Speed of Sound is a Boomerang coaster in Walibi Holland in the Netherlands. It is manufactured by Vekoma and opened in 2000 as "La Via Volta". It operated until 2007 when the park announced it would be shut down. In the same year, the train was sold to Pleasurewood Hills to be operating on Wipeout, also a boomerang coaster. On January 30, 2011, Walibi World announced that the roller coaster will reopen in 2011, with a new style train from Vekoma. The coaster was renamed to Speed of Sound and the track was painted orange.
