A racing test tunnel no one wants to talk about (opens in new tab)

The article was put online in 2014 but had previously appeared in print.

Indeed, this article offers nothing new about the tunnel.

The author specifically mentions that article.

That's not the only thing they were doing. The article also mentions braking tests, and pulling all kinds of telemetry. These things aren't new, but being able to do all these tests and measurements on a full-sized car in a controlled environment is rather unique.

It is also common place in F1, particularly during winter testing and occasionally FP1.

Old abandoned tunnels are cool. Racing dude bought one in PA to test his cars in a controlled environment since scale models in a test tunnel don't behave the same way as real cars driving fast. Was a big open secret, apparently recently banned by NASCAR and Indy for no good reason. Also, tunnels are cool.
