Vehicle Technology
Advanced Vehicle Technology Competitions for Students
Since 1987, the U.S. Department of Energy (DOE) has sponsored more than 45 advanced vehicle technology competitions through Argonne National Laboratory. These competitions represent a unique coalition of government, industry and academic partners who have joined forces to explore sustainable vehicle solutions. Argonne organizes and operates these competitions to
- Accelerate the development and demonstration of technologies of interest to DOE and the automotive industry
- Provide the automotive industry with a new generation of engineering leaders with highly desirable experience
- Help prepare the market to accept advanced vehicle technologies.

Mississippi State University's vehicle won first place in the competition.
Focusing on graduate and undergraduate engineering students, these competitions target ultra-efficient vehicle designs, hybrid electric vehicles, and alternative fuel vehicles for development, demonstration, and testing. They emphasize current or future vehicle technology; students work with production vehicles (donated by vehicle manufacturers) to improve their energy efficiency and to meet the toughest emissions standards while maintaining performance and functionality. Extensive data are collected to measure the real-world performance of advanced technologies and benchmark their developmental status.
The competitions represent a unique coalition of government and industry aimed at eliminating technical and institutional barriers to acceptance of advanced vehicle technologies and alternative fuels. The competitions are highly valued and supported by automotive manufacturers, suppliers, fuel providers, and the educational community. Auto industry experts judge events, interact with students, and compare technologies. Federal funding for the competitions is heavily leveraged by industry contributions.
Conducting competitions provides significant technical, educational, and promotional benefits to DOE and the nation. More than 16,000 students from more than 600 institutions from the United States, Canada, and Mexico have participated, gaining real-world, hands-on experience tackling the challenges associated with building more fuel-efficient vehicles.
The competitions continue to grow in sophistication and complexity. Both Ford and General Motors have made a commitment to long-term support for these competitions on the basis of their benefits in technology development and demonstration.

Vehicle
A vehicle (Latin: vehiculum) is a mechanical means of conveyance, a carriage or transport. Most often they are manufactured (e.g. bicycles, cars, motorcycles, trains, ships,boats, and aircraft), although some other means of transportwhich are not made by humans also may be called vehicles; examples include icebergs and floating tree trunks.
Vehicles may be propelled or pulled by engines or animalsincluding humans, for instance, a chariot, a stagecoach, a mule-drawn barge, an ox-cart or rickshaw. However, animals on their own, though used as a means of transport, are not called vehicles, but rather beasts of burden or draft animals. This distinction includes humans carrying another human, for example a child or a disabled person. Means of transport without a vehicle or animal would include walking, running, crawling, or swimming.
Vehicles that do not travel on land often are called craft, such as watercraft, sailcraft, aircraft,hovercraft, and spacecraft
Land vehicles are classified broadly by what is used to apply steering and drive forces against the ground: wheeled, tracked, railed, or skied.
Types of vehicles
[edit]Bicycle
- see Bicycles (see also Vehicular Cycling)
- see main article History of the bicycle
[edit]Rickshaw
A rickshaw is a vehicle that may carry a human and be powered by a human, but it is the mechanical form or cart that is powered by the human that is labeled as the vehicle. For some human-powered vehicles the human providing the power is labeled as a driver.
[edit]Tricycle
- see Tricycle
[edit]Quadracycle
[edit]Velomobile
- see Velomobile
[edit]Electric road carriages
[edit]Steam road carriage
- see steam car
[edit]Steam tricycle
- See steam tricycle
At the other end of the scale, much lighter steam vehicles have been constructed such as the steam tricycle from the Comte de Dion in 1887.
[edit]Petroleum (gasoline / diesel) motor-carriages
- See Benz Patent Motorwagen
- See Ford's model T
- See Automobile
[edit]Road trains
A road train consists of a conventional heavy truck pulling three trailers or more, used in rural areas of Australia to move bulky loads such as livestock efficiently.
