The Progressive Automotive X PRIZE, an international competition launched in 2008 with a $10 million prize purse designed to inspire a new generation of viable, super fuel-efficient vehicles, recently announced its winners (video at the end of this post). They are:
$5 Million Mainstream Class Winner:
Edison2 “Very Light Car #98” (Charlottesville, VA)
Economy: 102.5 MPGe
Fuel: E85 ethanol
Boasting the lowest drag coefficient of any car with four wheels tested in the GM wind tunnel and at the Chrysler Proving Grounds, this vehicle demonstrated over 100 MPGe on the test track, and verified in the lab, under stringent testing conditions using a highly innovative small displacement engine. Its low weight of just 830 pounds is a tribute to its use of light weight materials, reduced engine displacement and a host of other weight-saving innovations.
$2.5 Million Alternative Side-by-Side Class Winner:
Li-ion Motors Corp “Wave II” (Mooresville, NC)
Economy: 187 MPGe
Fuel: Battery Electric
This side-by-side two-seat battery electric car was built on a lightweight aluminum chassis and weighs in at only 2,176 pounds, despite the weight of its powerful lithium ion batteries. The Wave II demonstrated outstanding low mechanical and aerodynamic drag that resulted in 187 MPGe in combined on-track and laboratory efficiency testing, a 14.7s zero-to-60 mph acceleration time, and over 100 miles range over a real-world driving cycle.
$2.5 Million Alternative Tandem Class Winner:
X-Tracer Team Switzerland “E-Tracer #79” (Winterthur, Switzerland)
Economy: 205.3 MPGe
Fuel: Battery Electric
This tandem two-seat vehicle combines the best of motorcycles and automobiles. This clever design has two extra outrigger wheels that deploy at low speed to stabilize the vehicle. At 1436 pounds, the E-Tracer is able to deliver over 100 miles in range, led the competition with over 200 MPGe in combined on-track and laboratory fuel efficiency and achieved a zero-to- 60 mph acceleration time of just 6.6 seconds.
“We’ve seen a shift in the market since we first launched this competition, and a greater awareness by people everywhere to think more seriously about the actions we take, and how they affect our environment,” noted Peter Diamandis, Chairman and CEO of the X PRIZE Foundation. “Gas mileage ranks as one of our top concerns when purchasing a new vehicle and I believe strongly that the innovations showcased throughout the life of this competition will continue to impact and improve our car buying options for the future.”
“Congratulations to the winners and to all the teams who competed over the course of this competition. Their innovations and hard work are truly inspirational,” said Glenn Renwick. “We’re extremely proud to support a competition that will result in more super fuel-efficient vehicle choices; choices that will make people’s lives better.”
There will now be opportunities for winners and other competitors to move forward with their inventions. Under a U.S. Department of Energy-funded technical assistance program, qualified Progressive Insurance Automotive X PRIZE competitors will obtain funding support for access to key automotive expertise and test facilities to assist them in readying their vehicles and technologies for market introduction.
