Matthew Carter maintains talks between Lotus and Renault are progressing well following the confirmation that Jolyon Palmer will partner Pastor Maldonado next season.
Talks between the two parties have been ongoing for several months, with no clear indication over whether the French manufacturer will follow through with a buy-out despite signing a 'letter of intent' last month in an effort to stave off Lotus' court order over tax debts.
It comes as Lotus announced it will be promoting its reserve driver Palmer into a race seat for 2016, joining the already confirmed Pastor Maldonado and replacing Haas-bound Romain Grosjean.
However, though Carter refused to be drawn on the specifics of the talks taking place, he nonetheless gave a positive outlook.
“It's difficult for us to talk in any great detail but we certainly have an idea of the route we are going to go down next year. We can't confirm anything at this stage but we certainly are heading down that route and things back at Enstone are taking shape.”
