At the 2025 Japan Mobility Show, Lexus actually envisioned several possible forms a future LS flagship could take someday, some more realistic than others. One was a six-wheeled luxury van; another was a one-seat vehicle with three wheels. But I'd say one of them is much more plausible, and that's the LS Coupe Concept. It's not an actual coupe, though, but rather a big SUV with a sporty coupe-like roofline and a dramatic fastback rear end.
