Find below a comment from Red Bull Motorsports Consultant Dr Helmut Marko.
Dr Helmut Marko: "Over the last 10 years, many successful, we have been through every emotion with our current engine supplier. As usual at the end of another long season, emotions are running high but it is a valued relationship and will remain so.
There has never been any question that we have not been treated fairly and equitably by our engine supplier. And that is still true today."
