How much gas can a Challenger hold?

The Dodge Challenger typically holds about 18.5 gallons of gasoline in its tank, roughly 70 liters. This is the standard capacity for most modern Challenger trims.


This article explains the official fuel tank capacity of the Challenger, what that means for fueling and potential range, and how it applies across common variants from the V6 to high‑performance HEMI models. Capacity is generally consistent across newer Challengers, though usable fuel and range depend on engine choice and driving conditions.


Official fuel tank capacity across the Challenger lineup


The following reflects the nominal tank size that applies to the vast majority of recent Challenger models. Note that “nominal capacity” refers to the total tank size, not exactly how much fuel you can routinely use on a trip.



  • 18.5 gallons (70 liters) – nominal fuel tank capacity for most modern Dodge Challenger models, including V6 and V8/Hemi variants.


Keep in mind that the actual driving range per tank will vary with engine choice, transmission, tires, and driving style, but the tank size itself remains 18.5 gallons for the contemporary Challenger.


What this means for driving and refueling


With a standard 18.5-gallon tank, Challenger drivers typically experience hundreds of miles of range per tank, depending on how aggressively the car is driven and the engine configuration. The more fuel-efficient V6 versions will tend to push the upper end of that range, while high-performance Hellcat models consume fuel more quickly.


In short, the Challenger’s gas tank is designed to balance performance with practical range, supporting long highway cruises and everyday driving alike.


Summary: The Challenger holds 18.5 gallons of fuel in its tank across most modern models, providing a practical balance between range and performance.

How far can a Dodge Challenger go on a full tank?


A Dodge Challenger can go between 250 and over 400 miles on a full tank, depending on the engine and driving conditions. The exact range varies by trim, with the most fuel-efficient V6 models (like the SXT and GT) achieving up to 30 highway MPG and higher, while the V8 models get lower mileage. All trims have an 18.5-gallon fuel tank. 
Range examples by trim (approximate)

  • Most efficient trims (SXT, GT): With up to 30 MPG on the highway, these models can travel over 550 miles on a full tank, and around 350 miles in the city. 
  • V8 trims (R/T, Scat Pack, SRT Hellcat): These models have lower MPG ratings, resulting in a shorter range. For example, a Scat Pack might get around 15 MPG in the city, giving it a range of about 275 miles, while a Hellcat might get around 13 MPG in the city, for a range of about 240 miles. 
  • Highway driving: On the highway, a Challenger can travel even farther. An SXT model with 30 MPG can go over 550 miles, while a Scat Pack with 23 MPG can travel about 425 miles. 

Factors that affect range
  • Driving conditions: City driving uses more fuel than highway driving. 
  • Engine size: V8 engines require more fuel to operate than V6 engines. 
  • Driving style: Aggressive driving can significantly reduce fuel efficiency. 
  • Vehicle maintenance: A well-maintained vehicle will perform better than one that is not. 



Do challengers use a lot of gas?


On the highway, the new Dodge Challenger clocks in at around 30 mpg. It gets around 19 mpg on city streets.



How many gallons is a Challenger tank?


It takes about 18.5 gallons of gas to fill up a Dodge Challenger, as this is the standard fuel tank capacity for all trim levels. The total cost to fill the tank will vary depending on the current price of gas in your area and which grade of fuel your specific model requires, with performance-oriented trims often needing premium fuel. 

  • Fuel tank size: 18.5 gallons for all models 
  • Fuel type: Varies by trim; many models, especially performance versions, require premium fuel (919191 octane or higher) 
  • Total cost: Depends on the price of gas. For example, in October 2025, with a national average of about $3.21$ 3.21$3.21 per gallon, a full tank would cost approximately $59.40$ 59.40$59.40 (18.518.518.5 gallons x$3.21x $ 3.21𝑥$3.21), but this can fluctuate significantly based on location and price.
