Singer modifies Porsche 911 for all-terrain competition

(January 6, 2021) LOS ANGELES — At the request of a long-term client, Porsche restoration company Singer has looked to a golden era of Porsche rallying in the 1980s and 1990s, and to automotive heroes including the 911 SC/RS and 959, to reimagine his air-cooled 1990 Type 964 911 as World Rally Championship-inspired, all-terrain competition machines. Singer’s latest services will enable clients to go off-road racing, with a Porsche 911 modified for all-terrain use.

The All-terrain Competition Study has been undertaken 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 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.

“So much of what we’ve done for the last decade has been inspired by Porsche’s competition success and the All-terrain Competition Study provides us the opportunity to showcase that idea literally and vividly," said Rob Dickinson, founder and executive chairman, Singer Group Inc. 'We at Singer are motorsport nerds in our hearts and demonstrating our understanding of the discipline required our off-road vision to display deeply legitimate competition credentials from the structural engineering, to the bodywork ethos, to the mechanical package."
