X Prize Spotlights Super Fuel-Efficient Cars


Recently the X Prize Foundation and Progressive Automotive Insurance handed out $10 million in prize money to three teams that demonstrated the most super fuel-efficient vehicles that exceed 100 MPGe (Miles per Gallon or Energy Equivalent) -- a new way to compare the efficiency of gasoline to electric and other alternative fuel vehicles.

Here are descriptions of the winners from the official press release:

$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.

Here are some photos I took of the event on the grounds of the Historical Society of Washington, D.C.



And here are videos I took of the vehicles on display at the awards ceremony.
