How fast is that compared to a super car, like say a GTR/Lambo?
From what I can see in the video, the Mk2 in question is running a 9 second 1/4 mile. The Astra VXR it is up against runs a pretty respectable 14.6 so it would seem the timing at the strip is pretty accurate.
To put that into perspective, a Bugatti Veyron runs a 10.4 second 1/4 mile.
