On the evening of July 28, SAIC Volkswagen promoted through official channels that its ID. ERA 9X model is equipped with the EA211 range extender, highlighting that this range extender supports 92-octane, 95-octane, and 98-octane gasoline. This announcement came shortly after Xiaomi revealed on the same day (July 28) that its "Kunlun Range Extender" also supports the same fuel grades, sparking online discussions. According to comparative information, both Xiaomi’s Kunlun Range Extender and Volkswagen’s EA211 support all three gasoline octane ratings. In terms of warranty coverage, Xiaomi offers an 8-year or 160,000-kilometer warranty for the range extender and the entire tri-motor electric system (battery, motor, and power electronics). SAIC Volkswagen goes further by additionally providing a lifetime warranty for the entire vehicle. Under WLTC driving conditions, the lowest fuel consumption in low-battery mode is 5.7 L/100 km for Xiaomi’s Pengcheng series, compared to 6.27 L/100 km for the ID. ERA 9X. Regarding maintenance intervals, Xiaomi states that after the initial service, subsequent maintenance is required every three years or every 30,000 kilometers driven by the range extender; Volkswagen has not specified exact maintenance intervals. Technically, the EA211 range extender is based on the 1.5T EVO II engine and features VTG (Variable Turbine Geometry) turbocharging technology. In terms of battery and range, Xiaomi’s Pengcheng series offers a maximum battery capacity of 76 kWh, delivering up to 505 km of CLTC-rated all-electric range. The mid- and high-trim variants of the ID. ERA 9X are equipped with a 65.2 kWh CATL battery pack, offering a CLTC all-electric range of 406 km. Xiaomi plans to unveil its "Kunlun Technology Architecture" on the evening of July 30, alongside the launch of two new models: the large seven-seat flagship extended-range SUV Pengcheng N90 Max and the large five-seat all-wheel-drive extended-range SUV Pengcheng N70 Max.
