• Impressive efficiency and range 
• Question marks over reliability
• Small dealer network, but it will grow in time

What are the running costs?

Efficiency is a real high point of the Xpeng, and an area where it’s up there with the best. In Standard Range form, Xpeng claims a range of 270 miles from its 66kWh battery, though we haven’t spent time with this car yet. 

The one we have thoroughly tested, however, is the Long Range model, predicted to be the most popular. It packs a larger 87kWh battery that enables a claimed range of 354 miles. On paper that’s behind the 387 miles claimed by the Tesla Model Y in its longest-range form, but we were hugely impressed by the Xpeng’s efficiency in our testing.

In normal driving with a mix of rural and town driving it averaged 4mi/kWh efficiency. That’s impressive for an electric SUV of this size and gives a range just about matching what Xpeng claims (the car was tested in March in temperatures around 10 degrees – see why temperature can affect an EV’s range). At constant motorway speeds, when electric cars are normally at their most inefficient, the range fell to around 280 miles, but that’s still plenty for longer trips. 

It can also be very fast to charge, with max DC charging speeds of 280kW enabling a 10 to 80 per cent charge in 20 minutes if you can find a fast enough charger. 

Servicing and warranty

At the time of writing (July 2025), Xpeng had only just launched in the UK and was slowly growing its dealer network, with plans to have 20 showrooms up and running by the end of 2025, though it says it is ‘appointing a nationwide aftersales network’ to go alongside its dealers. 

Xpeng’s warranty is fairly average by EV standards, lasting five years or 75,000 miles (whichever comes first). That lags behind Kia’s seven-year, 100,000-mile cover, and though Hyundai’s warranty lasts the same number of years, there is no mileage cap on it, making it well-suited to high-mileage drivers.

Service intervals on the Xpeng G6 are every 12 months or 12,000 miles (whichever comes first). The firm was unable to provide a cost for servicing at the time of writing.  

Reliability

Xpeng is considered one of China’s most innovative car makers, and we’ve struggled to find anything to suggest its cars have proven unreliable in its home country, though UK reliability data is unavailable. If you own an Xpeng we encourage you to leave an owner’s review to help inform other readers.
