He won't be around at Mercedes in 2014, but Ross Brawn says he is "pretty comfortable" with the team's approach for the new campaign.
Brawn has decided to step down as team principal of the Brackley-based squad and will take a six-month sabbatical before deciding on his future.
It means he will miss out on what could be an interesting start to the season as it will mark the introduction of new regulations with the change from the 2.4-litre V8 engines to 1.6-liter V6 turbos and the use of energy recovery systems the biggest.
Brawn welcomed the "extreme" changes and is optimistic that Mercedes are well prepared, and it is no surprise that Paddy Power have made them second favourite behind Red Bull to win the Constructors' Championship.
"I think it's going to be a pretty extreme case next year," he told Autosport. "I've been involved in those situations more than once, 1994 was a good example, 2009 was a good example and I'm sure there are ones in between that don't come to mind!"
He added: "These regulation changes of the magnitude that we have got for '14, they are great opportunities and I hope we are grabbing this opportunity.
"We have certainly put enough resource and effort into it. I'm pretty comfortable with the way that we have approached it."
Mercedes did well to finish second in the Constructors' Championship this year, but there is always the danger that you can stretch your resources too much by focusing on one season.
Brawn, though, says they didn't compromise their 2014 challenger and you can bet on their title hopes and more at Paddy Power.
"I am pretty happy. I think it has been a good balance," he said.
"I'm not looking back being worried that we did not put enough resource into 2014. Seeing where the car is now, it is pretty much on schedule. It's achieving most of the targets we wanted to achieve.
"We have been working on it for quite a long time. That's one of the advantages of having Geoff [Willis] and Aldo [Costa] on the team.
"Geoff started the '14 project, then Aldo picked it up in the middle of this year. Bob [Bell] focused a bit more on the current car to keep that progressing along.
"So I don't think we've had to make any heavy compromises in terms of keeping the programmes running well together."
