This guide will help you cut through the noise and focus on what truly matters: maximizing fuel economy while maintaining the utility, comfort, and reliability you expect from an SUV.
What to Look for When Buying Buying Guide
1. Fuel Economy Ratings (MPG & MPGe)
Fuel economy is the cornerstone of any fuel-efficient SUV purchase. The Environmental Protection Agency (EPA) provides standardized ratings for city, highway, and combined MPG for gasoline vehicles, while electric and plug-in hybrid models are rated in MPGe (miles per gallon equivalent), which measures energy consumption relative to gasoline. When comparing models, always look at the combined MPG or MPGe, as it reflects real-world driving conditions more accurately than city or highway numbers alone. For example, a vehicle rated at 40 MPG combined will save you significantly more fuel over time than one rated at 35 MPG, especially if you drive long distances regularly.
It’s also important to understand that EPA ratings are based on laboratory tests and may not always reflect real-world performance. Factors like driving habits, weather, terrain, and vehicle load can affect actual fuel economy. To get a more accurate picture, consult independent sources like Consumer Reports or Edmunds, which conduct real-world fuel economy tests. Additionally, consider whether the SUV offers different driving modes (e.g., Eco, Sport, EV) that can help optimize efficiency based on your needs.
2. Powertrain Type: Gas, Hybrid, Plug-In Hybrid, or Electric
The type of powertrain significantly impacts fuel economy and overall ownership experience. Traditional internal combustion engine (ICE) SUVs are still common, but their efficiency varies widely depending on engine size, transmission, and vehicle weight. Smaller turbocharged engines often deliver better MPG than larger naturally aspirated ones, but may sacrifice towing capacity and responsiveness.
Hybrid SUVs, such as the Toyota RAV4 Hybrid or Honda CR-V Hybrid, combine a gasoline engine with an electric motor to improve fuel economy without requiring plug-in charging. These models typically achieve 35–40 MPG combined and are ideal for drivers who want better efficiency without the range anxiety of electric vehicles.
Plug-in hybrids (PHEVs) like the Ford Escape PHEV or Toyota RAV4 Prime offer even greater efficiency by allowing you to drive on electric power for 30–50 miles before switching to hybrid mode. This makes them excellent for short commutes while still providing the flexibility of a gasoline engine for longer trips.
Fully electric SUVs (BEVs), such as the Tesla Model Y, Hyundai Ioniq 5, or Ford Mustang Mach-E, produce zero tailpipe emissions and offer the lowest “fuel” costs per mile when charged at home. While they don’t have MPG in the traditional sense, their MPGe ratings often exceed 100, making them the most efficient option. However, they require access to charging infrastructure and may have higher upfront costs.
3. Vehicle Size and Class
SUV size directly affects fuel economy. Generally, smaller SUVs are more efficient than larger ones due to reduced weight and aerodynamic drag. Compact crossovers like the Mazda CX-5 or Subaru Crosstrek typically achieve higher MPG than midsize or full-size SUVs like the Ford Explorer or Chevrolet Tahoe. However, larger SUVs offer more passenger and cargo space, making them better suited for families or those who frequently haul gear.
When choosing a size, consider your typical passenger and cargo needs. If you only occasionally need extra space, a compact or subcompact SUV may be more efficient and cost-effective. For larger families or frequent road trips, a midsize hybrid SUV like the Toyota Highlander Hybrid or Kia Sorento Hybrid offers a good balance of space and efficiency. Full-size SUVs are rarely fuel-efficient, but some, like the Ford Expedition Hybrid (if available), are improving with hybrid technology.
Also, consider the difference between unibody (car-based) and body-on-frame (truck-based) SUVs. Unibody SUVs are generally lighter and more fuel-efficient, while body-on-frame models prioritize off-road capability and towing but consume more fuel.
4. Drivetrain: Front-Wheel Drive vs. All-Wheel Drive
The drivetrain configuration plays a significant role in fuel economy. Front-wheel drive (FWD) SUVs are typically more efficient than all-wheel drive (AWD) models because they have fewer moving parts and less mechanical resistance. For example, a FWD Honda CR-V may achieve 30 MPG combined, while its AWD counterpart might drop to 27 MPG.
However, AWD provides better traction in snow, rain, or off-road conditions, making it a worthwhile trade-off for drivers in colder climates or those who frequently drive on unpaved roads. Many modern SUVs offer intelligent AWD systems that disengage the rear wheels when not needed, helping to minimize fuel economy penalties. If you live in a mild climate and rarely drive in adverse conditions, FWD is usually the more efficient choice.
Some hybrids and electric SUVs use dual-motor setups to provide AWD without a traditional mechanical connection, which can be more efficient than conventional AWD systems. For instance, the Tesla Model Y Dual Motor achieves excellent range despite having AWD capability.
5. Technology and Aerodynamics
Advanced technology and aerodynamic design are key contributors to fuel efficiency. Features like active grille shutters, underbody panels, and streamlined body shapes reduce drag, allowing the engine to work less to maintain speed. SUVs with these features often see a 2–5% improvement in highway MPG.
Additionally, modern infotainment and driver-assist systems can indirectly improve fuel economy. For example, adaptive cruise control and navigation systems with real-time traffic data can help you maintain a steady speed and avoid unnecessary braking and acceleration, which wastes fuel. Some SUVs also include eco-coaching features that provide feedback on your driving habits to help you drive more efficiently.
