The funny thing is that during the event, Elon claimed that the car can recharge the tanks itself [0], but in the Top Gear video, the Tesla folks say that it is recharged from an external source [1]. In the Top Gear video, they also say that they are filling it from a "high pressure nitrogen system", whereas Elon claims that the tank is filled with air. They can't even keep their own messaging straight.

I assume it's both...
it has its own pump, but if you don't want to wait 6 hours to recharge, you can fill it with a nitrogen cylinder.
He's only 78% correct.
promise everything now, work out everything else later.
Perhaps they use liquid nitrogen and then just allow it to boil off inside the tanks? This would give them a safe and easy way to quickly recharge the tanks for testing.
It's pretty simple, actually, Elon is a pathological liar.
Elon _always_ lies and exaggerates during these things. He seemingly can't stop himself.
