Automotive X Prize: Knockout phase delivers the punches

"The Automotive X Prize entered the second-week of its Knockout phase Monday, with the remaining teams proceeding through emissions and dynamic testing. Consumer Reports is again conducting most of the track tests, such as acceleration, braking, and emergency-avoidance maneuver evaluations from the previous phase, plus adding lateral g and passing tests. We are again seeing the competition up close, and it is getting tougher to watch as teams falter."
