Christian Horner has confirmed that Red Bull's Formula 1 plans for 2018 will not be affected by any decision sister team Toro Rosso takes over its en🔴gine supply for next 🔴season as talks with Honda continue.

Toro Rosso is currently engaged in discussions over a possible link-up with Honda for 2018, swapping its Renault engine supply with McLaren as the British marque looks for a wa🌄y out of its existing deal.

While no announcement has been forthcoming, it has been repo🎃rted that Toro Rosso set a deadline on Sunday night for any deal to be struck with Honda, failing which it would continue to work with Renault.

Despite he🅠ading up the s🤪enior team to Toro Rosso, Horner has been largely on the sidelines in discussions, admitting that any decision will have zero impact on Red Bull.

"To me itꦡ doesn’t matter what engine Toro Rosso are💫 on," Horner said.

"They’ve been on a d🍬ifferent power unit for many years🌄 previously, so whether it’s a Renault or a Honda engine doesn’t affect Red Bull Racing at all.

"I can’t offer you any update. The key piece in the whole jigs🅺aw is the McLaren-Honda situation.

"I’m not sure what’s the latest they’ve said on it,🍌 but one would assume their position is fairly imminent."

Horner acknowledged last weekend that a deal between Toro Rosso and Honda would give Red B༒ull an option for an alternative engine supply d💞own the line should its own struggles with Renault continue.

Toro Rosso has only shared an engine supply with Red Bull for two full seasons in F1, having mainly worked with Ferrari since joining ༒the grid in 2006.
