Understanding EV Range: What Does “Highest Mileage” Really Mean?

When we talk about “mileage” for electric cars, we’re really talking about their driving range. This is the total distance an EV can travel on a full battery charge. It’s similar to how a gasoline car’s mileage is measured by how far it can go on a full tank of gas.

Several factors influence an EV’s range:

• Battery Size: A larger battery (measured in kilowatt-hours, kWh) generally means a longer range. Think of it like a bigger gas tank.
• Aerodynamics: How easily a car cuts through the air affects how much energy it uses. Sleek designs are more efficient.
• Weight: Lighter cars use less energy to move.
• Tire Efficiency: Special low-rolling-resistance tires help conserve energy.
• Driving Style: Aggressive acceleration and braking use more energy than smooth driving.
• Environmental Conditions: Cold weather can reduce battery performance and therefore range. Using the heater also consumes energy.
• Speed: Driving at higher speeds requires more energy.

The most common way to compare EV range is by looking at the EPA estimated range. The Environmental Protection Agency (EPA) tests cars under standardized conditions to give consumers a comparable measure of efficiency and range. However, remember that your real-world mileage might vary based on the factors listed above.

The Current Leaders: EVs with the Highest Estimated Mileage

The electric vehicle market is constantly evolving, with new models and improved battery technology emerging regularly. However, as of late 2023 and early 2024, a few standout models consistently offer the longest ranges. These vehicles are often luxury sedans or models designed with efficiency as a top priority.

Here are some of the top EVs known for their exceptional mileage:

Please note that these figures are EPA estimates and can vary based on specific trims, options, and driving conditions. It’s always a good idea to check the latest specifications from the manufacturer.

Deep Dive: The Lucid Air Grand Touring

The Lucid Air has made waves in the EV industry for its incredible range. The Grand Touring model, in particular, stands out. Lucid Motors, a relatively new player, has focused heavily on aerodynamic efficiency and advanced battery technology. Their “DreamDrive” advanced driver-assistance system also adds to the premium experience.

What makes the Lucid Air so efficient? It’s a combination of factors:

• Sleek Design: The Air has a very low drag coefficient, meaning it slips through the air with minimal resistance.
• Advanced Powertrain: Lucid’s in-house electric motors are designed for high efficiency.
• Battery Technology: They use advanced battery pack design and thermal management.

For drivers who prioritize maximum distance between charges, the Lucid Air Grand Touring is currently the benchmark.

The Tesla Stalwarts: Model S and Model 3

Tesla has long been a leader in EV range. The Tesla Model S Long Range continues to be a top performer, offering a blend of luxury, speed, and impressive mileage. Its well-established Supercharger network also provides a significant advantage for long-distance travel.

The Tesla Model 3 Long Range offers a more accessible entry point into long-range EVs. While it might not reach the extreme numbers of the Lucid Air, its 358-mile EPA estimate is more than enough for most daily driving and many road trips. It’s a testament to how efficiently Tesla can pack range into a smaller, more affordable package.

Luxury and Range: Mercedes-Benz EQS and BMW i7

Luxury automakers are also stepping up their EV game. The Mercedes-Benz EQS 450+ Sedan is a prime example, offering a sophisticated and comfortable experience with a substantial range of up to 350 miles. Its focus is on a serene driving experience and high-quality interior.

Similarly, the BMW i7 xDrive60 brings BMW’s renowned driving dynamics and luxury to the electric era. While its range might be slightly lower than some competitors, it still provides a very capable long-distance journey for those seeking premium comfort and performance.

Beyond the Top Tier: Other Long-Range EV Options

While the Lucid Air, Teslas, and Mercedes EQS often grab the headlines for their range, several other EVs offer excellent mileage and might be a better fit depending on your budget, size needs, and brand preference.

SUVs and Crossovers with Good Range

The demand for electric SUVs and crossovers is huge. Fortunately, manufacturers are delivering. While SUVs are generally less aerodynamic than sedans, some are achieving impressive ranges:

• Hyundai IONIQ 5 (Long Range RWD): Offers up to 303 miles.
• Kia EV6 (Long Range RWD): Similar to the IONIQ 5, with up to 310 miles.
• Ford Mustang Mach-E (California Route 1 Extended Range RWD): Can achieve up to 312 miles.
• Volkswagen ID.4 (Pro S RWD): Offers around 291 miles.
• Tesla Model Y Long Range: A popular choice, with an EPA estimate of around 330 miles.

