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 called the changes “anti-racing” and compared the feeling to “Formula E on steroids”.
He again suggested he could leave the sport if he stops enjoying it.
Lewis Hamilton voiced similar concerns.
He said the systems are extremely complex and difficult for fans to follow.
The new rules introduce different engines, chassis, tyres and fully sustainable fuel.
Power now comes almost equally from combustion and electric sources.
Testing times gave only limited clues about performance.
Mercedes led the timesheets with Kimi Antonelli and George Russell.
Ferrari and McLaren also showed strong pace.
Verstappen finished seventh but demonstrated impressive straight-line speed for Red Bull Racing.
Lando Norris rejected Verstappen’s criticism.
He said the cars are still enjoyable and that it is too early to judge.
Teams also played down their own chances in typical testing gamesmanship.
A dispute over a possible Mercedes engine loophole continued in the background.
The FIA wants the issue resolved before the season opener in Melbourne.
Aston Martin endured a difficult test.
Lance Stroll criticised the engine, balance and grip.
The team’s new car currently appears far off the leading pace.
