Singer Vehicle Design reveals the All-terrain Competition Study

At the request of a long-term client, Singer has looked to a golden era of Porsche rallying in the 1980s and to automotive heroes including the 911 SC/RS and the 959, to reimagine its air-cooled 911s as World Rally Championship-inspired, all-terrain competition machines.

Singer's latest services will enable its clients to go off-road racing, with a Porsche 911 modified by Singer for all-terrain use. The All-terrain Competition Study (ACS) has been undertaken by Singer in partnership with renowned 911 rally specialist Richard Tuthill, in response to the request from the 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 U.K.-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 fourth win in the gruelling 5,000km event across Kenya and Tanzania. These successes sit alongside deep expertise from the world of WRC competition and events such as the Paris-Dakar.

Modification services developed for the Porsche 911 Reimagined by Singer ACS include off-road competition capability conceived with events such as the Baja 1000 and Dakar Rally in mind as well as dramatically increased ride height, suspension travel and overall strength.

The body panels are made of carbon fibre to allow for quick replacement and easy underbody access. The engine is a twin-turbocharged 3.6-litre air-cooled flat-six with power producing 444bhp and 569Nm of torque mated to a sequential racing transmission with front, centre and rear limited-slip differentials, sending power to all four wheels with a full-time all-wheel drive system.

The ACS uses a 1990 Type 964 Porsche 911 body as its base, and the body has had core strengthening to the monocoque for heavy duty off-road use.

The ACS is also fitted with specialised long-travel suspension with twin, five-way adjustable dampers per corner for a total of eight dampers on the car. 16-inch wheels are fitted with BF Goodrich All-Terrain tyres, and four-piston brakes with a hydraulic handbrake help the car to stop.

As the ACS was built with desert racing in mind, it is also fitted with a long-range fuel tank, two full-sized spare race wheels and tyres in front and rear storage area, a roll cage, racing seats, a rehydration system for driver and navigator and a GPS race navigation system.
