800V architecture changes the game on long-distance routes: the Hyundai Ioniq 6 AWD charges 10-80% in just 18 minutes, while the Porsche Taycan 4S still delivers over 225 kW at 80% state of charge - meaning one fewer stop on a Hamburg to Munich run than any 400V competitor. Analysis based on ADAC 2025, Bjørn Nyland and ev-database.org test data.

Comparison table - charging specifications
| Model | Battery | DC max | 10-80% | WLTP range | Price from (DE) |
|---|---|---|---|---|---|
| Hyundai Ioniq 6 LR AWD | 84 kWh | 320 kW | ~18 min | 614 km | ~52,000 EUR |
| Xpeng G6 RWD LR | 87.5 kWh | 280 kW | ~21 min | 570 km | 39,900 EUR |
| Kia EV6 GT AWD | 84 kWh | 260 kW | ~18 min | 520 km | ~55,000 EUR |
| Porsche Taycan 4S | ~97 kWh | 270 kW | ~23 min | 598 km | ~99,000 EUR |
All four models use 800V architecture, enabling peak charging rates unavailable to 400V platforms. The Ioniq 6 AWD sets a consumer-segment peak power record - 320 kW as measured by ADAC in 2025. The EV6 GT on the same E-GMP platform achieves a similar 10-80% time but at lower peak power, because its battery is slightly smaller. The Taycan finishes slowest in absolute time, but its curve is the flattest - a critical advantage on multi-leg long-distance journeys.

Charging curve analysis - model by model
Hyundai Ioniq 6 LR AWD - peak power record holder
The Ioniq 6 AWD curve starts at 305 kW at 5% SoC and stays above 280 kW through roughly 45%. After that it drops steeply - at 80% only 180 kW remain. This means every minute of charging up to 60-70% SoC is exceptionally efficient, but topping up above 80% is a slower tail phase. Optimal strategy: charge to 70-75%, not to 80%, if time on route is the priority.
Xpeng G6 RWD LR - sustained high power to 70% SoC
The G6 has an unusually flat curve to 70% SoC - the spread between 5% and 65% is only 22 kW (272 vs 250 kW). This stability comes from Xpeng's SEPA platform thermal management. At 80% power drops to 180 kW and the tail phase mirrors the Ioniq 6. Price-wise the G6 offers the best charging speed per euro of purchase price in this comparison.
Kia EV6 GT AWD - same E-GMP platform, slightly lower peak
EV6 GT and Ioniq 6 AWD share the E-GMP platform and 800V architecture, so their curves are similar. EV6 GT has a lower peak (260 vs 320 kW) mainly due to different BMS software settings and segment positioning - the GT targets sportiness over charging efficiency. The 10-80% time is close to the Ioniq 6 because the 84 kWh battery charges proportionally faster.
Porsche Taycan 4S - long-distance master, not a peak power champion
The Taycan's distinction: at 80% SoC it still accepts 225 kW - more than the peak of many 400V cars. This means Taycan drivers can practically charge to 85-90% without heavy time penalty, which is not viable in an Ioniq 6 or G6 (their power at 85% drops below 100 kW). The flat curve comes from sophisticated thermal management - the Taycan keeps battery temperature in a narrow 25-40°C window even during multiple rapid charging sessions.
Real-world route test: Hamburg - Munich (775 km)
Hamburg to Munich is the standard German EV benchmark at 775 km. We assume highway consumption 20% above WLTP at 130 km/h. Departure at 80% SoC, charging to 80% each stop.
| Model | Real range (highway) | Stops | Total charging time | Total trip time |
|---|---|---|---|---|
| Ioniq 6 LR AWD | ~500 km | 1 | ~35 min | ~7 h 15 min |
| Xpeng G6 RWD LR | ~510 km | 1 | ~38 min | ~7 h 18 min |
| Kia EV6 GT AWD | ~470 km | 1 | ~36 min | ~7 h 16 min |
| Porsche Taycan 4S | ~560 km | 1 | ~25 min | ~7 h 05 min |
The Taycan 4S needs one stop on the Hamburg-Munich route but charges fastest thanks to sustained power above 80% SoC, finishing in roughly 7h 05min total including a 25-minute charging stop. The Ioniq 6, G6 and EV6 all complete the journey with a single stop and arrive within 10-15 minutes of each other. Compare this to a typical 400V EV (200 kW peak) needing 50-60 minutes for the same SoC gain.
Business context - charging time is employee time
For companies leasing EVs for sales staff or field consultants, charging time has a measurable cost. At a fully-loaded employee cost of €50/h, 20 minutes saved per charging stop equals €16.70. At 100 long-distance trips annually that is €1,670 in recovered productivity - relevant when comparing lease rates for a fleet of 10+ vehicles. 800V platforms also unlock 350 kW HPC chargers on the Ionity and Fastned networks, now available at most motorway junctions on A1, A7, A9, A95 across Germany.
Summary - which model to choose?
Ioniq 6 LR AWD is the pick for drivers who want the fastest consumer-segment charging at a reasonable ~€52,000. Ideal for those making 2-4 long-distance trips per month. Xpeng G6 offers near-identical charging capability at €39,900 - the best charging speed per euro spent. EV6 GT suits those who want a sportier character alongside fast charging. Taycan 4S wins on routes above 500 km thanks to its uniquely flat curve and range - but at three times the G6 price it is a premium play.
