May 8 (GMM) Red Bull's new alternator supplier is actually McLaren, Germany's Auto Motor und Sport reports.
Italian reports identified that new supplier as 'Tag'.
It seems those reports were actually referring to Techniques d'Avant Garde, or TAG -- the well-known McLaren-affiliated company.
The Auto Motor und Sport headline reads: "Red Bull reliable, thanks to McLaren".
The report said Renault confirmed the news, insisting that - no matter the supplier of components - Red Bull's French engine supplier remains responsible for the adaptation and installation of the alternator.
