Volvo EX90: Initial Impressions and EPA Rating

Assessing the Flagship Electric SUV

The Volvo EX90 is Volvo's big swing at the all-electric luxury SUV market. It's supposed to blend comfort with eco-friendliness. This thing is heavy, around 5,400 pounds! The goal is a smooth ride and the benefits of electric power. A major selling point is the EPA range rating: 310 miles on a full charge, but that's specifically for models with 21-inch wheels. It also boasts DC fast charging up to 250 kilowatts, which should make road trips easier. But, as we know, official numbers don't always match reality. Let's see how the EX90 does outside the lab.

Understanding EPA Range Projections

The EPA range is a good starting point, but it's not the whole story. It's based on a mix of city and highway driving. Real-world conditions can change things a lot. Here are some factors that can affect the actual range:

• Speed: Higher speeds use more energy.

• Temperature: Cold weather can reduce battery performance.

• Driving style: Aggressive driving drains the battery faster.

• Load: Extra weight in the car also reduces range.

The EPA's testing is standardized, but it can't account for every possible situation. That's why real-world testing is so important. It gives us a better idea of what to expect in everyday driving.

Beyond Laboratory Conditions

So, what happens when the EX90 hits the road? Kris Rifa, an EV expert, did a real-world highway range test. He rented a new EX90 in Spain to see how it performed. The test model was the Performance version with 21-inch wheels, the one with the 310-mile EPA rating. He drove at a steady 75 mph (120 km/h) on a highway. To account for hills, he drove in a loop, balancing uphill and downhill sections. The test started and ended at the same DC fast charging station. The weather was good, with light winds and about 68°F (20°C). After the test, the EX90 showed an average energy use of 2.38 miles per kWh, or 26 kWh per 100 km. With the EX90's usable battery of 107 kWh, that means a real-world range of about 254 miles. That's a pretty big difference from the EPA number. The 2025.5 Volvo XC90 B6's technology is lacking. The 2025 Volvo XC90 T8 achieved 25 miles on electric power.

Real-World Highway Range Test: The Numbers Don’t Lie

Kris Rifa's Independent Assessment

So, this guy Kris Rifa, who's really into EVs, got his hands on a brand-new Volvo EX90 in Spain. He wanted to see what it could really do on the highway. The model he tested was the Performance version, the one with the 21-inch wheels that's supposed to get 310 miles according to the EPA. It's always interesting to see how these things hold up in the real world, right?

Methodology for Consistent Results

Rifa's test was pretty straightforward. He drove at a steady 75 mph (120 km/h) on a highway in Spain. To make sure hills didn't mess things up, he drove in a loop, so any uphill parts were balanced out by downhill parts. He started and ended at the same charging station. The weather was perfect, about 68 degrees Fahrenheit (20 degrees Celsius), with just a little wind. This kind of controlled testing is key to getting reliable data.

Analyzing Energy Efficiency Metrics

After his drive, the EX90 showed an average energy use of 2.38 miles per kWh, or 26 kWh per 100 km. Since the EX90 has a usable battery of 107 kWh, that means a real-world range of about 255 miles at 75 mph. But, if you figure in about 3% for energy losses, that drops a bit to 247 miles. Here's a quick breakdown:

Metric	Value
EPA Rated Range (21-inch wheels)	310 miles
Real-World Range at 75 mph	255 miles
Real-World Range (with 3% loss)	247 miles
Average Energy Efficiency	2.38 miles/kWh
Usable Battery Capacity	107 kWh

While 247 miles is okay for a big SUV that weighs 5,400 pounds, it's still quite a bit less than the 310 miles the EPA says it should get. The EPA test includes both city and highway driving, which usually gives better range numbers than just driving fast on the highway. It's important to consider highway range when planning long trips.

