In 2014, Kubica started in the first round of the ERC season. He won the Internationale Jänner Rallye to claim his first victory in that championship, after coming very close on a number of occasions in 2014. His strong results in the stages for this rally eventually netted him the "Ice Master" trophy for the best driver in snow events that season. For the rest of the season, he participated in the main WRC class for the RK M-Sport, running as separate team, backed by Polish oil company Lotos. Kubica began his WRC campaign by taking the lead of the Monte Carlo Rally through the first two stages, but later retired on the second day after crashing out on SS9.

His best result was a 6th place at the Rally Argentina, a place lower than his highest finish in 2013 (5th in Germany) in a WRC-2 car. He finished the season in 16th place with 14 points. He finished the year on a positive note by winning the non-championship Monza Rally Show, beating motorcycle legend Valentino Rossi to second.
