The goal: 80 days, 18,000 miles, no emissions. Yesterday, the Zero Race electric car world tour began in front of the United Nations Palace in Geneva, Switzerland. Four teams--from Australia, Switzerland, Germany, and South Korea--won't actually race one another to cross a finish line. Instead, spectators and experts will determine the winner based on reliability, energy efficiency, safety, design, and practicality, as the tour is meant to show the feasibility of electric vehicles.
