XPeng GX Range Revealed: BEV up to 750km, EREV 320km, Hong Kong Awaits He Xiaopeng's "2027 Promise"

The contours of XPeng's flagship SUV are becoming increasingly clear. On March 19, the latest "Catalog of New Energy Vehicle Models Eligible for Vehicle Purchase Tax Exemption" revealed the complete powertrain and range information for the XPeng GX. Positioned as an "AI New Luxury Large Six-Seat Flagship," this full-size SUV will offer both extended-range (EREV) and all-electric (BEV) powertrain options. The BEV version delivers CLTC ranges covering four variants: 635km, 665km, 720km, and 750km. The EREV version is equipped with a 1.5T range extender, offering a pure electric range of 320km and a combined range exceeding 1,200km .

The new model is built on XPeng's new SEPA 3.0 Physical AI vehicle architecture and comes standard with steer-by-wire and rear-wheel active steering systems. It is expected to be officially unveiled at the Beijing Auto Show in April . For Hong Kong users, the arrival of the XPeng GX raises a pertinent question: when this flagship SUV, nicknamed by netizens as the "Greater Bay Area Range Rover," arrives with technological features like steer-by-wire, rear-wheel steering, and 5C ultra-fast charging, could it become a new option for Hong Kong residents driving north for leisure or commuting within the mainland? More importantly, could Chairman He Xiaopeng's "2027 promise" regarding autonomous vehicles entering Hong Kong be realized first with this flagship model?

Dimensions and Design: The Aura of a "Greater Bay Area Range Rover"

The XPeng GX measures 5,265mm in length, 1,999mm in width, and 1,800mm in height, with a substantial wheelbase of 3,115mm . What does this size mean? Compared to rivals like the Li L9 (wheelbase approx. 3,105mm) or the AITO M9 (approx. 3,110mm), the GX firmly enters the full-size luxury SUV segment. Its 3.1-meter wheelbase, combined with a three-row, six-seat layout, ensures ample and comfortable space for every passenger.

Design-wise, the GX has earned the internet nickname "Greater Bay Area Range Rover" for its minimalist yet muscular lines, clamshell hood, split headlights, and floating roof design, which indeed carry hints of British luxury styling . The front features a three-section through-type daytime running light strip, with dual vertical light clusters below. The front bumper integrates an active grille shutter. The rear features through-type taillights with diffuse reflection treatment, complemented by a split tailgate design (upper and lower opening), resulting in a lower trunk sill for easier loading of large items .

The vehicle adopts a long-wheelbase, long-rear-overhang stance, accented with gold trim to enhance the premium feel. Wheel options include 21-inch and 22-inch sizes, with the 22-inch version offering a staggered tire setup for personalization .

Powertrain and Range: Dual Strategy with BEV 750km + EREV 320km

The XPeng GX offers both BEV and EREV powertrain options, precisely addressing the diverse range needs of the current market.

The BEV version utilizes an 800V high-voltage SiC platform, featuring XPeng's self-developed hybrid silicon-carbide coaxial electric drive and supports 5C ultra-fast charging technology. Battery pack options include a 91.9kWh LFP (lithium iron phosphate) and a 110kWh ternary lithium battery, corresponding to CLTC ranges of 635km, 665km, 720km, and 750km . Charging efficiency is impressive, with a 10% to 80% charge taking just 12 minutes, and a 15-minute charge adding 500km of range, effectively addressing range anxiety . In terms power output, the single-motor rear-wheel-drive version produces a maximum power of 270kW, while the dual-motor all-wheel-drive version achieves a combined output of 430kW (approx. 585 hp), enabling 0-100km/h acceleration in the 4-second range .

The EREV version is powered by a 1.5T range extender (110kW) paired with dual electric motors (160kW front, 210kW rear), delivering a combined output of 370kW. It is equipped with a 63.6kWh battery pack, providing a WLTC pure electric range of 320km and a combined range exceeding 1,200km . What does a 320km pure electric range mean? For a Hong Kong user with a 30km daily commute, this means charging just once a week. Even without a home charger, a quick top-up at a shopping mall on the weekend would suffice for the entire week's driving. The range extender only becomes necessary for longer journeys.

Chassis Technology: The Agile Combination of Steer-by-Wire and Rear-Wheel Steering

The XPeng GX comes standard with steer-by-wire and rear-wheel active steering systems, a rare combination in a large SUV . Steer-by-wire eliminates the traditional mechanical connection, resulting in faster response times, stable handling at high speeds, and light maneuverability at low speeds. The rear-wheel steering function significantly reduces the turning radius, giving this vehicle, over 5.2 meters long, the agility comparable to a compact car when making U-turns on narrow roads or navigating tight parking lot curves .

Notably, the XPeng GX will be the world's first production model equipped with Bosch's next-generation steer-by-wire system, which is natively compatible with L4-level autonomous driving and integrates over 100 functions . This also marks the first time L4-level steer-by-wire capability has been mass-produced in a vehicle priced under 500,000 RMB. For users seeking future-proofing for advanced autonomous driving, the value of this hardware pre-installation is significant.

