Nico Rosberg retired from Formula One immediately after claiming the 2016 Drivers' Championship with Mercedes, subsequently transitioning into entrepreneurship and investment in technology and sustainability ventures. When Extreme E was announced — an electric SUV off-road series racing in environmentally sensitive locations worldwide to raise climate change awareness — Rosberg entered with his own team alongside other high-profile championship-winning drivers including Lewis Hamilton (X44) and Jenson Button (JBXE). The series required each team to field one male and one female driver who would share equal driving duties, splitting each race between them with a mandatory mid-race driver swap.
Rosberg X Racing entered the inaugural 2021 Extreme E season with Australian rally and cross-country driver Molly Taylor alongside Swedish rallycross champion Johan Kristoffersson. The pairing proved formidable across the five-round season, which opened with the Desert X-Prix in Saudi Arabia in April 2021 and concluded in December in the United Kingdom. RXR emerged as the first-ever Extreme E champions, with Taylor and Kristoffersson claiming the title ahead of the competitive field.
The team did not retain the title in 2022, with that season's championship going to Lewis Hamilton's X44 team with drivers Cristina Gutiérrez and Sébastien Loeb. RXR regrouped and returned to winning form in the 2023 season, the third campaign of the series, again with Kristoffersson paired this time with Swedish driver Mikaela Åhlin-Kottulinsky. The combination won the 2023 championship, giving Rosberg X Racing a second Extreme E title and making Kristoffersson a two-time Extreme E champion.
The 2024 season proved turbulent for the entire Extreme E championship. After the fourth season started in Saudi Arabia in February 2024, Extreme E cancelled the remaining rounds in September before the scheduled Island X-Prix in Sardinia and Phoenix could take place. Veloce Racing's Kevin Hansen and Molly Taylor — Taylor having moved from RXR — were leading the standings at the point of cancellation. Rosberg X Racing did not participate in the final standalone Extreme E event held in October 2025 in Qiddiya City, Saudi Arabia, ahead of the series' transition to the hydrogen-powered Extreme H championship.
The core of the team's competitive success was Johan Kristoffersson, one of the most decorated rallycross drivers in the sport's history, who drove for RXR in multiple seasons. Molly Taylor, the 2016 Australian Rally Champion, was instrumental in the inaugural title run. The team embodied Extreme E's mandate of gender equality in motorsport through its driver pairings, and Nico Rosberg used the platform publicly to advocate for sustainable motorsport and electric vehicle technology in alignment with his post-F1 entrepreneurial focus.
Rosberg X Racing's back-to-back championship wins in 2021 and 2023 made it the most successful team in Extreme E history by title count. The team demonstrated that a well-capitalized and strategically assembled entry could compete at the front of a new electric off-road series from its very first season. Nico Rosberg's involvement brought significant media attention to Extreme E and its environmental mission during the series' formative years. When Extreme E concluded ahead of the Extreme H transition in late 2025, RXR stood as a defining team of the championship's short but notable existence.
