The American outfit sprung a surprise by revealing the car ahead of the other competitors, like Williams and Red Bull Racing, with a post on the popular social media site.
Bigger. Better. Faster. Lighter.

The team says a lot of the focus on changes to the car have been on overcoming aerodynamic and handling weaknesses that hindered its progress throughout the 2017 season.
In particular, the team wants to create a more stable platform to ensure that its form does not vary to the extremes like it has in the past.
One area where a lot of effort has gone in to, for example, has been weight reduction in a bid to help it use more ballast to help with the set-up.
Team owner Gene Haas said: “We eliminated a lot of the variables where we knew we were weak. We’ve focused on what it’s going to take to get our car to be consistent and close that gap to the top teams.”
Gunther Steiner, team principal, acknowledged that there was little radically new on the car, beyond the changes forced by the shark fin and halo regulation changes.
“The biggest part of the car’s evolution was the addition of the halo,” he said. “It took quite a bit of study by the aerodynamicists, but the designers had to work hard to modify the chassis so the halo could survive the mandated loads.
“The total minimum weight of the car increased because of the halo, and there’s a higher centre of gravity simply because of the halo’s position. But, everyone is in the same boat.
“The regulations stayed pretty stable between 2017 and 2018, so the VF-18 is an evolution of our car from last year. It’s less about reinvention and more about refinement. You see elements we had from last year on the car this year.”
Steiner believes that Haas can make good progress in the constructors’ championship if it learns to extract more from its car on weekends.
“Our 2017 car was actually pretty good, but we didn’t always get the best out of it, and that’s what we aimed to change in 2018,” he explained.
“We got the car as light as possible to carry more ballast. We were able to do a better job of putting the weight where we wanted it.”
The Haas VF-18 has retained the corporate grey, red and black colours of the company, edging back towards the colour scheme it had in its maiden 2016 campaign.
Congratulations to Haas Formula 1 for showcasing their new race car ahead of the other teams. Hopefully the VF-18 is competitive in the upcoming season.
