Christian Horner made an interesting point about the future of Formula 1 during last Friday’s team principals’ press conference for the British Grand Prix at Silverstone.

“F1 is effectively at a crossroads with the new regulations, which theoretically come in 2021 and there will probably be an eight- to ten-year life on [the next generation] engines, so what we are looking at actually is the sport’s relevance pretty much up to 2030,” said Red Bull Racing’s chief. “Now, by 2030 how many people are actually going to be driving [road] cars?

“Are they going to be autonomous? Are they going to be electric? The world is changing so fast in that sector.

“So Formula 1 has some serious questions that it needs to answer today in the choice it makes for the engine for the future. What is its primary purpose? Is it technology or is it a sport and entertainment, and man and machine at the absolute limit?”

This got me thinking about whether F1 still needs cutting-edge automotive tech to remain the pinnacle of racing.
