G'day and welcome to Plugged in Australia episode 53 for Tuesday the 12th of May 2026. And today we're doing something a little bit different. Hasn't been a massive amount of new EV news around for Australia, so instead of just waffling on about stuff overseas or rehashing old stories, I thought we'd do a proper explainer on one of the most confusing parts of buying an electric vehicle, and that's EV range. Now because if you've ever looked at an electric car and wondered why one website says it can do 700km, another one says 560, and a real world YouTube test gets closer to 430, you're definitely not alone. And this is one of the biggest sources of confusion for EV buyers. The same car can have completely different range figures depending on whether the number comes from China, Europe, America, or Australia. You're gonna hear terms like WLTP, WLTC, EPA, CLTC, and NEDC. And unless you follow this stuff closely, it can just feel like an alphabet soup. So in this episode, we're gonna break it all down properly, we'll cover what the different range tests actually are, how they're done, why the numbers vary so much, and most importantly, which figures Australian buyers should take seriously when comparing EVs. Now if there's just one particular one that you want to know about, check in the episode notes, I will have timestamps there. So you can just skip ahead to the particular test cycle that you're interested in. And once you understand the test cycle behind the number, EV range claims can start to make a whole lot more sense. Let's get into it. One of the biggest shocks for new EV buyers is finding out that the exact same electric vehicle can have several different official range figures. For example, you might see a car advertised overseas with a range of 700km. Then you look at the Australian version and it says 570km. Then you watch an overseas road test and the reviewer gets 440km on the highway. So what's going on? Is the manufacturer lying? Not necessarily. The main reason is that different markets use different official testing systems. China uses the CLTC, Europe uses WLTP, America uses EPA, and older vehicles may still refer to NEDC. And then within WLTP, you'll also hear the term WLTC, which is related but not exactly the same thing. The important thing to understand is that EV range is not measured by someone just driving the car randomly until it stops. Official range figures come from standardized laboratory tests. That's the same basic idea as fuel economy testing for petrol and diesel vehicles. The whole point is consistency. If every manufacturer uses the same test in the market, buyers can compare one car against another. The problem is that different markets don't all use the same test. And each test has a different mix of city driving, highway driving, acceleration, braking, speed and temperature assumptions. That's why a car can look amazing under one test cycle, much less impressive under another. And it's especially confusing here in Australia because we get vehicles from China, Europe, Japan, Korea, and a few from the United States. So Australian buyers are constantly seeing different range numbers from different systems. So, how are EV range figures actually tested? Most official testing is done in a laboratory on something called a chassis dynameter, or dyno for short. That's basically a rolling road. The car is strapped down, the wheels sit on rollers, and the vehicle is driven through a set pattern while computers simulate the load the car would experience on the road. Think of it like a treadmill for cars. The driver doesn't just drive however they want, they follow a very precise speed trace on a screen. The test tells them when to accelerate, when to hold speed, when to slow down, when to stop, and when to start again. A driving pattern is what we call a test cycle. Each cycle tries to represent a certain type of driving. Some include lots of stop start city traffic, some include higher speed highway sections, some are more gentle, some are more demanding, and that is where the different range figures come from. A car that performs extremely well in low speed urban driving might do brilliantly in one test, but look less impressive in another test that includes more sustained highway speeds. That matters because EVs are usually very efficient around town. They can recover energy through regenerative braking, they don't waste energy idling, and lower speeds reduced aerodynamic drag. However, once you get onto a freeway at 100 or 110k an hour, energy consumption rises quickly, and that's why a range figure based heavily on city driving can look much better than what you'll actually see on a long Australian road trip. Temperature also matters. Most official tests are done in controlled conditions, but in the real world your EV might be dealing with a hot summer day, a cold winter morning, rain, strong wind, hills, passengers, luggage, roof racks, or even towing. All of these things can reduce drag. Another important point is that small changes to the vehicle can make a big