How many miles can an RDX go?
In practical terms, most current Acura RDX models can travel roughly 350 to 400 miles on a full tank, depending on year, drivetrain, and driving conditions.
Understanding the RDX’s fuel range
The figures below draw on EPA fuel-economy estimates and the typical fuel-tank capacity for recent RDX models with the 2.0-liter turbo engine. They provide a useful baseline for planning road trips or daily commutes.
Fuel-tank capacity, engine and drivetrain, and EPA efficiency together determine range. The RDX’s tank is about 15.9 gallons, and real-world range varies with how you drive, where you drive, and how aggressively you accelerate or brake.
- Fuel-tank capacity: 15.9 gallons
- Estimated combined fuel economy: roughly 22–25 miles per gallon, depending on drivetrain (FWD vs. AWD) and model year
- Estimated range on a full tank: about 350–400 miles
- Note: Real-world range will vary from the EPA estimates based on driving conditions and habits
In practice, highway cruising tends to yield the upper end of the range, while city and stop-and-go driving typically produce numbers toward the lower end. With sensible driving, most owners should expect the mid- to upper 300s miles per tank under typical mixed conditions.
What factors influence the RDX’s range?
Several variables can push the actual mileage per tank above or below the baseline estimates. The following factors commonly play a role:
- Driving style: smooth acceleration and highway cruising improve efficiency; rapid acceleration and heavy braking reduce it
- Terrain and traffic: flat, open highways boost mpg; hills, stop-and-go traffic and idling lower it
- Climate and climate-control use: extreme temperatures and continuous A/C or cabin heating affect fuel use
- Tire condition and inflation: underinflated tires increase rolling resistance and reduce efficiency
- Cargo load and vehicle weight: heavier loads decrease mpg
Understanding these factors helps explain why some trips may approach the higher end of the range while others land closer to the lower end.
Model-year variations
Current generation (roughly 2023–2024)
For the latest generation with the 2.0-liter turbo engine and 10-speed automatic, range estimates align with the figures above: a 15.9-gallon tank and a combined mpg in the low 20s to mid-20s, yielding about 350–400 miles per tank under typical mixed driving.
Earlier years and variants
Earlier model years and any hybrid or special variants can shift the numbers slightly due to different powertrains or tuning. Always check the specific EPA ratings and your vehicle’s user manual for precise figures.
Summary
For most current Acura RDX models, expect roughly 350–400 miles per full tank, with real-world results swaying based on drivetrain, driving conditions, and habits. This range provides a practical benchmark for planning trips and budgeting fuel, while reminding drivers to consider personal factors that influence efficiency.
