At Anthony’s Auto Craft, we come across some unique and cool vehicles but every now and then a car comes a long that causes us to pause in awe. Singer, a company specializing in restoration and design modification of existing air-cooled 911s, has done it in spades with its jaw dropping ACS (All-terrain Competition Study).
Inspired by the off-road racing Porsche Rally cars of the 80s and 90s, the ACS is a masterpiece in both form and function. It is quite a departure from the high-horsepower, air-cooled classics on which Singer has built a reputation.
Singer and Richard Tuthill
In partnership with Richard Tuthill of Tuthill Porsche, a team who has dominated Off-Road Events for decades, Singer set out to build the ultimate Rally 911, and we believe they’ve succeeded.
Don’t believe us? Have a look for yourself:
The Singer Tuthill experiment did not disappoint. This Off-Road race ready 911 features all wheel drive, a revised chassis, & racing spec twin turbochargers.
The results of this long awaited experiment have been nothing short of amazing.

Singer Porsche 911 ACS Production
There are currently two ACS builds planned – both for the same client. The second car will be in Corsica Red configured for high speed, high grip tarmac events. As for future iterations and availability to the public, we will have to wait patiently for Singer to make that call.
