Default Do I have rear axle steering?

I have a 2018 991.2S with sport package which is suppose to have RAS, but I have had someone look at the car when I'm make a sharp turn in the parking lot and the rear wheels are not moving? Can you look under the rear of the car and tell?

you can visually check for the motors on the rear hubs, they're near the top, slightly over to the side towards the front of the car.



the amount it turns is very subtle. I've got a video somewhere of actuating it lock-to-lock, I'll post it if I can find it.

On the Taycan I noticed if you’re behind the car you can see the rear shimmy side to side, like a tail wag, as you turn the wheel. It’s real subtle, maybe 1/2” or movement, but if you’re close to the car you can see it clearly. The wheel movement itself seems very slight maybe just 1-2 degree.

Those photos were exactly what I needed to confirm that I do have RAS! As always the technical expertise here excellent!
