Driver criticism overshadowed Formula One’s second pre-season test in Bahrain.
Max Verstappen attacked the new regulations and called the cars “anti-racing”.
He said complex energy management makes them “not fun to drive”.
He again hinted he could leave the sport if he stops enjoying it.
Lewis Hamilton voiced similar concerns.
He said the systems are so complicated that fans will struggle to understand them.
He added that drivers now need extensive technical knowledge to operate the cars.
The new rules introduce engines with nearly equal electric and combustion power.
They also bring new chassis, tyres and fully sustainable fuel.
Testing times remained inconclusive because teams focused on learning the cars.
Mercedes set the fastest laps with Kimi Antonelli and George Russell.
Ferrari showed strong race pace with Hamilton and Charles Leclerc.
McLaren looked competitive with Lando Norris and Oscar Piastri.
Verstappen finished seventh but displayed exceptional straight-line speed for Red Bull Racing.
Norris dismissed Verstappen’s complaints and said the cars remain enjoyable.
Toto Wolff claimed Mercedes set the benchmark.
Red Bull insisted it was not the fastest and accused rivals of hiding performance.
Rival teams also questioned Mercedes over a possible engine loophole.
The FIA plans to address the issue before Melbourne.
Aston Martin endured a difficult test.
Lance Stroll criticised the engine, balance and grip.
The new car by Adrian Newey remained several seconds off the pace.
