In this video, I will do a range test with the VW ID.4 GTX with the 77 kWh battery. I am going to test the range on the highway in order to test the minimum range of the Volkswagen ID.4 GTX to find out. Next, I am going to do a range test at lower average speeds in town and on country roads to determine the maximum electric range of the VW ID.4 GTX to find out. I am also going to do a charging test at a public DC fast charger to find out how much range is added after 30 minutes of fast charging. Here you can see the full POV test drive viewing with the VW ID.4 GTX.
The VW ID.4 GTX is an all-electric car with a WLTP range of 480 km. It has a lithium battery with a net capacity of 77 kWh. The GTX is the new high-performance ID.4 model. As with GTI and GTE, this represents a separate product brand.
It has two electric motors: one on the front axle and one on the rear. Combined, they deliver 299 horsepower and work together as electric all-wheel drive. The car’s top speed is electronically limited at 180 km/h. When you drive slowly normally, the car is driven by the rear engine. This offers better efficiency, which ultimately gives you better coverage. Moreover, if you need more pulling power, the engine on the front axle is activated within a few hundredths of a second. In sport mode, the front electric motor is always activated.
I’m going to test the range on the highway first. There is also some brief sporty driving on country roads in this test. The purpose of this part of the test is to find out the minimum range of this car by testing it at higher average speeds. At the beginning of this part of the test, the battery is at 88%. I did the test in January and it was between 6 and 7 degrees during. It also rained a lot that day.
We begin with a 59-km ride, purely on the highway, at 120 mph. This was a ride from Brussels to a region near Namur. The battery is down to 68% and the average consumption is 25.8 kWh. I will base my estimated range on consumption and net battery capacity. The total range based on this consumption is 298 km. I now leave the highway for some sporty driving on country roads. After this 28km stretch, the total average consumption is 25.3 kWh. The range has now been increased to 304 km. Now we drive all the way back along the highway towards Brussels. Let’s look at the end result.
The battery dropped to 36% and the total length of the ride was 146 km. Average consumption was 25.3 so total highway range is 304 km.
| Battery% | Distance (km) | Consumption (kWh) | Temperature (°C) | Estimated range (km) |
|---|---|---|---|---|
| 88% | start | 7 | start test | |
| 80% | 23 | 26,0 | 7 | 296 |
| 75% | 36 | 27,4 | 6,5 | 281 |
| 70% | 50 | 27,4 | 6,5 | 281 |
| 68% | 59 | 25,8 | 6 | 298 |
| 60% | 78 | 25,9 | 6 | 297 |
| 58% | 87 | 25,3 | 6 | 304 |
| 54% | 96 | 25,8 | 6,5 | 298 |
| 50% | 106 | 25,9 | 6,5 | 297 |
| 45% | 118 | 26 | 6,5 | 296 |
| 40% | 136 | 25,7 | 7 | 300 |
| 36% | 146 | 25,3 | 7 | 304 |
The VW ID.4 GTX is equipped with CCS (combined charging system). This system allows the ID.4 GTX can be charged with both AC and DC. For this test, I am charging the car on a DC fast charger. This car can charge quickly at speeds up to 125 kW. It can be charged from 5 to 80% in 38 minutes.
I am going to do a test of 30 minutes of charging. At the beginning of the test, the battery is at 22%. I charged to 66% in 30 minutes. I gained 36 km after 10 minutes, and then about 49 km after 20 minutes and 50 km after 30 minutes of charging. So in total I gained 135 km of range at 30 minutes. The charging speed was between 62-73 kw, which is not the expected 125 kW. It was very cold that day, between 2.5 and 3.5 during my charging session, so perhaps this played a role.
How long would it take to fully charge the battery with this DC fast charger? Well at the beginning of the charging session the car indicated that it would take 1h10 to fully charge the battery.
I have not done an AC charging test with the GTX model. Over the summer, however, I did an AC charging test with the regular VW ID.4, also with the 77 kWh battery. Charging is the same as the GTX, so this should be relevant information.
I charged the car at a public charging station in Brussels. This public AC charging station has a charging speed of 22 kw, but the Volkswagen ID.4’s built-in charger has a charging speed of 11 kw, so this is the charging speed that we got. It took me 5h05 min to charge the car from 22% to 100%. Temperature was 15.5 degrees.
Now let’s test the range at lower average speeds in the city. I want to know what the maximum range of this car could be. Let’s take a look at my results. The weather during this part of the test was a little different. It wasn’t raining, but with temperatures between 3.5 and 5.5 degrees, it was still a bit chilly. At the beginning of this part of the test, the battery is at 61%.
The first leg was about a 24 km ride in Brussels. I averaged 19.3 kwh which resulted in an estimated range of 399 km. The rest of the ride I drove around in Flanders. Still in an urban area but with many opportunities to just smoothly pass through to drive.
I further drained the battery to 33% over a total 107 km ride. Over the course of the trip, consumption dropped to 18.2 kWh. The range in the city is thus 423 km.
If you’re interested in watching my range test with the rear-wheel-drive ID.4 with 77 kWh, I’m going to link to that video below. In terms of range, it will not be 100% comparable to the GTX. The GTX has a WLTP range of 480 km, while the rear-wheel-drive 77 kWh version has a range of 520 km.
| Battery% | Distance (km) | Consumption (kWh) | Temperature (°C) | Estimated range (km) |
|---|---|---|---|---|
| 61% | 3,5 | start test | ||
| 55% | 24 | 19,3 | 4,5 | 399 |
| 50% | 41 | 18,7 | 5,5 | 412 |
| 45% | 62 | 18 | 5,5 | 428 |
| 40% | 82 | 18,3 | 5 | 421 |
| 35% | 98 | 18,3 | 5,5 | 421 |
| 33% | 107 | 18,2 | 5,5 | 423 |
As a conclusion I can say that the range of the VW ID4 GTX is somewhere between 304 km and 423 km, based on similar driving conditions and measured in quite cold temperatures between 3.5 and 7 degrees and also with a lot of rain during my highway range test . I estimate that in much colder temperatures you probably get less range, in warmer temperatures you get more range. I would say around the WLTP range of 480 km. With the regular ID.4, for example, I got more range in the summer in the city than the WLTP range. Here you can view the driving range test of the VW ID.5, the Skoda Enyaq iV and the Audi Q4 e-tron.
