Red Bull team boss Christian Horner has revealed they now have a power unit agreement in place for the 2016 season.
Horner said: "We have an agreement with an engine [supplier] for next year which hopefully will be confirmed in the coming days," according to autosport.com
"It will have a development path, which ironically, in a way, is what we were trying to achieve 12 months ago, and we'll see how that goes."

Horner may not have named the manufacturer the deal is with, but everyone is aware they will once again be using Renault power units.
This comes after a very public fall-out throughout the season after Red Bull made it clear on several occasions they were not happy with their current power unit's reliability or performance.
This led Red Bull to inform Renault they would be leaving their contract one year ahead of schedule and would look elsewhere for their power units.
They contacted both Ferrari and Mercedes only for the latter to flat-out refuse supplying their rivals whilst the Italians would only supply them with power units built to the same specification as the 2015 Ferrari engine instead of the new, improved model they will use for the coming season.
Both of these options were unacceptable for Horner's team, who were hoping they would be more competitive for the coming season and left them in a precarious position.
Many believed the damage had been done with Renault and there was no way their relationship could be saved. It looked certain the team would instead drop out of Formula One all together.
Of course, Bernie Ecclestone was not going to allow that to happen, therefore, during the Russian Grand Prix race weekend he stepped in and held meetings with various team principles and Renault management to make sure Red Bull did not leave.
It is not known what was said or did to turn the situation around but once again the F1 supremo has got what he wants.
It remains to be seen how good this Renault power unit will be next year and if Red Bull will regret their decision to stay with their current supplier.
