The longest-range electric SUVs available today

The Mercedes EQS SUV and BMW iX xDrive50 currently lead the market with EPA-estimated ranges above 300 miles per charge. The Mercedes EQS 450+ reaches 312 miles, while the BMW iX xDrive50 achieves 324 miles. The Tesla Model X Long Range delivers 348 miles, making it the longest-range three-row electric SUV you can buy right now. These figures come from EPA testing, which measures range under standardized conditions—real-world distance varies based on driving habits, weather, and terrain.

Range leadership shifts as manufacturers release new models and update battery packs. The Lucid Gravity, which began deliveries in 2024, claims EPA estimates around 516 miles for its base model, though independent testing and real-world data are still accumulating. The Kia EV9 offers up to 304 miles in its Long Range trim. If you are shopping now, focus on EPA estimates rather than manufacturer claims, because EPA numbers reflect what owners actually see on the road.

Key Takeaways

  • The Tesla Model X Long Range currently delivers the longest EPA-estimated range among widely available three-row electric SUVs at 348 miles per charge.
  • Mercedes EQS SUV and BMW iX xDrive50 both exceed 300 miles of range and offer luxury features, though they cost significantly more than Tesla's offering.
  • Real-world range depends on driving speed, outside temperature, terrain, and how much cargo you carry, so EPA estimates are a starting point, not a may provide.
  • Newer models like the Lucid Gravity claim higher ranges, but independent verification and long-term owner data take time to accumulate after launch.
  • Charging infrastructure and charging speed matter as much as total range when planning trips, because a 300-mile SUV with slow charging is less practical than a 250-mile SUV with fast charging.

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

The EPA tests electric vehicles on a dynamometer—a machine that simulates driving without the vehicle moving—using a standardized cycle that includes city, highway, and mixed driving. The test runs at moderate speeds and temperatures, which is why EPA estimates tend to be higher than what owners report in winter or at highway speeds. Cold weather reduces range by 20 to 40 percent because the battery loses efficiency and the cabin heater draws significant power. Highway driving at 70 mph or faster also cuts range compared to city driving, because aerodynamic drag increases with speed.

Your actual range depends on several factors you control. Aggressive acceleration and hard braking waste energy. Carrying heavy cargo or towing reduces range. Using climate control—heating or air conditioning—drains the battery faster than the EPA test accounts for. Driving on hilly terrain costs more energy than flat roads. If you live in a cold climate or regularly drive on the highway, subtract 15 to 25 percent from the EPA estimate to get a realistic number for your situation.

Three-row versus two-row electric SUVs and range trade-offs

Three-row electric SUVs are heavier and less aerodynamic than two-row models, which means they use more energy per mile. The Tesla Model X Long Range (three rows) achieves 348 miles, while the Tesla Model Y Long Range (two rows) reaches 330 miles—similar battery, but the heavier X uses more power. The Kia EV9 (three rows, 304 miles) versus the Kia EV6 (two rows, 310 miles) shows the same pattern. If you do not need a third row, a two-row electric SUV will go farther on the same battery size, or you can choose a smaller battery and save money.

The trade-off is seating and cargo space. A three-row SUV seats up to seven and carries more luggage. A two-row model seats five and has less room behind the rear seats. If your household is small or you rarely use the third row, a two-row electric SUV is the more efficient choice. If you regularly transport more than five people or need maximum cargo capacity, the range penalty of a three-row model is worth it.

Charging speed and how it affects practical range on long trips

A 300-mile electric SUV is only useful on long trips if you can recharge quickly. The Tesla Model X Long Range supports up to 250 kW DC fast charging at Tesla Superchargers, which adds roughly 175 miles in 20 minutes. The BMW iX xDrive50 charges at up to 195 kW on DC fast chargers, adding about 140 miles in 20 minutes. The Mercedes EQS SUV reaches 200 kW, delivering similar speed. The Kia EV9 charges at up to 233 kW, making it one of the fastest in its class.

On a cross-country trip, charging speed matters more than total range. An SUV with 250 miles of range and 200 kW charging can complete a 500-mile day with two 20-minute stops. An SUV with 350 miles of range but only 100 kW charging requires longer stops or more frequent stops. Check the charging network along your planned routes—Tesla Superchargers are the densest in North America, but other networks like Electrify America and EVgo are expanding. If you frequently take long trips, factor in charging time, not just range.

