It's Alonso driving a Renault Sport Street car in the old circuit Nordschleife, with Spanish F1 Tele5 presenter, Antonio Lobato as co-driver.
Some funny comments for non-Spanish speakers:
Lobato said there is not need to go so fast.
AL: Do you imagine yourself self driving a F1 car on this circuit?
FA: tsk tsk, Impossible!
AL: but they did it in the past
FA: there were other formula 1, I suppose.
Alonso turns the A/C off to go faster.
FA was driving at +200kmh.
He overtakes the red car and discovers that it's a girl who is driving very fast and exclaims: It's a girl!!
I hope you enjoy the ride, certainly Antonio Lobato did
