Xiaomi has launched Pengcheng, a four-model extended-range series built on a new platform architecture codenamed Kunlun, a program the company spent roughly three and a half years developing separately from the SU7. The line-up pairs a large five-seat N70 (Pro at 209,900 yuan, Max at 239,900 yuan) with a seven-seat N90 (Max at 269,900 yuan, Explorer edition at 299,900 yuan), with both Max trims undercutting their pre-sale prices and launch perks worth 43,000 to 81,000 yuan depending on the version.
The design logic treats the car as a dwelling. The N70 flattens the floor and buries five sliding rails so the second row can travel more than 1.4 metres; the N90 Explorer adds 1.7 square metres of wood flooring with three-level floor heating up to 38°C, rotating seats, a bed that sets up in 30 seconds and a pop-up roof giving 2.29 metres of standing height. Lei Jun also stressed running costs: 92-octane fuel, 5.7 L/100 km with a depleted battery, servicing every three years or 30,000 km after the first visit, and a fridge drawing under 1 kWh a day.
The launch lands in a shrinking market — August 2026 passenger-car retail fell to 1.626 million units, nearly 20% down year on year, with the EREV segment also contracting — and Lei Jun admitted costs ruled out a standard version below 200,000 yuan. At 5.28 metres long with a 3,080 mm wheelbase, the N90 Max undercuts rivals like the new Lixiang L9 (from 459,800 yuan) and the AITO M9 EREV (from 479,800 yuan) because Xiaomi shifted budget away from flagship hardware toward features used while parked.
Much of the event was devoted to self-verification: a nail-penetration test at full charge and 55°C after bottom collision and wading, a 14-tonne roof-crush figure with a VP standing on the roof, and a re-run of the N90 Max's 1,230 km Shanghai–Beijing range drive to dispel a downhill-route complaint, plus a claim of using the most expensive driver-assistance chip available. The piece frames Pengcheng as Xiaomi wagering that once a car feels like a place to linger, people will move time normally spent at home into a parked vehicle.
