What to Look for When Buying an SUV
1. Fuel Efficiency & Real-World MPG
Fuel efficiency is arguably the most important factor when searching for the best MPG on an SUV. But it’s not just about the EPA-estimated numbers you see on the window sticker. Real-world MPG can vary significantly based on driving habits, terrain, climate, and vehicle load. Look for SUVs that consistently deliver close to their advertised MPG in independent tests and user reviews. Pay attention to city vs. highway ratings—city driving typically yields lower MPG due to stop-and-go traffic, while highway driving benefits from steady speeds and aerodynamic efficiency. Hybrid and plug-in hybrid SUVs often excel in city conditions due to electric motor assistance, while diesel and turbocharged gasoline engines may perform better on long highway trips.
2. Powertrain Type: Gas, Hybrid, Plug-In Hybrid, or Electric?
The type of powertrain directly impacts fuel economy, performance, and long-term operating costs. In 2026, buyers have more choices than ever:
– Gasoline engines are still common, especially in larger SUVs. Look for turbocharged four-cylinders or efficient V6s with cylinder deactivation.
– Hybrid SUVs combine a gasoline engine with an electric motor and battery, offering improved MPG without needing to plug in. Examples include the Toyota RAV4 Hybrid and Ford Escape Hybrid.
– Plug-in hybrids (PHEVs) offer electric-only driving for short commutes (typically 20–50 miles) and switch to hybrid mode for longer trips. The Toyota RAV4 Prime and Ford Escape PHEV are strong contenders.
– Electric SUVs (EVs) produce zero tailpipe emissions and have the lowest cost per mile. Models like the Tesla Model Y, Hyundai Ioniq 5, and Ford Mustang Mach-E offer impressive range and efficiency.
Your choice depends on your driving patterns, access to charging, and willingness to adapt to new technology.
3. Size & Cargo Needs
SUV size plays a major role in fuel economy. Compact and subcompact SUVs like the Honda CR-V, Mazda CX-5, and Subaru Crosstrek typically offer the best MPG due to lighter weight and smaller engines. Midsize SUVs such as the Toyota Highlander Hybrid or Ford Explorer provide more passenger and cargo space but at the cost of lower efficiency. Full-size SUVs like the Chevrolet Tahoe or Ford Expedition are the least fuel-efficient, though newer models with hybrid systems (like the Toyota Sequoia Hybrid) are closing the gap.
Consider your typical cargo and passenger load. If you rarely carry more than two people, a compact SUV may be overkill. Conversely, if you frequently transport gear, pets, or a full family, a larger SUV might be necessary—just be prepared for lower MPG.
4. Drivetrain: FWD, AWD, or 4WD?
Front-wheel drive (FWD) SUVs are generally more fuel-efficient than all-wheel drive (AWD) or four-wheel drive (4WD) models because they have fewer mechanical components and less weight. However, AWD is valuable in snowy, rainy, or off-road conditions. Many modern SUVs offer selectable or automatic AWD systems that disengage when not needed, improving efficiency. For example, the Subaru Forester and Toyota RAV4 offer AWD with minimal MPG penalty. If you live in a mild climate and don’t need off-road capability, FWD is the smarter choice for fuel economy.
5. Technology & Aerodynamics
Advanced engineering plays a big role in improving SUV efficiency. Look for features like active grille shutters (which close at high speeds to reduce drag), underbody panels for smoother airflow, and low-rolling-resistance tires. Many 2026 models also include start-stop systems that shut off the engine at red lights and restart it when you press the accelerator. Infotainment systems with real-time fuel economy feedback can also help you drive more efficiently.
Additionally, lightweight materials such as high-strength steel, aluminum, and composites reduce overall vehicle weight, which directly improves MPG. Brands like Mazda and Hyundai are leaders in this area.
6. Brand Reputation & Reliability
Not all SUVs are created equal when it comes to long-term reliability and fuel economy consistency. Brands like Toyota, Honda, and Subaru have strong reputations for building durable, efficient vehicles with proven hybrid systems. Toyota’s Hybrid Synergy Drive, for example, has been refined over two decades and is known for its reliability. Hyundai and Kia have made significant strides with their electrified lineups, offering competitive warranties and modern tech. On the other hand, some luxury brands may offer high MPG on paper but come with higher maintenance costs and less predictable real-world efficiency.
Check reliability ratings from sources like J.D. Power, Consumer Reports, and Edmunds to ensure your chosen SUV will deliver consistent performance over time.
7. Warranty & Maintenance Costs
Fuel economy isn’t the only cost to consider—maintenance and repairs can add up. Hybrid and electric SUVs often have longer warranties on their battery systems (e.g., 8–10 years or 100,000 miles), which provides peace of mind. However, battery replacement can be expensive if it fails outside the warranty period. Gasoline engines may require more frequent oil changes and tune-ups, but parts and labor are generally more affordable.
Look for brands that offer complimentary maintenance (like Hyundai and Genesis) or low-cost service plans. Also, consider the availability of certified technicians in your area—especially for EVs and PHEVs, which require specialized training.
8. Resale Value & Depreciation
Some SUVs hold their value better than others, which affects your total cost of ownership. Vehicles with high fuel efficiency, strong reliability, and popular features tend to depreciate slower. For example, the Toyota RAV4 and Honda CR-V consistently rank among the top SUVs for resale value. Electric SUVs can be a mixed bag—while models like the Tesla Model Y retain value well, others may depreciate quickly due to rapid technological advancements.
Use tools like Kelley Blue Book (KBB) or Edmunds to estimate depreciation and compare resale values across models.
Different Types of SUVs for Fuel Efficiency
Common Buying Mistakes to Avoid
❌ Mistake: Focusing Only on EPA Ratings
Why it’s bad: EPA estimates are based on controlled laboratory tests and may not reflect real-world conditions. Many drivers find their actual MPG is 10–20% lower, especially in cold weather or with aggressive driving.
What to do instead: Research real-world MPG from owner forums, review sites, and apps like Fuelly. Look for consistent reports across multiple users.
❌ Mistake: Overlooking Total Cost of Ownership
Why it’s bad: A cheaper SUV with poor fuel economy can cost more over time due to higher fuel, maintenance, and insurance costs.
What to do instead: Use online calculators to compare total 5-year ownership costs, including fuel, insurance, repairs, and depreciation.
❌ Mistake: Ignoring Charging Infrastructure (for EVs/PHEVs)
Why it’s bad: Buying an electric or plug-in hybrid SUV without reliable home or public charging can lead to frustration and range anxiety.
What to do instead: Assess your access to charging. If you can’t charge at home, ensure there are fast chargers near your workplace or frequent destinations.
