SSC Tuatara revealed in Shanghai

Jerod Shelby reveals the SSC Tuatara in Shanghai We finally discovered last month that Shelby Supercars wouldn’t be calling their new Veyron-bashing hypercar the Ultimate Aero II (which seemed logical) but has instead taken a leaf out of Pagani’s ‘Book of obscure names for Supercars’ and decided on SSC Tuatara. Yep, SSC has named their hypercar after the Maori name for a lizard, a lizard with the fastest evolving DNA of any creature (doubtless the motivation for Jerod nicking the name for his car). Interestingly, a comment on the story we ran about the new SSC getting the Tuatara moniker said that as well as having the fastest evolving DNA of any creature, the Tuatara “…puts a tortoise to shame in the slow moving stakes, and is also regarded as a living link to the dinosaurs” which, for Jerod Shelby’s benefit, we should probably gloss over.
