No car has been built for as long, or reinvented as often, as the Porsche 911. The recipe hasn't changed since 1963 — a flat-six slung behind the rear axle, a shape you know as a silhouette — yet Porsche has rebuilt it eight times, and a whole industry has grown up rebuilding it again. This is the whole car: the eras, the air-cooled faultline, and the restomod scene that values a reimagined one above any new one.
Rear-engined since 1963 — the layout everyone else abandoned, and Porsche alone made work.
Two 911 worlds, split in 1998: air-cooled, then water-cooled — and the older ones became the obsession.
So revered that Singer, Gunther Werks and RUF each built a company on reimagining it.
The gallery above is the whole argument in one place: factory GT3s and Turbos
parked next to Singer’s reimagined air-cooled cars. Same bloodline, two ways of
arriving — Stuttgart builds the new ones, and an entire industry rebuilds the old.
You can’t explain one without the other, which is why this page covers both.
Eight generations, one silhouette
Walk the codes. The original 901/O-series (1963); the long-running
G-series that carried the 930 Turbo from 1975; the 964; then the
993 — the last air-cooled 911, built to 1998. After it, the water-cooled era:
the 996 (the first, 1998), the 997, the 991 (which gave us the
one-millionth 911 in 2017), and today’s 992. Same idea, refined for sixty
years — and still recognisably the car it started as.
The line that splits the faithful: air vs water
The 993’s end in 1998 closed the air-cooled chapter; the 996 opened the
water-cooled one. That switch is the fault line the entire 911 world argues
across. Air-cooled cars are lighter, simpler, louder, and now hold serious value;
water-cooled cars are faster, tougher and far cheaper to run. It is exactly why
the restomod scene fixates on the air-cooled 964 — and why a reimagined one
can cost more than a brand-new 992.
Why the layout works
Hanging the engine behind the rear axle should make a car desperate to swap ends.
Porsche spent six decades engineering around that instead of abandoning it —
mass over the driven wheels for traction off a corner, and a chassis honed to
contain the physics rather than fight it. The pay-off is a car that puts power
down like almost nothing else, and rewards a driver who has learned how.
Owning one in South Africa
Air-cooled 911s have a genuine following here, served by specialists like Cape
Town’s Dutchmann, who work everything from the 1960s cars through to the 993;
Porsche has an official presence for the modern range. The catch is supply and
forex — clean air-cooled 964s and 993s are thin on the ground locally and tend to
command a premium over a straight rand conversion of overseas guide prices. Buy
on condition and history, get any air-cooled engine inspected by someone who
knows them, and check current values before you commit.

The reimagining that changed everything
How Singer turned a 964 into a $1.8M idea
Singer Vehicle Design doesn't build new cars. It takes a customer's own Porsche 964 and rebuilds every component to a standard the factory never attempted — hand-finished bodywork, a rebuilt air-cooled flat-six, and a level of detail that turned 'restomod' into a luxury category.
Its halo, the DLS — Dynamics and Lightweighting Study, engineered with Williams Advanced Engineering — is the high-water mark: a 4.0-litre naturally aspirated air-cooled flat-six spinning to 9,000 rpm for 500 hp, in a carbon-and-titanium car under a tonne. Seventy-five were built, from around $1.8 million each.
That's the number that reframes the whole 911: a thirty-year-old, mass-produced sports car, reimagined, worth more than any factory 911 ever sold. Singer didn't restore the 964 — it proved the platform was never finished.

Straight answers
Why is it called 911 and not 901?
It launched as the 901 at the 1963 Frankfurt show — and roughly 82 pre-production 901s were built — before Peugeot asserted its rights (mainly in France) to three-digit car names with a zero in the middle. Porsche simply swapped the 0 for a 1, helped along by already having the numerals in stock.
What's a "Mezger" engine, and why do buyers pay more for one?
It's named after Hans Mezger — the engineer behind the original 1963 flat-six, the Le Mans-winning 917 flat-12 and the title-winning TAG-Porsche F1 turbo V6. Crucially, the 996/997 GT3, Turbo and GT2 used his race-derived engine, which does NOT have the intermediate-shaft (IMS) bearing that can fail on the ordinary M96/M97 Carrera motors of that era. That immunity is a big part of why a Mezger-engined 911 commands a premium.
Does Singer avoid calling its cars Porsches?
The opposite of what most assume. Singer proudly markets each car as "a Porsche 911 reimagined by Singer." Its settlement with Porsche actually forbids the reverse — it can't brand the cars "Singer 911s" or imply they're a separate marque. Compare RUF, which genuinely is its own registered manufacturer with its own VINs.
How quick was the RUF "Yellowbird", really?
In Road & Track's 1987 top-speed shootout the RUF CTR hit 211 mph — and beat the Porsche 959, Ferrari F40 and Lamborghini Countach gathered for the test. It started as a 911 Carrera 3.2 shell that RUF re-numbered and re-engineered; RUF has been a recognised manufacturer since 1981.
The 964 looks like every old 911 — what made it special?
About 85% of it was new despite the familiar shape, and the 964 Carrera 4 (1989) was the first all-wheel-drive production 911, its system derived from the 959 supercar. It's the generation Singer builds on precisely because it's modern enough underneath to reimagine.
