Dodge Durango V6 vs. V8: Fuel Economy, Towing Feel, and Sound

Choosing between the Dodge Durango's 3.6L V-6 and 5.7L V-8 engines often comes down to balancing fuel economy with the feel and sound of a more powerful engine, especially when considering towing needs. While both offer a robust SUV experience, their distinct characteristics cater to different driving priorities.

Understanding the Engines

The Dodge Durango offers two primary engine choices that significantly impact its performance and efficiency: the 3.6L V-6 and the 5.7L V-8. The 3.6L V-6 engine is known for its balanced performance, offering a good blend of power for daily driving and reasonable fuel economy. It's a popular choice for families and those who prioritize efficiency without sacrificing capability.

On the other hand, the 5.7L V-8 engine provides a more commanding presence, with increased horsepower and a distinctive V-8 rumble. This engine is often favored by drivers who appreciate a more aggressive acceleration, a robust towing feel, and the classic sound of a V-8. While it offers more power, it naturally comes with a lower fuel economy.

Fuel Economy and Cost

When comparing the 3.6L V-6 and the 5.7L V-8, fuel efficiency is a significant factor. The V-6 engine generally offers better mileage, which can translate to lower annual fuel costs. For example, a used 2024 Dodge Durango GT Plus with the 3.6L V-6 engine is estimated at 18/25 mpg and an EPA estimated annual fuel cost of $3,200. In contrast, a new 2026 Dodge Durango GT HEMI V8, equipped with the 5.7L V-8, is rated at 14/21 mpg, with an EPA estimated annual fuel cost of $4,750.

This difference in fuel economy can add up over time, making the V-6 an attractive option for those who drive frequently or are conscious of their fuel budget. However, the V-8's power often justifies the increased fuel expense for drivers who value performance.

Towing Feel and Sound

The experience of towing with a Durango differs notably between the V-6 and V-8 engines. While both are capable, the 5.7L V-8, with its greater horsepower, tends to provide a more effortless and confident towing feel, especially with heavier loads. The added torque from the V-8 can make merging onto highways or climbing grades with a trailer feel more secure and less strained.

Beyond just power, the sound of the engine is a key differentiator. The 5.7L V-8, often referred to as a HEMI V8, delivers a distinct, throaty exhaust note that many enthusiasts find appealing. This powerful sound contributes to the overall driving experience, especially when accelerating or under load. The 3.6L V-6, while smooth and capable, offers a more subdued engine sound.

Which One for You?

Deciding between the V-6 and V-8 Durango ultimately depends on your priorities. If fuel economy and a balanced daily driver are at the top of your list, the 3.6L V-6 is an excellent choice. It provides ample power for most situations and keeps fuel costs in check. However, if you frequently tow, desire a more potent acceleration, or simply love the distinctive sound and feel of a V-8 engine, the 5.7L V-8 will likely be more satisfying. It delivers that classic muscle SUV experience that many drivers crave.
