Time seems to be running differently in the Chinese car industry than elsewhere in the world, and they have offered a very competitive mix of luxury and (over)performance on four wheels. I tested the thoroughly updated Xpeng G9 in its most prestigious and powerful Performance version.<\/p>\n\n\n\n Its exterior silhouette remains elegant, aerodynamic and respectfully huge, measuring almost 4.9 meters in length. I have two parking spaces in my block of flats, and when I parked it next to the family car, it took some skill to get out if I wanted to get into both cars comfortably. Yes, the Xpeng G9 is a concrete family SUV.<\/p>\n\n\n\n But the real revolution happened where the eye can't see, that is, under the sheet metal. Xpeng took a bold step in its most expensive models and switched from NMC battery cells to more advanced LFP (lithium iron phosphate) chemistry. LFP cells have traditionally been considered more resistant and cost-effective, but less energy-dense. In a year and a half, Xpeng has made such progress in cell integration that the new battery has almost identical net capacity as before - 92.2 kWh to be exact.<\/p>\n\n\n\n![\"\"](\"\/wp-content\/uploads\/2026\/05\/PXL_20260516_113839292-scaled.jpg\")
