The All-terrain Competition Study has been undertaken by Singer, in partnership with renowned 911 rally specialist Richard Tuthill, in response to the request from their client for modifications to his air-cooled Porsche 911 that would enable the car to compete in off-road racing and to demonstrate extensive all-terrain exploration capabilities.
To highlight the broad repertoire of the ACS, the client has commissioned two machines, one -in Singer’s iconic Parallax White -focused on high-speed desert rallying and a second–in Corsica Red -configured for high-speed, high-grip tarmac events and disciplines.Porsche 911s prepared by UK-based off-road competition specialist Richard Tuthill have dominated rally events for decades, with recent victory in the 2019 East African Safari Classic marking a remarkable 4th win in the grueling 5000km event across Kenya and Tanzania.
These successes sit alongside deep expertise from the world of WRC competition and events such as the Paris-Dakar.
