The Honda Racing team have confirmed former Ferrari technical director Ross Brawn as their new team principal.
As revealed in April by autosport.com, Honda had contacted Brawn in a bid to convince the Briton to lead the Japanese squad from next year.
Brawn is on sabbatical after 10 years as technical director of Ferrari.
Honda said Brawn will have full responsibility for designing, manufacturing, and engineering the team's car.
Brawn will work alongside Nick Fry, who continues as Chief Executive of the team.
"I am very excited to be joining the Honda Racing F1 Team," said Brawn. "Honda has a proud heritage in Formula One and the opportunity to help the team to realise its potential represents a fantastic new challenge for me in the sport.
"The team has already done a great job of giving due consideration to its future and has spent a good deal of time putting in place both people and first class engineering resources to achieve its ambitions. I look forward to working alongside what I know to be some very talented people and helping Honda to rediscover its winning ways."
Fry added: "One of my main tasks over the past six months has been to attract new talent to the Honda Racing F1 Team and we have made a number of key appointments in the areas of aerodynamics, design, engineering, marketing and on the racing team.
"Today's announcement that Ross Brawn is to join our team is a very satisfying conclusion to the process of refreshing and revitalising a strong and determined team. Ross obviously needs no introduction.
"His experience of winning world championships in Formula One will be crucial as we seek to put Honda back into championship contention and I am delighted that we will be working together to achieve that."
Brawn will start work with Honda on 26 November.
