The Mengshi M800 is a full-size extended-range electric SUV developed by Dongfeng Motor Corporation’s off-road brand, MHERO. Positioned as the flagship "new off-road species", it represents the brand's key contender in the ultra-luxury electric off-road segment. Officially launched in September 2024, the model is available in two variants—Standard Roof and High Roof—with official guide prices of RM879,000 and RM979,000, respectively. Regarded as a high-end bespoke edition of the Mengshi 917, the M800 builds upon its robust military DNA and hardcore off-road capability, elevating its market standing through a larger body profile and an enhanced suite of luxury amenities.
Positioned as a full-size extended-range electric SUV, the Mengshi M800 measures 5,136 mm in length, 2,172 mm in width, and 2,063 mm in height, with a 2,950 mm wheelbase. Featuring a 5-door, 5-seater layout, the SUV records a substantial kerb weight of 3,270 kg. Key highlights include a tri-motor all-wheel-drive system (600 kW / 1,050 Nm), front and rear double-wishbone independent suspension, a ladder-frame chassis, front and rear differential locks, rear-wheel steer-by-wire, and a state-of-the-art smart luxury cockpit. It primarily rivals flagship luxury off-roaders such as the Yangwang U8 and Tank 700 Hi4-T. As a bespoke model, the M800 comes standard with exclusive exterior features, including the "Interstellar Chariot" widebody kit, a carbon-fibre bonnet, bespoke badging, a carbon-fibre high roof, and a tailgate-mounted carbon-fibre storage box ("small backpack").
The Mengshi M800 adopts a bold "mecha-inspired" design language, giving the exterior an exceptionally imposing road presence. Up front, the raised bonnet lines combine with sharp, sculpted creases to project the commanding look of a "mobile fortress". The front fascia features a trapezoidal grille flanked by cross-shaped LED daytime running lights, ensuring instant recognisability at night. The rugged front bumper is integrated into the standard "Interstellar Chariot" bodykit, further amplifying the vehicle's aggressive, battle-ready stance.
In profile, flared wheel arches contrast with an upright windscreen, accentuating its authentic hardcore off-roader proportions. A taut, horizontal beltline is complemented by 20-inch all-terrain tyres, delivering a planted and sturdy stance. At the rear, the cross-shaped tail lights and external tailgate-mounted storage box serve as signature Mengshi design cues. The rear bumper mirrors the rugged styling of the front fascia for a cohesive, muscular appearance. The exterior palette offers distinctive matte metallic finishes, including Aden Grey and Fanjing Green, underscoring its premium positioning.
Inside, the Mengshi M800 retains the dashboard architecture of the Mengshi 917. The centre console is anchored by a dual-screen setup comprising a 15.6-inch floating central touchscreen and a 12.3-inch digital instrument cluster. This is complemented by a 12.3-inch front passenger entertainment display and an 8.0-inch rear multi-function touchscreen, creating a comprehensive four-screen interactive cockpit. Interior upholstery options include Obsidian Black, Interstellar Grey, and an Hermes Orange/Morandi Green two-tone combination. The centre console, door grab handles, and gear shifter surround feature extensive carbon-fibre trim inserts, which, along with plush leather seats and a Dynaudio premium sound system, inject high levels of luxury into its utilitarian character.
The Mengshi M800 is driven by a range-extended electric vehicle (REEV) powertrain comprising a 1.5-litre turbocharged four-cylinder range extender and three electric drive motors. The internal combustion range extender (engine code DFMC15TP1) produces a maximum output of 145 kW (around 197 PS), runs on minimum RON 92 petrol, and complies with China VI emission standards. The tri-motor setup (one front motor, two rear motors) delivers a combined system output of 600 kW (approx. 816 PS) and an immense peak torque of 1,050 Nm. Power is channelled through a 2-speed automatic transmission (AT), propelling this 3.3-tonne full-size SUV from 0 to 100 km/h in an impressive 6.76 seconds.
Energy is stored in a 65.8 kWh CATL-supplied ternary lithium battery pack, providing a CLTC pure electric range of 125 km and a CLTC combined range of up to 750 km. When hooked up to a DC fast charger, recharging the battery from 30% to 80% takes approximately 37 minutes. Under the WLTC test cycle, combined fuel consumption is rated at 2.36 L/100 km, supported by an 84-litre fuel tank. The vehicle also features 6 kW Vehicle-to-Load (V2L) external power output capabilities, ideal for powering campsite equipment and electronic appliances.
