Older Models
Information was a little hard to gather for the years between 2009 and 2016, but I did find 2008 and 2017, which I included in the table below.
| Year | Model | Fuel Tank Capacity |
|---|---|---|
| 2017 | Clarity Fuel Cell | 5.46 kg of hydrogen |
| 2008 | FCX Clarity | 4.1 kg of hydrogen at 5000 psi |
Note: The Clarity has undergone various changes over the years, including different power trains like fuel cell, electric, and plug-in hybrid versions.
The 2008 FCX Clarity’s fuel tank capacity is given in terms of hydrogen weight, and it’s important to note that this model was a hydrogen fuel cell vehicle. The range on a full tank for the 2008 model was EPA certified at 240 miles.
How the Hybrid Compares to the Standard Model
Comparing the fuel efficiency of the Honda Clarity hybrid model to the standard model involves looking at different types of powertrains. The standard model typically refers to the fuel cell version, while the hybrid model is the plug-in hybrid.
The 2021 Plug-in Hybrid has great fuel efficiency, with a MPG on electricity of 110 MPGe and a MPG on gas only of 42 MPG (1).
The 2021 Honda Clarity Fuel Cell version, which represents the standard model, has a fuel economy of 68 MPG.
