An out of court settlement between the team and axed driver Nick Heidfeld has cleared the way for Renault to sign Bruno Senna for the rest of 2011.

A media statement said German Heidfeld, who had hoped to return to the R31 in Singapore after a London High Court hearing, has reached "an amicable settlement" with Renault.

The 34-year-old and the team have therefore "chosen to part company with immediate effect", with Renault boss Eric Boullier describing it a "swift and reasonable solution".

"Our separation process was already a painful one, and neither of us wanted to go through another legal hearing," added the Frenchman.

Renault promptly confirmed Brazilian Senna as Vitaly Petrov's new regular teammate for the remainder of 2011, with new GP2 champion Romain Grosjean as the reserve.
