challengex Challenge X

Background

In the first decade of the new millennium, the American automotive customer market trended toward larger family-sized vehicles. At the same time, an increased need to reduce energy consumption, as well as decreased vehicle emissions, was becoming imperative. As a result, the automotive and electronics industries, the U.S. and Canadian governments, and the academic community worked together to launch Challenge X: Crossover to Sustainable Mobility.

Innovations & Highlights

The teams in Challenge X employed many novel ideas, approaches, and technologies that (1) provided near-term and long-term solutions to significantly reduce well-to-wheel energy consumption, (2) reduce petroleum energy consumption and emissions, (3) significantly reduce criteria tailpipe and GHG emissions, and (4) increase pump-to-wheel fuel economy. All of the teams selected hybrid vehicle designs for their student-modified vehicles, spanning the gamut of parallel, through-the-road, and series hybrid electric vehicle. These vehicles employed state-of-the-art nickel metal-hydride and lithium-ion battery packs. A variety of advanced electric drive systems employed by the teams enabled the hybrid electric vehicle features, such as regenerative braking, high-load electric assist, and engine transient smoothing. Engine selections were dominated by highly efficient diesels and turbocharged spark-ignited engines operating on biofuels such as ethanol and biodiesel. More advanced engines, such as highly diluted and boosted spark-ignition engines and hydrogen-assisted ultra-lean burn combustion strategies were also used. Highlights:
