Next year's Dakar Rally will start from Lisbon and is subject to new speed limits and safety measures.
The rally runs from 31 December to 15 January 2006, with 508 teams competing on a route through Spain, Morocco, Mali, Mauritania, Guinea and Senegal.
A limit of 150kmph (93.2mph) has been imposed on bikes and trucks to make the event fairer and safer.
The use of global positioning systems is also being reduced to make drivers and navigators rely on road books.
Two motorcyclists - two time winner Fabrizio Meoni and Jose Manuel Perez - died in this year's race.
Former world rally champion Carlos Sainz will be making his debut in the event, driving a Volkswagen Touareg.
