A 911 to race the Dakar. Classic and extreme at the same time. At the request of a customer, Singer developed the ACS by looking back to the golden age of Porsche rallying in the 1980s and the models of the German marque used in those races, such as the 911 SC/RS and 959. The manufacturer imagined a classic air-cooled 911 as an all-terrain competition car strongly inspired by the models that run in the World Rally Championship.

The result is the Singer ACS (All-terrain Competition Study), a model developed by the Californian manufacturer together with the famous British Porsche 911 tuner Richard Tuthill. The owner commissioned two cars, the first white, mainly designed for high speed rallies on desert terrain, the second red, for speed races on asphalt.

The model being prepared is a 1990 Porsche 964 that has had its monocoque core strengthened, its body panels replaced with new ones in carbon fibre, new suspension with adjustable double dampers and new steel disc brakes with hydraulic handbrake installed, and much more. The aesthetic interventions have concentrated on a pure surface treatment, characterised by soft shapes faithful to the original model with a few peaks of flair, such as the large spoiler that dominates the rear, the double exhaust tailpipe positioned high up and the new cut of the mudguards to house the huge forged aluminium wheels. The car is powered by a 3.6 litre, 6-cylinder petrol engine producing 450 bhp.
