398-cubic-inches, with higher 10.5:1 compression bringing output to and of torque, and certain safety improvements included. The car was reunited with Blu Plemons, the co-driver of the original (the driver, Keith Anderson, was killed in practice for the 1957 Indy 500) at the starting line. Among the nine other entries in the "Original Pan-Am" class were four Lincolns, including a 1949 model that contested the original Pan-Am. 2006 also saw the debut of a 'modern' category, with the sole entry of a Lotus Elise ('Chica Loca') run by Rachel Larratt. This class, called Unlimited, allows machines manufactured after 1990 to compete in the race. Controversially, in recognition of the high value of some of the supercars thus allowed to run, organisers of the race foresee the need to allow case-by-case exceptions from the race's normal safety equipment rules. The class is intended to raise the race's profile beyond a market elderly enough to recall the original four races, to ensure the survival of the event. Also, it is a reflection of the increasing scarcity of eligible vehicles, and of the effect of modern rallies like the Gumball 3000. 2007 The 2007 event, according to Eduardo de León Camargo (President emeritus of La Carrera Panamericana), was the largest recreation to date. More than 100 teams participated in seven days of racing from October 26 to November 1 inclusive, with an additional pre-qualifying stage held outside Oaxaca on Thursday October 25. Cars competed in the usual ten classes along a course starting in Oaxaca. From there, the route led the convoy in day-long sections consecutively between Tehuacán, Puebla, Querétaro, Morelia, Aguascalientes, Zacatecas and Nuevo Laredo. As the 20th anniversary of the race's recreation, 2007 saw Mr. de León gave thanks to the committee which has for 19 years organised the race, and the presence of President of the Mexican Motorsports Federation, José Sánchez Jassen, and President of the Mexican Rally Commission, Rafael Machado. During the conference announcing the route, special mention was reserved for the efforts of Mexican law enforcement in general and of the Highway Patrol in particular, under the command of Comandante Julio Cesar Tovar, and to thank Mexican Federal, State and Municipal authorities for collaborating to ensure smooth running of a challenging project.
