Raised Expectations & The Singer ACS

Think Porsche in motorsport and you will likely think Le Mans.

It’s a natural connection, forged by the manufacturer’s success at the prestigious French endurance race with an unmatched 19 overall victories since 1970. However, if you think 911 in motorsport, you should think rallying.

The announcement of the Singer Vehicle Design All-Terrain Competition Study (ACS) earlier this month has had the majority of the motoring world salivating at the idea of an off-road 911. This is Singer’s first competition study, and was created in conjunction with Tuthill Porsche in the UK, a renowned Porsche rally workshop.


It was a fitting decision by the California-based company, seeing that the very first competition Porsche 911s debuted on the Monte Carlo Rally in 1965, just two years after the car made its first public appearance in Frankfurt in 1963. The car finished fifth overall that year with Herbert Linge and Peter Falk.


In 1967, a factory-backed 911 claimed the European Rally Championship in the hands of Vic Eflord, with Pauli Toivonen (the late Henri’s father) matching that feat the following year. In 1968, Porsche took the first of three successive 1-2 finishes at the Monte, with Elford (’68) and Björn Waldegård (’69 and ’70).

In the years following this dominance, Porsche’s attention increasingly focused on their Le Mans program and their rallying efforts took a back seat.


It was an understandable decision by the Stuttgart company whose, lest we forget, sole purpose is to sell cars.

Rallying during this time was often considered the poor cousin of circuit-based motorsport by corporate types, and with Porsche’s primary export market being North America, a region where rallying was even less popular, you might also understand why they made this decision.


This was in spite of the 911 being quite a good rally car. In 1978, the 911 was once again victor on the Monte Carlo, this time with privateer pairing Jean-Pierre Nicolas and Vincent Laverne at the helm.

In the same year, a factory-entered 911 SC finished just behind Nicolas (driving a Peugeot 504) on the gruelling Safari Rally in Kenya.


By the mid-’80s, Porsche were once again venturing back out onto the rally stages. In co-operation with Prodrive, they established the Rothmans Porsche Rally Team.

Henri Toivonen’s 911 SC/RS finished second overall in the 1984 European Rally championship, with René Metge taking overall victory at the Dakar Rally in a 953.


Following the 953’s success, there was high expectations for the 959 when it debuted in 1985 on the Dakar. Still using the 953’s naturally aspirated flat-six, none of the three cars entered finished. But in 1986, with the cars now turbocharged, they stormed to a 1-2 victory with René Metge and Jacky Ickx.

1986 was also the year that spawned the legend of the third car, which was only entered as a support vehicle but finished sixth overall.


In late ’86, the end of Group B – which the 959 had been specifically developed for – spelled the end of Porsche’s works involvement in rallying.

While there have been privateer entries in the time since, the arrival of the FIA’s R-GT class has seen a popular return of the 911 to world rally stages, and has been the most significant development in recent Porsche rallying history. In 2014, Richard Tuthill (of the above mentioned Tuthill Porsche who co-developed the Singer ACS) gave Porsche its first WRC finish since 1984.

This history should help explain then why the ACS is such an appropriate vehicle for Singer, and why it goes so far beyond being ‘just’ a lifted 911. There’s not just the historical significance behind the car, but there should be a level of expectation, too.

It’s not the first aftermarket 911 of its type; we’ve comprehensively covered some of those other cars before including offerings from E-Motion Engineering and Kelly-Moss Road & Race.

What’s different here is the extremes that Singer and Tuthill have gone to for this special commission.


As is tradition with Singer, the base is a 911 Type 964 – but the similarities with the original car pretty much end there. The bespoke bodywork is custom carbon fibre with clam-shell openings front and rear, and is clearly reminiscent of the 959.

Twin custom long-travel suspension dampers on all four corners with double wishbones, full body strengthening and reinforcement with underbody protection, FIA-specification safety devices and two full spares only scratch the surface of the ACS.

We won’t even go into each and every detail which you have to expect from Singer.


Then there’s the power and drivetrain, a 3.6-litre twin-turbocharged flat-six producing 450hp through a permanent AWD system with plated LSDs and a 5-speed sequential gearbox.


