Interesting. I will be on a lookout for this. I've experienced less braking capability on others cars (including Tesla) when braking for the first time after driving in a cold wet PWN environment. However I when I did one of my weekly 3am drives in the PNW rain, I actually expected wet brakes when exiting the highway but didn't experience that in the Taycan (I've only had the Taycan for less than a month). I was thinking to myself "good job Porsche".I'm glad there's a complaint. Maybe Porsche will actually look into it.
I've witnessed a few times that the brakes didn't engage nearly as much as expected and I had a distinct "long pedal feel" followed by a panicky slamming of the brakes. Always happened to me during conservative driving early in the morning, in the cold and wet (ie when the car is 'cold soaked'). Not very reproducible, I'd say it happens about once a month when driving daily here in the PNW winter.
I definitely feel and hear the first portion of first drive of the day when regen is off in order to scrape any rust off my brakes. So while not perfectly seamless, Porsche blended braking so far has me generally impressed.
Tesla solution is brain-dead simple - regen is only controlled by letting off the accelerator, bake pedal controls the mechanical brakes all the time - doesn't take regen into consideration (the driver will, since once they take their foot off the accelerator, the regen braking happens, so driver will not press the brake pedal as hard). When battery is too cold or too full, the regen is limited or off, which can generate a feeling like your brakes are bad, but that's because you have to press the brake pedal, therefore engage mechanical brakes, harder than if regen was on. That was something I was hoping Porsche blended brakes would eliminate, plus Porsche can regen over 4 times more than Teslas (in the right conditions), thanks to blended braking.IIRC Tesla also faced an issue where the auto-regen braking in some cold conditions had unexpectedly weaker braking. I wouldn't be surprised if this is the kind of stuff all the different companies need to work through as they launch their EVs. Where Porsche is different from Tesla is that Tesla has the actual brake pedal always skip past regen into normal braking, so Tesla avoids the "oh shit" feeling when the actual brake pedal seems to be too weak.