It's worth noting that the EX90's own energy consumption display was pretty close to the EPA's estimate, showing 2.38 miles/kWh compared to the EPA's 2.5 miles/kWh. This suggests that the difference between the EPA rating and the real-world range might be mostly because of the higher speed used in Rifa's test. If you drive slower, you'll probably get better energy efficiency and more range. It all comes down to how you drive, really. Also, consider the Tesla Model 3 range for comparison.

Discrepancies and Future EV Efficiency Testing

Bridging the Gap Between EPA and Reality

It's no secret that EPA electric vehicle range estimates often don't match what drivers experience in the real world. The EPA conducts its tests in controlled lab environments, which don't always reflect the varied conditions of everyday driving. This can lead to a significant difference between the advertised range and the actual range you get on the road. Closing this gap is crucial for building trust and managing expectations among EV buyers.

Impact of Sustained High Speeds

One major factor contributing to range discrepancies is sustained high speeds. EVs, like all vehicles, consume more energy at higher speeds due to increased aerodynamic drag. The EPA's testing procedures may not fully account for the energy drain that occurs when driving at consistent highway speeds, especially above 70 mph. This is why independent tests, like those conducted by Kris Rifa, are so important. They provide a more realistic assessment of EV performance under typical driving conditions.

InsideEVs' Upcoming Test Protocols

At InsideEVs, we're committed to providing transparent and reliable EV efficiency data. To that end, we're constantly refining our testing protocols to better reflect real-world driving scenarios. Our future tests will focus on:

• Incorporating variable speed testing to simulate mixed driving conditions.

• Evaluating the impact of different climate control settings on range.

• Analyzing the effects of regenerative braking on energy efficiency.

We believe that by adopting more comprehensive and rigorous testing methods, we can provide consumers with the information they need to make informed decisions about EV purchases. Our goal is to bridge the gap between lab results and real-world experiences, ensuring that EV buyers have a clear understanding of what to expect from their vehicles.

We plan to conduct our own tests when we get our hands on the EX90, and we’ll be sure to share our findings. The Volvo EX90, with its blend of luxury and electric efficiency, remains a compelling option for those seeking a sustainable and comfortable ride.

Electric Car Models with Disappointing Ranges

It's exciting to see more and more electric vehicles hitting the market, but it's also important to be realistic about their performance. While some EVs are exceeding expectations, others are falling short of their advertised range, especially in real-world conditions. InsideEVs' testing aims to highlight these discrepancies, providing consumers with the information they need to make informed decisions.

InsideEVs' 2024 Test Highlights

InsideEVs conducted tests on a range of electric vehicles in 2024 to assess their real-world highway range. The testing included models from various manufacturers, offering a broad view of the current EV landscape. The goal was to compare the EPA estimates with actual performance under consistent driving conditions. The test included 11 vehicles from different brands, including the Tesla Model 3, Kia EV9, BYD Seal and Toyota bZ4X.

Significant Range Drops on Highways

One of the most notable findings from the tests was the significant drop in range experienced by some models when driven on highways. Several factors contribute to this, including higher speeds, wind resistance, and the energy required to maintain a constant speed. This is a crucial point for consumers who frequently take long trips, as the advertised range may not be achievable in these situations. The Volkswagen ID.7, for example, can see its range drop by up to 36% during a highway journey.

Examining Specific Vehicle Performance

Here's a look at some specific models and their performance during the InsideEVs' tests:

• Volkswagen ID.7: Showed a substantial decrease in range compared to its EPA estimate.

• Toyota bZ4X: Toyota's legacy facing modern expectations.

• BYD Seal: Entering a competitive market, is it a misstep?

• Kia EV9: An ambitious all-electric SUV in terms of design and technology.

It's important to remember that these tests represent a snapshot of performance under specific conditions. Individual results may vary depending on driving style, weather, and other factors. However, the data provides a valuable point of reference for potential EV buyers.

