With seven E85, six B20 biodiesel, two H2 fuel cell, and one full-electric vehicle at the Year Two Finals, the contest was fierce as each team showcased their unique vehicle architecture and competed for the first place trophy.
In the end, Mississippi State University took top honors with their plug-in series hybrid. The team won more than 15 awards during the Year Two Competition Finals, including 1st place in Energy Storage Design, 1st place in Outreach, 1st place in every Emissions and Energy Consumption event, and had the Best Controls, Mechanical, and Vehicle Design Review presentations.
In Year Two, the Mississippi team integrated a variety of components into their vehicle to decrease emissions and maintain consumer acceptability. The team’s plug-in range-extended hybrid included a well designed, translucent energy storage system cover with an inventive liquid cooling system. They had an innovative high-voltage wire routing, urea injection system, and maintained stock cargo space. They even bettered the baseline vehicle by more than two seconds in the Autocross Event.
MSU also won every dynamic event in the Emission and Energy Consumption category. For the first time in Advanced Vehicle Technology Competition history, the Mississippi team received the highest fuel consumption score. The team utilized more than 90 percent of their 21 kWh battery pack and finished both the 22 mile and 44 mile schedule without using any biodiesel. The team was also able to significantly reduce their petroleum use by charge depleting for 60 miles and bettered the baseline vehicle’s greenhouse gas score by more than 30 percent in the Well-to-Wheel Greenhouse Gases event. In the end, Mississippi State achieved Tier 2, Bin 7 emissions over the EcoCAR drive schedule and averaged less than 2 Lge/100km in fuel consumption.
Taking home second place at the Year Two Finals, Virginia Tech won a combined eight trophies including Best Electrical Presentation and Best Braking, and was the runner up in Best Petroleum Energy Usage and Best Tailpipe Emissions. The team’s E85 engine with a 15 kilowatt belted alternator and 80 kilowatt rear traction drive successfully completed every dynamic event. Virginia Tech’s vehicle stopped within mere seconds during the Braking event and won Best Static Consumer Acceptability with a clean engine compartment, five passenger seating, and a fully functional touch screen.
Penn State University placed third overall with a 1.3L, B20 biodiesel series hybrid. At the Year Two Finals, the team took home eight awards, including Best AVL Drive Quality, Best Social Media, 2nd in A123 Battery Design, 3rd in Outreach, and was the runner up in Best Fuel Consumption and Best Tailpipe Emissions. The team’s fuel consumption averaged around 4.1 Lge/100 km and the EcoCAR displayed impressive acceleration linearity and quick throttle response during the Drive Quality dynamic tests. In addition, the team was able to host more than 50 outreach events and increase media relations by more than 400 percent in the outreach program.
Although Mississippi State, Virginia Tech and Penn State were the top three teams in Year Two, there was a variety of other awards given out during Finals. You can find the complete list of winners, here.
With only one year left, the EcoCAR competition will get fierce as all 16 EcoCAR teams fight for the number one spot in Year Three. Who will it be? Check back to the Inside the Green Garage blog throughout Year Three for team and competition updates!
