577 kilometers is the official range of the BMW i5 eDrive40. But what is the real reach? So how far do you get when driving down the highway at 100 km/h (or 130 km/h)? We test that!
Large wheels make a car less efficient. It is possible that our test car with 20-inch alloys has a WLTP range of 548 kilometers, instead of the 577 kilometers that BMW communicates for a basic i5 with 19-inch wheels.
The battery of the BMW i5 has a net capacity of 81 kWh, regardless of whether you order the 'good' i5 eDrive40 with 340 and 400 Nm, or the very strong i5 M60 xDrive (601 hp, 820 Nm). The even bigger, more luxurious and more expensive one BMW i7 is the boss with a usable battery capacity of 101.7 kWh. That large battery will be discussed again later.
It is 7 to 11 degrees outside, so the temperature is not too bad for the time of year. It is quite windy, but when driving around, the i5 sometimes has a headwind and other times a tailwind. We drive our 100 kilometer test lap at 100 and 130 km/h. Here are two consumption figures and we use them to calculate the range of a full battery. We assume 81 kWh.
At 100 km/h, the new BMW i5 has an average power consumption of 19.5 kWh/100 km under these weather conditions. If you drive a full battery with a usable capacity of 81 kWh completely empty, you will arrive 415 kilometer ver.
Let's take the Mercedes EQE range added, we see that an electric sedan can also make do with 17.8 kWh/100 km. But the EQE was tested on a beautiful spring day. More sun and less wind can explain that difference in power consumption.
The i5 has a top speed of 193 km/h, but we'll hold back. We drive our test lap at 130 km/h and come home with a consumption of 26.8 kWh/100 km. The result is a 130-km/h range 302 kilometer.
Many EV buyers are rubbing their hands with a realistic range of 415 kilometers. But the BMW i5 driver devours kilometers as if they were car drops and that may not be enough.
Suppose BMW were to offer the large battery of the i7 as an option for the i5, then you would have no less than 101.7 kWh at your disposal. The result is a serious range of approximately 520 kilometers. Look, you'll get somewhere again.
About those 415 kilometers: that is when you obediently drive one hundred. Make that 130 km/h because you're in a hurry and suddenly there's only 302 kilometers between charges. That's a decent range, but it's not great. And doesn't BMW pride itself on making driving great?