The Mengshi M800 is built on a heavy-duty ladder-frame chassis (body-on-frame construction), providing the torsional rigidity required to withstand severe structural stress during extreme off-road driving. The suspension incorporates front and rear double-wishbone independent setups—a premium configuration for a dedicated off-roader that delivers generous wheel articulation off-road while maintaining composed on-road ride comfort.
The chassis features adaptive air suspension with active damping and height adjustment across a 150 mm range, allowing ground clearance to be varied from 221 mm to 326 mm. Off-road credentials include an approach angle of 24°, a departure angle of 30°, a ramp breakover angle of 22.6°, a maximum wading depth of 850 mm, and a maximum climbing gradient of 100% (45°), placing it among the most capable production SUVs available.
Traction is managed by an electric all-wheel-drive system equipped with front and rear electronically controlled differential locks alongside a centre differential locking function. This is paired with the Mengshi All-Terrain System, VMC vehicle dynamics control, wading depth sensors, crawl control, and crab-walk mode. The rear-wheel steer-by-wire system allows up to ±10.27° of steering angle, trimming the turning radius down to just 5.1 metres—greatly improving agility during tight urban U-turns and narrow trail navigation for a vehicle exceeding 5.1 metres in length.
The Mengshi M800 runs on the M-Link smart cockpit architecture powered by the Qualcomm Snapdragon 8195 processing chipset. The cabin displays include a 12.3-inch digital instrument cluster, a 15.6-inch floating central touchscreen, a 12.3-inch front passenger display, and an 8.0-inch rear control screen. The system supports 5G connectivity, over-the-air (OTA) remote updates, and integrated navigation. The voice command system is activated with the prompt "Hello, Mengshi" to control multimedia, navigation, telephony, and climate settings.
Standard comfort and convenience equipment across the range includes:

Serving as the halo product driving MHERO's upmarket push, the Mengshi M800's positioning and price point place it firmly in the ultra-luxury electric off-road segment. Industry observers view the M800 as a bespoke, coachbuilt iteration of the Mengshi 917, featuring upgraded dimensions, elevated specifications, and higher customization. While its bold design places it in a niche without direct styling clones, it contends in the same competitive space as the Yangwang U8 and Tank 700 Hi4-T.
Early market reception highlights the vehicle's successful blending of hardcore trail capability with executive-grade cabin luxury. Reviewers point out three main strengths: first, authentic off-road engineering stemming from its military pedigree—featuring front and rear double-wishbone suspension, triple differential locks, crab-walk steering, and an 850 mm wading capacity; second, robust performance from its tri-motor hybrid powertrain, delivering a 0-100 km/h sprint of 6.76 seconds despite its 3.3-tonne heft; third, the pairing of an aggressive mecha exterior with an opulent multi-screen cabin, catering to both urban executive presence and rugged off-grid touring.
Nonetheless, the M800 encounters notable market hurdles. An entry price starting from RM879,000 confines it to an exclusive high-end segment where brand equity is still building relative to established luxury rivals. Secondly, while its 125 km EV range and 750 km combined range cover standard driving duties, long-distance overland expeditions rely heavily on the petrol range extender, meaning fuel efficiency and power delivery under low battery states-of-charge remain key considerations for cross-country drivers. Finally, with an overall width exceeding 2.1 metres and length past 5.1 metres, navigating narrow city streets and multi-storey car parks requires careful driver attention.
The Mengshi M800 stands as the flagship symbol of Dongfeng MHERO's evolution from a dedicated military vehicle builder into an ultra-luxury electric off-road brand. Fusing military-grade structural engineering with mecha-inspired styling and a potent tri-motor range-extender system, it establishes a distinct "hardcore luxury" identity. Positioned above the standard Mengshi 917, the M800 sets a new brand benchmark in physical footprint, feature content, and bespoke customisation.
In terms of overall product capability, the M800 demonstrates strong fundamentals across straight-line performance (600 kW / 1,050 Nm, 0-100 km/h in 6.76s), terrain competence (triple locks, crab-walk mode, 850 mm wading depth), and cabin refinement (quad-screen interface, Dynaudio sound system, rear massage seating). With the high-end off-road market becoming increasingly competitive, the M800's long-term standing against competitors like the Yangwang U8 will hinge on sustained brand building, client experience, and aftersales network support.
For high-net-worth buyers seeking uncompromising off-road capability, striking design, and executive road presence, the Mengshi M800 presents a compelling proposition. The choice between the Standard Roof (RM879,000) and High Roof (RM979,000) variants comes down to roof profile and bespoke kit—with the High Roof model offering enhanced rear headroom alongside exclusive carbon-fibre aerodynamic packages for those demanding the ultimate specification.