Intelligent Driving: 4 Turing Chips + XNGP 5.0

Intelligence has always been XPeng's strong suit, and the GX continues this legacy. The vehicle is equipped with 4 self-developed Turing chips, providing a local effective computing power of up to 3000 TOPS, with each chip estimated at 700-750 TOPS . This hardware not only supports the current XNGP 5.0 intelligent driving system but also provides ample redundancy for future upgrades to L4-level autonomous driving.

XPeng has already begun real-world technical validation in Guangzhou, supporting "hands-off, feet-off" driving, with the manufacturer clearly assuming liability in such scenarios . Hardware-wise, it features a multi-radar perception suite, enabling high-level assisted driving functions like unprotected left turns and navigating complex roundabouts, as well as cross-floor valet parking with error margins within 5cm. On the software side, it incorporates the second-generation VLA (Vision-Language-Action) large model, reducing system reaction time from 200 milliseconds to 80 milliseconds for more human-like decision-making .

For Hong Kong users, while local regulations currently restrict such advanced driver-assistance systems, having the hardware pre-installed offers future-proofing. As legal frameworks potentially evolve, today's hardware could unlock tomorrow's functionality.

Intelligent Cockpit: Dual 8295 Chips + XOS 5.0

The infotainment system is equally impressive. The GX features dual Qualcomm 8295P chips, delivering 60 TOPS of computing power paired with the XOS 5.0 system for millisecond-level interactive response . The full-scenario voice assistant "Xiao P" supports private interaction via the driver's headrest speakers, allowing effortless control of functions like climate and navigation without manual activation. Features like holographic digital twin and AR navigation further enhance the technological feel .

The interior adopts the "Aura Utopia" design philosophy, featuring premium materials like European G3 curved genuine wood veneers, Nappa leather, and Microfiber suede headliner, exuding luxury both in touch and appearance . The seating layout is 2+2+2, with the official claim that "every seat is a VIP." The second row features airline seats with 180-degree electric rotation, allowing for a "meeting room" configuration facing the third row. The third row also boasts independent headrests, ventilation, heating, and leg rests, finally eliminating the "emergency seat" stigma .

Practicality is also well-considered. With all six seats occupied, the trunk still offers over 480 liters of storage space. Folding the seats down expands this to 2,100 liters, easily accommodating camping gear, strollers, or luggage .

Hong Kong Market Perspective: He Xiaopeng's "2027 Promise" and RHD Imagination

Turning the focus to Hong Kong, the arrival of the XPeng GX is closely linked to the brand's development in the territory. Last March, during the Two Sessions in Beijing, He Xiaopeng, a National People's Congress deputy and Chairman of XPeng, clearly stated that XPeng is developing well in Hong Kong and expressed his hope that the company's autonomous vehicles could enter Hong Kong by 2027 . He revealed that the company plans to skip L3-level autonomous driving and launch production models with L4 capabilities this year, aiming to complete high-definition map upgrades for major cities nationwide within the year to provide real-time data support for vehicles .

As XPeng's flagship model for 2026, the GX, equipped with steer-by-wire, rear-wheel steering, and four Turing chips, is precisely the hardware foundation pre-installed for L4 autonomous driving. If this vehicle can be successfully introduced in a right-hand-drive (RHD) version, it would become the first domestic large SUV in the Hong Kong market with L4-level hardware potential.

From a practical standpoint, the GX's characteristics align well with the needs of Hong Kong residents driving north for leisure. The 3,115mm wheelbase and three-row, six-seat layout handle family transport or business needs with ease. The 750km BEV range means a trip from Hong Kong to Changsha could be completed without recharging. The EREV's 320km pure electric range, combined with a 1,200km total range, completely eliminates long-distance anxiety. The addition of steer-by-wire and rear-wheel steering significantly enhances the practicality of this large SUV on Hong Kong's narrow streets.

Of course, the cost of RHD development versus the market size remains a real challenge. However, as XPeng's sales network in Hong Kong gradually matures and He Xiaopeng's "2027 promise" deadline approaches, the introduction of an RHD GX version is not inconceivable.

Personal Opinion: The Significance of Steer-by-Wire Lies in "Future Usability"

Looking at the revealed information for the XPeng GX, the most striking impression is the product philosophy of "preparing for the future."

The 750km range, 5C ultra-fast charging, and 320km EREV range address current user pain points. However, the steer-by-wire, rear-wheel steering, and four Turing chips are the hardware foundations pre-installed for future L4 autonomous driving. He Xiaopeng's clear intention to "skip L3 and go straight to L4" reflects a forward-looking judgment on the ultimate destination of intelligent driving.

For Hong Kong users, the value of steer-by-wire isn't just in the spec sheet; it's in the direction it represents. As regulations potentially ease and autonomous driving eventually becomes a reality, today's hardware pre-installation will become tomorrow's usable functions. With XPeng's sales network in Hong Kong gradually improving and He Xiaopeng's commitment nearing its target date, the introduction of an RHD GX version might only be a matter of time.

The XPeng GX will be officially unveiled at the Beijing Auto Show in April. For Hong Kong users considering their next vehicle, this is a date worth watching. When the "Greater Bay Area Range Rover" eventually graces Hong Kong's streets, it will represent not just a car, but a new possibility for the era of intelligent driving.