difference. The same EV with larger wheels can have less range. A performance version can have less range, wider tyres can have less range, extra weight can reduce range, even optional equipment can affect the official result in some testing systems. So official range testing is useful, but it's not perfect. It's designed to help compare cars under controlled conditions. It is not a guarantee that you personally will get that exact number every time you drive. Now, before we talk about the current systems, we need to start with NEDC. NEDC stands for New European Driving Cycle. This was the older European test cycle used for many years, and in simple terms, NEDC was very optimistic. The test was developed in a different era, cars were generally lighter, less powerful, and much simpler. The driving cycle involved gentle acceleration, relatively low average speeds, and driving conditions that didn't really reflect how many people use modern cars. For EVs, NEDC often produced range figures that were very hard to achieve in normal driving. You might see an older EV with a claimed range of 400km NEDC, but in the real world driving it might be much closer to 280 or 300km depending on conditions. And that's why many early EV range claims felt unrealistic. It wasn't always because the car was bad, it wasn't because the test itself was too soft. NEDC also didn't properly reflect modern high-speed driving, heavier vehicles, bigger wheels, and the way people actually accelerate and brake. In Australia, older labelling rules were based around NEDC, so you'll still sometimes see older specifications or older vehicles referring to it. But the industry has largely moved away from NEDC because it simply wasn't realistic enough. And that leads us on to WLTP. So what's the difference? The simple version is that WLTP is the overall testing procedure, and WLTC is the actual driving cycle used within that procedure. In other words, WLTP is the full set of rules, WLTC is the driving pattern the car follows during the test. So if you hear someone say the car was tested under WLTC, they're usually talking about the driving cycle. If you hear someone say the car has a WLTP range, they're usually talking about the final official range figure produced by the broader test procedure. For normal buyers, WLTP is the term you'll see most often. Compared with NEDC, WLTP is much more realistic. It uses a longer test, higher average speeds, more varied acceleration and braking, and a better mix of driving conditions. The WLTC cycle includes four phases low speed, medium speed, high speed and extra high speed. That means it tries to include city driving, suburban driving, rural style driving, and higher speed motorway driving. The highest speed in the test is a bit over 130km per hour, so it does at least include some faster driving. That makes WLTP much more useful than NEDC. But it's still a laboratory test. It's not the same as driving from Sydney to Canberra into a headwind with the air conditioning on, the family in the car, on a set of 21 inch wheels. So for Australians, WLTP is a good comparison figure. It's usually much better than NEDC. It's often achievable in mixed driving, especially around town and suburbs. But if you spend a lot of time on motorways or country highways at 100 or 110 kilometers per hour, your real-world range will usually be lower than the WLTP number. This is the American system. We don't have a lot of American-built EVs here in Australia, but to give you an example of some of them, we've got the three Cadillacs, the Lyric, the Vistic, and the Optic. We also have the Mercedes-Benz EQS SUV. I'm pretty sure as of 2026, they are the only four US-built EVs that are currently sold here. You also have some older Model 3 Teslas that were built in the US up until about early January 2021. After that there were Chinese built ones, but prior to that they were US built ones and would have had the EPA range figures. Now in the EV world, EPA figures are generally seen as more conservative than WLTP. Now that doesn't mean EPA is perfect, but it often gives a more cautious estimate, especially for mixed driving and highway use. The EPA process includes city and highway testing, and the results are adjusted to better account for real-world factors. That's one of the reasons EPA numbers often look lower than WLTP numbers for the same vehicle. As an example, an EV might have a WLTP range of around 560km, but an EPA range of closer to 500km. That can look disappointing at first, but in practice the EPA figure is often closer to what owners might see in normal driving, especially if they do a lot of freeway work. And that's very relevant for Australia. We have long distances, we have hot weather, we have 100 and 110km per hour roads, or 130 if you're going across an oliboard. We have regional trips where you might sit at high speeds for long periods. So while Australia generally sees WLTP quoted more often, EPA is still a really useful benchmark when it's available. If an EV has an EPA rating, I personally treat that as a pretty good