X-Prize: Performance tests knock out more competitors

As the Automotive X Prize field narrows, the competition draws closer to finding a 100-mpg car that will be acceptable to consumers.

Today, 11 remaining competitors took to the track in Consumer Reports accident avoidance tests. The teams had to be able to achieve 45 mph in our emergency avoidance test, accelerate in 60 mph in less than 18 seconds (or 15 seconds for the two remaining Edison2 cars in the Mainstream category), and stop from 60 mph in less than 170 feet. Essentially, every current production car can pass these targets.
