Last year, the world champion team was dogged by a recurring reliability problem with its alternators, supplied by Italian company Magneti Marelli.

"I want Renault to separate from its supplier Magneti Marelli and use someone else," team owner Dietrich Mateschitz declared last September.

Italiaracing, adding that Magneti Marelli continues to supply alternators to Lotus, claims Red Bull's new supplier in 2013 is Tag.
