Helmut Marko says Renault should focus its efforts on the Red Bull Racing team if it wants success in 2016, adding the manufacturer is unlikely to achieve anything of note with the ex-Lotus set up.
Having focused its efforts as an engine supplier in recent years, earning four titles with Red Bull between 2010 and 2013, Renault returns to F1 as a constructor in 2016 after completing a buy-out of the Lotus F1 team.
Renault's decision to come back was preluded by a breaking down in relations with Red Bull, which felt the French firm had failed to deliver a strong enough package following the change in engine regulations. That said, Renault contested it never received enough credit from Red Bull for its role in those four titles.
However, though Red Bull actively sought a new engine supplier for 2016, its failure to secure a deal would see it retain Renault power for this year, albeit rebranded as TAG-Heuer.
Even so, despite the ongoing co-operation, the fractious relationship between the two parties shows little sign of abating as Red Bull Motorsport advisor Marko dismissed Renault's team as unlikely to achieve anything in 2016 and that it should prioritise Red Bull as a result.
"We are contractually secure and we have the same status," he told the Salzburg Nachrichten newspaper. "When I look at the current Lotus (Renault) team, if Renault are clever, they should concentrate on us because with that team and drivers they will achieve nothing at all.”
Marko also says he doesn't expect to see much change in the F1 hierarchy this year, saying Mercedes will continue to dominate because the regulations don't allow struggling teams to make up ground.
“If nothing changes, there will be the usual Mercedes-superiority. The current regulations are unfortunately so restrictive that you cannot come from behind."
