Despite the fact that the former Formula 1 driver was not among the top ten in the overall table, Ericsson gets a new contract with Chip Ganassi Racing.
"Marcus proved that he belongs here, and this season he contributed to the team's success.
He drove selflessly, and helped Scott Dixon win the championship ", writes the stable's CEO Mike Hull in a statement.
Last season ended with a twelfth place in the driver's championship for the Swede, who finished one place behind his compatriot and teammate Felix Rosenqvist.
The team's third driver, Australian Scott Dixon, won the overall series.
"I want to thank Chip (Ganassi, the owner) and the entire CGR organization for their faith in me", says Ericsson to the stable's website.
"Neither wants nor can enter"
According to the stable, Ericsson's contract extends over several years.
More details will be revealed closer to the start of the season.
- I neither want nor can go into exact details.
The team does not want to discuss it, but it feels great to gain the trust of Chip Ganassi Racing, Ericsson tells Aftonbladet.
The stable's other Swede, Felix Rosenqvist, has been rumored to be on his way away from Chip Ganassi Racing.
Information places him in McLaren, but no confirmation has come from either Rosenqvist or the stable.
