The longest-range electric SUVs available today

The Mercedes EQS SUV, BMW iX xDrive50, and Tesla Model X Long Range currently lead the market in maximum driving range, each rated for over 300 miles per charge by the EPA. The Mercedes EQS SUV 580 reaches up to 453 miles, the BMW iX xDrive50 reaches 380 miles, and the Tesla Model X Long Range reaches 348 miles. However, real-world range depends heavily on driving conditions, temperature, and how you drive — highway speeds and cold weather both reduce the distance you can travel.

Range figures come from EPA testing, which uses a standardized procedure but does not account for individual driving habits. A vehicle rated for 350 miles might deliver 280 miles in winter or at highway speeds, or 380 miles in mild weather with gentle acceleration. Manufacturer claims sometimes exceed EPA ratings, so the EPA number is the more reliable figure for planning.

Key Takeaways

  • The Mercedes EQS SUV 580 offers the longest EPA-rated range at 453 miles, followed by the BMW iX xDrive50 at 380 miles and Tesla Model X Long Range at 348 miles.
  • EPA range ratings assume mixed driving and do not account for cold weather, highway speeds, or aggressive acceleration, all of which reduce actual range by 15 to 30 percent.
  • Battery size, motor efficiency, and aerodynamics determine range; larger batteries and more efficient motors go farther, but also cost more and add weight.
  • Charging speed and charger availability matter as much as range for long trips, since a 300-mile SUV with slow charging is less practical than a 250-mile SUV with fast charging access.

How EPA range testing works and why real-world distance differs

The EPA tests electric vehicles on a dynamometer (a machine that simulates driving) using a five-cycle procedure that includes city driving, highway driving, and cold-weather conditions. The test assumes moderate acceleration, no extreme weather, and a mix of speeds. A vehicle that passes this test receives an EPA range rating, which is the distance the EPA estimates it can travel on a full charge under those conditions.

Real-world range typically falls short of the EPA rating because actual driving includes factors the test does not fully capture. Sustained highway speeds above 60 mph increase energy use significantly. Temperatures below 40°F reduce battery efficiency and can cut range by 20 to 30 percent. Aggressive acceleration, towing, and driving on hilly terrain all consume more energy. Conversely, gentle city driving in mild weather can sometimes exceed the EPA estimate.

To estimate what you might actually see, subtract 15 to 25 percent from the EPA rating for typical mixed driving, and subtract 30 to 40 percent if you plan mostly highway trips in winter. This is not a may provide — your actual range will vary — but it is a more realistic planning figure than the EPA number alone.

Battery size and efficiency: what determines range

An electric SUV's range depends on three main factors: battery capacity (measured in kilowatt-hours, or kWh), motor efficiency, and aerodynamic design. A larger battery stores more energy and allows the SUV to travel farther, but it also weighs more, costs more, and takes longer to charge. The most efficient motors convert more of that stored energy into motion rather than heat, and a streamlined body shape reduces wind resistance at highway speeds.

The Mercedes EQS SUV achieves its 453-mile range partly through a very large battery (up to 107.8 kWh usable capacity) and partly through an efficient electric motor and low drag coefficient. The Tesla Model X uses a smaller battery (around 100 kWh) but achieves competitive range through a highly efficient motor and aerodynamic design. The BMW iX xDrive50 balances a large battery with dual motors, which provide all-wheel drive but use more energy than a single motor.

When comparing range between models, look at both the EPA rating and the battery size. A vehicle with a 100 kWh battery rated for 350 miles is more efficient than one with a 120 kWh battery rated for 350 miles — the second one wastes more energy to achieve the same distance. Efficiency matters because it determines how far you can go on a charge and how much it costs to drive per mile.

Long-range electric SUVs at different price points

Long-range electric SUVs start around $60,000 and extend well above $100,000. The Tesla Model Y Long Range (around $55,000 to $65,000 depending on options) offers 330 miles of EPA range and is one of the most affordable long-range options. The Hyundai Ioniq 7 (starting around $55,000) will offer up to 300 miles when it launches. The Kia EV9 (starting around $55,000) reaches 304 miles in its longest configuration.

Mid-range options include the Volkswagen ID.Buzz (around $59,000 to $69,000) with up to 260 miles, the Chevrolet Blazer EV (around $50,000 to $65,000) with up to 293 miles, and the Ford Mustang Mach-E Extended Range (around $52,000 to $65,000) with up to 312 miles. Premium options like the BMW iX xDrive50 (around $100,000) and Mercedes EQS SUV (around $105,000 and up) offer the longest ranges but at significantly higher cost.

Price and range do not always move together. Some less expensive models achieve competitive range through efficient design rather than massive batteries. Before choosing based on range alone, compare the total cost of ownership — purchase price, available tax credits (which vary by income and vehicle), electricity costs, and maintenance — over the years you plan to own the vehicle.

