Unique Singer Vehicle Design ACS for sale

In 2021, we felt like we’d seen everything there was to see in terms of restomod Porsche 911s. There were million-dollar conversions, track-ready superstars, high-end hot rods, and everything in between. When even Targas got Fuchs wheels and a nice suspension overhaul, there really didn’t seem to be much else to do. But Singer Vehicle Design had other ideas.

The All-Terrain Competition Study was revealed in January 2021, just the kind of big-ticket good news that jolts us out of our collective Christmas slumber. In a collaboration between Singer and Tuthill Porsche – a true dream team of classic Porsche brilliance – two cars were built as part of a single order. The two ACS cars were meant to hark back to the glory days of rally 911s like the SC/RS (before Porsche made a 992 Dakar official) and were built for different terrains. There was a Corsica Red car built with the aim of racing asphalt rallies, and then the Parallax White one revealed to the world three and a half years ago. It was built with dune bashing and desert racing in mind. It’s also for sale now – the actual car.

The specification was as high-quality as we have come to expect from all Singer and Tuthill designs. Nothing was left to chance when it came to creating the ultimate 911 rally homage. Although still based on a 964 (are there any standard ones left today?), the monocoque was reinforced, the spectacular new bodywork was made from carbon fibre and a competition-spec roll cage was fitted. The shock absorbers were five-way adjustable (!), with two units at each corner for ultimate control of the rally car; the gearbox was sequential, there were coated LSDs on both axles and in the centre and the handbrake was hydraulic. In fact, the ACS was more than just a homage to off-road 911s, it was competition-certified – complete with drinks system and GPS navigation.

It’s not clear if this example has been through much since 2021; given the condition it now presents itself in, as well as its likely value, its life has certainly been rather quiet. Not that the driving it has been subjected to has been anything of the sort; alongside the racing gearbox, a Mezger turbo flat-six engine has been upgraded to 450bhp, which with so much carbon in the construction and so little interior space, will make for a very powerful Porsche. Check out these original press photos too – in the right situation, this will be epic fun.

Like the current Dakar, albeit with even more extreme capabilities, there’s scope for all sorts of adventures with the ACS. It would be purely for off-road use, as it was designed and certified for that; whether in actual competition or just for fun, it’s going to be awesome. One would have to hope it could be made road legal too, as it still has lights, wipers, etc. And even if not now, people have made the Zonda Rs road legal. Where there’s a will, there’s a way. Perhaps it could even be made into a tarmac-oriented 911 for race days, like the red car. Tuthill will know all about that, of course. It could be anything, and always be hugely entertaining and unique.

The latter status will of course count for a lot. Before things got really crazy, 450 Classic Study Singers were built – the 964s we all know as Singer restomods. When one of these comes up for sale, it’s usually around a million pounds. The ACS is more extreme, more advanced and a lot rarer; remember, only two were built for one person. We all like to say you won’t see another of this or that specification, but here’s a real one-off from two of the most respected names that make Porsches exceptional. They’ll be air-cooled kings, the talk of the Rennsport Reunion. That alone is worth the millions, before you even think about the fun behind the wheel.
