The Chevy HHR, a retro-styled station wagon introduced by Chevrolet in 2005 for the 2006 sales year, has always stood out for its unique design and practicality.
Throughout its entire short life, the Chevy HHR came with a gas tank size of 16 gallons (60.6 liters), catering to both city commuters and long-distance travelers.
Down below I’ve compiled some detailed comparison tables for the different models during it’s half decade of production. I’ve also added some info about fuel efficiency and range.
Gas Tank Capacity by Model Year
For the Chevy HHR, variations in gas tank size are minimal across its production years. However, understanding these specifics can be crucial for owners looking to maximize their vehicle’s performance and efficiency.
- 2006-2011: Across all model variations, including the LS, LT, and SS models, the Chevy HHR maintained a consistent gas tank size of 16 gallons. This consistency reflects Chevrolet’s commitment to providing a reliable and efficient vehicle suited for various driving needs.

Fuel Efficiency and Range

On average, the HHR achieves about 22 miles per gallon (mpg) in the city and 30 mpg on the highway.
The SS model, with its turbocharged engine, sees a slight decrease in efficiency due to its increased power output.
Impact on Driving and Planning
The 16-gallon tank capacity, combined with the HHR’s fuel efficiency, translates to:
- 320 miles in the city
- 480 miles on the highway
This range capability allows for less frequent fuel stops and provides a level of freedom for road trips and daily commutes alike. Owners should consider their driving habits and fuel prices when planning long trips, as these factors can significantly affect overall travel costs and planning.
