Max Verstappen criticised Formula One’s new regulations after pre-season testing in Bahrain.
He said the heavy focus on energy management makes the cars “not fun to drive”.
He described the system as “Formula E on steroids” and “anti-racing”.
He repeated that he could leave the sport if he stops enjoying it.
Lewis Hamilton voiced similar concerns.
He called the new technology extremely complex and difficult for fans to follow.
The rules introduce new engines, chassis, tyres and fully sustainable fuel.
Power now comes almost equally from combustion and electric systems.
Testing times offered few clear answers.
Mercedes led the standings with George Russell and Kimi Antonelli.
Ferrari and McLaren also showed strong pace.

Lando Norris rejected Verstappen’s criticism.
He said the cars are still enjoyable and that Verstappen will keep fighting to win.
Toto Wolff claimed Mercedes set the performance benchmark.
Red Bull played down its own chances, while Verstappen accused Mercedes of hiding speed.
Rivals also questioned Mercedes over a possible engine loophole.
The FIA will discuss the issue before the Melbourne opener.
Aston Martin endured a difficult test.
Lance Stroll criticised the engine, balance and grip.
The team’s new car remains several seconds off the leading pace.
