XPENG G6 vs Tesla Model Y: a technology comparison of the electric SUV with the most advanced driver assistance

The mid-size electric SUV segment is going through a second revolution. If the Tesla Model Y set the standard for years as the best-selling electric vehicle worldwide, the arrival of the XPENG G6 in Spain is reshaping the conversation: 800V architecture, vision-only driver assistance and a technology approach that directly rivals Fremont’s flagship. We put them side by side with data, not slogans.

Two philosophies, one segment

Both cars target the same buyer: tech-savvy families looking for an efficient electric SUV, with updatable software and real capability for travelling across Europe. But the approaches differ. Tesla has spent more than a decade refining vertical integration—software, motor, charging network—while XPENG arrives having learned from others: it bets on cutting-edge starting hardware (800V, next-generation chips) and a conservative design that avoids visual debate.

XPENG G6 from ≈42,800 €: the newcomer with 800V architecture

The XPENG G6 Standard Range features a rear-wheel-drive motor producing 190 kW (250 CV), powered by a 68.5 kWh battery that is homologated for roughly 480 km WLTP. The key figure, however, is not the gross range but the electrical architecture: 800 volts allow it to accept fast-charging peaks notably higher than the segment average, cutting times at high-power chargers.

The G6 also stands out for its SEPA 2.0 platform, a minimalist cabin with dual screens and the XNGP driver assistance system, one of the most ambitious among electric cars available in Spain today.

Tesla Model Y from ≈40,000 €: the global benchmark

The Tesla Model Y RWD offers 220 kW (299 CV), a 64 kWh battery and a homologated range of over 530 km, with a top speed limited to 200 km/h. Its great strength remains the ecosystem: Supercharger, mature software and energy efficiency that, kWh for kWh, is hard to beat.

Driver assistance: XNGP vs Autopilot

This is where the truly differentiating battle takes place. Tesla’s Autopilot is a refined system, with reliable lane reading, adaptive control and assisted lane change (depending on the package). The G6’s XNGP, meanwhile, integrates a broader sensor suite—high-resolution cameras plus radar—and relies on neural networks trained specifically for complex European scenarios. On motorways, both offer a remarkable experience; on secondary roads and in the city, XPENG opts for more proactive assistance, although the homologation of advanced functions depends on current European regulations.

Electrical architecture and charging: 800V as an argument

The G6’s 800V platform allows, at compatible chargers, a theoretical 10-80% recovery in about 20 minutes. The Model Y, on a 400V architecture, doesn’t reach that peak speed but compensates with the Supercharger network, dense and reliable across the Iberian Peninsula. It is the classic dilemma: peak power versus a guaranteed ecosystem.

Real efficiency and range

On paper, the Model Y offers a little over 50 km more than the G6 with a smaller battery. In practice: better energy efficiency from Tesla, which is noticeable on long journeys and at motorway speeds. The XPENG, however, offers greater gross battery capacity, which may work in its favour in cold climates or with intensive climate-control use.

Technology value per euro

The prices listed are the manufacturer’s recommended RRP, not counting offers, dealer discounts, one-off campaigns or Plan MOVES aid. With that caveat:

• Tesla Model Y: from ≈40,000 €. More range, more efficiency, own network.
• XPENG G6: from ≈42,800 €. 800V architecture, XNGP, more complete standard equipment.

Summary table and score

Highmotor verdict

The Tesla Model Y remains the gold standard for efficiency, range and charging ecosystem. The XPENG G6 is the technologically better-equipped challenger: 800V, XNGP and generous equipment make it a serious alternative for those who prioritise cutting-edge hardware over a proprietary network.

Frequently asked questions

Which has more real-world range, the XPENG G6 or the Tesla Model Y?
In WLTP homologation, the Tesla Model Y RWD claims a little over 530 km versus the 480 km of the XPENG G6 Standard Range. In real consumption, the Model Y’s efficiency is also usually slightly better.

What advantage does the XPENG G6’s 800V architecture bring?
It allows higher fast-charging peaks, reducing charging time at compatible high-power chargers compared with the Model Y’s 400V.

Is XNGP or Autopilot better in Spain?
Both are advanced Level 2 systems. Autopilot stands out for maturity and reliability; XNGP, for more complete hardware and functional ambition, although its rollout in Europe depends on specific approvals.

Which electric SUV offers the better price-technology ratio in 2026?
The Tesla Model Y starts at a lower indicative price with a better charging network, while the XPENG G6 offers more standard technology equipment for about 2,800 € extra. The choice depends on whether you prioritise ecosystem or hardware.
