Red Bull's Christian Horner said he was encouraged by some of the recent developments at Renault and has not ruled out the possibility of continuing to work with the manufacturer post 2016.
The relationship between Red Bull and Renault suffered when the latter's power unit did not meet expectations in 2014 and 2015. However, Horner feels to inclusion of people like Bob Bell to the staff signals Renault's intent to improve and be more reliable going forward. The willingness of both parties to try and map the way forward has also contributed to improved relations.
"We've had some constructive discussions with Renault over the months and they seem to be acting on some of them," Horner told F1i this week.
"They've embraced Mario Illien, made changes to their technical infrastructure and got quality personnel involved now like Bob Bell.
"I think change will start to be addressed there. That is going to take time. We are going to keep an open mind, certainly through the first half of the year."
