McLaren team principal Martin Whitmarsh said it was crucial for the team to agree a new engine deal with a car manufacturer.
The team announced last week it will reunite with former engine supplier Honda in 2015.
“McLaren needs to be supported and teamed in a full works effort with a major automotive manufacturer,” said Whitmarsh at a Vodafone McLaren Mercedes phone-in.
“We’re going to be doing all we can to win races with Mercedes this year and next, but inevitably moving to Honda in 2015 gives us a bedrock of being one of the big teams.
“It ensures that in the long term we have the resources, the correct structure and focus, to be successful.”
Whitmarsh added the switch between engine suppliers, which will come after the first year of F1’s new engine regulations, will be “a tough challenge for the team”.
McLaren and Honda won their first race together in the 1988 Brazilian Grand Prix and their last race together in the 1992 Australian Grand Prix. During that period they amassed 44 wins out of a possible 80, four consecutive constructors’ championship victories and four drivers’ titles won by Ayrton Senna (three) and Alain Prost (one).
Driver Jenson Button will be reunited with Honda having used their engines between 2003 and 2008.
Red Bull Air Race: Yoshi Muroya joins Sato as Japanese champs at Indy
Takuma Sato isn’t the only major Japanese athlete to take home top honors at the Indianapolis Motor Speedway this year. Countryman Yoshihide Muroya joined him in that on Sunday after winning Red Bull Air Race at IMS, and the Red Bull Air Race World Championship in the process.
Fittingly, the 101st Indianapolis 500 champion was there on site to join him in the celebration.
Muroya flew with a track-record run in the final and erased the four-point deficit to points leader Martin Sonka. The record run came after a disappointing qualifying effort of 11th in the 14-pilot field in the Master Class.
A day after the win, Muroya joined Sato in heading to Sato’s new Verizon IndyCar Series team, Rahal Letterman Lanigan Racing’s, Indianapolis-based shop.
A few social posts from Muroya’s victory and the subsequent celebration are below.
Muroya wasn’t alone among big winners at the Speedway. In the Challenger Class, Melanie Astles of France became the first woman to win a major race at IMS, and is the first female winner in the Red Bull Air Race World Championship.
Nine women have competed in the Indianapolis 500 (Janet Guthrie, Lyn St. James, Sarah Fisher, Danica Patrick, Milka Duno, Simona de Silvestro, Pippa Mann, Ana Beatriz, Katherine Legge) and Mann is the first woman to have been on the pole position at IMS, having done so for the Freedom 100 in 2010 in Indy Lights.
