How many miles per gallon does a Chevy Suburban 6.2 get?
The 6.2-liter EcoTec3 V8 in the Suburban offers strong performance, but its fuel economy is modest compared with smaller or more efficient SUVs. In recent model years, 2WD versions typically deliver about 15 mpg in the city and 20 mpg on the highway, while 4WD versions usually show around 14 mpg in the city and 20 mpg on the highway; combined mileage generally lands in the mid-teens. Numbers vary by year, drivetrain, and configuration.
EPA estimates by drivetrain
Representative EPA ranges for the latest Suburban models with the 6.2L V8 are shown below. Always verify the exact window sticker for your specific configuration.
- Rear-wheel drive (2WD): approximately 15 mpg city / 20 mpg highway; combined around 17 mpg.
- Four-wheel drive (4WD): approximately 14 mpg city / 20 mpg highway; combined around 16–17 mpg.
These figures reflect the impact of weight, aerodynamics, and gearing on a vehicle of this size. In practice, highway driving often gets closer to the upper end of the range, while city driving with stops and heavy loads tends to reduce mileage.
Model-year and configuration notes
Fuel economy can shift slightly between generations and option packages due to changes in transmission tuning, axle ratios, or technology. Always check the official EPA rating for the exact trim and year you’re considering.
Real-world factors and tips to maximize MPG
Beyond the official EPA numbers, several practical factors influence real-world fuel economy. The following tips can help you maximize efficiency when piloting a Suburban with the 6.2L V8.
- Limit payload and cargo weight to reduce energy required for acceleration and climbs.
- Maintain proper tire inflation and alignment to minimize rolling resistance.
- Avoid roof racks and other aerodynamic drag sources when not needed.
- Drive smoothly: steady speeds, gradual accelerations, and careful braking improve efficiency.
- Keep up with maintenance, including air filters, spark plugs, and engine oil with the manufacturer-recommended viscosity.
With mindful driving and regular maintenance, you can approach the upper end of the Suburban 6.2’s efficiency range, though it will remain less frugal than many lighter SUVs.
Summary
The Chevy Suburban equipped with the 6.2-liter V8 generally gets about 15 mpg in city driving and 20 mpg on the highway for 2WD models, with around 14 mpg city and 20 mpg highway for 4WD models. Combined mileage typically sits in the mid-teens, subject to year, drivetrain, payload, and driving style. For buyers prioritizing fuel economy, consider lighter configurations or the alternative 5.3-liter engine option, and employ efficiency-focused driving and maintenance habits.
