Kia EV3
XPENG G6
The XPENG G6 costs £6,935 more than the Kia EV3. For that premium it adds 255 kW faster peak rapid charging, 111 litres more boot space and 68 kW more power. The Kia EV3 is not just cheaper - it also offers lower energy use, 149 versus 175 Wh/km. On EVcarsguide's combined category scores, the XPENG G6 comes out ahead overall.
The Kia EV3 is £6,935 cheaper to buy. The Kia EV3 is cheaper to charge, roughly £160 a year versus £192 for the XPENG G6, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Kia EV3 comes out roughly £7,095 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
EVcarsguide estimates a real-world motorway range of about 193 miles for the Kia EV3 and 193 miles for the XPENG G6 - effectively matched, and both well below their WLTP figures because sustained high speed is the hardest case for an EV. A rapid charge to 80% takes around 29 minutes in the Kia EV3 and 12 in the XPENG G6, so the XPENG G6 loses less time at each stop.
The Kia EV3 is the easier car for tight UK car parks: it is 70 mm narrower than the XPENG G6. In a standard 2,400 mm bay that leaves about 550 mm of total clearance for the Kia EV3 and about 480 mm of total clearance for the XPENG G6. The Kia EV3 also turns in a 1.2 m tighter circle, which helps with U-turns and multi-storey ramps.
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 89% battery health for the Kia EV3 and 90% for the XPENG G6. That is close enough that capacity loss should not decide between them. The XPENG G6's LFP-type pack tolerates daily 100% charging, while the Kia EV3's NMC-type pack lasts longest kept to about 80% for everyday use. Both batteries carry a 8-year manufacturer warranty.
