Deciding when to trade in an electric vehicle (EV) is a question many owners face as their cars age and new models hit the market. CleanTechnica recently gathered insights from Tesla and BYD Atto 3 drivers to understand the factors influencing their decisions. Their experiences highlight how battery health, comfort, and evolving technology shape the timing of an EV trade-in.
How Long Do EVs Really Last?
The Tesla Model 3 featured in the article is now seven years old, with over 180,000 km (~112,000 miles) on the odometer. Despite this high mileage, both the author and other owners report only minor battery degradation—about 10% loss in range. Nathan Merritt of Ride4U stated he would consider trading in his Model 3 after 700,000 km (~435,000 miles), showing that many EVs can remain reliable far beyond traditional expectations.
Unlike older petrol cars, which often required major repairs after 100,000 miles (~160,000 km), modern EVs benefit from fewer moving parts and improved materials. Owners note that components like gearboxes, timing belts, and water pumps—common sources of trouble in combustion vehicles—are not concerns for EVs.
Why Owners Decide to Trade In
For some, the decision to trade in is driven by personal needs rather than vehicle limitations. The author is moving from a Model 3 to a Model Y, citing easier entry and exit as a key factor due to age-related mobility changes. Others, like Neil Warner, prefer to stay within the manufacturer’s warranty period or seek vehicles that better match their comfort and range requirements.
Battery technology and creature comforts are common priorities. Don, a BYD Atto 3 owner, plans to upgrade to the Atto 3 EVO, noting that battery advancements and improved comfort features are important for his next purchase.
Competitor Comparison
The Tesla Model 3 and Model Y are often compared with the BYD Atto 3, especially in markets like Australia. Don observed that the Atto 3 offered better battery technology than Tesla at its launch, though Tesla has since improved its battery safety packages. Neil Warner highlighted that the Model Y Performance offers greater ground clearance (157 mm vs. 140 mm for the Model 3 Long Range Dual Motor), easier rear seat access, and more cargo space due to its hatchback design.
Historical Context
Tesla’s global sales have grown from 22,477 units in 2013 to 1,789,226 vehicles in 2024. However, Model Y sales saw a -3.1% year-over-year decline in 2024. This context shows that while EV adoption is rising, owners are keeping their vehicles longer, reflecting confidence in long-term reliability.
Regional Availability
The experiences shared are primarily from Australian owners, where both Tesla and BYD have a strong presence. The growing number of EV options in Australia is giving buyers more choices, with new models and battery technologies entering the market each year.
Why this matters
These real-world experiences challenge common fears about EV longevity and battery degradation. Owners are finding that EVs can remain practical and reliable well past 100,000 miles (~160,000 km), with only minor range loss. The decision to trade in is increasingly about personal comfort, new features, and lifestyle needs rather than technical limitations.
As more models become available and battery technology continues to improve, EV owners have greater flexibility in choosing when to upgrade.
What this means for buyers
If you’re considering when to trade in your EV, focus on your personal needs—such as comfort, warranty coverage, and desired features—rather than worrying about battery failure. Most modern EVs can easily surpass 180,000 km (~112,000 miles) with minimal degradation. With more choices and improved technology, buyers can confidently keep their EVs longer or upgrade when the right model comes along.
