During Formula 1 weekend, there are a collection of other races on the track between the F1 practice and qualification sessions and one of these is run with a collection of classic cars. Many of these, I remember watching as a kid and it’s great to see them back on the track.
In this case, although I thought this was a 1970s-era Tyrrell based on the livery, I’m informed that it’s likely a March Ford from Formula 2. Regardless, it looked good on the track.
