The team enters the new season with the same determination, drive and passion, but knows there is a long and challenging journey ahead.
"Both our drivers seem reasonably happy with our new car, but it remains yet to be seen how well it performs when driven in anger," Toto added. "The reduction in the number of power unit components means that reliability will again play an important role in 2018.
"Our reliability in testing looked good but we need to be careful to draw any conclusions from that - despite getting some good mileage with the new car in Barcelona, many of its components have not even come close to the life they need to complete during the season.
"We will tackle this new season with the same dedication, team spirit and energy that has made us strong in the past. Each of us has the mindset that last year's Championships belong in the past; yesterday's trophies don't win today's games.
"A new season feels like climbing Mount Everest - we've done it successfully in the past, but we're only in the base camp at the moment. It will be a tough journey, with the same target, but different challenges to master along the way. Right now, we start this long season on zero points like every one of our rivals. And we have to give it everything to be successful again this year."
