Honda Accord Fuel Tank Capacity & Fuel Efficiency

Honda Accord: Fuel Tank Capacity, Fuel Efficiency, and KM/L Across Generations

The Honda Accord has been a popular midsize sedan for decades, known for its reliability, comfort, and fuel efficiency. In this comprehensive guide, we’ll explore the fuel tank capacity, fuel efficiency, and kilometers per liter (KM/L) across various generations and variants of the Honda Accord.

Understanding Fuel Efficiency Metrics

Before diving into the specifics of the Honda Accord, it’s important to understand the different metrics used to measure fuel efficiency:

• Fuel tank capacity: The total volume of fuel a vehicle’s tank can hold, typically measured in liters or gallons.
• Fuel efficiency: Often expressed in miles per gallon (MPG) or liters per 100 kilometers (L/100km).
• KM/L: Kilometers per liter, another measure of fuel efficiency commonly used in some countries.

Honda Accord Generations Overview

The Honda Accord has gone through multiple generations since its introduction in 1976. We’ll focus on the more recent generations, as they are most relevant to current and prospective owners.

Tenth Generation (2018-2023)

The tenth generation Accord saw significant improvements in fuel efficiency, particularly with the introduction of hybrid variants.

• Fuel tank capacity: 14.8 gallons (56 liters) for gasoline models, 12.8 gallons (48.5 liters) for hybrid models
• Fuel efficiency (2022 model):
  • LX and EX-L trims: 30 city / 38 highway / 33 combined MPG
  • Sport 1.5T and Special Edition: 29 city / 35 highway / 32 combined MPG
  • Sport 2.0T and Touring 2.0T: 22 city / 32 highway / 26 combined MPG
  • Hybrid and Hybrid EX-L: 48 city / 47 highway / 47 combined MPG
  • Hybrid Sport and Touring: 44 city / 41 highway / 43 combined MPG

Ninth Generation (2013-2017)

The ninth generation Accord introduced more efficient engine options and improved aerodynamics.

• Fuel tank capacity: Approximately 17.2 gallons (65 liters)
• Fuel efficiency (2015 model):
  • 2.4L 4-cylinder: 27 city / 36 highway / 31 combined MPG
  • 3.5L V6: 21 city / 34 highway / 26 combined MPG

Eighth Generation (2008-2012)

This generation saw an increase in size but maintained competitive fuel efficiency.

• Fuel tank capacity: Approximately 18.5 gallons (70 liters)
• Fuel efficiency (2011 model):
  • 2.4L 4-cylinder: 23 city / 34 highway MPG
  • 3.5L V6: 20 city / 30 highway MPG

Fuel Efficiency Comparison Across Generations

To better understand how the Honda Accord’s fuel efficiency has improved over time, let’s compare the average combined MPG for base models across generations:

This comparison demonstrates the steady improvement in fuel efficiency over time, with the latest generation offering significantly better fuel economy than its predecessors.

Factors Affecting Fuel Efficiency

Several factors can impact the real-world fuel efficiency of a Honda Accord:

• Driving conditions: City driving typically results in lower fuel efficiency compared to highway driving.
• Maintenance: Regular maintenance, including oil changes and tire pressure checks, can help maintain optimal fuel efficiency.
• Driving habits: Aggressive acceleration and braking can significantly reduce fuel efficiency.
• Climate: Extreme temperatures can affect fuel consumption, particularly when using air conditioning or heating extensively.

Maximizing Fuel Efficiency in Your Honda Accord

To get the most out of your Honda Accord’s fuel efficiency, consider the following tips:

1. Use the Eco Assist System, which provides real-time feedback on your driving efficiency.
2. Maintain proper tire pressure to reduce rolling resistance.
3. Use the recommended grade of motor oil.
4. Remove unnecessary weight from the vehicle.
5. Plan your trips to combine multiple errands and avoid peak traffic times.

Honda Accord Hybrid: A Fuel Efficiency Champion

The Honda Accord Hybrid deserves special mention for its exceptional fuel efficiency. Introduced in the ninth generation and refined in the tenth, the hybrid variant offers significant fuel savings without compromising performance.

Key Features of the Accord Hybrid:

• Two-motor hybrid system
• Regenerative braking to recapture energy
• Smaller fuel tank (12.8 gallons) compared to non-hybrid models
• Impressive fuel economy ratings, often exceeding 45 MPG combined

Real-World Fuel Efficiency Data

While manufacturer-provided fuel efficiency figures are useful, real-world data can provide a more accurate picture of what owners can expect. According to user-reported data from Fuelly:

• 2022 Honda Accord: 34.8 Avg MPG (based on 113 vehicles and 6,351 fuel-ups)
• 2021 Honda Accord: 36.9 Avg MPG (based on 124 vehicles and 7,265 fuel-ups)
• 2020 Honda Accord: 35.7 Avg MPG (based on 280 vehicles and 16,163 fuel-ups)

These figures suggest that real-world fuel efficiency can be slightly lower than EPA estimates but still impressive for a midsize sedan.

Comparing Honda Accord Fuel Efficiency to Competitors

To put the Honda Accord’s fuel efficiency into perspective, let’s compare it with some of its main competitors in the midsize sedan segment (2022 models, base trims):

This comparison shows that the Honda Accord remains competitive in terms of fuel efficiency within its class.

The Future of Fuel Efficiency in Honda Accords

As automotive technology continues to advance, we can expect future generations of the Honda Accord to offer even better fuel efficiency. Some potential developments include:

• Improved hybrid systems with greater electric-only range
• Possible introduction of plug-in hybrid variants
• Further refinements to gasoline engine efficiency
• Lightweight materials to reduce overall vehicle weight
• Advanced aerodynamics to reduce drag

The Honda Accord has consistently demonstrated impressive fuel efficiency across its various generations and variants. From its early days to the latest hybrid models, Honda has continually improved the Accord’s fuel economy while maintaining the performance and comfort that have made it a popular choice among midsize sedan buyers.
