Toyota Mirai

The Toyota Mirai arrives as a bold, futuristic saloon that turns heads with sleek, almost sci‑fi styling and a cabin that feels more lounge than cockpit. It trades petrol fuss for a whisper‑quiet hydrogen setup that delivers composed, effortless progress and makes long-distance cruising a relaxed pleasure — a compelling choice if you want cutting-edge eco tech without sacrificing comfort.

Great car, I switched from a Lexus NX300h F-Sport, and in terms of comfort the Mirai wins.
