For sale is one of a Singer Vehicle Design ACS

By 2021, it was starting to feel like we’d seen everything there was to see when it came to Porsche 911 restorations. There were million-dollar builds, track superstars, high-end sticks, and everything in between. When Targas were also getting Fuchs wheels and nice suspension upgrades, there really didn’t seem to be much to do. But Singer Vehicle Design had other ideas.

The All Terrain Competition study was revealed in January 2021, just the kind of stunning good news to rouse us from our collective celebratory slumber. A collaboration between Singer and Tuthill Porsche – a true dream team of classic Porsche brilliance – a pair of cars were made as part of a single commission. Intended to evoke the glory days of the 911 rally as the SC/RS (before Porsche made the 992 Dakar official), the two ACS cars were built with different terrains in mind. There was a Corsican red car built with the asphalt track as a goal, and then that Parallax White was introduced to the world three and a half years ago. It’s made with dune bashing and desert running in mind. It’s also for sale now – current car.

The specification was as high level as we have come to expect from all Singer and Tuthill builds. Nothing was left to chance when it came to paying homage to the ultimate Rally 911. Although still with a 964 at its base (is there any standard left now?), the monocoque was strengthened, the dramatic new body made from carbon fiber and a competition-spec roll cage was installed. The dampers were five-way adjustable (!), with two units at each corner for ultimate rally car control; the gearbox was sequential, had LSDs worn on both axles and in the center and the handbrake was hydraulic. In fact, more than just a celebration of off-road 911s, the ACS was certified for competition – complete with a drink system and GPS navigation.

It is not clear whether this has endured much hardship and destruction since 2021; Given the condition in which it is now presented, as well as its potential value, the life it has led must have been a quieter one. Not that any of the directions he was subjected to would have been anything like that; As well as the racing transmission, a Mezger turbo flat six was boosted to 450 horsepower, which will make for a very powerful Porsche with so much carbon in the build and so little interior. Check out those original press photos too – in the right situation this will be epic fun.

As with the actual Dakar, albeit with even more extreme possibilities, there is room for all kinds of adventures with the ACS. It would be kept purely for off-road use, as it is designed and certified; whether it’s actually competitive or just for fun, it’s going to be mega. You have to hope it might be road registered too, as it still has the lights, wipers and so on. And even if not now, people have made the Zonda Rs road legal. Where there’s a will there’s a way. Maybe it could even be done on a more track-focused type of 911, like the red car. Tuthill will know all about it, of course. It can be all kinds of things, while always being extremely fun and unique.

That last status will count for a lot, of course. There were 450 Classical Study Singers—the 964s we all think of as Singer restomods—before things got really crazy. When one of these is for sale, it tends to be around the million pound mark. ACS is more extreme, more advanced and much rarer; remember that only two are made for one person. We all like to say you won’t see another of this or that spec, but here is a true one-of-a-kind build from two of the most respected names in making Porsches exceptional. You will be members of the royal family of Luftgekült, the talk of Rennsport Reunion. It’s worth millions on its own, for sure, before you even think about the fun behind the wheel.
