I have a new favorite engine.

Read the press release.
6.2L, 622hp... 8000RPM!
AFAIK, no one has ever put a 8000RPM V8 > 5L in a production car. Someone correct me if I am wrong. Piston speeds must be nuts. Oh and max power is at 7400RPM, so in theory there is more power to be had here (probably in exchange for some peak torque).
