How many miles per gallon does a Sprinter motorhome get?

Most Sprinter-based motorhomes achieve roughly 15–20 miles per gallon on highway driving, with real-world results often in the teens to low 20s depending on the chassis engine, payload, and driving conditions.


Sprinter motorhomes—vehicles built on the Mercedes-Benz Sprinter van chassis—vary widely in fuel economy. The exact miles per gallon depends on engine choice, weight from amenities, and how the vehicle is used. This article breaks down typical ranges, factors that influence efficiency, and practical tips to maximize mileage.


What affects fuel efficiency in Sprinter motorhomes


Several variables determine mpg for Sprinter motorhomes, and the numbers can swing substantially from one setup to another.



  • Engine type: diesel (3.0L V6 Turbo Diesel) versus gasoline (2.0L I4 Turbo) options; diesel engines typically deliver better highway efficiency and torque for loaded RVs.

  • Payload and weight: extra water, fuel, and living amenities add mass, reducing mpg.

  • Aerodynamics and height: roof racks, awnings, and added clearance increase drag, lowering efficiency.

  • Driving conditions and habits: steady highway speeds around 60–65 mph are often most efficient; city driving and hills reduce mpg.

  • Tire choice and maintenance: properly inflated, low-rolling-resistance tires help; poor alignment or wear hurts numbers.


Understanding these factors helps set realistic expectations for fuel economy on trips and informs purchasing and driving decisions.


Typical mpg ranges by engine type


Engine choice largely determines mpg, though actual results vary with payload and usage. The following ranges reflect common owner-reported figures for Sprinter-based RVs, noting that conversions add weight and alter aerodynamics.



  • Diesel Sprinter (3.0L V6 Turbo Diesel): Real-world mpg commonly sits in the mid-teens to low-20s combined; highway figures can reach the upper end of this range under lighter loads, while full hookups and heavier payloads pull numbers down.

  • Gasoline Sprinter (2.0L I4 Turbo or similar): Real-world mpg tends to be lower, often in the mid-teens to low-20s combined; city driving and heavier payloads can drop mpg further.


In practice, diesel-powered Sprinter motorhomes generally offer better fuel economy on long highway trips, but every build is unique and individual results will vary.


Tips to maximize mileage on Sprinter motorhomes


Smart driving and careful planning can help you squeeze more miles from each gallon.



  • Weight management: limit unnecessary cargo, and monitor water tanks and supplies.

  • Maintain tires and drivetrain: keep tire pressure at recommended levels, ensure proper alignment, and perform regular engine maintenance.

  • Drive efficiently: cruise at a steady speed, use eco-driving techniques, and minimize rapid accelerations.

  • Plan routes to minimize hills and stop-and-go segments; choose highway segments where feasible.

  • Optimize aerodynamics: remove nonessential roof items when not in use; consider wind deflectors or other aero improvements if available for your model.


Applying these practices can help improve fuel economy on longer journeys and make trips more cost-effective.


Summary


Across Sprinter-based motorhomes, a realistic expectation is roughly 15–20 mpg on highway driving, with diesel configurations generally offering better highway efficiency than gasoline ones. Because each conversion is different, actual results vary widely based on weight, aerodynamics, driving style, and terrain. Prospective buyers and owners should plan for a broad range and tailor expectations to their specific rig and travel plans.
