It doesn’t take a major automaker, or even an established company to build a credible competitor for the Automotive X Prize. It turns out, it doesn’t even need a team run by grownups.

The West Philly Hybrid X team consists of a group of inner-city high school kids who do their work as an after-hours club. This volunteer effort has many benefits to the participants, including teaching teamwork and engineering essentials. Life skills and inspiration alone would make being involved in the program worthwhile, but the high schoolers and mentors can take pride in having both entries accepted as finalists in the competition. One is an Alternative Class car that uses a diesel hybrid drivetrain installed in a widely available sports-car kit. Their Mainstream Class entry (which requires four seats, four wheels, and a 200 mile range), made a visit to New York City as part of an event to announce the 43 finalists. (Read “Automotive X Prize finalists announced.”)

Called the West Philly Hybrid X EVX Focus, the Mainstream entry is a Ford Focus converted to hybrid-electric power, using a 60-horsepower electric motor coupled to a 1,300 cc, 80-hp Harley-Davidson motorcycle engine. The electric motor is powered by a 10.2 kWh lithium-iron phosphate battery pack. The team says the Focus will maintain all its five-passenger cargo capacity and have a 13.8 cubic-foot trunk. Mileage is estimated to be 110 to 120 mpg equivalent, using gasoline and electricity. 

The team focused on using all-American technology, well, make that North American: The Focus is made in Mexico, and the Harley-Davidson engine in Wisconsin. The team has also explored having the car built locally in Philadelphia.

X Prize teams have to have a viable business plan to produce and sell 10,000 of each of their cars. The West Philly Hybrid X team plan factors buying Focus chassis as “gliders”--sans engine and transmission-- from Ford, to keep the total price under $20,000.

Regardless of the final results from the Auto X Prize to be determined next year, clearly the West Philly team is made up of winners.
