or cargo despite the storage space needed for the hydrogen tanks and the hybrid
The Model U's unique 3-box profile exterior has a tough modular look. Body panels
are visually separated through different finishes and are made of different materials. The body side has a glossy appearance; the
doors are matte and grooved for both design appearance and structural integrity. The body structure is aluminum; the front side
panels are built with a natural fiber-filled composite material.
Its flexibility makes it capable of performing rugged
jobs as well as driving to an evening out. It provides different driving experiences with one vehicle. Model U goes from
completely closed to completely open. When completely open, it looks like a pickup. The rear seats can be removed to provide
a longer loading floor.
The roof of the Model U is a power-retractable canvas soft top that opens rearward to offer a
nearly open-air motoring experience. The rear of the vehicle also can be opened with power controls. The rear window folds
into the deck lid and the deck lid then folds back and down into the floor so that it is hidden and safe from being damaged.
The Model U also features a power hood that opens from the windshield toward the front of the SUV. The hinges are hidden
in the front bumper.
The interior of the Model U is uncluttered and open, but allows for
flexibility through the use of the innovative slot system. It is shown as an affordable base vehicle that grows with a customer's
life and aspirations. The Model U ties back to the Model T roots in that it is classless and allows people to be aspire to
something more, yet it delivers for the people who can already afford more.
An important feature of Model U is the
'layering' of major design elements. This is done to visually and physically separate the materials from each other, a vital
aspect when designing for disassembly.
There are three basic layers that make up the interior:
Model U comes with wireless capability.
The steering wheel is located in the first slot and is equipped with two controls. One operates voice controls and the other
is a scroll wheel that lets the driver control fan speed and volume of the entertainment system. These buttons are repeated on
the armrests in both the front and rear rows. The basic dash has analog dials, but they can be upgraded to digital.
The pedals are stationary, but the gear shifter is a wireless device that can be located between the seats or directed to
The passenger side is an open space perfect for customization. An owner can choose to place a second screen
there or use the space for storage. Accessories, seats and storage bins could be left inside or moved in and out as needed.
Rear seats are located on slots and can be moved forward to offer more rear space or removed to create the pickup bed.
Rear-seat passengers will have small entertainment screens in front of them. Slots allow them to plug in DVD, computer or
The three main slots end several inches behind the second row of seats to provide enough space for
attachments. Additional slots, located in the doors, can hold armrests, wireless switches or any other accessory.
Finally, small slots are located in the roof for placement of the rearview mirror, sun visors and microphones for the
speech system. These slots also are the design element of modular technology that is central to Model U's functionality.
The slot system allows the “U-ser” to take personal accessories to other vehicles, or dealers to very quickly update
the look of the car when it enters the used-car market.
Hydrogen Internal-Combustion Engine
Model U is powered by internal combustion engine (ICE) that is optimized to run on hydrogen. The engine is supercharged
and intercooled for maximum efficiency, power and range. Its emission of all pollutants, including carbon dioxide, is nearly
zero, and the engine is up to 25 percent more fuel-efficient than gasoline engines. A hybrid-electric transmission system
further improves efficiency.
“We believe that hydrogen will be the automotive fuel of the future,” says Dr. Schmidt.
“The hydrogen ICE can act as a stepping stone to hydrogen-fueled mass transportation that eventually will incorporate fuel cells.”
The hydrogen ICE is a common-sense powerplant that uses existing, proven technologies to deliver the environmental benefits of
a hydrogen fuel cell – but at a fraction of the complexity and cost.
The hydrogen ICE is based on Ford's global 2.3-liter
I-4 engine used in the Ford Ranger, the European Ford Mondeo and a number of Mazda vehicles. The engine is optimized to burn hydrogen
with 12.2:1 high-compression pistons, fuel injectors designed to handle hydrogen gas, a coil-on-plug ignition system, an electronic
throttle and new engine management software.
Because hydrogen has a very wide combustion range (from 4 to 75 percent),
hydrogen-fueled engines are able to use a wider range of air/fuel mixtures than gasoline engines, and can be run in the fuel-efficient
“lean” regime without the complications of pre-ignition or “knock.” Much like a diesel engine, the hydrogen ICE runs unthrottled while
under way, with air/fuel mixtures as lean as 86:1 during highway cruise, compared to the 14.7:1 of gasoline-powered vehicles. It
can reach an overall efficiency of 38 percent, which is approximately 25 percent better than a gasoline engine.
are no carbon atoms in the fuel, combustion of hydrogen produces no hydrocarbon or carbon-dioxide emissions. Even without
aftertreatment, oxides of nitrogen (NOX) are very low, and catalyst research may soon reduce tailpipe output of potentially smog-forming
emission to below ambient conditions in many cities.
Designing a gasoline engine to burn hydrogen fuel has typically resulted
in significantly lower power output – until now. Ford researchers have shown that with supercharging, the hydrogen ICE can deliver
the same power as its gasoline counterpart and still provide near-zero-emissions performance and high fuel economy. The centrifugal-type
supercharger provides nearly 15 pounds per square inch (psi) of boost on demand.
