Performance and Driving Dynamics
Highway Efficiency and Power Delivery
On the highway, the 2017 Suburban balances its large frame with confident stability and predictable handling. The 6.2L V8 pairs with a smooth six-speed automatic that prioritizes relaxed shifts, making long stretches comfortable for both driver and passengers.
Towing and Payload Capability
With up to 8,300 pounds of towing capacity when properly equipped, the Suburban remains competitive among full-size SUVs for boat or trailer hauling. Payload capacity remains strong across trims, with ample room for camping gear or work equipment without feeling cramped in the third row.
Fuel Economy and Real-World Efficiency
Expected MPG Ranges
EPA-estimated highway figures sit around 20 to 21 MPG for RWD variants, while AWD versions typically land near 20 MPG on the highway and 14 MPG in the city. These numbers reflect the combination of a heavy curb weight and the energy demands of powering all four wheels.
Factors Influencing MPG
Towing, aggressive acceleration, and cold climates can noticeably reduce real-world fuel economy. Drivers who adopt steady throttle inputs and use Eco mode when available often see results closer to the upper end of the estimated ranges.
Interior Comfort and Technology
Seating and Cabin Space
The three-row setup comfortably fits eight adults, with generous headroom and legroom in both the second and third rows. Premium trims such as the Premier add softer materials, quieter cabins, and upgraded infotainment screens that enhance daily drives.
Modern Infotainment and Safety Features
Available features like rear cross-traffic alert, lane-keep assist, and forward collision alert help align the Suburban with contemporary safety expectations. The large touchscreen interface remains responsive, though some users note a slight learning curve compared with smaller smartphone apps.
Ownership Costs and Practical Considerations
Maintenance and Reliability
Regular intervals for oil changes, transmission service, and tire rotations remain typical for large SUVs. Many owners report long-term durability when following the recommended maintenance schedule, though repairs can be costlier than on smaller vehicles.
Fuel and Running Costs
Fill-ups for the Suburban will generally be larger than for compact crossovers, especially when towing or hauling. Planning routes with fuel-efficient roads and using recommended tire pressures can help manage long-term ownership costs.

FAQ
Reader questions
How does the 2017 Suburban compare on MPG with newer models in its class?
The 2017 Suburban’s highway MPG is competitive with other 2016–2018 full-size SUVs, though newer models often introduce mild-hybrid systems that can improve efficiency by a few MPG on average.
Is the 6.2L V8 a good choice for everyday driving around town?
Yes, the V8 provides smooth power for merging and passing, but drivers notice lower city MPG; using Eco mode and gentle throttle inputs can make daily driving more efficient.
Does the AWD system significantly affect highway fuel economy? AWD typically reduces highway MPG by about one to two units compared with RWD due to added drivetrain drag, while delivering better traction in wet or snowy conditions. What real-world MPG can I expect if I tow a mid-size trailer?
Expect highway MPG to drop into the mid-teens or lower when towing a sizable trailer, depending on trailer weight, speed, and road conditions.
