Christian Horner is disappointed by the decision of engine supplier Honda to leave Formula 1 after 2021.

The Red Bull team boss realizes that his team faces a major challenge.

"We are disappointed that our partnership with Honda is coming to an end," Horner said on the Red Bull website.

"At the same time, we are extremely proud of our joint success. We have achieved five victories together in recent years and have been on the podium fifteen times."

Despite the four victories of Verstappen and one of AlphaTauri driver Pierre Gasly with a Honda engine, Red Bull, together with the Japanese manufacturer, failed to close the gap with the for years dominant Mercedes.

Honda gave the reason for the departure on Friday that the company wants to be CO2 neutral by 2050.

"We understand that it must have been a very difficult decision for Honda to leave the sport," said Horner.

"We respect the underlying reason. Within the automotive industry, the focus is currently shifting."

After a turbulent collaboration, Red Bull left engine supplier Renault at the end of 2017.

The French company is the only surviving engine builder in Formula 1 with Mercedes and Ferrari.

Horner guarantees Red Bull's future in F1

Because the two competitors are unlikely to want to give the engine to Red Bull, a return to Renault seems a realistic option.

"We are now facing a major challenge," says Horner.

"The team has been in this situation more often and we are prepared to find a good solution. We are looking for the best power source for 2022 and beyond."

Horner guarantees that Red Bull itself will remain active in Formula 1, at least until 2025. "We recently signed the Concorde Agreement. We look forward to a new era of innovation, development and success."

The team boss hopes to be able to celebrate that success with Honda in the next fifteen months.

"I want to thank them for their extraordinary commitment and commitment. Our shared goals for the rest of 2020 and 2021 will not change. We will continue to fight for victories."
