Christian Horner was quick to play down Toto Wolff's suggestions that Red Bull's investments in their own engine could open the door for Volkswagen to enter the sport, stating the Mercedes boss seems to always know other people's business.
The Milton Keynes outfit announced back in February that they will be forming their own engine division called Red Bull powertrains. The team have shown they mean business after signing Ben Hodgkinson, a senior figure at Mercedes, to head the operation.
That prompted Wolff to suggest Red Bull's strategy could see them link up with a Volkswagen brand like Porsche or Audi, but Horner was quick to state there are no ongoing talks regarding the name of the power unit.
"Toto always likes to think he knows what's going on in other people's business, but he needs to think about his own," Horner told Sky Sports. "We're building a fantastic facility, we've got some great talent coming into the facility.
"It's going to be on campus, it's going to be integrated fully with the chassis side of the business. We'll be the only team other than Ferrari to have that. And of course what the engine is called is another matter.
"At the moment, there's no discussions in place. It's focused on being a Red Bull engine. But you know, of course, that engine could be called anything in the future, but to have it integrated fully into Milton Keynes is tremendously exciting."