Here's a table summarizing the range discrepancies observed in some of the tested models:

Model	Theoretical range (WLTP)	Real range (test)	Difference (%)
Tesla Model 3	721 km	650 km	-10%
Kia EV9	500 km	450 km	-10%
BYD Seal	600 km	540 km	-10%
Volkswagen ID.7	620 km	400 km	-36%

Understanding real-world range is essential for managing expectations and planning trips effectively. As electric vehicle technology progresses into 2025, real-world testing reveals urban ranges can exceed 340 miles, but cold weather may reduce range by up to 40%, varying by model and usage. These findings are relevant as electric vehicle technology progresses. It's also important to consider how the Zeekr X electric vehicle has disappointed an Australian driver due to its failure to achieve its advertised range, leading to a frustrating ownership experience.

Factors Influencing Real-World EV Autonomy

Impact of Climatic Conditions

Okay, so let's talk about weather. It's a bigger deal than you might think when it comes to how far your EV can actually go. Cold weather is a notorious range killer, but extreme heat can also impact battery performance. Think about it like this: your phone battery drains faster when it's freezing or scorching outside, right? Same principle applies to EVs.

• Cold temperatures reduce battery capacity and increase energy consumption for heating.

• Hot temperatures can lead to battery degradation over time.

• Some EVs have better thermal management systems than others, which helps mitigate these effects.

It's not just about the temperature itself, either. Things like snow, rain, and wind resistance can all play a role in reducing your EV's range. Plan accordingly, especially if you live in an area with harsh winters or summers.

Driving Style and Energy Consumption

Your driving habits have a HUGE impact on your EV's range. If you're constantly flooring it and slamming on the brakes, you're going to drain the battery much faster than someone who drives smoothly and anticipates traffic. Aggressive driving is fun, sure, but it's not exactly efficient. Consider these points:

• Smooth acceleration and deceleration driving efficiency conserves energy.

• High speeds increase wind resistance and energy consumption.

• Using regenerative braking helps recapture some energy and extend range.

Accessory Use and Battery Performance

Don't forget about all the extra stuff you're running in your car! Air conditioning, heating, headlights, the radio – it all adds up. While modern EVs are designed to be relatively efficient, using these accessories still draws power from the battery and reduces your overall range. Here's the breakdown:

• Heating and air conditioning are the biggest culprits, especially in extreme temperatures. Using the heated seats can be more efficient than blasting the heater.

• Headlights consume a noticeable amount of power, especially at night. Consider using energy-efficient LED headlights if possible.

• Even charging your phone or using the infotainment system impacts of ambient temperature can have a small effect on range.

Accessory	Impact on Range	Notes
Air Conditioning	Moderate	Can reduce range by 10-20% in hot weather.
Heating	Significant	Can reduce range by 20-40% in cold weather.
Headlights	Minor	LED headlights are more efficient than traditional halogen bulbs.
Infotainment System	Minor	Using navigation and streaming services consumes additional energy.

Keep in mind that driving dynamics also play a role. The heavier the load, the more energy the car needs to move. So, try to travel light when possible!

Models Emerging with Competitive Autonomy

It's not all doom and gloom in the EV world! While some models struggle to live up to their range promises, others are exceeding expectations and proving that competitive autonomy is achievable. These vehicles showcase advancements in battery technology, energy management, and overall design.

Vehicles Exceeding Range Expectations

Some EVs consistently outperform their EPA estimates in real-world testing. This can be due to a variety of factors, including efficient powertrain design, optimized aerodynamics, and effective thermal management systems. These are the EVs that are making waves and changing perceptions about EV range.

Renault Megane E-Tech's Strong Showing

The Renault Megane E-Tech has been a pleasant surprise for many EV enthusiasts. It's a great example of a car that delivers on its promises, offering a compelling combination of range, performance, and practicality. It's not just about the numbers; it's about the overall driving experience and how well the car integrates into daily life. The Megane E-Tech is a strong contender in the competitive EV market, showing that you don't need to break the bank to get a reliable electric vehicle.

