Nick Heidfeld has settled in well at Renault ahead of the 2011 season.
That is the news of boss Eric Boullier, who has also given a promising update on the progress of the team's injured regular Robert Kubica.
"Nick has a very good approach," the Frenchman is quoted by Swiss website 20min.ch.
"He gets deeply involved and has already convinced the technical team of his value," explained Boullier. "He has quickly built around himself a climate of confidence."
Heidfeld recently said he does not feel treated like a "stop-gap" by Renault.

On Kubica, Boullier said the Pole is "ahead of all expectations" in an Italian hospital.
"He is extremely motivated and upbeat, and even if it's not rosy every day, overall he is doing exceptionally," added Boullier, who said he keeps in contact with Kubica by text message.
Boullier reiterated that he does not regret allowing Kubica to go rallying in between his F1 duties, but admitted he would perhaps rethink the "category" of vehicle used by the driver.