Price and battery size: what you actually pay for range

Longer range costs money because it requires a larger battery pack. The Tesla Model X comes in three versions: the Model X (260 miles, starting around $55,000), the Model X Long Range (348 miles, starting around $65,000), and the Model X Plaid (348 miles, starting around $75,000). The jump from base to Long Range adds roughly $10,000 for 88 extra miles—about $114 per mile of range. The jump from Long Range to Plaid adds $10,000 but does not add range; it adds performance.

The Mercedes EQS 450+ (312 miles) starts around $105,000, while the EQS 580 (453 miles) starts around $130,000. That $25,000 difference buys 141 miles of range, or about $177 per mile. The Kia EV9 Long Range (304 miles) starts around $55,000, making it one of the best value options for range per dollar. Before choosing the longest-range model, ask yourself how often you drive more than 250 miles in a day. If the answer is rarely, a mid-range model saves money and still covers your actual needs.

Comparing range across different vehicle sizes and types

Electric SUVs are not the only long-range electric vehicles. The Tesla Model S Long Range (sedan) reaches 405 miles, and the Tesla Model 3 Long Range (sedan) reaches 358 miles. Sedans are lighter and more aerodynamic than SUVs, so they go farther on the same battery. If you do not need SUV height or cargo space, a sedan delivers more range for less money. The Chevrolet Blazer EV (midsize SUV) reaches 293 miles, while the Chevrolet Equinox EV (compact SUV) reaches 319 miles—the smaller vehicle goes farther because it weighs less.

Truck-based electric vehicles sacrifice range for towing capacity. The Ford F-150 Lightning (extended range) reaches 312 miles, which is respectable but lower than comparable SUVs because trucks are heavier and less aerodynamic. The Chevrolet Silverado EV claims 400 miles, though it has not yet reached customers. If towing is not essential, an electric SUV delivers more range than an electric truck of similar price.

Battery degradation and how range changes over time

Electric vehicle batteries lose capacity slowly over years and miles. Most manufacturers warranty their batteries for 8 years or 100,000 miles, guaranteeing that capacity will not drop below 70 percent. Real-world data from Tesla owners shows that batteries typically lose 5 to 10 percent of capacity in the first 100,000 miles, then stabilize. A Model X with 348 miles of range might deliver 315 miles after 100,000 miles—a noticeable but manageable loss.

You can slow battery degradation by avoiding frequent fast charging, keeping the battery between 20 and 80 percent charge, and parking in shade or a garage rather than in direct sun. If you plan to keep your electric SUV for 10 years or more, expect to lose 15 to 20 percent of range by the end of that period. If you trade in or sell after 5 to 7 years, degradation will be minimal and will not significantly affect resale value.

Frequently Asked Questions

Can I really drive 300 miles in an electric SUV without stopping?

Yes, but only if conditions are ideal—moderate temperature, highway speeds below 65 mph, light cargo, and flat terrain. In winter, at 75 mph, or with a full load, you will see 20 to 40 percent less range. Plan to charge when you reach 20 percent battery remaining, which means stopping before you hit the EPA estimate.

Which electric SUV has the best charging network?

Tesla has the densest Supercharger network in North America, with over 50,000 chargers. Non-Tesla vehicles can access Tesla Superchargers through adapters, but availability varies by region. Electrify America and EVgo are expanding but have fewer locations. Check the charging map for your region before buying.

Is a 250-mile electric SUV enough for daily driving?

For most owners, yes. The average American drives 40 miles per day, so a 250-mile SUV covers a week of driving on one charge. Long trips require planning and charging stops, but daily commuting and errands are no problem. If you drive more than 100 miles most days, a longer-range model is worth the extra cost.

Does towing reduce electric SUV range as much as it does in gas vehicles?

Yes, and sometimes more. Towing adds weight and aerodynamic drag, both of which increase energy use. Most electric SUVs lose 20 to 40 percent of range when towing, depending on trailer weight and speed. If you tow regularly, subtract 40 percent from the EPA estimate to plan realistically.

Should I buy the longest-range model even if I do not need it?

Not necessarily. The longest-range models cost $10,000 to $20,000 more and take longer to charge because of larger batteries. If you drive fewer than 200 miles most days and have access to home charging, a mid-range model saves money and still meets your needs. Reserve the longest-range models for people who regularly drive 250+ miles or live in areas with sparse charging infrastructure.
