450 km observed against 445 — effectively identical. The Ioniq 5 charges from 10 to 80 percent in eighteen minutes against the ID.4’s 28. The ID.4 costs £7,905 less in the UK. This is a straight trade of money for time, and how much you drive decides it.

Range: call it a draw
450 km against 445 km observed, from 80 kWh against 77. The ID.4 is fractionally the more efficient at 173 Wh/km against 178. On the EPA cycle the Ioniq 5 leads more clearly, 318 miles against 291; on WLTP they are within two of each other, 570 km against 572.
Three different measurements, three different verdicts, all within a few percent. The honest reading is that these two cars go the same distance.
Charging: ten minutes, every stop
263 kW peak on 800 volts against 175 kW on 400, and eighteen minutes against 28 across the 10-80 percent window. Ten minutes per rapid stop is the single largest difference between these two cars.
Work out what that is worth to you rather than assuming. If you rapid charge twice a month, it is four hours a year. If you rapid charge twice a year, it is forty minutes — against £7,905.
What else separates them
The Ioniq 5 offers 3.6 kW of vehicle-to-load; the ID.4 offers none, and Volkswagen’s announced bidirectional DC is not supported on the car as sold, so we have left that field blank rather than list an announcement as a feature.
The ID.4 is quicker in a straight line — 210 kW and 545 Nm against 168 kW and 350 Nm, 6.7 seconds against 7.5 — which is not the usual direction for a cheaper car in this database.
Which one should you buy
Buy the ID.4 if most of your charging happens at home. You are paying nearly eight thousand pounds less for the same range and losing ten minutes on the rare occasions you rapid charge.
Buy the Ioniq 5 if you do serious distance regularly, or if vehicle-to-load solves a real problem. The 800-volt charging is genuinely better and it is what the extra money buys.
Frequently asked questions
Which goes further, the Ioniq 5 or the ID.4?
They are effectively equal: 450 km against 445 km observed. The EPA cycle favours the Ioniq 5 and WLTP calls it a draw, so no meaningful difference.
How much faster is the Ioniq 5 to charge?
Ten minutes over the 10-80 percent window: eighteen against 28. Its 800-volt architecture holds high power for longer rather than simply peaking higher.
Is the ID.4 worth the saving?
For a home charger, almost certainly. £7,905 in the UK buys a great deal of electricity, and the ten-minute charging penalty only applies when you use a rapid charger.