Look for SUVs with regenerative braking (in hybrids and EVs), which captures energy during deceleration and stores it in the battery, improving overall efficiency. Also, consider models with start-stop technology, which shuts off the engine at stoplights and restarts it when you press the accelerator, saving fuel in city driving.
6. Brand Reputation and Reliability
Not all fuel-efficient SUVs are created equal when it comes to long-term reliability and ownership satisfaction. Brands like Toyota, Honda, and Hyundai have consistently ranked high in reliability studies and offer strong track records for hybrid and electric vehicles. Toyota, for example, has been a pioneer in hybrid technology with its Hybrid Synergy Drive system, used in models like the Prius, RAV4 Hybrid, and Highlander Hybrid.
Reliability matters because a fuel-efficient SUV that requires frequent repairs or has high maintenance costs can negate any savings from better MPG. Check sources like J.D. Power, Consumer Reports, and RepairPal for reliability ratings and common issues. Also, consider the availability of service centers and the cost of parts in your area.
Newer brands like Rivian or Lucid may offer cutting-edge electric SUVs with impressive efficiency, but they often have limited service networks and higher repair costs. If long-term ownership and resale value are priorities, stick with established brands that have proven their durability over time.
7. Warranty and Maintenance Costs
Fuel economy isn’t the only cost to consider—maintenance and warranty coverage play a big role in total cost of ownership. Hybrid and electric SUVs often have longer warranties on their battery systems. For example, Hyundai and Kia offer 10-year/100,000-mile battery warranties, while Toyota provides 8-year/100,000-mile coverage on hybrid components.
Electric SUVs generally have lower maintenance costs because they have fewer moving parts—no oil changes, no spark plugs, and less wear on brakes due to regenerative braking. However, battery replacement can be expensive if it fails outside the warranty period. Hybrids fall somewhere in between, requiring regular maintenance like gas vehicles but with added complexity from the electric motor and battery.
When comparing models, look at the manufacturer’s warranty, included maintenance programs (e.g., Toyota Care), and estimated annual maintenance costs. Some brands also offer complimentary charging or roadside assistance for electric vehicles, which can add value.
8. Resale Value and Depreciation
Fuel-efficient SUVs often hold their value better than less efficient models, especially as gas prices rise and environmental regulations tighten. Hybrids and electric vehicles from reputable brands tend to have strong resale value due to their lower operating costs and growing demand.
For example, the Toyota RAV4 Hybrid and Honda CR-V Hybrid consistently rank among the top SUVs for resale value, according to Kelley Blue Book. Electric SUVs like the Tesla Model Y also retain value well, though depreciation can vary based on battery health and software updates.
When shopping, consider how long you plan to keep the vehicle. If you’re likely to sell or trade in within 3–5 years, prioritize models with strong resale value. Use tools like Edmunds True Cost to Own or KBB 5-Year Cost to Own to compare long-term expenses, including depreciation, fuel, insurance, and maintenance.
Different Types of Buying Guide
Common Buying Mistakes to Avoid
❌ Mistake: Focusing Only on EPA Ratings
Why it’s bad: EPA fuel economy ratings are based on controlled tests and may not reflect real-world driving conditions. Aggressive driving, cold weather, or frequent short trips can reduce actual MPG by 10–30%.
What to do instead: Look at real-world test results from independent reviewers and consider your typical driving patterns. Use tools like Fuelly to see average MPG reported by actual owners.
❌ Mistake: Ignoring 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 expenses. For example, a $25,000 SUV that gets 20 MPG may cost more annually than a $30,000 SUV that gets 35 MPG.
What to do instead: Use total cost of ownership calculators to compare vehicles over 5 years. Factor in fuel, insurance, maintenance, depreciation, and tax incentives.
❌ Mistake: Overlooking Charging Infrastructure (for EVs)
Why it’s bad: Buying an electric SUV without reliable home charging or access to public stations can lead to range anxiety and inconvenience, especially on long trips.
What to do instead: Assess your charging options before purchasing. Install a Level 2 home charger if possible, and research public charging networks like Electrify America or Tesla Superchargers in your area.
❌ Mistake: Choosing AWD Unnecessarily
Why it’s bad: All-wheel drive adds weight and mechanical complexity, reducing fuel economy by 1–3 MPG on average. If you don’t need it, you’re paying for capability you won’t use.
What to do instead: Opt for front-wheel drive unless you live in a snowy or mountainous region. Many modern FWD SUVs offer excellent traction with electronic stability control.
❌ Mistake: Skipping the Test Drive
Why it’s bad: Fuel economy isn’t the only factor—comfort, visibility, and driving dynamics matter too. A car that feels cramped or handles poorly can make daily driving unpleasant.
What to do instead: Always test drive multiple models. Pay attention to seat comfort, noise levels, acceleration, and how the vehicle responds in real traffic.
❌ Mistake: Not Researching Incentives and Rebates
Why it’s bad: Federal, state, and local incentives can significantly reduce the cost of hybrids and EVs. Missing out on these can mean paying thousands more than necessary.
What to do instead: Check the U.S. Department of Energy’s Alternative Fuels Data Center or PlugStar for current incentives. Some states offer additional rebates, tax credits, or HOV lane access.
❌ Mistake: Buying Based on Looks Alone
Why it’s bad: A stylish SUV may have poor fuel economy, limited cargo space, or reliability issues. Prioritizing aesthetics over function can lead to buyer’s remorse.
What to do instead: Make a list of must-have features (e.g., MPG, cargo space, safety ratings) and prioritize them over design. Use reviews and ratings to validate your choices.
