What? What's your source? Actually I don't see how, by changing two elements, it can affect the final speed. I mean, it's not shorter than the previous layout. Can you tell us more, please?
http://projekthelix.se/ny-banlayout-efter-launch-2/ is my source
Liseberg sais that the highest point after launch 2 will be taller with the Inverted Top Hat (almost 40 m)
Instead of an Twisted Hump and a Corkscrew they will have an Inverted Top Hat and an Airtime Hump, the reason why they did so is that they are not sure if the trains would get the power to reach the station.
They have also added a Corkscrew to the start of the coaster, right after the train leaves the station.
The CEO of Liseberg said they where planning another coaster than Helix, it was going to be so tall that you could look down on uppskjutet (spaceshot), but they decided to make a better coaster. "Tallest is not necessarily the best. And the fastest is not necessarily the most fun." said Lisebergs CEO.
