CGI Model

In 2010, Sidney was modelled in full CGI by Nitrogen Studios for the 2011 film, Day of the Diesels. The model was "hand-sculpted" in Maya, a 3D animation and modelling software. According to Greg Tiernan, the CGI models are subjected to many rounds of review before they are submitted to HiT Entertainment for final input and approval.

Prior to being given a name, Sidney was referred to as "Temp Diesel C". As stated in concept art, his model is a retexture of Diesel with a new face. The concept art itself is edited from 'Arry and Bert with added ladders from Diesel; however, his final model reuses Diesel's body mesh as per the listed instructions.

While Nitrogen Studios rigged his face and upper body for Day of the Diesels, Arc Productions rigged the chassis later for The Missing Christmas Decorations. Issues with his rigging resulted in his wheels turning half the speed they should be.
