Jun.23 (GMM/Inautonews.com) Mercedes has refused to follow in Ferrari’s footsteps in offering to supply engines to Red Bull.

At the weekend, Ferrari president Sergio Marchionne said the Italian marque is willing to take struggling Renault-powered Red Bull on board as a customer.

The same offer, however, has not been forthcoming from Mercedes, whose own turbo V6 ‘power unit’ is clearly the best in the pitlane.

“We are at full capacity,” Mercedes’ Toto Wolff told the Austrian news agency APA.

Indeed, as well as leading the field with its works team, Mercedes supplies customer engines to Williams, Lotus and Force India.

“Four teams including our own is the maximum,” Wolff confirmed. “So at the moment we are happy with that.”

However, it might also be argued that Mercedes is simply not willing to help Red Bull – the dominant world champions of 2010 through 2013 – to get back to the top of F1.

“There are many reasons,” Wolff admitted.
