What to Look for When Buying Buying Guide
1. Real-World Fuel Economy Ratings
When shopping for a fuel-efficient third-row SUV, don’t rely solely on the EPA’s window sticker. While official ratings provide a useful baseline, they’re often optimistic and don’t always reflect real-world driving conditions. Look for independent testing from sources like Consumer Reports, Edmunds, or Car and Driver, which conduct their own fuel economy tests under varied conditions—city, highway, mixed driving, and even with a full load of passengers and cargo. A vehicle that scores 28 mpg combined on paper might drop to 23–25 mpg in everyday use, especially if you frequently drive in stop-and-go traffic or carry heavy loads. Pay close attention to city mileage, as that’s where most families rack up the majority of their miles. Also, consider whether the SUV offers an Eco mode or adaptive cruise control with stop-and-go functionality, as these features can significantly improve real-world efficiency.
2. Powertrain Type: Hybrid, Plug-in Hybrid, or Conventional?
The type of engine under the hood plays the biggest role in determining fuel economy. In 2026, your options are more diverse than ever:
– Conventional gasoline engines are still common, especially in budget-friendly models. Look for turbocharged four-cylinders or efficient V6s with cylinder deactivation and start-stop technology. These can deliver decent mileage, especially on the highway.
– Hybrid systems (like Toyota’s Hybrid Synergy Drive or Ford’s Intelligent Hybrid) combine a gasoline engine with an electric motor and battery. They excel in city driving, where regenerative braking recaptures energy. Most hybrids don’t need to be plugged in and can achieve 30+ mpg combined.
– Plug-in hybrids (PHEVs) offer the best of both worlds: electric-only driving for short commutes (typically 20–40 miles) and a gasoline engine for longer trips. If you have access to home charging, a PHEV can drastically reduce fuel costs and emissions. However, they’re heavier and more expensive upfront.
– Mild hybrids use a small electric motor to assist the engine but can’t run on electric power alone. They offer modest fuel savings (5–10%) and are often found in luxury models.
Choose based on your driving patterns. If you mostly drive short distances in the city, a hybrid or PHEV is ideal. For long highway commutes, a well-tuned conventional engine might suffice.
3. Vehicle Size and Weight
It’s simple physics: bigger, heavier vehicles require more energy to move. While third-row SUVs are inherently larger than compact crossovers, there’s still a wide range in size and weight. Compact three-row SUVs like the Hyundai Santa Fe or Kia Sorento weigh around 4,000–4,300 pounds, while full-size models like the Chevrolet Tahoe or Ford Expedition can exceed 5,500 pounds. Heavier vehicles not only consume more fuel but also have longer braking distances and reduced handling agility. When comparing models, check the curb weight and look for lightweight construction materials like high-strength steel, aluminum hoods, or composite body panels. Also, consider wheel size—larger wheels (20” or above) can reduce fuel economy due to increased rolling resistance.
4. Aerodynamics and Design
You might not think of aerodynamics when shopping for a boxy SUV, but it matters—especially at highway speeds. A vehicle with a low drag coefficient (Cd) slices through the air more efficiently, reducing the engine’s workload. Look for features like active grille shutters (which close at high speeds to reduce drag), underbody panels, and streamlined rooflines. Some manufacturers even use computational fluid dynamics (CFD) to optimize airflow. For example, the 2026 Toyota Highlander Hybrid has a Cd of 0.32, which is impressive for its class. While you won’t find a Cd rating on every window sticker, reputable reviews often mention aerodynamic improvements. Avoid models with excessive roof racks, spoilers, or bulky accessories unless you plan to remove them when not in use.
5. Transmission and Drivetrain Efficiency
The transmission plays a crucial role in fuel economy. Modern automatics with 8, 9, or even 10 speeds can keep the engine in its most efficient RPM range. Continuously variable transmissions (CVTs) are also common in hybrids and smaller SUVs because they offer seamless acceleration and optimal engine speed. Avoid older 4- or 5-speed automatics, which are outdated and less efficient. Drivetrain choice also matters: front-wheel drive (FWD) is typically more fuel-efficient than all-wheel drive (AWD), but AWD provides better traction in snow or rain. Some models offer AWD disconnect systems that send power only to the front wheels when AWD isn’t needed, improving mileage. If you live in a mild climate, consider whether AWD is truly necessary—opting for FWD could save you 1–2 mpg.
6. Third-Row Usability and Cargo Flexibility
Fuel economy isn’t just about the engine—it’s also about how you use the vehicle. A third row that’s cramped or difficult to access can lead to underuse, meaning you’re carrying dead weight that hurts efficiency. Look for SUVs with sliding second-row seats, wide rear doors, and easy-fold mechanisms. Some models, like the Honda Pilot or Subaru Ascent, offer “walk-through” access to the third row, making it easier for kids or elderly passengers to get in and out. Cargo space is equally important. A fold-flat third row and adjustable cargo floor can help you optimize load distribution, which affects aerodynamics and weight. Also, consider whether the third row folds completely flat—some only fold in a 60/40 split, leaving a hump that limits usability.
7. Technology and Driver Assistance Features
Modern fuel-efficient SUVs come loaded with tech that can indirectly improve fuel economy. Adaptive cruise control with stop-and-go helps maintain a steady speed and reduces unnecessary acceleration and braking. Eco-driving modes adjust throttle response, transmission shifts, and climate control to maximize efficiency. Some models even offer predictive energy management, using GPS data to anticipate hills or traffic and adjust powertrain output accordingly. While these features won’t turn a gas guzzler into a hybrid, they can add 1–3 mpg in real-world driving. Additionally, infotainment systems with real-time fuel economy displays can help you develop more efficient driving habits. Just be mindful of battery-draining features like heated seats, large screens, and premium audio systems—use them sparingly to preserve efficiency.
