The 2021 Ram 2500 with the 6.4L HEMI V8 engine has an estimated fuel economy of 13 miles per gallon (mpg) in the city, 18 mpg on the highway, and 15 mpg combined, according to the U.S. Department of Energy. However, the actual fuel economy can vary depending on factors such as driving habits, weather conditions, terrain, and payload. It’s always advisable to refer to the vehicle’s owner’s manual for specific fuel economy information and to use the onboard fuel economy display to monitor fuel consumption.
Understanding the 6.4 Hemi MPG Engine
As a proud owner of a 2021 Ram 2500 6.4 HEMI, I know firsthand the power and capability that comes with this engine. But what exactly is a 6.4 Hemi MPG engine, and how does it affect fuel efficiency?
Overview of the Engine and its specs
The 6.4 Hemi MPG engine is a V8 engine that is designed to deliver high performance and power. It has a displacement of 6.4 liters, hence the name, and can produce up to 410 horsepower and 429 lb-ft of torque. This engine is paired with an eight-speed automatic transmission that provides smooth and efficient shifts.
How the Engine Affects Fuel Efficiency
While the 6.4 Hemi MPG engine is powerful, it can also consume more fuel compared to smaller engines. However, the 2021 Ram 2500 6.4 Hemi MPG has a range of fuel-saving features that help to optimize fuel efficiency.
One of the key features is the Multi-Displacement System (MDS), which can deactivate four of the eight cylinders when they are not needed. This feature allows the engine to conserve fuel and improve efficiency without compromising performance.
Additionally, the 2021 Ram 2500 6.4 Hemi MPG also has an active grille shutter system that can close the grille when the engine doesn’t need as much airflow. This reduces drag and improves aerodynamics, which can also help to save fuel.
Overall, while the 6.4 Hemi MPG engine may consume more fuel than smaller engines, the fuel-saving features in the 2021 Ram 2500 help to improve fuel efficiency without sacrificing performance.
Tips for Improving MPG
As a 2021 Ram 2500 6.4 Hemi MPG owner, you may be wondering how to improve the fuel efficiency of your truck. Here are some tips and strategies to help you maximize your miles per gallon:
Proper Maintenance and Regular Tune-Ups
Regular maintenance and tune-ups are crucial for keeping your Ram 2500 6.4 Hemi MPG in top condition and maximizing its fuel efficiency.
Some key maintenance tasks to consider include:
- Changing the oil and oil filter on a regular basis
- Replacing air filters as needed
- Checking and maintaining proper tire pressure
- Inspecting and replacing worn spark plugs and wires
- Regularly checking for any fluid leaks or engine issues
By keeping up with these maintenance tasks, you can ensure that your truck is running efficiently and getting the most out of each tank of gas.
Adjusting Driving Habits and Reducing Idling Time
Another way to improve your MPG is to adjust your driving habits and reduce idling time.
Some tips to consider include:
- Avoiding hard acceleration and sudden stops
- Maintaining a consistent speed while driving
- Coasting to a stop instead of braking at the last minute
- Turning off the engine instead of idling for long periods of time
By making these adjustments, you can reduce the amount of fuel your truck consumes and improve its overall efficiency.
Using High-Quality Fuel and Keeping Tires Properly Inflated
Finally, using high-quality fuel and keeping your tires properly inflated can also help to improve your MPG. Consider using a higher octane fuel for better performance and efficiency.
Additionally, keeping your tires inflated to the recommended pressure can reduce rolling resistance and improve fuel efficiency.
By following these tips and strategies, you can improve the fuel efficiency of your 2021 Ram 2500 6.4 Hemi MPG and get the most out of each tank of gas.
Aftermarket Options for Improved MPG
If you’re looking to improve the fuel efficiency of your 2021 Ram 2500 6.4 Hemi MPG beyond what can be achieved through regular maintenance and driving habits, there are aftermarket options available that can help. Here are two options to consider:
Upgrading Air Intake and Exhaust Systems
Upgrading your truck’s air intake and exhaust systems can improve its performance and efficiency. By increasing the amount of air that flows into the engine and reducing exhaust restrictions, you can improve combustion and increase power while also improving fuel efficiency.
Aftermarket air intake systems typically replace the stock air filter and air intake tube with higher-flowing components that allow more air to reach the engine. Exhaust system upgrades can include replacing the muffler or adding a larger diameter exhaust pipe to reduce restrictions and improve exhaust flow.
Adding Performance Chips or Programmers
Performance chips or programmers are electronic devices that can be installed in your truck’s engine control module (ECM) to optimize performance and efficiency.
These devices can adjust factors such as fuel injection timing and air/fuel ratios to improve combustion and increase power while also improving fuel efficiency.
Some performance chips and programmers are specifically designed for improving fuel efficiency, while others focus more on increasing power and performance. When choosing a chip or programmer,
Be sure to look for one that is compatible with your truck’s make and model and that has good reviews and a proven track record of success.
By upgrading your air intake and exhaust systems or adding a performance chip or programmer, you can improve the fuel efficiency of your 2021 Ram 2500 6.4 Hemi MPG beyond what can be achieved through regular maintenance and driving habits.