conservative estimate. Not a guarantee, but a useful real-world figure. Now we get to the test cycle that causes a lot of confusion at the moment, CLTC. That stands for China Light Duty Vehicle Test. This is the range test cycle used in China. And if you've seen some Chinese EVs claiming enormous range numbers, CLTC is usually the reason. You might see a car advertised in China with 700, 800 or even more than 900km of claimed range. Now on paper, it sounds incredible. But the key question is under which test? CLTC tends to favour low-speed urban and suburban driving. It reflects the type of dense traffic and stop-start driving that is very common in many Chinese cities. And EVs are very good in those conditions. At lower speeds, they use less energy. In stop-start traffic, they can recover energy through regenerative braking, and they don't waste energy idling like a petrol car. So under CLTC, EVs can achieve very high official numbers. The problem is that it doesn't always translate well to Australian driving. If you're commuting around town, the CLTC figure may not be completely meaningless, but if you're driving on the M4, the Hume, the Pacific Highway, the Great Western Highway, or doing regional trips at 110km per hour, the real world range will usually be substantially lower. That's why you need to be careful when comparing a Chinese market CLTC figure with a European WLTP figure or even an American EPA figure. A car with 700km CLTC range is not necessarily a 700km car in Australia. A rough rule of thumb is that CLTC can be around 25 to 30% higher than many drivers might expect in more realistic mixed or highway heavy conditions. It's not an exact formula, it depends on the vehicle, the battery, the tyres, the road, the weather, and how you drive. But it's a helpful warning. If you see a huge Chinese range number, don't take it at face value until you know whether it is CLTC, WLTP or EPA. Alright, now let's put this into a simple explanation. Imagine an EV with a large battery. In China it might be advertised as having 700km of CLTC range. In Europe, the same or similar vehicle might be rated at 580km WLTP. And then in America, if it were tested there, it might be closer to 500km EPA. Then in the real world, Australian highway driving, it might do somewhere around 430 to 500km depending on the conditions. Now that doesn't mean one number is fake and the others are real. It means each test is measuring a different type of driving. CLTC is generally more urban friendly, WLTP is a more balanced lab test, EPA is usually more conservative, and real-world driving is affected by things no lab can test for fully. This is why buyers should not compare range numbers unless they know the test cycle. A 650km CLTC claim is not automatically better than a 520km EPA claim. In some real-world conditions, the EPA-rated car may actually go further. The test cycle matters just as much as the number. Australia is in a slightly awkward position because our market gets vehicles from everywhere. We get Chinese EVs, we get European EVs, we get Korean EVs, we get Japanese EVs, and we get a couple of American EVs. And we have plenty of people quoting American reviews and American EPA figures online. So Australian buyers end up seeing a messy mix of test cycles. Historically, Australian vehicle labels were tied to older ADR labelling rules that used NEDC-based testing. But Australia is moving toward newer WLTP-based labelling. From July 2026, new vehicle models supplied for the first time in Australia will start moving to the updated ADR 81-03 energy consumption labelling rules, and those rules will apply more broadly by July 2028. That could make range and efficiency information clearer over time, but for now you still need to pay attention. When you see an EV range claim, ask one simple question. Which test cycle is that? Is it NEDC? Is it WLTP? Is it EPA? Is it CLTC? Or is it a real-world test? That one question can completely change how you interpret the number. So what should Australian EV buyers actually trust? Here's my simple ranking. If you see NEDC, be very cautious. It's an old test and usually pretty optimistic. If you see CLTC, treat it as a very best case style figure, especially if you're looking at Chinese market information. It may be useful for low-speed city driving, but it is not a great guide for Australian highway range. So if you live and primarily drive in a very dense city area, sort of like Newtown in Sydney, or if you live in Brunswick in Victoria, something like that, and you don't venture out far, very, far very often, then these figures may be pretty useful for you as you are doing exactly the type of driving that the CLTC test cycle is made for. If you see WLTP, that's usually the most relevant figure for Australia. It's not perfect, but it's a decent mixed driving comparison. If you see EPA, that's often the most conservative official number that can be very useful for road trip expectations. And if you see real-world testing from an owner or a reviewer, that can be extremely useful as long