8. Brand Reputation and Long-Term Reliability
Fuel economy isn’t just about the first year—it’s about how well the vehicle holds up over time. Some brands are known for building durable, efficient powertrains that maintain their performance for 150,000+ miles. Toyota and Honda, for example, have long track records of hybrid reliability. Hyundai and Kia have made significant strides in recent years, offering strong warranties and efficient engines. On the other hand, some luxury brands prioritize performance over efficiency, and their complex systems may require costly repairs down the line. Check reliability ratings from J.D. Power, Consumer Reports, and RepairPal. Also, consider resale value—a vehicle that holds its value well (like a Toyota Highlander) can offset higher upfront costs through better trade-in or sale prices.
Different Types of Buying Guide
Common Buying Mistakes to Avoid
❌ Mistake: Prioritizing Horsepower Over Efficiency
Why it’s bad: A high-horsepower engine might sound impressive, but it often comes with poor fuel economy, higher emissions, and increased maintenance costs. Many buyers are swayed by “300+ horsepower” ads, only to realize they’re burning through gas on daily commutes.
What to do instead: Focus on torque and real-world performance. A turbocharged four-cylinder with 250 hp can feel just as responsive as a V6 with 300 hp, especially in city driving. Look for engines with broad torque curves and efficient transmissions.
❌ Mistake: Ignoring the Third Row’s Practicality
Why it’s bad: Some third-row seats are so cramped they’re only usable by small children or for short trips. If you regularly transport adults or teens, a cramped third row can lead to discomfort and frequent complaints.
What to do instead: Test the third row yourself. Bring a friend or family member to sit in the back during a test drive. Check legroom, headroom, and ease of access. Look for models with sliding second-row seats that allow you to adjust space between rows.
❌ Mistake: Overlooking Maintenance and Repair Costs
Why it’s bad: A fuel-efficient SUV might save you money at the pump, but if it requires expensive repairs or specialized parts, those savings vanish. Hybrids and PHEVs, for example, may need battery replacements after 8–10 years.
What to do instead: Research long-term ownership costs. Use tools like Edmunds’ True Cost to Own or Kelley Blue Book’s 5-Year Cost to Own. Factor in fuel, insurance, maintenance, and depreciation. Choose brands with strong dealer networks and affordable parts.
❌ Mistake: Choosing AWD When FWD Suffices
Why it’s bad: All-wheel drive adds weight, complexity, and reduces fuel economy by 1–2 mpg on average. If you live in a region with mild winters and good roads, AWD may be unnecessary.
What to do instead: Assess your actual need for AWD. If you rarely drive in snow or off-road, opt for front-wheel drive. Some models offer AWD as an optional upgrade—skip it unless you truly need it.
❌ Mistake: Skipping the Test Drive
Why it’s bad: Fuel economy specs and reviews can’t tell you how a vehicle feels on the road. A smooth ride, responsive steering, and quiet cabin can make long drives more enjoyable, even if the mpg isn’t the highest.
What to do instead: Always take a test drive, preferably with a full load of passengers and cargo. Pay attention to noise levels, suspension comfort, and how the vehicle handles curves and bumps. A comfortable SUV is one you’ll actually want to drive.
❌ Mistake: Falling for “Eco” Badges Without Verification
Why it’s bad: Some manufacturers slap “Eco” or “Green” badges on models that aren’t significantly more efficient than standard versions. These are often marketing gimmicks.
What to do instead: Compare EPA ratings side by side. Look for actual improvements in mpg, not just branding. Check if the “Eco” model includes real efficiency features like low-rolling-resistance tires or aerodynamic tweaks.
❌ Mistake: Not Considering Resale Value
Why it’s bad: A vehicle that depreciates quickly can cost you thousands when it’s time to trade in or sell. Even if it’s fuel-efficient, poor resale value hurts your long-term budget.
What to do instead: Research resale value using Kelley Blue Book or Edmunds. Brands like Toyota, Honda, and Subaru typically hold their value well. Avoid niche models or those with limited dealer support.

Expert Tips for Getting the Best Deal
– Time your purchase strategically: Dealerships often offer the best incentives at the end of the model year (August–October) or during holiday sales events like Memorial Day or Black Friday. You can also score deals when new model-year inventory arrives.
– Shop online first: Use tools like TrueCar, Edmunds, or Cars.com to compare prices across dealers. Many offer no-haggle pricing and home delivery, saving you time and stress.
– Negotiate based on invoice price: Know the dealer’s invoice price (what they paid the manufacturer) and aim to pay close to it. Use competing offers as leverage.
– Consider certified pre-owned (CPO): A CPO SUV can save you 15–20% off the price of a new one while still offering warranty coverage and thorough inspections. Look for models that are 1–3 years old with low mileage.
– Check for tax credits and rebates: Plug-in hybrids and electric SUVs may qualify for federal tax credits (up to $7,500) or state incentives. Even some hybrids offer rebates in certain states.
– Read the fine print on warranties: Some brands offer longer powertrain warranties (e.g., Hyundai’s 10-year/100,000-mile coverage). Make sure you understand what’s covered and for how long.
– Test drive multiple models: Don’t settle for the first SUV you like. Compare at least three options to see how they differ in ride quality, noise, and usability.
– Factor in total cost of ownership: Use online calculators to compare fuel, insurance, maintenance, and depreciation over 5 years. A cheaper SUV might cost more in the long run.
