Christian Horner is hopeful F1's new 2025 engine will be loud and entertain fans while remaining sustainable.
Manufacturers met at the Austrian Grand Prix last weekend to discuss how the future hybrid engines will look. Red Bull were part of those talks as they take over Honda's engine project next season, and Horner wants the noise factor to really be taken into consideration given the current turbo hybrids have been criticised for being too quiet compared to the V10 and V8 engines of the past.
"We see that costs of the current engine are extremely prohibitive," Horner told RacingNews365.com and other members of the media. "It was not thought of when this engine was conceived, and I think there's a fantastic opportunity for what could arguably be the engine for 10 years when it's introduced, to do something a little bit different.
"I think it still needs to address the emotion, the sounds, and yes, of course, it has to tick the sustainable boxes. But, I think it still needs to be entertaining, otherwise we should all go and do Formula E.
"Hopefully the collective minds can come up with something attractive for 2025, or what would be more sensible is do the job properly for 2026."
Horner believes the meeting was positive overall as all the right stakeholders were involved.
"I think it was a constructive dialogue," Horner added. "It's important we find the right solution, both in cost and product, for the future of F1.
"I think all the right stakeholders are involved in that discussion, and it's important to work collectively for the benefit of the sport.”
