Motorcycle rider Sam Sunderland became the first Briton to win the Dakar Rally in any category while French veteran Stephane Peterhansel won the car crown for his 13th career title.
Dubai-based Sunderland, on a KTM, beat Austrian teammate Matthias Walkner by 32 minutes after the final 64km competitive stage in Rio Cuarto, Argentina.
He then rode 700km to the official finish in Buenos Aires, where he stood on top of the podium.
"Unbelievable. When I crossed the line I felt all the emotion hit me. The weight on my shoulders of the race over the last week, leading the rally has been really heavy," said Sunderland.
Last year's motorcycle winner, Toby Price of Australia, retired with a broken leg on the fourth stage.

Defending champion Peterhansel, who has won the Dakar six times on bikes and now seven times in cars, beat Peugeot teammate and compatriot Sebastien Loeb by five minutes.
Cyril Despres completed a one-two-three for the manufacturer.
The Dakar Rally began in 1978 as a race from Paris across the Sahara to the Senegalese capital but switched to South America in 2009 for security reasons.
This year's race started in Paraguay and also went through Bolivia.
