505 km is a Chinese-cycle claim, not a 505 km holiday-trip promise
Xiaomi founder Lei Jun presented the Skynomad N70 Max on 30 July as the production range-extended electric vehicle (EREV) with the world’s longest pure-electric range. According to the published Chinese specifications, the N70 Max combines a 76 kWh NMC battery with a claimed 505 km CLTC electric range.
It is important to separate the vehicle’s architecture from a conventional plug-in hybrid. The N70 is a serial PHEV, usually called an EREV: its 1.5-litre petrol engine acts as a range extender, generating electricity rather than mechanically driving the wheels. In daily use with a charged battery, it should therefore feel much closer to an EV than to a parallel PHEV.
The figure worth examining is consumption. Dividing 76 kWh by 505 km gives 15.05 kWh/100 km. Xiaomi separately quotes energy consumption as low as 15.85 kWh/100 km under CLTC. The small difference is unsurprising: usable battery capacity, the test procedure and rounding can all affect the published figures.
Still, neither number should be read as a European real-world range result. China’s CLTC cycle is generally gentler than WLTP, especially at higher speeds. A five-metre SUV travelling at 120–130 km/h, in cold weather or fully loaded with family luggage, will not reproduce a 15 kWh/100 km result. Before treating the N70 as a 500 km electric SUV, prospective buyers should run their own consumption assumptions through our EV range calculator.
What the numbers say about the N70 and N90
The N70 measures 4,960 mm long, 1,998 mm wide and 1,785 mm high, on a 2,950 mm wheelbase. It is not a compact crossover wearing an oversized battery. The Max uses two electric motors—210 kW at the front and 100 kW at the rear—for a combined peak output of 310 kW (416 hp).
Xiaomi’s larger Skynomad N90 Max uses the same 76 kWh NMC pack but claims 464 km CLTC. That equates to 16.38 kWh/100 km—around 8.8% more energy per kilometre than the N70 on the simple battery-capacity calculation. Given that the N90 is 5,285 mm long, has a 3,080 mm wheelbase and accommodates seven occupants in a 2+2+3 layout, the penalty is not alarming.
The N90’s charging claim deserves a little arithmetic too. Xiaomi says 20–80% takes 18 minutes. On a 76 kWh pack, that is 45.6 kWh added, equivalent to an average charging power of roughly 152 kW. The company also claims 285 km of range added in 15 minutes; using its own 464 km CLTC total, that implies approximately 46.7 kWh and a theoretical average near 187 kW. These are respectable figures, but they are claims from a launch presentation, not an independently measured charging curve. Peak power is the easy part of a press release; sustained power between 10% and 80% is what determines a family stop.
A smaller battery than Leapmotor, but more claimed range
Xiaomi’s presentation did not name its comparison cars, although one is fairly clear. The Leapmotor D19 EREV has an 80.3 kWh battery and a claimed 500 km CLTC EV range. The Skynomad N70’s headline advantage is therefore only 5 km, despite carrying 4.3 kWh less nominal battery capacity.
There is a relevant packaging difference. The D19 is 5,252 mm long with a 3,110 mm wheelbase, versus 4,960 mm and 2,950 mm for the Xiaomi. A smaller frontal area and lower mass can plausibly help the N70, but a 5 km victory on CLTC does not yet establish a meaningful real-world advantage. This is exactly why independently repeatable range testing matters more than a leaderboard assembled from different official cycles.
Xiaomi says its silicon-carbide electronics, thermal management, low-rolling-resistance tyres and lightweight construction help achieve the result. Those are credible engineering routes to lower consumption. The missing data are kerb weight, usable battery capacity, DC charging curve and results at sustained motorway speeds.
The petrol generator is efficient, but still changes the cost equation
Xiaomi claims more than 44% peak thermal efficiency for the 1.5-litre generator and says it can produce around 4 kWh of electricity from one litre of petrol. At the stated 15.85 kWh/100 km electrical consumption, that corresponds to about 3.96 litres/100 km before allowing for additional drivetrain and operating losses. It is an efficient theoretical result for a large SUV, but it is not equivalent to driving electrically.
For owners, the sensible strategy is simple: charge whenever the car is parked long enough, then treat the engine as long-distance insurance rather than the default energy source. The difference can be calculated using local electricity and petrol prices in our charging cost calculator. Fast-charging availability matters as much as battery size; our European fast-charger database currently tracks 483 Supercharger locations, useful context for drivers comparing an EREV with a battery-electric SUV.
Pre-sale price is aggressive, Europe remains unconfirmed
The N70 Max is listed in China from ¥259,900 in pre-sale, while the larger N90 Max starts at ¥299,900. Xiaomi says lower-positioned variants will follow and that formal launch prices in September will be lower. These are Chinese prices, not European prices: they cannot be converted directly into a Czech, German or UK retail figure once VAT, homologation, logistics and import arrangements enter the calculation.
Nor has Xiaomi confirmed European availability for the Skynomad range. Its battery strategy is nevertheless relevant beyond China, particularly while Chinese manufacturers are moving more production and supply-chain activity towards Europe. We recently examined Gotion’s interest in PowerCo’s Spanish battery factory, and the growing industrial connection is more consequential than any single CLTC range headline.
The Skynomad N70 looks promising on paper: a large NMC pack, strong 310 kW AWD drivetrain and an EREV layout that removes public-charging anxiety. But 505 km is currently a CLTC claim, not a proven real-world record. Xiaomi now needs to publish the full technical data and put the car through independent summer and winter range tests. Until then, the sensible number to remember is 76 kWh—not 505 km.