Also, Model U uses a novel dual-stage
intercooling process. After leaving the supercharger, the intake air passes through a conventional air-to-air intercooler, then
through an air conditioning-to-air intercooler for a further reduction in temperature. This patent-pending solution further improves
the performance of the engine.
Ford Modular Hybrid Transmission System
The hydrogen ICE is joined with
an advanced hybrid electric transmission technology called the Ford Modular Hybrid Transmission System (MHTS). The torque converter
from a conventional transmission is replaced with a high-voltage electric motor and two hydraulic clutches that permit the motor to
operate independently of, or in concert with, the engine.
The electric motor simultaneously fills the role of flywheel, starter,
alternator and hybrid traction motor.
The hybrid system is known as a “parallel” arrangement, which means that Model U can
operate on either the hydrogen ICE engine or electric motor, or both for extra power. A regenerative braking function reclaims energy
that would otherwise be lost as heat, storing it in the 300-volt, air-cooled battery pack for the next acceleration, passing
maneuver or hill climb.
When the driver comes to rest at a traffic light, the engine can automatically be switched off
to save fuel. When the accelerator is applied, the electric motor instantly starts the engine, the clutch to the transmission
engages, and the vehicle begins to pull away, all within 300 milliseconds.
MHTS provides significant increased fuel
efficiency while delivering familiar performance and drive characteristics. The technology is designed with minimal effect on
the base transmission so as to reduce complexity and cost compared to other hybrid systems.
Model U can carry up to 7 kilograms of hydrogen on board. Its fuel tanks, made of a 3-millimeter aluminum pressure barrier
with a carbon-fiber structural casing, are rated to an operating pressure of more than 10,000 psi.
Hydrogen offers the
potential for a sustainable, cleaner burning fuel. Ford Motor Company, in conjunction with BP, is exploring the potential for
hydrogen production. BP currently produces hydrogen from natural gas, in an efficient, effective manner. Continued support from
industry and government, through FreedomCAR and other efforts, might one day make its use a reality in vehicles like Model U.
Conversational Speech Interface
Along with being personalized from a physical feature and capability aspect,
the Model U is also a more intelligent vehicle that allows you to use technology for personalization and convenience.
challenge we face is having our vehicle technology keep pace with electronics developments; we believe we have a solution,” says
Bryan Goodman, Technical Specialist in Ford's Research and Advanced Enginering. “The BluetoothTM-enabled slot system
allows for continuous additions and upgrades throughout the life of the vehicle.”
In 1999, Ford Motor Company introduced
the industry's first full-featured vehicle voice control system called JaguarVoice. This system enables control of a limited set
of vehicle features using very precise spoken commands. It remains the best system in production today.
With the Model U,
Ford is bringing voice recognition technology to an amazing new level. Advanced conversational speech interface technology
simplifies the control of many functions by allowing you to have a normal dialogue with your vehicle. A text-to-speech system is
used, but will sound like a real person rather than a robot. Specific commands don't have to be memorized. The voice system
controls navigation, phone, entertainment, climate control, the retractable roof, and personalization preferences.
Conversational speech interface allows you to use everyday language and flexible voice commands. If there is any ambiguity in
what a driver or passenger is asking for, the system will ask for more information in very simple language. For example, if an
occupant asks the Model U to “Call Steve Smith,” and the system finds several numbers for Steve Smith in the address book, it will
list them and ask which one should be dialed. If asked to play music, Model U will ask what type and then list the artists
available. Music is stored in MP3 format, and is downloaded through wireless technology from a PDA or a home computer.
A clear advantage can be found in using the navigation system. Current systems require a person to either type in a location
or spell it out letter-by-letter, number-by-number. You can simply tell the Model U a specific address, major intersection or one
of many points of interest, and it will guide you to your destination in conversational terms.
For climate control, the
driver or front passenger can ask the Model U for different temperature settings, fan speeds or locations, such as the defrost
The conversational speech interface has a vocabulary of over 50,000 words so far, and speaks only when spoken to.
Model U's system can be used to configure different drivers' personalized settings – including the type of voice, the graphic
style of the visual interface and even favorite music.
The BluetoothTM technology enabling the system to work
is located within the controls of the Model U. It works with any BluetoothTM-enabled cellular phone or PDA, provided
the device is turned on and is located somewhere inside the vehicle. It can be inside an occupant's pocket or a purse. This
allows occupants to connect with all their personal files, including phone lists and Internet addresses. The Model U and
individual personal electronics are automatically synchronized when entering the vehicle.
Improved Driver Visibility
and Awareness through Active Safety
The Model U offers several technologies designed to improve awareness – for both
the driver and the vehicle itself. The goal is to enhance a driver's natural abilities and supplement them with the vehicle's
ability to recognize a potential driving risk.
