Just a thought that occured to me, and wondered if anyone knew the answer for sure.
Basically, I remember not so long ago that teams would sometimes change cars during a season, or use the previous year’s car partway through the season before introducing the new one. I know this doesn’t happen any more, with teams rolling out effectively a new car every season and then binning it at the end of the year.
But what got me thinking is that McLaren are struggling a little with their new car. Now I fully expect them to work on it and make it work properly, at which point it will all pay off. But imagine it didn’t for a moment, and they realised that the new car was a mistake and last year’s car would be quicker.
Last year’s car would still be more or less legal, barring a couple of tweaks, and has passed all of the crash tests and so on. So would there be anything stopping them from just showing up with last year’s car to do back to back tests, or run the older car in a race?
They definitely used to be able to do this, but I wonder if that’s changed and now they’d not be allowed. Anyone know?
