Red Bull Powertrains will be working in conjunction with Ford to help deliver the engine that will power the current world champion squad for F1’s new rules era.
It already has its dynos hard at work in evaluating the performance of its new turbo-hybrid design and while there have been various rumours about the level of progress Red Bull is making with its project, Horner insists everything is on track.
Speaking to Autosport about where things were at, Horner said: “With the engine, we're on an aggressive curve being a brand new power unit manufacturer but the team is really rising to that challenge.
“Our facilities are complete, both from a test and development point of view with dynos and rig rooms, etc, and manufacturing capability.
“But two years in the engine world is a very small period of time. We're on a steep learning curve, but we're on that curve and where we would expect to be on that curve at this point in time.”
