Theres tons of events that do hill climbs in the usa... in oregon theres the wmc that does a hill climb once a year. Its really fun but very dangerous.... usually have to have a rollbar or cage to do it.
Here is a video of my friend doing the wmc hill climb in his old 06 subaru sti with 500hp. Not as cool as the audi or peugot rally car but this is also a amatur event for hobbies... not professional drivers.
