From ERC24.com:

'European fan favourite Petter Solberg, who is both a previous WRC title holder [2003] as well as the current World Rallycross Champion looks to build on his hugely successful second year, entering 2015 in his third season since his return to the sport in 2013. Liam Doran widely recognised as Britain’s hottest Rallycross prospect and two-time X Games gold medallist completes the formidable team. The joining of forces was admittedly made easier due to the fact that the drivers both run with Citroën DS3 SuperCars, as Per-Espen Løchen of the SDRX team suggested, stating in said press conference that both drivers have individual sponsorship agreements. Therefore, to run a two car team cost no extra money, needs just a new logo, and makes sense in the quest for the team championship title.'
