So the V6 Hybrid will be here for another 5 years. But in 2021 a new engine has to be chosen and what will it be like? This is what i think:It means that the plans for a threatened standard engine will be shelved and hybrid turbos will be the default power unit for F1 until 2020. All teams are guaranteed to have an engine so there will be no repeat of Red Bull’s situation last season.
1. Stronger MGU-K.
Electric cars are already coming fast, the Tesla 3 is sold out before the 1st one has rolled out the factory. An even cheaper model is in development. So electric propulsion has be a bigger part of the new engine. MGU-K should be doubled or ecen trippled to approx. 300Kw.
2. Smaller ICE
To prevent +1000hp powerunits, the ICE will have to be smaller. Porsche built a great V4 or maybe cut the V6 in half, to an inline 3 cilinder. Anyway the next generation f1 will probably have smaller then 1L displacement.
3. New turbo
The hybrid turbo is an important part of the current hightech engine and recovered energy feeds the MGU-K. But also a big problem to implement by manufacturers and it makes the PU very expensive and complex. So will it be there in 2021? I'm not so sure.
