When the Tonnerre de Zeus opened, it had two blue trains by PTC. For the 2004 season two new PTC trains were purchased -- one red and one blue.
'Tonnerre de Zeus' is French for 'Thunder of Zeus'.
After the ride's large overhaul/refurbishment, it will be renamed 'Tonnere 2 Zeus' in 2022. The new name refers to the redesigned ride but the pronounciation is a small play on words as well. '2' in French is pronounced as 'deux' which strongly resembles the simple 'de' from the coaster's original name.
Over the winter seasons 2019, 2020 and 2021 The Gravity Group did a systematic retrack of 'Tonnerre de Zeus'. When the phased refurbishment will be finished in 2022, The Gravity Group will also have altered some parts of the layout (banking of curves, adding of small hills/hops, a 90° banked hill,...) which will result in more airtime. The trains will be replaced with two trains by Gravitykraft Corporation. On each train the final row of two seats will be facing backwards.
In Greek mythology, Zeus was the king of gods, and is associated as being a weather god. His weapon was a thunderbolt, which he hurled at those who displeased him.
