BMW iX vs Hyundai IONIQ 5

Side-by-Side Specs

Charging Speed

The Hyundai IONIQ 5 has a peak DC charging speed of 263 kW, which is roughly 78% faster than the BMW iX at 148 kW. In practice, peak speed only tells part of the story. The charging curve, battery temperature, and state of charge all affect how quickly your car actually charges.

The Hyundai IONIQ 5 runs on an 800V architecture, which typically delivers faster and more consistent DC charging throughout the session. The BMW iX uses a 400V platform, which is more common but generally sees steeper charging curve drop-off above 50% state of charge.

For the 10-80% charge (the most common DC fast charging scenario), the Hyundai IONIQ 5 finishes in about 18 minutes, which is 16 minutes quicker than the BMW iX at 34 minutes. On a road trip, that difference adds up over multiple stops.

Range and Efficiency

The Hyundai IONIQ 5 offers 450 km of real-world range, which is 45 km more than the BMW iX at 405 km. These are real-world estimates, not WLTP numbers. Expect your actual range to vary with speed, weather, terrain, and driving style.

Efficiency matters more than battery size for daily driving costs. The Hyundai IONIQ 5 consumes 178 Wh/km, compared to 197 Wh/km for the BMW iX. That means the Hyundai IONIQ 5 uses less energy per kilometer, which translates to lower charging costs and fewer charging stops on longer drives.

A more efficient car does not always mean more range. Battery size plays a role too. The Hyundai IONIQ 5 has a 80 kWh useable battery , while the BMW iX has 71 kWh.

Cold Weather Charging

The BMW iX comes with a heat pump as standard, giving it an advantage in cold weather efficiency. The Hyundai IONIQ 5 does not include a heat pump as standard.

Battery preconditioning is equally important for winter DC fast charging. When the battery is cold, charging speeds drop significantly. Both cars support preconditioning, which warms the battery before you arrive at a fast charger so you get closer to peak charging speed.

In cold conditions, expect 20-35% range loss compared to ideal weather. Cars with both a heat pump and preconditioning typically handle winter better overall.

Which One Should You Choose?

If fast charging speed is your priority, the Hyundai IONIQ 5 has the edge with 263 kW peak DC and a 18-minute 10-80% time. For long road trips with multiple charging stops, that faster turnaround makes a real difference.

If you mostly charge at home or at work and care more about daily driving costs, the Hyundai IONIQ 5 is the more efficient choice at 178 Wh/km. Lower consumption means lower electricity bills over time.

For maximum range between charges, the Hyundai IONIQ 5 gives you 450 km of real-world range, which is 45 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
