What is the gas mileage on a 2005 Ford Excursion XLS 6.8 L V10 SUV?
Typically, the 2005 Excursion XLS with a 6.8-liter V10 averages about 12 mpg in city driving and around 16–17 mpg on highways, with a combined figure near 13–15 mpg depending on drivetrain and load. Real-world results vary widely based on drivetrain, cargo, terrain, and driving style.
Vehicle context: the Excursion and its 6.8 L V10
The 2005 Ford Excursion XLS sits on a heavy-duty chassis and uses a gas-powered 6.8-liter V10 engine. This powertrain delivers strong low-end torque for towing and heavy payloads, but the trade-off is fuel economy that lags behind smaller, lighter SUVs. Expect a substantial weight to impact fuel efficiency, with performance tuned more toward capability than efficiency.
EPA fuel economy estimates
The following figures summarize approximate EPA estimates published for the 2005 Excursion V10. They depend on whether the model is two-wheel drive (2WD) or four-wheel drive (4WD) and may vary slightly by production year and configuration.
- Two-wheel drive (2WD) with a 6.8 L V10: roughly 12 mpg city / 17 mpg highway; combined around 14–15 mpg.
- Four-wheel drive (4WD) with a 6.8 L V10: roughly 11 mpg city / 16 mpg highway; combined around 13 mpg.
These figures reflect the era’s expectations for a large, heavy SUV with a big V10 engine. Real-world mileage often falls a bit short of these numbers, especially when towing or carrying a full passenger/load.
Real-world factors that affect mpg
Several practical factors influence actual fuel economy for the Excursion in daily use. The following list highlights the main variables owners report as affecting mpg most noticeably.
- Weight and payload: carrying people, cargo, and towing gear reduces efficiency.
- Drivetrain and tires: 4WD configurations and low-profile or underinflated tires lower mileage.
- Driving conditions: city driving with frequent stops and hills lowers mpg versus steady highway cruising.
- Maintenance and components: air filters, spark plugs, oxygen sensors, and exhaust condition can impact efficiency.
- Aerodynamics and accessories: roof racks, spoilers, and added accessories increase air resistance.
- Fuel quality and octane: using the recommended fuel and maintaining fueling habits can influence performance and economy.
In practical terms, many owners report real-world numbers that hover around the EPA estimates, often slipping into the low teens in city use and mid-teens on highway journeys, with even lower figures under heavy load or challenging terrain.
Tips to optimize mpg on a classic V10 Excursion
While you’re working with a vintage, heavy-duty SUV, several strategies can help squeeze a few more miles per gallon whenever possible.
- Lighten the load: remove unnecessary cargo and roof racks when not in use.
- Maintain proper tire pressures and alignment to reduce rolling resistance.
- Drive smoothly: gradual acceleration, steady speeds, and mindful braking help conserve fuel.
- Schedule regular maintenance: keep the air filter, spark plugs, and oxygen sensors in good condition.
- Use the appropriate fuel: follow the manufacturer’s recommended gasoline for your engine.
Keep expectations aligned with the Excursion’s design: this vehicle prioritizes towing and passenger capacity over urban fuel economy, so plan fuel costs accordingly.
Summary
The 2005 Ford Excursion XLS with the 6.8 L V10 typically delivers around 12 mpg in city driving and 16–17 mpg on highways, with a combined figure near 13–15 mpg. Real-world results vary with drivetrain (2WD vs 4WD), payload, driving conditions, and maintenance. For buyers or current owners, understanding these factors helps set realistic expectations and budgeting for fuel costs, while practical driving and maintenance habits can help maximize efficiency where possible.
