It's not like your average fuel-cell car, which could be a huge boon to consumers as the infrastructure continues to expand.
After its initial preview in 2016, the GLC F-Cell will finally receive a proper debut at the Frankfurt Motor Show.
It's still in pre-production, but it carries an important piece of tech you won't find on other hydrogen cars.
Along with receiving electricity from the fuel cell, the GLC F-Cell can be charged like a plug-in hybrid using an EV charger.
In 2016, it was reported to pack a 9-kWh battery.
A full battery could produce a range of between 31 and 35 miles.
In conjunction with a full tank of hydrogen, the GLC F-Cell's full range is closer to 300 miles.
This would be a big benefit to owners who aren't close to every hydrogen station on the planet.
Given how little hydrogen infrastructure exists in the US, I wouldn't see this car anywhere but California for several years still.
We'll get to see it without all the camouflage in Frankfurt next week.
This is only one part of Mercedes-Benz's quest to electrify more of its cars.
