The Dakar legend utterly dominated the majority of the 2013 event, establishing his X-raid Mini up front even before the potentially faster Red Bull Buggies of Nasser Al-Attiyah and Carlos Sainz dropped out.
Peterhansel's eventual margin of triumph was 42 minutes over Giniel de Villiers' Toyota.
X-raid filled four of the top five places. Nani Roma fought back from early delays to third before dropping behind Mini stablemate Leonid Novitskiy again when he waited to run as support to Peterhansel on the penultimate day.
Orlando Terranova brought one of X-raid's older BMWs home fifth, finishing a close second to the charging Roma on Saturday's concluding stage.
Various problems for Guerlain Chichert's rapid SMG Buggy meant that he only finished eighth behind Carlos Sousa's Great Wall and fellow SMG man Ronan Chabot.
That was still better off than Robby Gordon. The American's Hummer flew in the final stages as he recovered from the early disasters that had left him six hours behind in 43rd place just four days in.
