Robert Kubica has pulled out of Rally Argentina to focus on restructuring his World Rally Championship team.
The former grand prix driver, whose RK World Rally Team was created just before the start of the season, announced the decision not to compete in the fourth round of the championship just three days before the start of the event.
Kubica said the decision had not been easy, but he feels it is the best one for the future of the team.
"Unfortunately we will not start in Argentina," said Kubica. "This has been a very difficult decision to take.
"We have always planned to compete in Rally Argentina and although part of the team, including the car, is already on site, it was necessary to skip this event.
"It is a real challenge to compete in the World Rally Championship and although I won six stages in the first three rounds, we have to be realistic and focus on improving the team in many areas.
"We plan to come back for the Rally de Portugal with a different structure, which will be systematically fine-tuned."
The Pole is yet to finish in the points this year, having retired in Monte Carlo and finishing 19th in Sweden and 18th in Mexico.
