Note that Mercedes don’t think they’ll claw back the downforce to get to 2020 lap times: https://www.motorsport.com/f1/news/2020 ... =widget-22
This is interesting to me because I suspect it may help to get a little more compression for the field - I.e. those who were already less optimised in 2020 will lose less due to these changes.
I think the carryover of the chassis from 20 to 21 will help RB since they always seem to struggle to understand their new car and so that weak point will be taken away. Ferrari were SO far from optimised this year - running a car designed for a more powerful engine, apparently with some kind of gearbox flex and rear suspension issues - that I wouldn’t be surprised if they were actually able to improve their pace relative to last year (especially if they find ~50 hp as has been suggested).
All that said, Mercedes: a) stopped developing 2020 car first, and so have spent longest adapting to these new regs b) apparently compromised their Abu Dhabi race so they could run parts in the post race test, allowing them to learn more c) have a pretty impressive track record in adapting to these changes.
So I still see the pecking order as follows:
Mercedes
RB - but closer; Max within a couple of tenths and Sergio close enough to try alternate strategy
Ferrari - within half a second of the pace, which will still be a big gain and occasionally on the podium on sheer pace
Aston - with the ‘free’ tokens, a solid chassis and a reinvigorated Seb, the Vettel car may be close to the top 3
McLaren/Alpine - for Mclaren, they’ll gain from the engine but have to use their tokens to install it, cancelling out much of the gain (they still may score more than Aston due to the Stroll car being less consistent); for Alpine the Alonso car will be especially consistent and I suspect they’ll build on their decent platform to consistently score good points but will be laser-focused in 2022
Torro Rosso - Tsunoda and Gasly will be a strong pairing and the Honda taking its final big jump will help them early season
Haas - will benefit from Ferrari’s big engine and rear changes but Mick will score more than Mazepin, who will be a one season wonder
Williams/Alfa - I think they’ll both be close to the Haas - and Russell may often outqualify Mazepin - but ultimately the Haas will be a better race car. Kimi’s pace will continue to decline (and will again be out qualified by Gio) but Giovanazzi will continue to struggle relative to Kimi in races. They’ll both be out for 2022
