California-based Singer is known for doing impressive restoration work to classic Porsche 911s, but what it’s revealed today essentially takes the company to an all-new level. The 964-gen 911 you see here isn’t a 911 Safari, not by any means. It’s actually what Singer calls “The ACS.” If you’re not familiar with the name, ACS stands for All-Terrain Competition Study, and as you can see, Singer has turned this 911 into an ultimate off-road rally weapon.

Singer ACS – A 964-Gen Porsche 911 With A True Purpose

This Singer ACS is based on a 1990 964-Gen Porsche 911 and was apparently built on request from an “existing, long-term, special” Stringer client that was just itching to have an air-cooled 911 that could “compete in off-road racing and demonstrate all-terrain exploration capabilities.” Here’s the real kicker, though: This client actually purchased two – the white one we’ve showcased here that’s designed for rally and off-road exploration and a red one that’s built for “high-speed, high-grip tarmac events.” I don’t know about you, but to us, it doesn’t seem like either car will be garage queens, and that concept is almost as beautiful as the cars themselves.

With that introduction out of the way, it’s time to talk about power, and the Singer ACS isn’t lacking.But, that’s not the full extent of it, as the owner can extract even more power via computer tuning on demand for different events, should it be needed. A five-speed sequential transmission handles shifting duties and all that raw power is sent to the permanent all-wheel-drive system. Other rally prep includes a longer-range fuel tank, 5-mm thick removable underbody protective panels, and two full size tire-wheel combos. In short, this baby can be repaired easily in the middle of nowhere if needed.

Moving on, the entire body – well, every body panel, that is – is constructed of carbon fiber. All four wheels feature four-piston brake calipers, and the long-travel suspension features two five-way adjustable dampers on each corner (8 shocks in total compared to the 4 on your Porsche 911). Naturally, the interior has a built-in FIA-spec roll cage, FIA-spec bucket seats, and there’s a hydraulic handbrake lever too. A huge screen with navigation means the owner will never get lost.

Of course, this isn’t just an old 911 that’s been cobbled together with random parts in someone’s back yard. Singer does the job right. As an example, the rear bumper on the ACS was milled from a single piece of aluminum. Let’s see you do that in your back yard – I don’t think you will. With all of this said, there’s no word on what a built like this from Singer costs, but it’s apparently “a bit more” than what Singer normally builds. If you have that kind of cheddar to spend, though, the owner has given the okay for Singer to replicate this exact build for any future customer should they want the same exact configuration so something like this isn’t entirely out of reach.
