Xiaomi has just given the EV world a new endurance benchmark to argue about.
Its updated SU7 sedan has gone further in 24 hours than any mass-produced electric car before it.
And it didn’t just edge past the competition, it reset the conversation entirely.
Because the car it beat was already considered the one to beat.

How Xiaomi’s SU7 ran for 24 hours
The updated Xiaomi SU7 has officially set a new EV endurance record by covering 2,650 miles (4,264km) in 24 hours.
That’s enough distance to make your legs hurt just thinking about it.
The previous record belonged to the Xpeng P7, which managed 2,460 miles (3,961km) in the same test back in 2025.
Impressive at the time… until Xiaomi showed up and kept driving.
The test happened at a closed track in Yancheng, China, and the rules were simple: keep the car moving for a full day.
The SU7 only stopped to charge, then jumped straight back on track.
A pure test of endurance.
What makes this even better is that this wasn’t a science experiment.
Xiaomi says the car used was production-spec, meaning it’s basically the same one customers can buy later this year.
Powering the run is the SU7 Max’s 897V electrical system and a 101.7kWh battery.
Translation: it can charge very, very fast.
We’re talking peak charging speeds of around 530kW, which is why the car didn’t lose much time sitting still.
It also helps that the SU7 packs serious punch.
The dual-motor setup pushes out 681 horsepower and can hit 165mph – way more than anyone needs for the school run, but perfect for a test designed to break cars mentally and mechanically.
By the end of the 24 hours, Xiaomi wasn’t just ahead.
It was in a different league.

This record claims a lot more bragging rights
This kind of test hits differently from a brochure range figure.
On paper, the updated SU7 Max claims up to 520 miles (835km) on China’s CLTC cycle.
Impressive, sure – but endurance runs like this are harder to dismiss.
They show how an EV behaves when pushed, charged repeatedly, and kept under stress for an entire day.
Heat, battery stress, charging speed – all the boring stuff that actually matters shows up here.
That’s especially important for Xiaomi, which is still proving it belongs in the car world.
The updated SU7 goes on sale in China in April 2026, and this run sends a clear message: this isn’t just a phone company playing dress-up with cars.
It’s a reminder that EVs aren’t only about cruising anymore.
