GWM's six-seat Tank 700 LWB breaks cover in MIIT filing, setting its sights on the Yangwang U8L

A fresh regulatory filing with China's Ministry of Industry and Information Technology has pulled the covers off GWM's Tank 700 Long-Wheelbase Edition. Stretched 340 mm beyond the standard five-seater to 5,445 mm, with a 3,150 mm wheelbase, the SUV moves to a 2+2+2 cabin built around second-row captain's chairs. It tips the scales at 3,396–3,480 kg and is certified to tow 2,500 kg with a braked trailer.

GWM's paperwork lists two drivetrains. The Hi4-Z plug-in hybrid mates a 185 kW 2.0-litre turbo four to a dual-motor system and a 59.05 kWh Svolt battery, yielding 190 km of WLTC electric range. A 265 kW twin-turbo 3.0 V6 appears alongside it, though its battery and range figures were absent from the initial filing. Styling stays squared-off, with a side-hinged tailgate, enclosed spare wheel and 20- or 22-inch wheels; some cars will carry an optional “GF” tailgate badge whose meaning GWM has yet to explain — the same emblem is offered on a standard-wheelbase 3.0T car in the same filing.

The six-seater effectively picks up where the Tank 800 left off, a luxury flagship concept shown in Shanghai in 2021 that faded from view after mid-2024. It also lands squarely against BYD's Yangwang U8L, which stretches 5,400 mm, seats six and weighs roughly 3,595 kg. The arrival follows cooling demand for the regular Tank 700, whose domestic deliveries eased from 2,628 in May to 2,003 in July. Pricing and an on-sale date remain unannounced.
