Toro Rosso have released the first images of their 2019 vehicle to kick off Formula 1's eagerly-anticipated "launch week".
Toro Rosso linked up with Honda in 2018 but compromised some of its Grands Prix for the sake of the Japanese marque's development programme, and concurrently struggled with its own chassis progress.
Tost said the new arrangement - which Toro Rosso last used in 2008, when it effectively had an entire vehicle from Red Bull before that practice was banned - would "leave more time for our technical working groups to focus more on the details".
The new vehicle features the wider front and rear wings that have been mandated this season by F1's rule-makers in an attempt to make the racing closer by allowing cars to follow each other more easily.
"If I was a dictator, which I never was, I would take the FOM money and give - to just name a figure - $60 million to each team".
"Actually, this is the philosophy we followed until 2010 when the other competitors voted for a rule change", said team boss Franz Tost. They know what they're doing.
Toro Rosso's new auto features many parts that were used on the 2018 Red Bull. I think we're looking good and I feel that everyone is motivated and focused.
But the Red Bull junior outfit, who finished ninth last season, do have an all-new driver pairing in Daniil Kvyat and Alexander Albon for the upcoming campaign. However, there are fewer variables, and I see this as an opportunity.
For instance, the entire Honda-powered rear end of the new Toro Rosso will be identical to what is run by Red Bull. However there were encouraging signs of potential in the Toro Rosso-Honda package, such as Pierre Gasly's excellent fourth place in Bahrain, and the team's sixth and seventh on the grid at Suzuka when Honda introduced a significant power unit upgrade.
Honda chief Toyoharu Tanabe said: "In simple terms, our aim is to achieve better results than in 2018 for both teams". The Englishman is expected to start work at his new team later this year.
Toro Rosso finished ninth in the constructors' championship a year ago and achieved a best result of fourth place in the Bahrain Grand Prix thanks to Pierre Gasly.
