by X-raid slowed down Peterhansel. Peugeot returned for the 2015 event with an all-new, diesel-powered, two-wheel drive contender, but failed to make an impact as X-raid's Minis once more dominated. Al-Attiyah won the event in his second year for the team, while Coma racked up a fifth title in the bikes after the defection of long-time rival Despres to the car class and Peugeot. Peugeot did however see success in 2016 with Peterhansel behind the wheel, racking up his 6th win in the car category, and again in 2017 and 2018 until Peugeot decide to officially leave the competition. In 2019 Toyota won for the first time with Nasser Al-Attiyah (in his third victory with three different manufacturers). The bike category saw the KTM works team rider, Australian Toby Price, take his first Dakar victory, winning his second title in 2019. Sam Sunderland and Matthias Walkner won the 2017 and 2018 edition also for the team from Mattighofen (18 overall victories as in 2019). Saudi Arabia The rally has been held in Saudi Arabia since 2020. Since 2022, the rally has been the season-opening round of the World Rally-Raid Championship jointly sanctioned by the Fédération Internationale de l'Automobile and Fédération Internationale de Motocyclisme.

Motorbikes For the 2005 rally regulations introduced a limit of 450cc for twin cylinder motorbikes. Single cylinder motorbikes were still open class with no capacity limit. As of 2011, the engine displacement limit for all motorbikes competing in the Dakar Rally is 450cc. Engines may be either single or twin cylinder. Riders are divided into two groups, "Elite" (Group 1) and Non-Elite (Group 2), with the latter subdivided into two further groups - the "Super Production" (Group 2.1) and "Marathon" (Group 2.2) classes. "Marathon" competitors are not permitted to change such key components as the engine (including the engine case, cylinders and cylinder heads), the frame, the forks or swinging arm, whereas those in the "Super Production" and "Elite" classes may
