The Nio ET7 just completed a 648-mile journey on a single charge

Remember the wild Nio EP9 electric performance car? Well, the Chinese marque has now started to really show its versatility by completing a 648-mile (1,044km) journey with its ET7 saloon, using up around 97 per cent of its battery power. Yep, there was still plenty of juice left over for a coffee run at the end of it.

The 14-hour drive began in the manufacturer’s home city of Shanghai and ran along China’s east coast to Xiamen, with a three-man team including Nio CEO and chairman, William Li, alternating between shifts behind the wheel and annoying the driver with terrible music choices. We made that last bit up. 

Despite cold temperatures - so often associated with reducing EV range - the ET7 managed to complete the trip without the need for a battery swap or a recharge, which Nio says is a testament to the ‘true capabilities’ of its all-new Ultra Long Range battery. 

Said battery is a 150kWh unit and has a cell energy density of up to 360Wh/kg. In layman’s terms, this makes it the most high capacity and energy-dense battery currently being mass-produced in China. 

Speaking on the milestone, Li said: “The completion of this range test marks the range of smart EVs going beyond 1,000 kilometres, which will further promote the transformation of the automotive industry from the consumption of gasoline to electricity.”

This isn’t the first time an electric car has completed a journey of over 1,000km either. Back in the summer of 2022, the Mercedes Vision EQXX concept car travelled from Stuttgart to Silverstone and smashed the single charge record with a distance of 1,202km. It even had enough charge remaining for not one, but two coffee runs afterwards.
