At the request of a client, Singer, in partnership with 911 rally and motorsport specialist Richard Tuthill, has reimagined the air-cooled 911 as World Rally Championship-inspired, all-terrain competition machines.
Rallying fans will now be able to go off-road racing with a Porsche 911 modified by Singer for all-terrain use. The All-terrain Competition Study has been undertaken by Singer, in partnership with 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 all-terrain capabilities.
The client 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.
Modifications developed for the Porsche 911 by Singer include:
- Off-road competition capability, with events such as the Baja 1000 and Dakar Rally in mind