It’s important to note that all-wheel-drive (AWD) versions of these SUVs typically have slightly lower ranges than their rear-wheel-drive (RWD) counterparts due to the added weight and energy consumption of the second motor.

Electric Trucks

Electric trucks are a newer segment, but some are already offering competitive ranges. The GMC Hummer EV Pickup is a notable example, with its large battery pack enabling significant mileage. However, its size and weight mean that its efficiency isn’t as high as smaller EVs. Other electric trucks like the Ford F-150 Lightning and Rivian R1T also offer substantial range, particularly in their extended-range configurations.

Affordable EVs with Decent Range

You don’t always need to spend a fortune to get good EV range. Models like the Chevrolet Bolt EV/EUV (though phasing out, they offer excellent value) and the Nissan Leaf (in its longer-range versions) provide accessible options for many buyers, with ranges often exceeding 200 miles, which is ample for most daily commutes.

Factors Affecting Your Real-World EV Range

As mentioned earlier, the EPA estimates are a great starting point, but your actual driving experience will differ. Understanding these variables can help you manage expectations and plan your trips effectively.

1. Temperature

Cold weather is the biggest enemy of EV range. Batteries become less efficient in the cold, and you’ll likely use more energy to heat the cabin. Many EVs have heat pumps, which are more efficient than traditional resistive heaters, but they still consume energy. In very cold conditions, you might see a 10-30% reduction in range.

Hot weather can also affect range, though usually to a lesser extent. Running the air conditioning will use energy, and extreme heat can impact battery performance. However, preconditioning your car (cooling or heating it while plugged in) can help mitigate this.

2. Driving Speed

This is a universal truth for all vehicles: the faster you go, the more fuel (or electricity) you use. Aerodynamic drag increases exponentially with speed. Driving at 75 mph will consume significantly more energy than driving at 60 mph. For maximum range, keeping your speed moderate is key.

3. Driving Style

Smooth acceleration and braking are your friends when maximizing EV range. Jackrabbit starts and hard braking waste energy. Most EVs offer regenerative braking, which captures energy normally lost as heat during braking and sends it back to the battery. Using one-pedal driving (where available) maximizes this effect.

4. Terrain and Load

Driving uphill requires more energy than driving on a flat road. Similarly, carrying heavy loads or towing a trailer will reduce your range. The extra weight means the motors have to work harder.

5. Tire Pressure and Type

Underinflated tires increase rolling resistance, making the car less efficient. Ensure your tires are properly inflated according to the manufacturer’s recommendations. Some EVs come with special low-rolling-resistance tires designed for maximum efficiency.

6. Using Accessories

While the impact is usually less significant than heating or cooling, using other accessories like heated seats, infotainment systems, or even charging your phone will draw power from the battery.

How to Maximize Your EV’s Range

Want to get the most miles out of every charge? Here are some practical tips:

• Drive Smoothly: Accelerate gently and anticipate stops to utilize regenerative braking effectively.
• Maintain Moderate Speeds: Stick to the speed limit or slightly below, especially on highways.
• Proper Tire Inflation: Check your tire pressure regularly and keep it at the recommended level.
• Precondition Your Cabin: While plugged in, set your desired cabin temperature so the battery doesn’t have to work as hard when you start driving.
• Use Eco Mode: Most EVs have an “Eco” or “Range” mode that adjusts throttle response and climate control for better efficiency.
• Minimize Weight: Remove unnecessary items from your car.
• Plan Your Route: Use navigation apps that consider elevation changes and traffic to optimize your journey.

Choosing the Right EV for Your Needs

When deciding which EV is “best” for you, consider more than just the maximum mileage:

• Your Daily Commute: Most daily commutes are well under 50 miles. Even an EV with a 200-mile range is more than sufficient.
• Long-Distance Travel Habits: If you frequently take long road trips, a higher-range EV is crucial.
• Charging Availability: Do you have access to home charging? What’s the charging infrastructure like in your area and along your typical routes?
• Budget: EVs with the highest ranges often come with a premium price tag.
• Vehicle Type: Do you need a sedan, SUV, or truck?
• Features and Comfort: Consider interior space, technology, and driving experience.

The “best” EV is the one that fits your lifestyle and budget while meeting your range requirements. For many, an EV with a 250-300 mile range is perfectly adequate, offering peace of mind without the highest cost.
