"Nothing has changed in terms of the design process of laying the vehicle out", said Toro Rosso's deputy technical director Jody Egginton, as the team unveiled its 2019 auto.
Tost said the new arrangement - which Toro Rosso last used in 2008, when it effectively had an entire auto from Red Bull before that practice was banned - would "leave more time for our technical working groups to focus more on the details". However, if fans were hoping for a striking livery, they will be sorely disappointed.
"Nothing has changed in terms of the design process of laying the auto out, we just have a few less variables to play with", Egginton explained. Hopefully, the vehicle will be quick and produce decent results for Daniil Kvyat and Alexander Albon.
US-based Haas have led on this approach since 2016 and Toro Rosso see it as a way to better use resources.
Toro Rosso revealed their STR14 yesterday and are ready for winter testing to begin on February the 18th. Daniil Kvyat first drove for the team five years ago and is making his return after spending 2018 as one of Ferrari's simulator drivers.
The Russian had initially been promoted from Toro Rosso to Red Bull for 2014 but was demoted back again after four races in 2016 in a swap with Max Verstappen before being dropped altogether 18 months later.
"Like everyone else, we are working hard to put the best package together and the best thing I can do for myself is to work as hard as possible on myself and on my performance." said Kvyat.
He said: "So, both teams get half the 2018 guys and half new Honda personnel". Me and my engineering crew will do everything we can to squeeze the maximum out of the package we're given by the team.
The junior Red Bull squad finished ninth in the championship past year, ahead of only the struggling Williams outfit. I think we're looking good and I feel that everyone is motivated and focused.
Kvyat's team mate is newcomer Alexander Albon, who finished third in Formula Two a year ago behind fellow 2019 F1 debutants George Russell and Lando Norris. "I'm just focused on myself and let's see how it all goes".
