Comparison of 2021 VW ID.4 1st Ed and 2020 Hyundai Ioniq EV

The Volkswagen ID.4 is the first all electric crossover SUV that VW made starting in 2021. It is built on the same MEB platform as the ID.3, but is larger. Its advertising claim was a car for the millions, not the millionaires.
The Hyundai Ioniq is a compact hatchback and the flagship EV by Hyundai. The gas versions started limited production as far back as 2010. In addition to its all electric version, it is also available as a hybrid and a plug-in hybrid model. The EV was first produced in 2017 and through 2019 it was the most efficient EV in the US according to the EPA with a rated economy of 136 miles per gallon gas equivalent.
  2021 VW ID.4 1st Ed 2020 Hyundai Ioniq EV 2020 Toyota Camry LE⁵
Approximate Price¹ $45,000 $35,000 $25,000
Useable Battery Size² 77 kWh 30.5 kWh Gastank ~= 479 kWh
Efficiency³ 3 miles/kwh 4.5 miles/kwh Gas ~= 1.1 miles/kwh
Range at 70mph⁴ 231 miles 137 miles 526 miles
¹Prices of electric vehicles are highly volatile and greatly depend on options and dealer charges included. The price show is an estimated price of the comparison vehicle including in the "ChargeDischarge.com" test.
²Manufacturer's often hold back some of the battery capacity to extend the battery life and/or are not forthcoming about the usable battery size.
³Efficiency greatly varies base on many factors. The value here is from testing at 70MPH. See references below.
⁴Similar to efficiency, the range value shown here is just the battery size times the efficiency. This gives an estimated MAX range for a full battery and driving at 70MPH.
⁵The Camry gas tank size of 15.8 gallons and efficiency of 38 miles/gallon has been converted to the battery equivalents.

Comparison Graphs

Each bar in this graph represents the Range Added with 20 Minutes of Charging for different STARTING states of charge (SOC). This 20-minute charge mile rating is a common comparison metric for electric vehicles. It is a measurement of much range can you add with 20 minutes of charging. Even this will be greatly impacted by a variety of factors. A battery pack will charge faster when it is less 'full'.
The charge curve graphs here show for the VW ID.4 and the Hyundai Ioniq are a key part of the ChargeDischarge storyline for these two cars. The faster (more power) you can charge the faster you can add range. But do not forget that because the Ioniq is more efficient at an estimated 4.5 miles/kWh even at the same charge rate it will be able to add range faster (see: Miles of Range per Charging Minute).
Each bar in this graph represents the Number of Charging Minutes required to add 100 miles of Range for different STARTING states of charge (SOC). It is another common comparison metric. This graph shows the values for both the VW ID.4 and the Hyundai Ioniq. Note that because the charging rate (power) will be reduced as the battery 'fills', the 100 miles of charging is faster when the battery is nearer to empty.
Although this "Miles of Range per Charging Minute" graph is not seen as often as the charging curve above, it really is a better comparison tool as it includes the efficiency of each vehicle. In this case, the Ioniq will have its values 'improved' by its better efficiency.
