Australian EV Sales Hit 25% in June as 32,500 Deliveries Set Record

Q: Advertised EV ranges are often wrong; which popular models fall shortest on real Australian roads?

On Australian roads, the biggest range misses in recent AAA real-world testing were BYD models, with the BYD Atto 3 Essential and BYD Dolphin Premium among the worst performers in the latest round. The Australian Automobile Association’s Real-World Testing Program found none of the 20 EVs it assessed matched their laboratory range claims. In the June 2026 results, the BYD Atto 3 Essential fell 20% short, delivering 328km against a claimed 410km. The BYD Dolphin Premium was close behind, at 398km versus 490km, a 19% gap. Other popular models also underperformed, though less severely. The Kia EV5 Earth LR AWD returned 446km against a 500km claim, an 11% shortfall. The Kia EV9 Air RWD managed 395km versus 443km, also 11% down. The Tesla Model Y Long Range AWD came closest in that batch, reaching 559km against a 600km claim, a 7% gap. Earlier AAA testing showed even larger misses for some mainstream EVs. The 2023 MG4 Standard Range recorded the widest gap reported, at 281km versus a 405km WLTP claim, a 31% shortfall. The 2023 BYD Atto 3 was 23% short, at 369km versus 480km. A 2025 BYD Dolphin Essential was also reported at 24% below claim, with 313km against 410km. Experts say these gaps are mainly about test-cycle optimism and real driving conditions such as speed, temperature, terrain and air-conditioning use, rather than battery degradation.

Q: If mileage doesn't predict battery failure, what is the hidden risk every used EV buyer must check for?

The key hidden risk is not high mileage but **battery cell imbalance and the battery’s true state of health**. Experts say odometer readings are a weak guide to EV battery risk because failure can come from a bad cell or module rather than gradual wear. That means a near-new EV can need a battery replacement, while a very high-mileage one can still perform well. The bigger danger for a used buyer is a pack with uneven cells, hidden faults, or a poor charging and heat history that does not show up in normal service records. That is why buyers should insist on a **battery health check**, not just a road test. The important evidence is the battery’s state of health, cell balance, fault codes, charging history, thermal exposure, remaining warranty, and any software or battery service history. Motoring groups such as RACV have also stressed checking warranty status and software support, because battery issues may be covered only within the manufacturer’s terms. This matters because modern EV batteries generally degrade slowly—studies cited in the report put average annual capacity loss around 1.8% to 2.3%—and many retain more than 80% capacity beyond 200,000 kilometres. So the main used-car risk is less about normal ageing and more about **hidden pack condition**. In practice, the safest move is an independent battery report or manufacturer diagnostic before purchase. That is the best way to uncover whether the battery is healthy, balanced and still protected by warranty.

Battery electric vehicles captured nearly one in four new-car sales in Australia in June, jumping from 7.6% a year earlier as more than 32,500 units were delivered in a record month.
1.8% annual battery-capacity loss in newer EVs, down from 2.3% in 2019, is helping erode a key buyer fear that ageing packs will fail early and require costly full replacement.
80% capacity beyond 200,000 kilometres was retained by most heavily driven EVs in one analysis, while researchers said modern pack design increasingly allows cheaper module-level repairs instead of full battery swaps.
5% to 11% WLTP range shortfalls still showed real-world driving often falls below advertised figures, though experts said that gap reflects conditions such as speed, weather and terrain rather than battery degradation.
Eight-year or 160,000-kilometre battery warranties remain standard, and with fuel costs also driving demand, industry and motoring groups say battery health will become a central check in Australia's growing used-EV market.

Australia's Electric Vehicle Market Surges: EVs Reach 30% of New Car Sales in 2026 Amid Chinese Brand Boom

Overview

Australia’s electric vehicle market saw a historic surge in June 2026, with momentum driven by the strong performance of brands like BYD, which ranked second nationally for the third month in a row. This success highlights a robust and growing demand for electric vehicles, positioning BYD ahead of many traditional and hybrid competitors. The market’s rapid transformation is fueled by the increasing influence of Chinese EV manufacturers, technological advancements, and shifting consumer preferences. Together, these factors signal a powerful trajectory for Australia’s automotive sector, marking a significant shift towards electric mobility and a new era for the industry.
