XPeng Motors (NYSE:XPEV) has completed regulatory filings for its new flagship six-seat SUV, the XPeng GX, and has begun L4 autonomous driving tests on public roads in Guangzhou.

The GX is XPeng’s first large, three-row flagship SUV and is scheduled for launch in April–May 2026, CEO He Xiaopeng said. The model has entered open-road L4 testing with vehicles marked “L4 autonomous driving test” and “please keep clear,” indicating the start of large-scale validation in real urban traffic.

The vehicle has been filed with regulators in six variants, including three extended-range electric vehicle (EREV) versions and three battery electric vehicle (BEV) versions. All versions list XPeng’s Guangzhou factory as the production site.

The GX measures 5,265 mm in length, 1,999 mm in width, and 1,800 mm in height, with a wheelbase of 3,115 mm. The size places it squarely in China’s large three-row SUV segment, competing with 9-series models from AITO, NIO, Zeekr, Li Auto.

XPeng has positioned the GX as a flagship focused on third-row usability and full six-seat comfort. The long wheelbase and long rear overhang are intended to preserve usable cargo space even when all three rows are occupied, addressing a common limitation in large SUVs.

Extended-range versions are powered by a 1.5-liter range-extender engine producing 110 kW. The EREV models use a dual-motor electric drivetrain with outputs listed at 210 kW and 160 kW, depending on configuration.

Curb weight is listed at 2,840 kg or 2,890 kg, and top speed is 200 km/h (124 mph). MIIT filings list a pure-electric driving range of 320 km (199 miles) for the EREV variants. The battery uses lithium iron phosphate chemistry supplied by CALB.

Battery electric versions are offered in rear-wheel-drive and all-wheel-drive configurations. The rear-wheel-drive version uses a single 270 kW rear motor. The all-wheel-drive version adds a 160 kW front motor while retaining the 270 kW rear motor.

Curb weights for BEV variants are listed at 2,690 kg, 2,750 kg, 2,785 kg, and 2,820 kg. Top speed is also listed at 200 km/h (124 mph). Battery options include lithium iron phosphate and ternary lithium chemistries.

The GX is built on XPeng’s SEPA 3.0 physical AI vehicle architecture. The model is equipped with steer-by-wire and rear-wheel steering, features intended to improve maneuverability and stability in a vehicle of this size. XPeng has said the chassis system integrates AI-based coordination to address handling limitations typically associated with large three-row SUVs.

Autonomous driving hardware includes four self-developed Turing AI chips, providing 3,000 TOPS of effective on-device computing power. XPeng has stated that the GX supports L4 autonomous driving capability within defined operational areas.

The open-road testing program in Guangzhou is designed to validate perception, decision-making, and control in complex urban environments. The test scope includes intersections, pedestrian avoidance, lane changes, overtaking, and pull-over and parking scenarios. XPeng has not disclosed the geographic limits or commercial rollout timeline for L4 functions.

The GX follows a year of strong growth for XPeng. The company delivered 429,445 vehicles in 2025, up 125.94% year over year. XPeng has set a 2026 sales target of 550,000 to 600,000 vehicles, implying growth of about 28% to 40%.

January 2026 deliveries declined to 20,011 units, down 34.07% year over year and down 46.65% from December 2025, underscoring the importance of new model introductions to sustain delivery momentum.

Pricing, final trims, and detailed configuration information for the GX have not yet been announced. XPeng has also not confirmed whether L4 functionality will be available at launch or enabled through later updates.

As multiple flagship SUVs are scheduled to launch in the second quarter of 2026, the GX will test whether XPeng’s combination of large-vehicle packaging and advanced autonomous hardware can translate into sustained demand in an increasingly crowded and cutthroat premium large SUV segment.
