Yes, every EV and every hybrid has regenerative brakes and traditional calipers/pads as well. Including Tesla, including the I-Pace. All of them.
From the latest info I have from engineers, the Tesla MS/X regenerates only when you lift the accelerator. The brakes do not trigger regen, they are friction only. Not sure about the Model 3.
Blended brakes cost more and are harder to program. It's cheaper and faster not to engineer them.
It would really easy to tell if there is a kW meter on the i-Pace or Tesla. Get going about 75 mph or whatever you feel is safe. Apply the brakes lightly and record the negative kW. Now do it with a firm brake pedal. The regen should read much higher if it has blended brakes.
This is why Tesla MS/X have poor city efficiency.
