We are at the tail end of new ice engines being developed. R&D is quickly being given over to full ev s. Even though there is still a lot of activity for hybrids, it's only a temporary bridge until cheaper better batteries with faster charging and better ev supporting infrastructure gets built out. There is currently a bottle neck in battery production but that will go away as factories ramp up to meet demand.
Luxury brands like the ones you mentioned will be the first to go full ev, as their customers most appreciate the NVH and power characteristics of electrics and are best able to afford (at this stage ) the higher cost. Many companies have already publicly stated their plans to do so. Adding to this, the governments in most countries continue to ratchet up the pressure with ev incentives and ice disincentives. There may not be many ice alternatives available in this category past 2025/2026 or in all categories past 2030.
