The amount of sensors they have on the cars is insane. Each race they basically set up a data center in the paddock. Then that is remote linked to the teams HQ DC over MPLS links.

Here is a quick bit about it.

I have no idea actually. The kit they had was amazing though. My favourite was the machine for testing their radio link. It was a long room full of baffles and at one end they put the receiver. At the other end was a large machine that spent all day shaking the life out of the transmitter.

In the electrical testing room they had a few car simulators that effectively had the whole car in (they were about 5 ft tall from memory, large boxes). The could start them up and run the entire system physically.
