Newey, whose top-flight tenure started with a stint at Lola in 1986, has designed grand prix cars that have so far won 12 constructorsâ titles and 12 driversâ crowns for three teams.
Notably, Williams scored 10 wins - including six 1-2s - from 16 GPs in 1992 and 12 victories in 1996.
After moving to Red Bull as chief technical officer in 2006, Newey oversaw machines that won 12 races in 2011 and clocked 13 triumphs in 2013 as the calendar grew to 19 rounds.
But speaking on F1âs Beyond The Grid podcast, Newey reckons the consistency achieved by Max Verstappen and Sergio Perez aboard the RB19 this season still stands proud.
Newey, whose episode was recorded in Singapore when the Red Bull count was 14 wins, said: âThis has been our biggest run of success that Iâve certainly ever experienced.
âIâve been fortunate enough to have been involved in cars that have been dominant in the past, but weâve never had this level of consistency.
âPeople might think it now that everything is kind of guaranteed and itâll be smooth. The reality is, so many things can go wrong in a race.
âActually getting two cars to the finish, preferably both of them near the front week after week, itâs a difficult challenge because of all the elements that can go wrong: reliability, accidents, strategy, performance obviously.
âSo, to achieve this, I think, is a real tribute to everybody.â
Critical to the success of the RB19 has been its wide operating window that enables the car to adapt to a variety of circuits.
This compares to the sensitive Mercedes âzeropodâ architecture that debuted with the W13 in 2022, a design guided by the peak downforce numbers the team could simulate.
Despite the heavily contrasting concept from a team that had just won eight constructorsâ titles in succession, Newey said he had a âgut instinctâ not to consume restrictions under the FIA cost cap to study the Mercedes solution and compare it to the one devised by Red Bull.
He said: âEven with all the tools we have now, there still has to be a degree of gut [instinct].
âThe reality is, even before the cost cap, we were still resource and people limited.
âWe have never had the capacity to research endless different paths in great detail.
âIf you take a recent example, obviously with last yearâs car we took an aerodynamic direction with the sidepod and design and the concept of the car, which was almost polar opposite to what Mercedes did.
âMercedes showed flashes of competitiveness last year. They obviously won in Brazil.
âThen youâre faced with a choice of âDo we start to research Mercedes in case weâve missed something or do we stick with what weâre doing?â Gut feeling was stick with what weâre doing.â
