If you’re considering the Mazda CX-90, chances are you’re looking for a premium SUV that offers luxury, performance, and great fuel economy. The CX-90 is Mazda’s largest and most powerful SUV yet — built for families, long road trips, and American highways.
But how fuel-efficient is it really? Let’s break down the Mazda CX-90 MPG ratings, hybrid options, real-world mileage, and how it compares to competitors like the Toyota Highlander Hybrid and Kia Telluride.
⚙️ Quick Overview: Mazda CX-90 MPG Ratings (EPA Estimated)
Here’s a quick look at the official EPA MPG figures for different Mazda CX-90 models 👇
| Model / Engine Type | Drivetrain | City (MPG) | Highway (MPG) | Combined (MPG) |
|---|---|---|---|---|
| 3.3L Turbo I6 (Base) | AWD | 24 | 28 | 25 |
| 3.3L Turbo I6 (High Output) | AWD | 23 | 28 | 25 |
| Plug-In Hybrid (PHEV) | AWD | 56 MPGe* | 25 (Gas only) | 25 (Gas only) |
🟢 MPGe = Miles Per Gallon Equivalent (when running on electric + gas power).
🌿 CX-90 Hybrid Advantage: Go Farther with Less Gas
Mazda introduced the CX-90 PHEV (Plug-In Hybrid) for drivers who want both power and efficiency. It combines a 2.5-liter 4-cylinder engine with an electric motor for short all-electric drives — perfect for city commutes or errands.
- 🔋 Electric-only range: ~26 miles
- ⛽ Total range (electric + gas): Around 490 miles
- ⚡ Charging time: ~2.5 hours (240V Level 2 charger)
So, if your daily commute is under 25 miles, you might hardly use gas at all!
🧭 Real-World MPG: What Drivers Are Reporting
While EPA numbers are a good starting point, real-world mileage often varies based on driving style, terrain, and weather.
| Driving Condition | Average MPG (Turbo Model) | Average MPG (PHEV) |
|---|---|---|
| City (stop & go traffic) | 21–23 | 55+ MPGe (electric mix) |
| Highway (steady 65 mph) | 28–30 | 27–29 |
| Mixed / Suburban Driving | 25–26 | 40–45 MPGe |
💡 Tip: Use Mazda’s “Mi-Drive” mode selector to switch between Normal, Sport, and EV modes for optimal fuel use.
🔍 How the CX-90 Stacks Up Against Competitors
If you’re cross-shopping SUVs, here’s how the CX-90 compares to some popular models in terms of fuel economy:
| SUV Model | Engine Type | Combined MPG | Base Price (USD) |
|---|---|---|---|
| Mazda CX-90 Turbo | 3.3L I6 | 25 | $39,595 |
| Mazda CX-90 PHEV | 2.5L Hybrid | 56 MPGe / 25 Gas | $47,445 |
| Toyota Highlander Hybrid | 2.5L Hybrid | 36 | $42,115 |
| Kia Telluride | 3.8L V6 | 23 | $36,190 |
| Honda Pilot | 3.5L V6 | 22 | $37,090 |
🧠 Verdict: The CX-90 PHEV leads in electric efficiency, while the standard CX-90 Turbo competes well against non-hybrid SUVs in its class.
🛣️ Fuel Economy vs. Performance: Can You Have Both?
Absolutely ✅. The Mazda CX-90’s Skyactiv-G 3.3L Turbo engine offers up to 340 horsepower (with premium fuel) — more than most rivals — yet still delivers 25 MPG combined.
Mazda achieves this with:
- 🧩 48V mild-hybrid system for better start-stop efficiency
- ⚙️ Inline-six layout for smoother torque
- 🪶 Lightweight construction for better aerodynamics
That means you get luxury SUV performance without luxury SUV fuel costs.
⛽ Fuel Type & Recommended Gas
Mazda recommends premium unleaded (91 octane) for maximum power output, though regular 87 octane works fine if you don’t need full performance.
| Fuel Type | Recommended? | Effect on MPG | Effect on Power |
|---|---|---|---|
| Regular (87) | ✅ Acceptable | No major change | Slight drop |
| Premium (91+) | ⭐ Recommended | Optimal efficiency | Full performance |
💬 If you tow or drive in hot conditions, premium gas ensures smoother operation.

✅ Standard Turbo Models: ~25 MPG combined
