Max Verstappen says he's not looking forward to racing with the "very ugly" halo on his Red Bull car this season ahead of its unveiling next week.
Red Bull's RB14 will be shown off on Monday and, like every 2018 car, will feature the FIA's mandated head protection device dubbed the halo.
Although eager to seeing how competitive his new car will be and where it will stack up against Red Bull's rivals, Verstappen said the introduction of the halo would tarnish the reveal of his and team-mate Daniel Ricciardo's new car.
"The halo, that will be very ugly," said the Dutchman. "I am not looking forward to that!
"In general I hope the car will look great and hopefully it is fast. Hopefully it is a good step forward and we have got straight away a good car for the beginning of the year, so we are not really chasing, like we did last year. That is the most important thing for us."
The additional weight of the halo could penalise taller and heavier drivers as the device weighs around 11kg in total with fixings and mountings, and that's a concern for Verstappen.
"The halo is quite heavy, it will be more than six kilos [the halo itself excluding fixings], it is definitely not favourable for me," he added.
"But I am not going to adjust my training for it, because otherwise I won't feel well during the races. Especially for me being a taller driver and also a bit of a heavier driver than most, it is definitely not ideal."
Verstappen finished sixth in last year's championship, taking victories in Malaysia and Mexico.
