Lewis Hamilton is concerned by F1 taking on more weight next season following the introduction of the Halo and additional engine management components.
With power unit allowance reduced from four to three units for the entire season, the 2017 world champion and Mercedes driver fears the negative consequences which could accompany the changes.
"I don't like the idea of going to three," Hamilton said, according to the BBC, referring to the decreased number of engines allowed in 2018.
"That sucks. Sprinting is what we are missing in F1.
"The car is going to be a bus next year, it is going to be so heavy, like a NASCAR. The braking distances get longer, the brakes are always on fire, on the limit," he lamented.
"I know it sounds negative but as a racer we want fast, nimble cars where we can attack always every single lap."
Hamilton admitted however that those hopes likely won't materialize anytime soon.
"Unfortunately that is not what we generally have. I had that today but I was coming from a different place. If you look at the front guys, they were managing and that is what we are normally doing.
"I don't think that is too exciting for people to watch," he admitted.
"If you look at the most exciting races, particularly when it rains, we don't have those limitations. I'm not sure cutting down engines is helping it in that direction."
