Verstappen and Red Bull impressed the rest of the paddock with their pace and energy deployment, but the Dutchman says he was more concerned with what the new generation of cars is like to drive, with an even bigger focus on energy management.
"To drive [they are] not a lot of fun, to be honest," he said. "I would say the right word is management. It's not very Formula 1-like. It feels a bit more like Formula E on steroids. But the rules are the same for everyone, so you have to deal with that.
"As a pure driver, I enjoy driving flat out and at the moment, you cannot drive like that. There's a lot going on. A lot of what you do as a driver, in terms of inputs, has a massive effect on the energy side of things. For me, that's just not Formula 1. Maybe it's then better to drive Formula E, right? Because that's all about energy, efficiency and management. "We're energy poor. I just want normal driving, just how it should be without having to [say]: 'Oh, if I brake a bit longer or less or more, or one gear up or down.' It so heavily impacts the performance on the straights. Plus, the grip at the moment is quite low with these tyres and the car configuration. It is a big step back to how it was."
He added: "Honestly, the proportion of the car looks good, I think. That's not the problem. It's just everything else that is a bit, for me, anti-racing.
"Probably people will not be happy with me saying this right now. But I am outspoken and why am I not allowed to say what I think of my race car? I can't help that.
"I mean, I didn't write the regulation. If it was, I think, up to non-political aspects of making a regulation, I think, anyway, the car would have probably have looked very different."
Verstappen has a contract with Red Bull until the end of 2028 and, having grown frustrated by various aspects of F1 in recent years including the rules direction, has openly talked about the prospect of walking away from F1 at that point.
"A winning car for me doesn't matter," said Verstappen of whether Red Bull winning under these rules would help his enjoyment. "It needs to be fun to drive as well, at this stage of my career.
"I am course also exploring other things outside of Formula 1 to have fun at. I know that we're stuck with this regulation for quite a while. So, yeah, let's see."
Verstappen did say it pained him to be so frank in his views out of respect for the work his team and the power unit division at Red Bull Powertrains had done, with both the car and engine appearing to be in good shape so far - the brand-new engine department even defying expectations.
"On the other hand, I also know how much work has been going on in the background," he added. "Also from the engine side, for the guys. So, it's not always the nicest thing to say. But I also want to be realistic as a driver, the feeling.
"I also know what is at stake with the team; our own engine and seeing the excitement of the people. Of course, when I sit in the car, I will always give it my very best. They know that. Excitement level is not so high to drive."
