American Robby Gordon, who faces Dakar Rally disqualification after his Hummer was deemed to have broken race regulations, won the 12th stage then blasted rivals for questioning his integrity.
Gordon, who has appealed the stewards' decision imposed during the week, came home ahead of Russia's Leonid Novotskiy, in a Mini, and Ginel De Viliers of South Africa, driving a Toyota.
France's Stephane Peterhansel, who was sixth today after his Mini got bogged down in a sand dune, remained on top of the overall standings.
Peterhansel, a six-time motorcycle champion and three-time car winner, is 1 hour and 44 minutes ahead of Gordon who is fourth overall.
