EcoCAR: The NeXt Challenge is a three year Advanced Vehicle Technology Competition series organized by Argonne National Lab (ANL), and sponsored by General Motors and the U.S. Department of Energy. University teams are challenged to design and build a crossover SUV powertrain to improve fuel economy, reduce petroleum energy use and well-to-wheel greenhouse gas emissions, while maintaining safety, performance, and consumer appeal. Many of the 16 teams selected a plug-in hybrid electric vehicle (PHEV) powertrain design in 2009 Year One, and built a vehicle for the 2010 Year Two competition held in Yuma, AZ. The third and final 2011 Year 3 competition was held in Milford, MI where the vehicles were subjected to a series of on-road tests to measure emissions and energy consumption, acceleration and braking performance, handling, and static and dynamic consumer acceptability. The competition requires participating teams to re-engineer a stock crossover utility vehicle donated by GM. The result of this design process was an Extended Range Electric Vehicle (EREV) which uses grid electric energy and E85 fuel for propulsion. The vehicle achieved an SAE J1711 utility factor corrected fuel consumption of 2.9 L(ge)/100 km (82 mpgge) with an all-electric range of 87 km (54 miles). Using corn-based E85 fuel, the well-to-wheels petroleum energy use (WTW PEU) and greenhouse gas emissions (GHG) were reduced by 91 % and 18 % respectively when compared to the stock 4-cylinder, gasoline-fueled vehicle. This paper will give a brief overview of some of the supervisory control strategy employed and detail the on-road vehicle testing performed during the Year 3 EcoCAR 2011 competition that was held at GM's proving grounds in Milford, MI. Data from this testing will show the effectiveness of the control strategy in reducing emissions and energy consumption compared to the stock vehicle.
