Look at Century and Crown, and GR products vs. F Products as points of comparison.
Lexus is being repositioned into an electric sub brand project more than a global luxury brand on par with Mercedes, BMW, et al.
I think there are ways this can work for Lexus, but it's going to be very different from what we have known previously. The future is Toyota first with Lexus as an afterthought -- we're already living in that reality, but it's going to get a lot worse before it gets better.
My opinion is that as Japan has consolidated control and taken decision making away from the regions, they're rolling out a more JDM-esque strategy across the globe where Crown is similar to Lexus and Century is above Lexus... so then, what really is the point of Lexus? It no longer fits into the traditional lineup of:
- Toyota: Mainstream
- Crown: Premium
- Century: Super Luxury
- GR: Motorsports and racing
The only way to keep Lexus relevant was to make it completely different: electric. However, what that means 10-15 years from now when most everything in the Toyota, Crown, and Century lineups are also electric? No idea. Lexus has been starved for resources and product while Toyota, Crown, Century, and GR have all been completely renewed and updated. I don't even think tea leaves are necessary - the writing is on the wall: The old Lexus, the one that brought all of us here in the first place, is dead.
To the point at hand, when the GR GT3 Concept was released, it didn't have a brand on the hood but it was released by "Toyota Gazoo Racing." There was a photo from a dealer meeting of it wearing a Lexus badge, and that was discussed at one point, but keep in mind the only car Lexus has ever publicly referenced as a follow up to the LFA is the Electrified Sport Concept -- never the GR GT3 Concept. The GR GT3 is a GR car. Whatever Lexus "LFA" comes next will be electric -- Lexus has explicitly stated that.
