This is a recent "Smoking Tire" review of the Grand Touring Performance, comparing it to their earlier test of the Dream Performance.
I think it's spot-on on every single point they brought up, from the Air's exhilaration as a driving machine and its roomy luxury as a passenger conveyance to the continuing burps and foibles of its software. The discussion about range hits the nail on the head: not what it's touted to be, but still the best long-distance runner in the industry at high speeds.