The combination of Singer’s meticulous care for details and Tuthill’s vast experience in creating rally-winning Porsches is almost on odd one. Truth be told, I’m not sure I would take any other company (or companies) seriously if they presented this car to the public.

It should be oxymoronic as it’s a borderline luxury race car, but instead I find myself having complete faith in both Singer and Tuthill that it works. Had anyone else brought this exact car to the world, I think most would have considered it as a bit of a cash-in against Porsche speculators.


While two have been ordered by the original customer who commissioned this car, Singer will kindly sell you one as well. However, while they won’t give a price, it’s expected that you would need to bring a considerable seven-figure sum to the table.

It’s this last part which tends to polarise opinions the most. It’s a huge sum of money, so will we get to see one being used in the wilds of Kenya or tackling the Baja? I certainly hope so, and the images above paint a compelling picture for any potential buyer. You absolutely need to check out Singer’s video, too.

The history of the 911 in rallying sets high expectations not just of the capabilities of this car (which I’m sure is up to the task) but of its potential owners as well. Here’s hoping…

The 997 GT3 was a tough competitor in the Spanish tarmac rally championship until a rule change made them slower than the R5 cars.


I really want to like this. Stylistically it's great but it still leaves me cold. Too clinical, too good. I feel like it's rich men trying to live their childhood fantasies which is always a doomed effort. You simply cannot replicate rallying in the 80's. The romance and the danger of the crude devices pushing boundaries for both man and machine. Engineering for chassis, suspension and engines is so mature now that given enough money it's just a matter of choosing what you want.

"In late ’86, the end of Group B – which the 959 had been specifically developed for – spelled the end of Porsche’s works involvement in rallying."

Not for rally raid though. But i guess it would have been bad press for Porsche to get beaten by a Peugeot 205.


Every race car viewed in its period is clinical, looking back you can get romantic about it, but for its period its was developed to the teams maximum extent. I love Group B and all 80s and 90s racing series, but for those times it was top class engineering and money still ruled.


Of course it was top class engineering and made possible by the ever bigger budgets. The thing is they were charting new territories. Power levels basically doubled in a few short years while the engines became laggy and AWD systems made the cars clumsy. With the power came a whole host of other problems with temperatures and driveability. Cars were catching fire and drivers getting hurt.

Already in early 90's the much heavier and less powerful group A cars were faster than the group B were. That gives an idea on how difficult to drive those cars were. It was the speed of change that created the myth of group B and that cannot be replicated.


"Too clinical, too good". Essentially German then! :)


I cannot get enough of this thing


This Singer ACS has shut down the motoring Internet thus week this far.

Hey Paddy quick one for you. Who is the driver in the video?


That would be Richard Tuthill himself.


>>I think most would have considered it as a bit of a cash-in against Porsche speculators.

That's basically Singer's whole business model.


Whoa. That thing is wild my guy


Is that a bunch of wiring down in the footwell by the pedals? Is there a reason for that? It seems less than ideal


I think it's brake/clutch lines. Probably taken mid adjustment so there would likely be a footplate in place over all of that the rest of the time.


This thing is everything but a rally machine. Rally-raid or Baja, maybe (in an open class) but absolutely not rally. I've seen a lot of people mention the R-GT WRC class, it would never compete in it. First because that class is for 2WD cars, plus it requires a certain number of cars to be made, and to be affordable enough, for people to want to buy it and race it (realisticly affordable and Singer are 2 things that don't belong in the same sentence...). And mostly because to be efficient a rally car must be versatile enough to be competitive on both tarmac and gravel with the minimum of operations and mods. Just look at the FIA homologation details of the new R-GT Alpine A110 that will make its WRC debut next week in the Monte-Carlo Rally, this 911 is clearly not made for rally racing.


The mudflaps look dis-associated because the gap-slashline of the body. Otherwise, its looks all ready for mud fight.


I think the Singer ACS is like the best thing they have ever done
It's just so good!


The Singer ACS made me fall in love with the 911 Safari again
