how long Renault working on 2021 engine? The article says "for years" any idea how long they are concentrating new engine?
Since 2018, so 2 years.
I would wager
they have been working on it intensively since 2019 mid? Since they had to fix those conrod issues in 2019 early season. Very possible concept planning and R&D have been going on even longer. Since they probably have had only optimization and reliability upgrades which also bring performance since 2019 mid.
I would presume that at some point in the 2019 they moved people to start working on the new PU and left some for reliability upgrades.
Little after the forced closure at the end of summer 2019, Cyril announced some reliability upgrades for the last PU of 2019 then nothing till 2021.
It didn't become know till this year that they were working on a whole new ICE/turbo/MGU-H/compressor. They were also still interested in a PU freeze in late 2019/early 2020. I presume once they gave the go ahead and started spending serious money on it, they switched to against the freeze.
First pictures of new PU are seen from Alonso's visit to Viry Châtillon in September. At that point, the PU is on the dyno. But there are pictures of Renault tinkering with front compressor on the PU on the power unit thread all the way back to 2017.
