Here is a video of two BMW looking things. They used to be e92 M3 s, yes. But that's the past! Have a look how brutal drift machines they have become!

Unfortunately I could get small information pieces only from the purple/blue car. It has an LSX Compressor engine which can produce 720 - 750 hp added to a Samsonas sequential gearbox. As for the torque, it gives about 900 nm from 2000 rpm already. Probably the other car doesn't differ too much...

Enjoy!
