It was announced last May that the Japanese firm will rekindle its famous partnership with McLaren next season.
Current power-unit manufacturers Mercedes, Ferrari and Renault all supply several F1 outfits, but McLaren will be Honda’s sole focus in 2015.
“For 2015, McLaren is our only customer,” Arai said during the FIA Friday press conference at the Shanghai International Circuit. “I don’t think about the future, because we want to concentrate on next season.
“If teams want to use our engine or power unit, we can deliver after year 2016 but right now there are no plans.”
He also explained the reasons behind Honda’s decision to return to Formula 1 after a six year absence: “One of the major reasons for our decision was the new regulation introduced this year and that the various environment… I mean green technologies in the new Formula One power unit, as well as the total energy management are both very challenging and significant.
“The new regulation encourages each power unit supplier to pursue the ultimate combustions efficiency and high pressure direct injections, such as many, many new technology. Thus the challenge is to convert each unit of gasoline into energy and this is expected to be reflected on the huge production mode. That’s the reason why.”
He also said Honda’s European F1 base in Milton Keynes will be opened in June, adding: “That factory is to do the engine maintenance for the races and rebuilding the Formula One engine and also to go to the race-track for the trackside service.”
