Over the last 25 years, automation technology has become an essential part of automobile assembly plants. A typical assembly plant uses several hundred robots to build and paint the vehicle frame. 2 While robotic technology continues to grow in assembly plants, the technology does have limitations, especially in performing more delicate tasks. The advent of Intelligent Assist Devices, in particular Cobots (Collaboratiave robots), aided in reducing ergonomic concerns, while also improving safety, quality and productivity. Cobots, developed by Northwestern University and General Motors Corporation, are designed to work in collaboration with human operators to move objects and perform physically demanding tasks on vehicle assembly lines.
Automobile manufacturing firms compete based on a set of established commercial practices which are conveyed in business and industrial engineering literature.3 These practices make up the process of automobile manufacturing, which are depicted in the following list of elements:
Elements of Automobile Manufacturing

|Durability ||Workforce and Organization|
|Product Development||Logistics and Supply Chain|
|Process Development ||Research and Engineering|
In looking at trends in global automobile manufacturing, Japanese automakers have been leaders in stream-lined manufacturing process systems. These methods have been adopted by manufacturing plants worldwide. These efforts were pursued in order to increase productivity and product quality. U.S. and European automakers initially showed considerable gaps in manufacturing plant productivity, however the gap in productivity with Japanese automakers' assembly plants have been narrowed substantially in the last several years.

Automobile Technology & Innovation
The product life-cycle for automobiles continues to shorten due to competitive market pressures. Competitive market forces have caused automakers to dramatically redesign car models every four to five years.4
New technological developments have led to unique and innovative designs for future automobiles. Automobile manufacturers use the development of new technologies to enhance performance capability, as well as to create innovative designs. Alternative fuel technologies, such as electric hybrids and fuel cell cars, have received considerable attention, and demonstrate attempts to design vehicles that are more energy efficient and greatly reduce engine propulsion reliance upon fossil fuels.
Electric Powered Vehicles
The movement towards electric powered vehicles began as a result of the 1973 Oil Embargo, in which efforts were made to utilize electric battery technology to power engine propulsion. However, problems and limitations regarding driving range, speed and a very small market, all led to automakers GM, Ford, Honda and Toyota discontinuing their electric vehicle programs during the late 1990's.
Hybrid vehicles combine two or more sources of power, which are able to operate using a rechargeable battery and gasoline. Production of gas-electric hybrids signifies the first significant move away from total reliance on the internal-combustion engine in nearly a century.5
Hybrid vehicles are highly fuel efficient and presents the first major step toward fuel cell vehicles, according to industry specialists. Japanese automaker Toyota, is one of the auto industries leaders in hybrid vehicle research and production with its Prius model. General Motors, also involved in producing hybrid vehicles, will be introducing and mass producing its hybrid model by 2007.6 Most major automakers plan to introduce hybrid vehicles to the market within the next five years.
Fuel Cell Vehicles
Another automobile technology that is presently viewed as the latest catalyst in future automobile technology, is fuel cell powered vehicles, in particular hydrogen fuel cell powered engines. Fuel cell systems operate by compressing hydrogen made from natural gas and gasoline, which is then converted to hydrogen by on-board systems. 7
Automakers and suppliers worldwide are investing substantially in the development of fuel cell systems. General Motors (GM), Ford and DaimlerChrysler have invested billions of dollars in a collaborative project to develop hydrogen fuel cell technology. GM is perhaps the most active in investing, as well as researching and developing fuel cell technology. However, many industry specialists indicate that fuel cell technology will not be available on the commercial market until the next 10 to 15 years.
There are, however, problems associated with hydrogen fuel systems which consist of:
Fuel cell vehicles will be more expensive
Fuel cell cars will require a new infrastructure for vehicle manufacturing and maintenance
Developing a system for producing and distributing hydrogen fuel
Many uncertainties remain regarding the development and use of hydrogen fuel cell technology, as well as addressing the major question on how to create a viable infrastructure that supports the use of fuel cell vehicles.
Advanced Product Design and Vehicle Operating Systems
Modern automobiles are increasingly relying upon more advanced electronics, computer, and wireless communication systems to assist drivers and enhance safety. These technologies replace mechanical systems that power, steer and brake the vehicle. Most vehicles have several computers, with high-end models having a half dozen or more that control functions, which range from shifting gears to operating GPS navigational systems.8
GM has introduced the Autonomy concept model, which uses hydrogen fuel cell technology that powers electric motors in each wheel. The vehicle uses a chassis and replaceable body, allowing greater flexibility and freedom in designing the interior. Internally, the vehicle operates without pedals or dashboard, using sophisticated computer and electronic systems to operate the vehicle.
Voice activation is another technology being developed for use in future vehicles. Voice activation systems are expected to operate internal climate controls, open doors, and respond to navigational request by the driver.
The next step in automobile electronic and communications technology is vehicle sensor technology. Sensor technologies use radar or laser technology to control systems that detect vehicles in front which then automatically slow down the vehicle. Companies are using sensor technology to serve as collision-avoidance systems that operate and control vehicle safety systems and on-board equipment.