Identifying Top Performers in EV Efficiency Testing

Identifying the top performers requires a close look at the data. It's not just about the highest range number, but also about consistency and efficiency across different driving conditions. Here are some key factors that set these models apart:

• Efficient Powertrain: Optimizing the motor, inverter, and transmission for maximum energy efficiency.

• Aerodynamic Design: Reducing drag to minimize energy consumption at higher speeds.

• Advanced Battery Management: Precisely controlling battery temperature and charge/discharge cycles to maximize range and lifespan.

It's important to remember that real-world range can vary depending on individual driving habits and environmental conditions. However, these top performers consistently demonstrate their ability to deliver competitive autonomy, making them a smart choice for EV buyers.

Here's a quick look at some models that have shown promise:

Model	Observed Highway Range (miles)

These models are setting a new standard for electric car performance.

Comparative Analysis of EV Range Performance

Theoretical Versus Real-World Figures

It's no secret that the range you see advertised for an EV and what you actually get can be pretty different. This difference is a key factor for many potential buyers. It's not just about the numbers; it's about understanding why those numbers don't always match up in the real world. Factors like driving style, weather, and even the type of tires you have can all play a role. The gap between theoretical and real-world range is something that needs to be considered when you're thinking about buying an electric car.

Understanding Percentage Differences

When we talk about range differences, it's helpful to look at the percentage drop. Some cars might only lose a small percentage of their advertised range, while others can see a much bigger drop. For example, InsideEVs' 2024 tests showed that some cars, like the Volkswagen ID.7, could see their range drop by as much as 36% on the highway. That's a pretty significant difference! Other models, like the Renault Megane E-Tech, have shown a smaller difference between theoretical and real-world range. Understanding these percentage differences can help you make a more informed decision about which EV is right for you.

Here's a simplified example of how range can differ:

Model	Theoretical Range (WLTP)	Real Range (Test)	Difference (%)
Tesla Model 3	721 km	650 km	-10%
Kia EV9	500 km	450 km	-10%
BYD Seal	600 km	540 km	-10%
Volkswagen ID.7	620 km	400 km	-36%
Renault Megane E-Tech	470 km	410 km	-12.77%

Implications for Prospective Buyers

So, what does all this mean if you're thinking about buying an EV? Well, it means you need to do your homework. Don't just rely on the advertised range. Look for real-world tests and reviews. Consider your own driving habits and the conditions you'll be driving in. Are you mostly driving on the highway, or are you doing a lot of city driving? Do you live in a cold climate? All of these things can affect your electric vehicle ranges. Also, remember that InsideEVs conducts independent testing to provide a more accurate picture of EV performance. By taking all of these factors into account, you can make a more informed decision and choose an EV that will actually meet your needs.

It's important to remember that EV range is not a fixed number. It's a range, and it can vary depending on a lot of different factors. Don't be afraid to ask questions and do your research before you buy. The more you know, the better prepared you'll be to make the right choice.

Optimizing Electric Vehicle Range and Performance

Best Practices for EV Owners

Okay, so you've got an EV. Now what? Getting the most out of it isn't just about plugging it in. It's about understanding how to drive it, care for it, and tweak a few things to really maximize that range. Think of it like this: you wouldn't run a marathon without training, right? Same goes for your EV. Let's optimize electric and hybrid vehicle performance.

• Drive smoothly: Avoid jerky acceleration and hard braking. Seriously, pretend you've got a cup of coffee on the dash.

• Use regenerative braking: Get familiar with how it works in your car and use it to your advantage. It's free energy!

• Plan your routes: Knowing where charging stations are located can ease range anxiety.

Maximizing Battery Longevity

Your EV's battery is its heart, and keeping it healthy is key to long-term performance. Batteries degrade over time, but there are things you can do to slow that process down. It's not rocket science, but it does require a little bit of attention. Think of it as preventative care for your car's most important component. Here's the deal:

• Avoid extreme charging levels: Try to keep your battery between 20% and 80% most of the time. Full charges and complete discharges put extra stress on the battery.

