I mean if the next Z is based on the platform of the current car, then I'm sure it's fairly easy to use the current car as a surrogate to test the driveability/reliability/etc of the drive/powertrain for the upcoming car. I'd be interested in knowing what the car in the images sounded like. Could you hear the turbos? Did the car sound like it was using a manual transmission or something like a DCT? The pics alone aren't telling us a whole lot.
