If you’ve spent any time in an EV forum, you’ve heard it all before: “This car charges at 350 kW!” or “This one does 800 kilometers on a charge!” But in the real world—where temperatures fluctuate, chargers age, and batteries heat up—those manufacturer promises often melt faster than a lithium pack under peak load.
So Germany’s ADAC decided to put a little truth serum into the mix. Their approach was refreshingly simple: simulate a long-distance trip across the autobahn, include a single fast-charging stop, and measure what actually happens—not what glossy sales brochures claim should happen.
The result? A surprisingly shuffled hierarchy of long-distance champions, proving once again that usable long-range performance isn’t just about battery size. It’s about chemistry, thermal management, efficiency… and, critically, how long a car can sustain fast-charging speeds, not just the number a manufacturer brags about on paper.
How ADAC Measured the Real Winners
Each EV was run under identical conditions, driven through 90% of its usable battery, then plugged into a fast charger for exactly 20 minutes. ADAC then combined the pre-charge and post-charge totals into a single “grand-touring range” metric.
The magic of this test? It reflects what drivers actually experience: start driving, recharge briefly, and keep going. No lab conditions. No fantasy numbers.
And the outcome produced a top-10 list where several cars crossed the 800-kilometer barrier—one even flirted with a thousand.
The Top Performers: Real-World Range Royalty
1. Porsche Taycan Performance Plus – 981 km (513 + 468 km)
The Taycan didn’t just win—it dominated. Porsche’s 97-kWh sports sedan delivered a staggering 981 kilometers of total travel, pairing solid baseline range with unmatched charging stamina. Its 468 kilometers gained in a single 20-minute session was the highest of the entire test, finally silencing anyone who thought Porsche’s vaunted charging curve was marketing hype.
2. Hyundai IONIQ 6 2WD – 931 km (502 + 429 km)
Hyundai continues to embarrass legacy automakers with physics-defying efficiency. Despite having one of the smallest batteries in the test (77.4 kWh), the IONIQ 6 nearly cracked the 1,000-kilometer club. It didn’t just beat bigger, pricier cars—it humiliated them.
3. Audi A6 Avant e-tron Performance – 921 km (524 + 397 km)
Audi’s long-roof EV proved that the brand’s upcoming next-gen electric architecture has serious legs. With over 900 kilometers of combined range, the A6 Avant sits just a whisker behind Hyundai—and does so with a more conventional German luxury demeanor.
Efficiency vs. Battery Size: The Plot Twist
Interestingly, none of the top three were the efficiency kings. Four other EVs actually outperformed the Taycan in pure battery-only range. The surprise leader?
BMW iX xDrive50 – 553 km before charging
Despite weighing roughly as much as a small moon, the iX squeezed the most kilometer-per-kWh results in the group. Credit its massive 111-kWh pack—but also BMW’s excellent highway tuning. Yet its charging recovery (282 km) couldn’t keep pace with Porsche and Hyundai, dropping it to sixth overall.
The Remaining Contenders
Here’s how the rest of the top 10 shook out:
- Audi Q6 e-tron Performance – 884 km (509 + 375 km)
- Lucid Air Grand Touring AWD – 859 km (550 + 309 km)
- BMW iX xDrive50 – 835 km (553 + 282 km)
- Hyundai IONIQ 9 Techniq – 832 km (482 + 350 km)
- Mercedes EQS 450+ – 825 km (521 + 304 km)
- XPeng G6 Long Range – 820 km (454 + 366 km)
- Mercedes EQE SUV 350+ – 806 km (503 + 303 km)
The standout among the final group is the XPeng G6—the only Chinese EV to elbow into the top ten, and with impressive charging recovery to boot.
What This Test Really Shows
EV road-tripping is no longer an experiment—it’s everyday reality. But ADAC’s results highlight some big takeaways:
- Fast-charging curves matter more than peak kW numbers. Sustained power beats momentary spikes.
- Battery size isn’t destiny. Hyundai’s IONIQ 6 proves efficiency can trump capacity.
- Premium brands aren’t guaranteed winners. Porsche and Audi deliver—but Hyundai is right there with them.
- China is coming. XPeng’s appearance in the top 10 won’t be its last.
Long-distance EV travel may still require planning, but range anxiety is rapidly becoming yesterday’s problem. And if Porsche keeps this up, the 1,000-kilometer barrier might not last long.
