The first video isn’t really worth watching, unless you care to listen to a patriotic sales pitch on the Corvette and an American making a big deal of pointing out the Lotus 49 had an Ford Cosworth DFV engine.
On point though, I was really surprised to hear that the Lotus actually exerted it’s advantage under acceleration and not through the corners and under braking. I was expecting that despite the fact it lacks the modern tyres, suspension, electronics and brakes of the Corvette that the much lower weight would more than offset it’s handicaps, only for the advantage to be clawed back on the straights by the bigger engined Corvette!
One other thing I noticed though was how this video illustrates just how far F1 cars have progressed in over 40 years: the braking distances are far smaller now; a modern F1 car can carry so much more speed through the essess, showing up the aerodynamic advantage they hold; turn 10 is a flat-out kink in a modern F1 car, but in the Lotus Rossi had to visibly lift off and what I thought was the most telling aspect how much understeer the Lotus suffered through turn 17 – it got nowhere near the apex!
Here is a video of Vettel’s pole lap last year at the same circuit: if you watch it after the on-board of the Lotus that @andae23 has kindly posted the differences become highly apparent:
Very possible – I guess that since it’s a piece of history they have to protect it! If we were to re-incarnate a full-paced qualifying session then indeed I think we’d be seeing profoundly quicker laptimes from the Lotus, still though I do find it interesting comparing it and the RB8 @andae23!
