The Singer ACS Porsche (All-Terrain Competition Study) is a real, functioning off-road marvel.
Oftentimes, we feature great looking renderings, like the BrandBuilds BMW M4 Off-Road concept – but this Singer ACS Porsche is the real deal. What began as a 1990 911 (964) has become an all-wheel drive (AWD), rally-bred beast. The ACS has an air-cooled, 450 horsepower twin-turbo, 3.6-liter flat-six. There is a five-speed sequential gearbox. It has a front, center and rear, mechanical, plated limited-slip differential too.
Twin, five-way adjustable dampers and massive control arms give this Porsche remarkable articulation. Massive brakes sit behind 16-inch aluminum wheels which support big BFGoodrich tires. The roll-cage is FIA-compliant, as are all the interior safety components.
Porsche 911s have a long and remarkable history with rally racing. This particular vehicle is a tribute and reminds many of the 1974 African Safari. That’s where Russling Klaus piloted a 911 S to eighth place overall. There are a variety of other 911s, 959s and other Porsches that the Singer ACS Porsche pays tribute to.
They built this vehicle in collaboration with Richard Tuthill, a legend in classic Porsche rally prep.

Pricing and production (other than the one functioning example) are not available. This one-off rally machine is easily valued well over 1-million dollars. There is a second version of this vehicle on the drawing board. Currently, that model is in the sketch stage, but it looks epic nevertheless.
I know this is an off-road website, but I have to say that I adore the 911. I have always maintained that the Porsche 911 (ALL 911s) are some of the best mass-produced cars ever. Mix that with something that can bound over dunes and take on rally stages – you have the makings on an automotive legend.
