From an exchange during the Le Mans race thread:
Diffey mentioning the flying Merc, a good reminder of why they will never be back. That shame will not wash off.
BMW and Porsche flipped too. I refuse to believe Merc won't look at Le Mans. I hope Hamilton makes them go.
If they came back after 1955, which was something to really be ashamed of, they can come back again.
Yeah, it will be too tempting for some Mercedes chief one day to make it their mission to redeem their brand at Le Mans.
To preface, F1 is evidently working just fine for Mercedes for the moment, so I don't expect any immediate change of heart. But these things are always cyclical.
If Mercedes did return to Le Mans and won it overall, that is surely the redemption story of all redemption stories. Probably even more so than Ferrari's triumphant return.
Could a "golden age" of manufacturer involvement for overall honours tempt Mercedes back to Le Mans in the years to come? I think and hope so. Or is the risk too great for the brand?
