The race to design and build a production-capable vehicles that exceed 100 Miles per gallon (or energy equivalent MPGe) is in full gear this summer as scores of ultra efficient vehicles compete in the Progressive Automotive X-Prize competition. After months of trials, races and multi-stage testing the knockout stage just ended, leaving 15 of the original 26 cars still standing. The 15 vehicles in three different classes will continue on to compete in further trials to determine which vehicle really has what it takes to be the most efficient vehicle around. Read on for a roundup of the incredible fuel-efficient cars moving on to the final stages!
During the knockout stage, competing vehicles had to pass a series of technical inspections and on-track safety tests. Vehicles not only had to complete emissions, efficiency, and range events, but they also had to achieve fuel economy (67 MPGe) and range requirements (134 miles for Mainstream class entries and 67 miles for the Alternative class). Cars in the Mainstream class must seat at least four passengers, have four wheels, and have a minimum 200 mile range, while cars in the Alternative class must seat at least two passengers with a minimum 100 mile range and no minimum on the number of wheels.
Cars to watch out for in the next few months of competition include Finland’s RaceAbout, the X-Tracer, and Team Li-ion Motors. Follow the X-Prize updates through their facebook page, or check out the website for standings and data on each car. Progress Insurance, who sponsors the Automotive X-Prize will be doling out $10 million in prize money to the winners in each class come September.
