Saloon
Toyota's hydrogen fuel cell saloon — the first mass-production hydrogen car. UK got the awkward Mk1 (2015-2020) in tiny numbers, then the much sharper Mk2 (2021-Present) on the GA-L platform shared with Lexus LS. Mk1: 154 bhp e-motor, FWD, claimed 312 miles per fill. Mk2: 180 bhp e-motor, RWD, three hydrogen tanks for ~400-mile range. Both fill in 3-5 minutes at one of about a dozen UK hydrogen stations. Mk2 is the better car — proper rear-drive saloon, smart cabin, but the UK hydrogen network is the limiting factor. Lease-only for most buyers; a curiosity rather than a recommendation. The infrastructure isn't there yet.
