Toto Wolff has mocked Christian Horner for being "frightened" of the incoming package of F1 rule changes in 2026.
The planned changes will bring in an increased reliance on batteries, with a 50/50 split between combustion engine and electric power production. But Red Bull boss Horner has voiced fears that the plans could backfire, leaving cars unable to run flat out.
He has made his concerns clear in both F1 Commission and team principal meetings. The Red Bull team principal has suggested that the new-look power units will rapidly run out of electric power on straights.
