I'd like to see Jag go 100% BEV with high performance and luxury, focusing on coupes, saloons and estates; that would leave LR free to continue with ICE engined SUVs by generating emissions credits to offset that development. While people aren't buying ICE powered sedans, they are buying EV sedans and crossovers. Let the Evoque and Velar be the tweener models for the JLR brand and offer EV drivetrains, and maybe offer a high-end EV drivetrain option for the FFRR.
Hydrogen is a show. It's something to throw some token R&D dollars at and then advertise with, but when you look at what will be required to make it work large-scale, it's a generation or more off, maybe even never if high-energy-density batteries mature a bit more. EV infrastructure is easier to establish than hydrogen infrastructure since electricity already goes everywhere; you'd have to retool or re-create the entire petroleum extraction, storage, shipping, and delivery infrastructure to make hydrogen viable as a commodity fuel.
