Brand new car with no break in. Appears to just floor it in sport mode. Also not sure how the time was measured (just time lapse on the video?). I am sure the auto mags will get times that are a good bit faster (the 500+ lb more / down 10 hp & 30 ft-lb Edge Sport was seeing 60 in 5.6 seconds) with a better launch.
But the Auto GT-like claim appears to be laughable.
