NAF and the magazine Motor ran the summer edition of El Prix over two days in Oslo in June 2023 with 32 electric cars. XPENG’s G9 covered 588 km, the P7 557 km. XPENG prints these as 113 per cent and 110.3 per cent of WLTP, meaning both went further than their stated WLTP ranges. Neither car’s WLTP figure appears in the release.
The weather was good and the test ran in optimal summer conditions; XPENG says so itself. Only about a third of the 32 cars beat their WLTP figure. The tested G9 was the Long Range four-wheel-drive Performance version with the 3C battery, which NAF lists at 520 km WLTP with a 93.1 kWh net battery. The 588 km therefore belongs to the fast version, not to the rear-wheel-drive Long Range, which is listed at 570 km.
The charging
The records here are clean. The G9 peaked at 319 kW, the highest NAF had measured, and averaged 212 kW, also a first in NAF’s history. NAF calculated that the car adds 200 km of range in 8.4 minutes. The car, which the release here calls the P7i, runs on 400 V, used 13.7 kWh per 100 km and peaked at 189 kW.
The G9 and P7 had gone on sale in Norway, Sweden, the Netherlands and Denmark in February that year, and that launch has its own story. Later measurements: the X9 in El Prix 2026 from the same test series, and the G9 that won WK Snelladen in 2026, a Dutch charging test. The XPENG G9 page has the car.
