Hey there, there are a bunch of interesting comments here explaining the tech already so here are a few things not mentioned yet: Basically it's purpose is extra downforce usable during low speed&decel, since it only works off-throttle. In 2010, Red Bull introduced the first blown diffuser into the sport and instantly proved how well the design worked.
In 2011, the entire field was experimenting with this tech which is basically just cutting spark under decel so unburnt air/fuel mixture gets into the glowing exhaust pipe, just like a semiautomatic transmission in a rally car. In any conventional car, the exit direction of the exhaust is pretty much non-essential for aero but if you combine the exhaust with the diffuser which guides air from under the car out the back and dump a lot of unburnt fuel into the exhaust, the exhaust gas combined with the natural air flow creates a so called "Venturi effect", which describes how low/high pressure air interacts with air moving in a different direction. It's responsible for how a carburettor, sails on a boat or candles work. The sound is indeed incredible but I think it was viewed as something to gladly be patched out by next season regulation changes since it's advantage was not seen as in the spirit of the sport, which is a fishy way of the stewards saying "You've built something we didn't think of doing ourselves. You get to have your toy for 1 season but then it's gone for ever", which means race teams make hay while the sun shines and made for some of the most spic championship campaigns.
Phew, that got longer than expected. Hope your week is going well!

It was a very curious situation. The TGV since 1981 held the world train speed record with 381 km/h or 236 mph. Then, Germany set out to beat the French with their ICE, and in 1988, the newly developed InterCity Experimental reached 407 km/h or about 252 mph. This was an attack on the national pride, and thus France beat back in 1989 with 482 km/h or 300 mph. Then Alstom said, we can do it better with more preparation, and in 1990, the TGV Alantique reached 515 km/h or 320 mph. For about one and a half decade, that was the world speed record for rail based, manned vehicles until 2007. This history line was also why the driver anounced the speeds of 380, 400, 480 and 515 km/h.
PS: France held the world speed record for trains for very long times, reaching 331 km/h or 205 mph already in 1955.
PPS: The train set is still in regular operation. That means you can buy a ticket and ride on the exact train that still holds the world speed record for trains.
