Competition details

Challenge X is a continuation of the long history of student vehicle competitions sponsored by the DOE since 1987 (Challenge X a). The majority of the competitions involve high level sponsors from both the government and the automotive industry. Challenge X is the latest in these series of competitions. The goal of the competition is to guide students through the engineering design process used at many automotive manufacturers, while developing and exploring various advanced technologies which can be used to reduce energy consumption and vehicle emissions. The vice president for GM's Powertrain Division, Tom Stephens described the competition by saying:
This is the first time that a student competition has emphasized the importance of fuel choice in achieving sustainability mobility. Challenge X provides the student teams an opportunity to take an open-minded well-to-wheels approach to all the issues involved in energy efficiency and emissions – including the fuel source, the propulsion system and the vehicle's real world utility and consumer appeal (Foster).

When applied properly these technologies lead to more sustainable vehicle solutions. As automotive consumers have increasingly purchased large family sized sport utility vehicles over the past decade, the competition vehicle for Challenge X is the Chevrolet Equinox

The second generation Equinox was announced by GM on December 21, 2008, and debuted at the 2009 North American International Auto Show in Detroit. The 2010 Equinox went on sale in June 2009.

 . Student teams are required to maintain the stock vehicle's performance, safety, utility, and consumer acceptability all while attempting to increase its fuel economy and decrease its emissions.

Year One

During the first year of the competition each team focused on vehicle simulation, computerized powertrain simulations, and the ever-present engineering give and take present in early vehicle design. This intensive modeling of each teams proposed vehicle architecture is designed to guide the teams in making decisions about vehicle hardware and components. For example, students must compare the advantages and disadvantages of many components that are able to perform the same function, and when students find that there is not an existing component available to perform a specified function, they must determine if they have to time and/or resources to develop such a component. At the end of the 2004 – 2005 academic year, the first years competition was held in Milford, Michigan

Year Two

The second year of the competition was focused on teams implementing their chosen architecture into their project vehicle. After completing year one, each team was required to continue with their proposed architecture and any major changes to their design, or to the vehicle structure or safety systems had to be approved through a detailed waiver process where the reasons for and ability to make such changes while meeting competition goals are explained to competition organizers. Vehicle integration was the main focus of year two, where teams were required to have a working vehicle by the time of the year end competition. A strong focus was placed on powertrain development and a demonstration of energy use and emissions goals as defined by each team in their year one reports. Each team was also judged extensively on vehicle performance categories such as greenhouse gas impact, total well-to-wheels fuel economy, emissions, towing capacity, acceleration, off-road performance, and consumer acceptability. Furthermore, each team was required to submit a technical paper and perform an oral presentation (Challenge X d).

Year Three

Year Three required further refinement of the vehicle with the goal of delivering a “showroom” vehicle that addresses the requirements of consumers. At the conclusion of years one through three, team vehicles were judged in areas such as towing capacity, acceleration, ride and handling, noise and vibration, greenhouse gas impact, total well-to-wheels fuel economy, and consumer acceptability.

Year Four

The competition is currently in year four for the 2007-2008 academic year. The fourth year of the program will give students the opportunity to further implement innovative technologies in their vehicles, such as telematics, that will help meet consumer demands for safety, security and convenience. The final year will also allow teams to focus on developing and implementing marketing plans for their vehicles to promote the goals of the Challenge X program. The year end competition will be a road rally.
