The tested version of the BMW iX electric SUV has an EPA range of 315 miles (507 kilometers)
In a recent test, the SUV drove 377 miles (607 kilometers) on a single charge
German EVs often have substantially longer ranges than their EPA figure suggests
The iX is one of the two new electric vehicles from BMW, the other being the i4. According to the EPA, this midsize SUV has a range of 324 miles (521 kilometers) when equipped with the standard 20-inch wheels or 315 miles (507 kilometers) with the optional 22-inch wheels.
The tested vehicle had the larger wheels, which means it should have an average energy consumption of around 39 kWh per 100 miles (161 kilometers). This is impressive for a vehicle in this category since many smaller EVs are less efficient, but the real-world numbers are even better.
Indeed, the BMW iX xDrive50 that was tested by Edmunds needed 18% less energy per 100 miles and was able to drive 62 miles (100 kilometers) more than the official figures show.
This range improvement made it possible to cover 377 miles (607 kilometers) on a charge, which is not only 19,7% more than expected, but also more than any other electric SUV in its category.
This is not the first time an electric vehicle has been able to achieve higher efficiency and range numbers in the real world compared to the EPA figures and even the related BMW i4 was able to add 18,1% to its estimated range.
Interestingly, German electric vehicles seem particularly underrated in the EPA tests, which leads to them routinely beating their estimated range by a noticeable margin in independent tests and in the real world.
Something that could explain the iX and the i4’s long range is the electric motors that BMW developed especially for them. This new type of motor is smaller and lighter than conventional units while being more powerful and requiring less rare earth materials to manufacture.
