How Many MPG Will a Suburban Get Pulling a Trailer?

The Chevrolet Suburban, a powerful and versatile SUV, has established itself as a formidable presence on the road, capturing the hearts of adventure seekers and travel enthusiasts alike. While it boasts an impressive fuel efficiency for it’s size in everyday driving, the burning question for many remains: "How many miles per gallon (MPG) will a Suburban get when pulling a trailer?" This query has surged as more individuals embark on unforgettable journeys, seeking to explore the wonders of the great outdoors. Admittedly, determining the precise MPG for a Suburban towing a trailer can be a complex affair, as numerous factors come into play, such as the trailer's weight, aerodynamic design, driving terrain, and the Suburban's engine power. Nonetheless, factors aside, one can venture to explore the general MPG range for this mighty SUV, attaining a better understanding of what lies ahead on their road to adventure.

Is Suburban Good for Towing?

Suburbans are renowned for their robustness and capability when it comes to towing. These large and muscular SUVs possess exceptional towing capacities, reaching up to an impressive 8,300 pounds.

These vehicles are built on sturdy frames, which enable them to withstand the intense strain that comes with towing heavy loads. This robust construction, complemented by powerful engines and strong drivetrains, ensures that Suburbans can confidently handle the added weight without compromising performance or safety.

From integrated trailer brake controllers to rearview camera systems, these amenities provide drivers with additional control and convenience while maneuvering their towed items.

With remarkable tow ratings, sturdy construction, advanced technologies, and spacious interiors, they excel in handling various towable items.

It’s no surprise that towing a trailer has a significant impact on your vehicle’s gas mileage. With estimates suggesting that every 100 lbs. of additional weight reduces fuel economy by about two percent, the effect of hauling a sizable trailer on your fuel efficiency quickly becomes apparent.

How Much Does Pulling a Trailer Affect Gas Mileage?

When it comes to the impact of pulling a trailer on gas mileage, the numbers certainly add up. Estimates suggest that for every 100 lbs. of additional weight added to a truck, fuel economy can decrease by up to two percent. Considering this, it becomes apparent that towing a substantial trailer can have a significant effect on your vehicles fuel efficiency.

A larger, bulkier trailer will create more resistance against the wind, leading to a more substantial decrease in fuel economy. On the other hand, smaller, more streamlined trailers may have a slightly lesser impact on gas mileage, though it will still be significant nonetheless.

Furthermore, the terrain you drive on can impact gas mileage when towing a trailer. Uphill climbs, for instance, will require the engine to work harder, resulting in increased fuel consumption. Similarly, frequent stops and starts, such as in heavily congested areas or traffic, can further impact gas mileage as the constant acceleration and deceleration demand additional energy from the vehicle.

Smooth, consistent acceleration, maintaining a steady speed, and avoiding sudden braking or accelerating can mitigate some of the impact on gas mileage. In contrast, aggressive driving styles and abrupt changes in speed can further decrease fuel efficiency.

The significant drop in fuel economy resulting from the added weight and aerodynamic resistance is a natural consequence of the strain placed on the vehicle. Therefore, when planning long trips or regular towing, it’s essential to factor in the increased fuel consumption and adjust accordingly.

Tips for Maximizing Fuel Efficiency When Towing a Trailer

  • Keep your tires properly inflated.
  • Choose the right gear for towing.
  • Avoid excessive idling.
  • Avoid aggressive driving and sudden acceleration or braking.
  • Maintain a steady and consistent speed.
  • Reduce the weight being towed by removing unnecessary items.
  • Consider using a trailer with a streamlined design.
  • Use cruise control when appropriate.
  • Plan your route to minimize stops and avoid traffic congestion.
  • Perform regular maintenance on your vehicle and trailer.
  • Consider using a fuel additive to improve fuel efficiency.
