Horner: F1 could follow IndyCar’s lead, use V6 twin-turbo engines

Formula 1 could be set to follow IndyCar’s lead and introduce V6 twin-turbo engines upon the planned regulation change in 2021, according to Red Bull team boss Christian Horner.

F1 has raced with V6 turbo hybrid power units since 2014 in a bid to make the sport more road-relevant and efficient, with cars racing on 30 per cent less fuel and recording faster times than ever.

However, the reduced sound of the power units compared to their V8 and V10 predecessors, combined with their complexity and cost has led F1’s bosses to push for a change in specification for 2021.

Meetings have already taken place with a number of manufacturers both inside and outside of the sport in a bid to define F1’s future engine direction, with various avenues being explored.

While Horner would like to see F1 return to normally-aspirated V8 or V10 engines used in the past, he believes a more realistic option could yield inspiration from IndyCar.

“I doubt we will go back to normally aspirated, despite it being my wish. We will end up with a V6 twin-turbo I believe,” Horner told reporters in Hungary, as quoted by crash.net.

“But the acoustics are a key aspect of what has been put on the table because when this engine was introduced the costs or the attractiveness by noise were fundamental parts of what the engine should be.”

The FIA has outlined its main criteria for F1’s future power options, centering on four areas:

  • a desire to maintain F1 as the pinnacle of motor sport technology, and as a laboratory for developing technology that is relevant to road cars
  • striving for future power units to be powerful, while becoming simpler and less costly to develop and produce
  • improving the sound of the power units
  • a desire to allow drivers to drive harder at all times.

IndyCar introduced its current engine specification back in 2012, and, in a rather neat coincidence, is also able to revise its power options for 2021.
