Adrian Newey insists he is committed to winning more Formula 1 world championships with Red Bull after the team racked up its fourth consecutive title double.
Newey has previously voiced a desire not to spend his entire career in F1 and has also been a regular target of approaches from other teams. But he insists that the enjoyment he gets from working at Red Bull means he remains fully focused on his role as chief technical officer for the team.
"The joy of working with this team is to have been involved in taking it from the ashes of Jaguar to where we are today," he said. "Having achieved some success over the last few years, the enjoyment is really in working with my colleagues in Milton Keynes, continuing to develop the way we operate with Christian [Horner]. It has been a great ride.
"Next year is a huge challenge with the regulations so at the moment I'm fully focused on that."
Newey stressed that the scale of the challenge the team faces in 2014 cannot be underestimated. As well as the change in powertrain, there are also significant changes to the cars.
"Next year's regulation changes are very big," said Newey. "The aerodynamic changes are not quite as big as we had for 2009 but they are still very significant.
"The engine regulation changes are massive and it's not at all clear whether one engine manufacturer will steal a significant advantage over the other two. Reliability will be a big issue, certainly at the start of the season if not for the whole season.
"The installation of the engine in the chassis is very complicated, so there are a lot of variables."
