The second driverless car competition of the DARPA Grand Challenge was a off-road course that began at 6:40 am on October 8, 2005, near the California/Nevada state line. All but one of the 23 finalists in the 2005 race surpassed the distance completed by the best vehicle in the 2004 race. Five vehicles successfully completed the course: Vehicles in the 2005 race passed through three narrow tunnels and navigated more than 100 sharp left and right turns. The race concluded through Beer Bottle Pass, a winding mountain pass with sheer drop-offs on both sides. Although the 2004 course had required more elevation gain, and some very sharp switchbacks (Daggett Ridge) had been required near the beginning of the route, it had had far fewer curves and roads than the 2005 course. The natural rivalry between the teams from Stanford and Carnegie Mellon (Sebastian Thrun, head of the Stanford team was previously a faculty member at Carnegie Mellon and colleague of Red Whittaker, head of the CMU team) was played out during the race. Mechanical problems plagued H1ghlander before it was passed by Stanley. Gray Team's entry was a miracle in itself, as the team from the suburbs of New Orleans was caught in Hurricane Katrina several months before the race. The fifth finisher, Terramax, a 30,000-pound entry from Oshkosh Truck, finished on the second day. The huge truck spent the night idling on the course and was particularly nimble in carefully picking its way down the narrow roads of Beer Bottle Pass. National Qualification Event (NQE) Of the original 195 applicants, initially 40 teams were selected to participate in the National Qualification Event (NQE). Three teams were added on Aug. 23, 2005 to the semi-finalist 40 teams who were selected from site visits, sending 43 teams to the NQE. The National Qualification Event was held at California Speedway in Fontana from September 27 through October 5. The results of the NQE were used to cut the 43 teams down to 23 for the race on October 8. Vehicle performances at the NQE were judged by (1) elapsed time to complete the course; (2) number of obstacles successfully passed without contact; (3) number of gates successfully passed. DARPA did not reveal the relative importance of these three factors. DARPA's final ranking of the vehicles, for purposes of pole position in the Grand Challenge Event (GCE), may have been partly subjective. The
