Red Bull's new engine proved dominant during Bahrain pre-season testing, but drivers are deeply divided over whether the revised cars retain the essence of Formula 1. Four-time champion Max Verstappen criticized the energy-stingy regulations, stating the cars force drivers into a 'management exercise' where inputs heavily impact energy use, making 'pure driving' impossible. Lando Norris countered, calling the cars 'a lot of fun' and suggesting Verstappen race elsewhere if dissatisfied.

Mercedes' George Russell offered a middle ground, noting the cars might yield more chaotic racing but could also be less exciting. Veteran Fernando Alonso acknowledged Verstappen's point about energy recovery systems fundamentally changing driving but urged caution, stating the sport still 'loves motor racing' and competition. The testing also highlighted a potential performance gap, with rivals suggesting Red Bull's engine deployment is 'pretty scary' and could give them an edge at the season opener.

However, Mercedes disputes this, claiming top teams like Ferrari and McLaren are ahead, while Ferrari's Charles Leclerc believes the gap is manageable. A simmering row over Mercedes' engine design, accused of exploiting a rule loophole on compression ratios, threatens to disrupt the season before it starts, with the FIA expected to rule soon.
