Singer launches striking ACS concept

Singer, the California-based bespoke Porsche restoring firm, has announced the development of a stunning all-terrain racing machine, called, for now, the All-terrain Competition Study.

Developed to satisfy the request of a long-term client, Singer was inspired by the golden era of Porsche rallying in the 1980s, and particularly models such as the 911 SC/RS and 959, in the development of the ACS. With permission from the commissioning buyer, the ACS will become part of Singer's product offering, enabling clients to go off-road racing.

After receiving the request from its long-term client, Singer turned to renowned 911 rally specialist Richard Tuthill for assistance. The client actually commissioned two machines, one - in Singer's iconic Parallax White - focused on high-speed desert rallying and a second - in Corsica Red - is configured for high-speed, high-grip tarmac events and disciplines.

Porsche 911s prepared by UK-based 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.

As is the case with all Singer's restoration services for owners of the Porsche 911, the car takes the 964 generation of air-cooled cars as its starting point. At the heart of the machine is an evolution of the famous "Mezger" air-cooled flat-six, here in 3.6L form, with twin symmetrical turbochargers and fly-by-wire individual throttle bodies. The performance characteristics of the engine can be tuned depending on the demands of competition and the owner.

A bespoke carbon fiber body is optimized to allow easy access to mechanical components at service stops and to enable effective breathing and cooling for the powertrain. The use of carbon fiber allows Singer to reduce overall mass and, for this car, to offset the extra weight of the roll-cage.

The All-terrain Competition Study draws on Richard Tuthill's extensive knowledge of the demands of both on and off-road racing. The bespoke suspension and damping, together with AWD configuration is designed to enable effective deployment of the car's power off-road. The strength designed into the car's structure and components is a response to the forces encountered during high-speed, off-road endurance events and pathfinding.

Inside, the ACS reflects the demands of off-road racing. FIA specification seats and harnesses sit within a full roll cage. The car is equipped with a race GPS navigation system while both driver and navigator have access to in-seat rehydration systems.

As is the case with all Singer vehicles, each car is approached as a bespoke restoration and Singer's special wishes personalization approach is available. The price for the restoration services based upon the results of the All-terrain Competition Study will be dependent on the specification chosen by the owner.
