Suspiciously close times... there's some chat on the interweb that it's not all cosher.
Chris Harris has a 'coming soon' video on his YT channel for the same 3 car test... that should be a good one
Edit;
I think the CH test has full manufacturer support. So Porsche will drop their well used demonstrator off and ask for a quick 'phone call when it's ready to be picked up. McLaren will send a truck, a 10 man support team and 10 sets of tyres. Ferrari will do a week of testing at the venue, before turning up with 2 trucks, a 50 man support team, 100 sets of tyres and a LaF with a secret 2nd engine fitted to it
