The Xpeng G6 has entered the rapidly expanding and extremely competitive electric medium SUV segment. 

Priced to compete with the Tesla Model Y at $54,800, before on-road costs, the 2025 Xpeng G6 boasts stats impressive enough to make the Tesla’s $55,900 best-seller sit up and pay attention. 

Under the skin, the G6 uses 800-volt architecture and boasts up to 570km driving range, comparable — if not better — than $20,000 dearer rivals like the Kia EV6 GT-Line RWD ($79,590), Hyundai Ioniq 5 Epiq ($84,300), Ford Mustang Mach-E Premium ($79,990) and Polestar 4 ($78,500, all before on-road costs). 

The significance of Xpeng’s 800-volt electric system is charge time, with owners able to recuperate the larger 87.5kWh lithium-ion (NMC) battery from 10-80 per cent in less than 20 minutes, just as Hyundai-Kia’s E-GMP platform allows. You’ll also find this in luxury vehicles like the Porsche Taycan and its Audi e-tron GT relation.

The question is, how has Xpeng saved the money? Imported by TrueEV in Australia, Xpeng says it is all to do with streamlined production steps — and it’s pleasingly nerdy. 

Like Tesla’s ‘Gigacasting’, Xpeng is moving to simpler vehicle construction, with the SEPA 2.0 platform's one-piece castings integrating 300 individual parts into one element. But there are less visible advancements, too. 

Technical Advisor at TrueEV Andrew Morcos told CarsGuide about the lessons learned from stripping down a G6 to understand its structure and parts make-up. 

“I pulled Mercs apart for years. You've got so many different modules, and they go half copper, half CAN Bus. The way you undo these things, [manufacturers] make it very complicated”, explained Morcos.

Typically, the different modules used by OEMs for various purposes — adaptive cruise control, lighting, in-car entertainment, for example — will communicate in their own ‘languages’. The signals are then translated into universal CAN protocol for the main onboard computer, which communicates information to the occupants or other elements of the vehicle. 

“When we undid the [G6], everything was so easy to undo with clips … instead of having 10 modules, they’ll have one module that does all of the left-hand side, one module does all the right-hand side and they’re in easy positions to get to.

“Because the whole car runs on [the] CAN Bus system, it can communicate in micro seconds. That's why the whole thing is dedicated to autonomous driving, to have [fast] reaction times,” said Morcos.  

“They've designed this whole system — I reckon they spent more time designing this part of the system than the actual body — they pieced it all together and you can see how delicately they put it for diagnosis, and how everything reacts to each other module and it's very simple to diagnose what the problem is, that's what we found out.”

With CAN Bus, instead of a ‘rats nest’ of different, heavy cables, the bulk of the wiring harness can be simplified into two wires — one there, one back. It’s lighter, simpler and should be faster.

“This whole car, from 4G to the blinker system, no matter what it is in the car, it all works on their CAN Bus system, and it's and it's very responsive,” added Morcos. 

Tesla is also pushing forward with elegant solutions for in-car electronics, with boss Elon Musk allegedly sending a ‘how-to design a 48-volt architecture’ pamphlet to major manufacturers, including Ford. Its Cybertruck uses 48-volt electronics everywhere, allowing its steer-by-wire system. 

The G6 promises rapid processing speeds with a Qualcomm Snapdragon 8155 chip powering the 15-inch touchscreen and, while the phrase ‘software defined vehicle’ makes everyone in the CarsGuide office groan, it is the future of electric cars. 

It drives more than the multimedia system too, in theory making the whole experience more seamless. 

“I've had Tesla technicians come into our car in Melbourne — to spy on us — and they came in and said, ‘man, the refresh rate, processing speed and the quality, it's far superior than ours’,” said Morcos, showing signs of promise for the new G6.

Of course, this all comes with one big caveat: We’re yet to drive the G6, or any of Xpeng’s products, in Australia. They could have annoying driver aids, a poor ride, or clunky multimedia systems. Or not. Either way, we’ll have an answer early next year. 

Unlike Polestar and some European marques, such as Renault, Xpeng does not openly discuss its battery pack’s constituents. The brand does sell vehicles in the EU, which requires battery passports for all vehicles from 2027. 

Speaking to TrueEV CEO Jason Clarke, it is clear that Xpeng’s target is fixed on the back of Tesla. The importer aims to make Xpeng one of the top-five electric vehicle brands in Australia. 

The first model to launch is the Xpeng G6, which is on-sale now in two trim levels with a Performance grade to join next year, followed by the X9 people mover. In the near future, expect a larger G9 SUV and a sporty sedan, known as the P7.