Four technologies in the Model U are designed to address these issues:
With Adaptive Front Lighting, the goal is to change the area
being lit depending on the driving environment. For example, at an intersection broader coverage is needed than when a vehicle
is going straight at a constant speed. Then a narrow, but more distant area needs to be covered. The system uses vehicle inputs,
speed, steering wheel angle and turn indicator position, plus global positioning satellites and digital mapping to constantly know
where the Model U is located and what beam pattern is needed for safe driving.
An advanced Active Night Vision system on the
Model U will allow the driver to see well beyond the range of low-beam headlights during nighttime driving without affecting drivers
in oncoming vehicles.
The system uses a near-infrared (NIR) diode laser, compact optics, a sensitive CCD camera and a
heads-up display. The NIR light is invisible to the human eye, so the laser is used to illuminate the roadway with a high-beam
pattern at all times without blinding oncoming drivers. Natural-looking video images that include lane markings and signs are
shown on the heads-up display directly below the driver's view of the roadway.
Another technology on Model U is designed to
help determine if collision threats exist. Pre-crash sensing technology uses a forward-looking stereo camera system. A pair of
cameras detects if a vehicle is in front of Model U. The system then processes the image to classify what type of vehicle it is and
assess the potential collision threat. At that point, information is sent to the driver and appropriate safety technologies can be
Vehicle classification is an emerging technology that is key to accident avoidance systems. Countermeasures
could differ depending on the specific danger.
around large vehicles. Unique to Ford, Traffic ViewTM enables the driver to see problems up ahead without placing the
vehicle in a dangerous situation. For example, left turns at an intersection can be a challenge if vehicles waiting to turn on the
other side of the intersection block the driver's view of through traffic. With TrafficViewTM the driver can see if
vehicles are approaching safely and make the turn decision with more information.
Model U also has four-point safety belts
in all seating locations for improved protection of occupants in the case of a collision.
Green Materials and Processes
The Model U is a realistic approach to the future, guided by a powerful, positive vision. It follows the traditions of
the Model T by being designed for the masses and addressing social issues, specifically environmental concerns. The Model U represents
how using and producing personal transportation can have a positive effect on the planet instead of simply minimizing negative
“Model U takes a positive approach to its materials and manufacturing,” says David Wagner, Model U's technology
project manager. “Some of these concepts won't come to fruition for years to come, but this is an important first step. Examples
can be found all around the vehicle, inside and out.”
The Model U is helping encourage development of materials that are safe
to produce, use and recycle over and over again in a cradle-to-cradle cycle. These materials never become waste, but instead are
nutrients that either feed healthy soil or the manufacturing processes without moving down the value chain.
polyester is the fabric designed by Milliken and Co. to be a technical nutrient. It can be recycled into base elements and
reprocessed into material fiber again and again without losing any performance qualities, and it is made from healthy substances.
This polyester is used inside the Model U on its seats, dash, steering wheel, headrests, door trim and armrests.
U also uses a potential “biological nutrient” made to safely return to the soil to feed the next generation of resource growth called
polylactide or PLA. It is a biopolymer from Cargill Dow derived from corn. PLA fabrics, derived from Interface, are used for the
Model U's canvas roof and carpet mats. The fabric has the comfort and feel of natural fibers while having the performance and easy
care of synthetics that are petroleum based.
Because cradle-to-cradle materials (technical and biological nutrients) aren't
available in all cases, other materials are used in Model U to lighten its environmental impact. Renewable, plant-based components
are used in several cases to replace petroleum-based materials.
Rubber tires use corn-based fillers as a partial substitute
for carbon black. They offer lower rolling resistance and lower weight, leading to improved fuel economy and improved traction on
There are also several soy-based components in Model U, including polyurethane seating foam and polyester resin
that is reinforced with fiberglass and used to make the tailgate.
In conjunction with Model U, the team from the Ford Research
and Advanced Engineering is working with Shell Global Solutions to test a bio-based lubricant from sunflower seeds. The Model U
also begins to address manufacturing issues trying to develop flexible manufacturing processes that reduce energy use and parts
complexity, as well as develop technical processes that have a positive environmental impact.
Flexible manufacturing plays
a role in allowing easy reconfiguration of a vehicle in the future. Various types of vehicle body architectures can be constructed
with common nodes and common extruded tubes joined with low energy-efficient methods. This could also allow many different vehicles
to be built in a single assembly plant with reduced inventory and lower tooling cost.
This type of efficiency is also expressed
in the interior of the Model U. The armrests on all four doors are exactly the same, as are the center armrests in the front and
rear seating rows. This modularity begins to facilitate the recovery of the cradle-to-cradle materials as Model U is dismantled,
assuring highest-quality recycling of these valuable substances.
Environmental concerns in manufacturing are also addressed
with a new UV-cure clearcoat system developed by Akzo Nobel. Clearcoat is the topmost layer of a vehicle's paint. It gives a
vehicle its shine and protects the paint from damage. During the clearcoat cure, the Model U was exposed to ultraviolet light rather
than to the high temperatures that are used traditionally.
This system provides a harder finish and means the Model U will
be more resistant to scratches than most cars and trucks. The process eliminates the need for a bake oven and uses less energy and
solvents than traditional systems.
