Cayman reviews and LSD

[Chewey]

I am trying to clear up whether most of the reviews out there are on PVT equipped cars.
In the Chris Harris videos (yellow cayman) he is able to slide the rear in a way that only an LSD should allow.
Without LSD I would expect the inside wheel to spin up, but this never seems to happen. Plenty of double black lines.

Does anyone know if LSDs (Prosch Torque Vectoring) are present on most of the review cars?

I don't believe there is a configuration with LSD but without the silly brakey thing.

Steve Sutcliffe doesn’t mention that the Sapphire Blue CGTS in the Autocar video has PTV.
The red one however in the twin test with the F Type is equipped with PTV
My instructor at PEC advised me to save my money as PTV not noticeable in everyday driving and certainly I didn’t miss it on my experience day in the GTS