as you understand the conditions. Were they driving at 90km per hour or 110? Was it hot? Was it cold? Was it raining? Were they climbing hills? Were they using the AC? Were they testing the base model with the small wheels or the performance model with the big wheels? Because all of that matters. For a basic rule of thumb, WLTP is usually a decent mixed driving estimate. EPA is usually a safer conservative estimate. CLTC should usually be reduced in your head before comparing it with Australian conditions, and NEDC should mostly be treated as an old optimistic number. Even once you understand the test cycles, your actual range can still vary. The biggest factor is speed. EVs are very efficient at low speeds, but at highway speeds, aerodynamic drag becomes a major issue. The faster you go, the more energy the car needs to push through the air. That's why doing 110km per hour can use noticeably more energy than doing 90 or 100. Temperature is another big factor. Cold weather can reduce battery performance and increase energy use for cabin heating. Hot weather can also increase energy use through air conditioning and battery cooling. Then there are tyres and wheels. Bigger wheels often look better, but they can reduce range. Performance tyres can reduce range, roof racks, roof boxes, and towing can absolutely smash the range. Even tyre pressure makes a difference. Weight matters too, but not always as much as people think. In city driving, extra weight can hurt efficiency, however, at highway speeds aerodynamics is usually mattering more. Driving style also plays a huge role. Smooth acceleration and good anticipation can improve range. Hard acceleration, late braking, and high speed driving can reduce it quickly. This is why two owners of the same EV can report very different range results. One person might mostly drive around town and easily get close to the official figure. Another person might be doing long highway trips and wonder why they're 20% below the claim. Both experiences can be true. So if you're shopping for an EV in Australia, here's the practical advice. Don't just look at the biggest range number, look at the test cycle behind it. If a car says 700km, find out whether it's CLTC or WLTP. If it's CLTC, don't compare it directly against a WLTP or EPA figure vehicle. If a car says 500km EPA, don't assume it has worse range than a 600km CLTC car. They may be much closer in the real world than the numbers suggest. Also look at the battery size and efficiency. A car with a bigger battery is not always more efficient, and a car with a smaller battery is not automatically worse if it uses energy more efficiently. Pay attention to watt hours per kilometer or kilowatt hours per 100km if that information is available. That tells you how efficiently the vehicle uses its battery. Also, think about your actual driving. If you mostly drive around town, your real world range might be excellent. If you do regular long distance highway trips, focus more on EPA style figures, WLTP highway impressions and real world road tests. And if you tow, carry heavy loads, use roof racks or drive in regional areas, assume you'll get less than the headline number. That's not an EV problem, it's just physics. Petrol and diesel vehicles also use more fuel when towing, driving fast or carrying extra weight. The difference is that with EVs, people tend to notice it more because range is displayed so clearly on the screen. So the big takeaway from today is simple: not all EV range figures are created equal. NEDC is old and optimistic. CLTC can produce very big numbers, especially for Chinese market EVs. WLTP is a better modern test and the one Australians will most commonly see. WLTC is the actual driving cycle used within the broader WLTP procedure. EPA is the American system and is often much more conservative in its official number. And real-world range depends on how, where and when you drive. So next time you see an EV claiming 700km of range, don't immediately get too excited. But don't admittedly dismiss it either. Just ask, what test cycle is that? Because once you know the test cycle, you know how seriously to take that number in comparison to how you will use the vehicle. And that makes comparing EVs so much easier. And that is it for Plugged in Australia episode 53, this special explainer episode. Hopefully this helped clear up why EV range figures can be so confusing and why one car can have several different official numbers depending on where it's sold. If you found this useful, let me know. I'm thinking about doing some more of these explainer style episodes when there isn't a huge amount of EV news around. Info at pluggedinaustralia.com.au. We could look at things like charging curves, different battery chemistries, your LFP versus your NMC batteries, 400 volt vs 800 volt architectures, battery degradation tunneling with EVs, or how regenerative braking. works. Just some ideas I'll put out there. As always, thank you so much for listening and until the next time stay plugged in and stay charged. Chiva Jammo.
