Can you imagine any of the current generation of race drivers doing this for a sponsor?
FYI, it's not mentioned in the ad, but the car is driven by Fred Gibson, who was also a Ford sponsored driver in the 1970's, before moving to Nissan and eventually managing the team when Jim Richards was driving "Godzilla"...
Interesting continuity error. That is shot on a banked oval track at the Ford Proving Grounds down the near Little River and the You Yangs. Google Map view
In the initial shot, where they say "the car is now travelling at...", it is plainly going anti-clockwise around the track.
Then they show the drivers, and you can see the track curving off to the left in the background, so plainly the car has turned around, and is now going clockwise around the oval.
It's on the east side of the oval, you can see the road off to the east of the oval on the other side of the grass at the end of the video.
