Since the beginning, more than 93 universities across North America and 16,500 students have participated in AVTCs. Each year, 200-500 students join forces in AVTCs mission of educating the next generation of automotive engineers and advancing state-of-the-art fuels and vehicle technologies.
During EcoCAR: The NeXt Challenge, 16 universities from North America competed over the three-year span of the competition. These universities included:
Embry-Riddle Aeronautical University
- Location: Daytona, Florida
- Vehicle Design: The EcoEagles’ vehicle was a plug-in hybrid electric vehicle (PHEV), which consisted of a GM 1.3 L diesel engine running on B20 biodiesel, a GM two-mode transmission, and an A123 Systems 330 V, 12.9 kWh lithium-ion battery pack. The vehicle was able to drive approximately 20 miles on electric-only power. Once the battery was depleted, the vehicle switched to hybrid mode with the engine turning on to sustain the battery and power the vehicle.

A 1.3 L, four-cylinder GM turbodiesel engine rated at 71 kW (95 hp), which used B20 biodiesel and was assisted by 37 kW (50 hp) TM4 electric motor, were connected to a GM four-speed transmission. A second 37 kW TM4 motor was attached to the rear axle for enhanced vehicle acceleration and regenerative braking. In addition, a custom 11.3 kWh EnerDel lithium-ion battery powered the TM4 motors and offered electrical storage for the regenerative braking. Finally, the Rose-Hulman EcoCAR vehicle had the capability to run in three different powertrain modes: electric only, diesel only, and hybrid.

Texas Tech University
- Location: Lubbock, Texas
- Vehicle Design: The Texas Tech parallel hybrid utilized a 1.6 L GM Europe four-cylinder engine running on E85 ethanol mated to the GM front-wheel drive, two-mode transaxle. The two-mode vehicle had four traditional fixed gears and two 55 kW electric motors. The motors were powered by a 330 V, 12.7 kWh A123 Systems battery pack. The battery pack allowed the vehicle to use only electric power at low speed and the second electric motor allowed the vehicle to be more efficient at highway speed with the engine on. The vehicle also sported Texas Edition badges adding flair to match the Texas flag on the roof.

- Vehicle Design: HEVT designed, built, and refined a split parallel extended-range electric vehicle (EREV). The vehicle could plug into a standard wall outlet to charge a high energy capacity A123 Systems battery, and run in electric-only mode for more than 65 km (40 miles). Tractive power in electric-only mode provided by a rear axle-mounted 125 kW UQM permanent magnet electric motor with regenerative braking capability. Once the battery was depleted, a 2.4 L GM FlexFuel engine provided additional driving range by burning E85 ethanol and driving a multi-speed automatic transmission on the front axle. A second 8 kW MES-DEA electric motor was used as a belted alternator starter to allow for engine idle-stop, electric energy generation, and engine loading.

West Virginia University
- Location: Morgantown, West Virginia
- Vehicle Design: The heart of WVU’s vehicle was the GM two-mode electrically variable transmission (EVT), which provided two continuously variable EVT modes and four fixed gear ratios, enabling flexibility to optimize performance efficiency and emissions for a wide range of driving conditions. A fuel efficient 1.3 L, four-cylinder SDE turbodiesel engine rated at 71 kW (95 hp) and 200 N-m (147 ft-lb) peak torque fueled with B20 biodiesel fuel provided primary propulsion power. Electrical energy storage was accomplished with a lithium-ion battery pack composed of four 25S2P battery modules from A123 Systems. Simulation results indicated that the vehicle could achieve 6.2 L/100 km (35 mpg) gasoline equivalent, with well-to-wheels (WTW) greenhouse gas (GHG) emissions of approximately 150 g/km and WTW PEU of 0.40 kWh/km.
