"We are not making any major changes to our engine system. It seems that some other suppliers are considering that, but our base system will be similar to the one we used in 2020."
This is a big surprise for me. So the increase of 40HP may be really just a rumour!?
But on the other hand: what is the "base system"? A V6 with a split turbo layout, and an MGU-H and an MGU-K
The 40HP increase should be considered a rumor as there is no concrete data saying so. It's "word of the paddock" from Jack Plooij and the understanding is that the Honda PU was down 30HP to the Mercedes in 2020.
With regard to the next Honda PU here's what Tanabe said at Abu Dhabi :
2021年のF1パワーユニットの開発について質問された田辺豊治は
「我々は過去の自分たちの弱点について多くのことを学びました。エンジン、ICEだけでなく、ERSを含めたすべてのエリアを改善し、来年シーズンはPUとして強力なパッケージとして作りたいと考えています」と最終戦 F1アブダビGPの記者会見で語った。
「内燃エンジンに関してはすべてが新しいわけではありませんが、ほとんど新しいものです。ハイブリッドシステムに関しても、昨年からアップデートされたものもあれば、新しいパーツもあります」
「アップデートと新しいパーツが混在していると言えますが、エンジンは完全に新しいわけではありません。ただし、ほとんどのパーツは新しいです」
"We have, looking back on our past weaknesses, learned much about it. As for the engine, with not just the ICE but also including an improvement with the ERS, we think the PU for next season will make a powerful package.
The ICE won't necessarily be entirely all-new, but it is pretty much new. The hybrid system, with this past year's updates considered, will also have brand new parts.
While I can say there is a mix of updated and brand new parts, it's not like the engine is completely new. However, much of the parts are new".

Obviously the parts that are "new" I surmise are new designs or materials with efficiencies and durability improvements. Regarding performance upgrades we'll likely not know what improvements are being made but there is a belief that Honda is utilizing a "clever" interpretation of the regulations with off-throttle fuel burning to prolong electrical energy generation which is being called "a secret weapon". This system introduced last year apparently had no issues with regard to regulation scrutiny so there likely may be improvements in this area. It's been discussed here before but whether or not this actually provides an advantage remains to be seen. It's mentioned in this other article below.
