The BYD Seal AWD is not four-wheel drive

Quick translation of the summary:

The BYD Seal in all-wheel drive version turns out to have substandard four-wheel drive. In our test, two different examples of the Seal AWD drive only on the rear wheels. The front wheels never intervene to take the car out of the situation.

The test car's rear-wheel drive behaviour makes us doubt whether we have got the right car. Perhaps it is the entry-level model BYD Seal Design with rear-wheel drive we have borrowed from Hedin Bil? But no, according to the registration certificate, the test car should drive on both axles and when we look into the front wheel arches we see drive axles there too.

On a snow-covered and slippery slope in Sälen, however, it does not drive with the front wheels and when we test the system on zero-friction rollers on the slope of the editorial garage with an eight-degree slope, it behaves the same way: rear-wheel drive.
