Toro Rosso have unveiled their 2019 Formula 1 vehicle, saying it owes a lot to last year's Red Bull.
"Although the timescale for some of these changes was tight, and in the short term these changes have generated some extra work, the development rate of the 2019 auto is now strong and responding well to the aero developments being evaluated in CFD and the wind tunnel".
"In regards to our performance, as is always the case before the start of a season, it's too early to say and we don't want to set a specific target - at least not now", team principal Franz Tost said.
Following on from the Haas release last week, the new auto showcases the 2019 regulation changes that include a simplified front wing and larger rear wing, as well as tweaks to the brake ducts.
On the driver front, Red Bull has brought back to the fray 24-year-old Daniil Kvyat, who endured several gyrations between Red Bull Racing and Toro Rosso between 2014 and 2017, when he left the Faenza team before the end of that season.
"A number of changes have been put in place regarding how we develop the 2019 auto, including the approach to how we develop the vehicle aerodynamically", Egginton said. The pair make up an intriguing line-up for the Red Bull junior team, having both been dropped from Red Bull's programme in the past. I think we're looking good and I feel that everyone is motivated and focused. "I'm just focused on myself and let's see how it all goes".
Their 2018 campaign was heavily compromised by grid penalties - no team took more than Toro Rosso - but there was also marked improvement in the Honda power unit towards the end of the season. "For our partnership with Toro Rosso, that means finishing higher up in the Constructors' Championship, scoring more points, running more reliably and, maybe even repeating last year's Bahrain result or doing better".
His first ended when he was promoted to Red Bull in 2015 to replace Sebastian Vettel, but he returned just over a year later after struggling to impress.
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".
Red Bull's junior team are this year taking advantage of new rules allowing teams to buy parts from rivals.
