Formula 1’s next set of engine regulations could arrive alongside a significant change in the chassis rules which would result in cars with much less drag.
Horner stressed the top priority for the next engine formula, currently due to arrive in 2025, is making them cheaper than the current V6 hybrid turbos, introduced in 2014.
“There’s a few scenarios to look at but the most important factor was to focus on the costs,” he said. “The cost of production, the cost of the materials of the engine to reduce the enormous burden that there is currently on the manufacturers and indeed, any engine manufacturer contemplating coming into Formula 1.
“The first thing that was missed with the current engine, the one thing that was never discussed, was what is that cost? Which is sensitive to all of those stakeholders. So I think that that is effective.
“Can that be done with the current engine, with the current architecture? Does it necessitate a new engine, does that need a new architecture and what does that look like? So there’s working groups that are going through that process at the moment. The target is still ’25, is ’26, however, more realistic.”
Formula 1 will radically overhaul its chassis regulations next year in a bid to make the field more competitive and encourage closer racing. However the arrival of new power units may mean further chassis changes follow within a few years, said Horner.
“What you can’t ignore is its integration with the chassis. This is assuming the chassis has a low-drag characteristics so effectively DRS won’t exist, they will be incredibly efficient cars on the straights.
“What will the tow effect be, how will that affect racing? What will be the recovery rate, potentially, with a bigger battery cell and so on. So there’s many [variables] that need to be fully looked at, but also the bigger picture of what is the right direction for Formula 1.
“I think there are elements of alignment that is close and I think there’s other differing views that will get thrashed out over the coming weeks.”