Charging speed and infrastructure: why range alone is not enough

A 450-mile SUV is only useful if you can charge it when you need to. Charging speed depends on the charger type: a Level 1 charger (standard 120-volt household outlet) adds about 3 miles of range per hour, a Level 2 charger (240-volt home or public charger) adds 25 to 30 miles per hour, and a DC fast charger adds 150 to 200 miles in 20 to 30 minutes. For long trips, DC fast charger availability matters more than maximum range.

A 300-mile SUV with access to DC fast chargers every 150 miles is more practical for road trips than a 450-mile SUV in an area with few fast chargers. Before buying, check the locations of DC fast chargers along routes you drive regularly using apps like PlugShare, A Better Route Planner, or the charger networks' own apps (Tesla Supercharger, Electrify America, EVgo, Ionity, and others). Some networks are more reliable or widespread than others depending on your region.

Home charging is equally important. If you can install a Level 2 charger at home, you can charge overnight and start each day with a full battery, which means range matters less for daily driving. If you cannot install home charging, you will rely more on public chargers, and a longer-range vehicle becomes more valuable because it reduces how often you need to charge away from home.

Cold weather, towing, and other factors that reduce range

Winter driving can reduce range by 20 to 40 percent depending on temperature and how much you use the cabin heater. Cold batteries are less efficient, and heating the cabin (which uses electricity rather than waste engine heat, as in gas vehicles) consumes significant energy. Preheating the cabin while plugged in before you drive helps, as does using seat heaters instead of cabin heat when possible.

Towing reduces range substantially — typically by 30 to 50 percent depending on the trailer weight and aerodynamics. If you plan to tow regularly, add that loss to your planning. Driving at highway speeds (65 mph and above) also reduces range compared to city driving, because wind resistance increases with speed. Driving at 75 mph instead of 55 mph can reduce range by 20 to 30 percent.

Tire pressure, weight, and driving style all matter. Underinflated tires increase rolling resistance and reduce range. Carrying heavy cargo reduces range. Aggressive acceleration and hard braking waste energy. If you drive gently, maintain tire pressure, and avoid highway speeds, you can often exceed the EPA estimate. If you drive aggressively or at high speeds, expect to fall short.

How to choose a long-range electric SUV for your needs

Start by identifying your actual range requirement. If you drive mostly within 200 miles of home and charge at home overnight, a 250-mile SUV is sufficient. If you take frequent road trips or live in an area with limited charging, aim for 300 miles or more. If you tow regularly or live in a cold climate, add 50 to 100 miles to your target to account for real-world losses.

Next, check charging infrastructure along your regular routes and any trips you plan to take. A vehicle's maximum range is irrelevant if you cannot charge it where you need to. Use PlugShare or A Better Route Planner to map DC fast chargers on routes you drive, and verify that the charger networks you find are reliable in your area.

Then compare total cost of ownership, not just purchase price. Factor in available federal tax credits (up to $7,500 in the US, though income and vehicle price limits explore), state or local credits, electricity costs (typically $0.03 to $0.05 per mile depending on local rates), and maintenance (electric vehicles have fewer moving parts and lower maintenance costs than gas vehicles). A more expensive vehicle with lower electricity costs and higher efficiency may cost less to own over five or ten years.

Finally, test drive the vehicles you are considering. Real-world driving feel, cabin comfort, infotainment system usability, and cargo space matter as much as range. A vehicle with slightly less range but better comfort and features may be the better choice for your situation.

Frequently Asked Questions

Can I really drive 450 miles on a single charge in a Mercedes EQS SUV?

The EPA rates the Mercedes EQS SUV 580 at 453 miles, but that assumes mixed city and highway driving in moderate conditions. Real-world range depends on your driving style, weather, and speed. Highway driving in cold weather might deliver 300 to 350 miles instead. The EPA rating is a useful comparison tool, but plan for 15 to 25 percent less in typical conditions.

Does cold weather really reduce range that much?

Yes. Temperatures below 40°F reduce battery efficiency and increase cabin heating load, which together can cut range by 20 to 40 percent. Preheating the cabin while plugged in helps, as does using seat heaters instead of cabin heat. In very cold climates, a vehicle rated for 300 miles might deliver 200 miles in winter.

What is the difference between EPA range and manufacturer range claims?

EPA range comes from standardized testing and is more conservative. Manufacturers sometimes publish their own range figures based on different testing methods, which often show higher numbers. When comparing vehicles, use EPA ratings for consistency. Manufacturer claims can be useful context, but EPA numbers are more reliable for planning.

Do I need the longest-range SUV, or is 250 miles enough?

It depends on your driving. If you charge at home and drive mostly within 150 miles of home, 250 miles is sufficient. If you take frequent road trips or live in an area with sparse charging, 300 miles or more is more practical. Consider your longest regular trip and add 50 miles as a safety margin, then choose a vehicle that meets that target.

How much does it cost to charge an electric SUV compared to gas?

Electricity costs vary by region, but typically range from $0.03 to $0.05 per mile, compared to $0.10 to $0.15 per mile for gas at current prices. Charging at home is usually cheaper than public charging. Over 100,000 miles, the fuel cost difference can be $5,000 to $10,000 in your favor, though this varies by local electricity rates and gas prices.