• Limit DC fast charging: While convenient, frequent DC fast charging can generate heat that degrades the battery over time. Use it sparingly.

• Keep it cool (or warm): Extreme temperatures aren't great for batteries. Park in the shade during hot days and in a garage during freezing nights, if possible.

Driving Habits for Enhanced Efficiency

How you drive has a HUGE impact on your EV's range. It's not just about speed; it's about consistency and anticipation. Small changes in your driving style can add up to significant gains in efficiency. It's like learning to play an instrument – small adjustments make a big difference. Remember to maximize electric vehicle range by adopting these habits:

• Maintain a steady speed: Highway speeds can drain your battery quickly. Try to stick to the speed limit and use cruise control when appropriate.

• Anticipate traffic: Look ahead and try to avoid sudden braking. Coasting to a stop is much more efficient than slamming on the brakes.

• Use eco mode: If your car has an eco mode, use it! It typically reduces acceleration and optimizes other systems for efficiency. You can optimize your electric car's range by using this mode.

Driving an EV efficiently is a bit of a mindset. It's about being mindful of your energy consumption and making small adjustments to your driving habits. Over time, these changes become second nature, and you'll be amazed at how much further you can go on a single charge.

The Future of EV Efficiency Testing and Standards

Evolving Measurement Methodologies

The way we test EVs is changing, and it needs to. The old methods just don't cut it anymore when it comes to reflecting how these cars perform in the real world. We're seeing a push for more dynamic testing that takes into account things like varying speeds, different terrains, and even driver behavior. It's not enough to just run a car on a dyno in a lab; we need to see how it handles rush hour traffic or a long road trip. The goal is to create testing procedures that give consumers a much clearer picture of what they can expect from their EV.

Addressing Real-World Driving Scenarios

EV testing needs to get real. We need to move beyond ideal conditions and start throwing some curveballs at these cars. Think about it: how does an EV perform when it's hauling a trailer up a mountain pass? What happens to the range when you're battling a headwind on the highway? These are the kinds of scenarios that drivers face every day, and they need to be factored into the testing process. By simulating these conditions, we can get a much better understanding of an EV's true capabilities and limitations. This will help consumers make informed decisions and avoid any unpleasant surprises down the road.

Collaborative Efforts for Accuracy

Improving EV efficiency testing isn't something that any one organization can do alone. It requires a collaborative effort between automakers, testing agencies, and regulatory bodies. We need to share data, compare results, and work together to develop testing standards that are both accurate and relevant. This also means being transparent about the testing process and making the results publicly available. By working together, we can improve testing accuracy and build trust in the EV market.

The future of EV testing hinges on collaboration and transparency. By working together, we can develop standards that accurately reflect real-world performance and empower consumers to make informed decisions.

Here are some key areas where collaboration is essential:

• Data Sharing: Automakers should share real-world performance data with testing agencies.

• Standard Development: Collaborative efforts to create standardized testing procedures.

• Transparency: Publicly available test results to build consumer trust.

And here's a look at how the market is expected to grow:

Year	Market Size (Millions)
2024	$410.9
2034	$2,210

This growth highlights the need for better battery testing and certification.

Ultimately, the goal is to create a testing ecosystem that provides consumers with the information they need to make informed decisions about buying and using EVs. This means embracing new technologies, innovative testing techniques, and a collaborative spirit to ensure that EV efficiency testing is as accurate and relevant as possible.

Wrapping Things Up

So, what have we learned from all this testing? Well, it's pretty clear that while official range numbers are a good starting point, they don't always tell the whole story. Things like how fast you drive, the weather, and even if you're blasting the AC can really change how far your EV goes. Our tests, and others like them, help show what you can actually expect when you're out on the road. It's not about saying one car is bad and another is good, but more about giving you a clearer picture. Knowing the real-world range helps everyone make smarter choices, whether you're buying an EV or just planning your next trip. We'll keep doing these tests, so stay tuned for more honest numbers.
