Here’s onboard from the Porsche at Spa, alongside Hamilton’s qualifying lap.
It’s fascinating to watch. The 919 gets a good lead early on but the Merc actually catches up during the mid-lap sequence and gets close enough to be equal by Stavelot, but then the Porsche takes off again and is way ahead before the bus stop. I put it down to being very slippery at high speed while still having just enough downforce to put in a good show in the tight stuff. I’d love to see what would happen if you put a Formula 1 PU in the back of the Porsche; would it be faster or slower?
In its current guise Porsche would eat a Formula 1 car at a long track like Le Mans.
