The compact crossover is the rumored candidate partly because Mercedes feels the cost of the powertrain means it only makes commercial sense in more expensive vehicles. Autocar says we could see the GLC F-Cell introduced at the Frankfurt Motor Show in the fall of 2017 before it is offered for lease or sale in 2018. At the moment the price is figured to come in around 50,000 pounds ($75,950 US). The price of a conventional GLC in the UK right now is 34,950 pounds ($53,089 US). The Toyota Mirai is on sale in the UK currently with a retail price of 66,000 pounds ($100,254 US).
Mercedes has used its B-Class platform as its hydrogen fuel cell vehicle since 2002. We don't know if the B-Class F-Cell will continue once this new offering arrives, but it's clear that the small hatchback alone wouldn't be the best challenge for rivals like the "larger-sized sedan" on the way from BMW and Audi's performance-minded H-tron efforts. If the GLC is the model in question it would also give Mercedes another differentiator from the pack; only Hyundai offers a crossover in that segment, the Tucson Fuel Cell.
