The battle rolls on to Australia for a coaster that shoots riders backwards at 100 mph, then to Germany for a ride that twists down two 360-degree corkscrews, then to the U.S. for a monstrous 5,000 ft. coaster.

The battle rolls into Germany for the tallest wooden coaster in the world and also an insane 90 mph coaster in Canada and a gut-wrenching 4g coaster in the United States - which coaster will crush the rest?

The international competition rolls on to a Japanese coaster that rockets riders 110mph in 2 seconds, to a gravity defying 4.5 G coaster in Germany, to the U.S. for a coaster that plummets riders 23 stories.
