Porsche has built a lot of 911s over the years—thousands, in fact. But some were never meant for the masses. These are the low-production runs, the special editions, the track-focused builds and experimental prototypes that only a handful of lucky drivers ever got their hands on. Some were built for homologation, others for racing, and a few were just engineering flexes. Either way, these 911s are unicorn-level rare—and if you ever spot one in person, consider yourself part of an extremely exclusive club.

Porsche 993 Turbo S — 345 Built

The 993 Turbo S was Porsche’s swan song for the air-cooled era—and they went out with a bang. Built in 1997, it packed a 424-horsepower twin-turbo flat-six, wider bodywork, and aggressive aerodynamics. Only 345 units were produced, making it one of the rarest factory Turbos. It wasn’t just fast—it was the most powerful air-cooled 911 Porsche ever sold to the public.

Porsche 964 Turbo S Leichtbau — 86 Built

The Turbo S Leichtbau (German for “lightweight”) was a stripped-down, race-ready monster built by Porsche’s Exclusive department in 1993. Only 86 were made, each with reduced soundproofing, thinner glass, no rear seats, and a factory roll cage. It was lighter, meaner, and quicker than the standard Turbo—and it showed just how serious Porsche was about performance-first engineering.

Porsche 964 Turbo S Flatnose — 76 Built

The 964 Turbo S Flatnose is one of the oddballs in the Porsche lineup, and that’s exactly what makes it so fascinating. Only 76 were made, all with the distinctive slant nose borrowed from the 935 race car. Powered by a 385-hp turbocharged flat-six, this special-order machine offered killer performance wrapped in polarizing, track-inspired bodywork.

Porsche 964 RS 3.8 — 55 Built

Built for homologation and tuned for the track, the 964 RS 3.8 is a purist’s dream. With just 55 cars ever built, it featured wider arches, lightweight body panels, a massive rear wing, and a race-spec 3.8-liter flat-six that cranked out 300 hp. It’s raw, fast, and razor-sharp—everything you want in a true RS.

Porsche 930 LE — 50 Built

The 930 LE (Limited Edition) was Porsche’s parting shot for the original 911 Turbo before emissions regs killed it off in the U.S. Only 50 were built in 1989, all with exclusive features like leather-wrapped everything, factory-installed slantnose styling, and a boosted 330-hp version of the 3.3-liter turbo engine. A true collector’s car if there ever was one.

Porsche 911 ST — 24 Built

Before Porsche started naming its performance variants with RS badges, there was the 911 ST. Built in the early ’70s for Group 4 racing, just 24 were produced. These lightweight racers came with bigger engines, flared fenders, and minimal creature comforts. They were purpose-built weapons and helped pave the way for Porsche’s long racing legacy.

Porsche 911R — 23 Built

The original 911R from 1967 is legendary—not for its horsepower, but for what it represented. Just 23 were built as ultra-lightweight, hand-built race cars with fiberglass body panels and Spartan interiors. Weighing around 1,800 lbs, it was Porsche’s first serious attempt at making a 911 into a full-blown track car. Today, it’s the holy grail for Porsche purists.

Porsche 964 Carrera 4 Leichtbau — 22 Built

The Carrera 4 Leichtbau is one of Porsche’s best-kept secrets. Built in 1991 as a lightweight all-wheel-drive prototype, only 22 of these oddball RS-style builds were ever made. It was based on the 964 Carrera 4 but stripped down with thinner panels, Lexan windows, and no rear seats. It was weird, rare, and brutally effective.

Porsche 911 SC/RS — 20 Built

The 911 SC/RS is a little-known factory rally special that saw action in events like the legendary Safari Rally. Built in 1984, just 20 were produced, all with seam-welded chassis, rally suspension, and a 3.0-liter flat-six making 255 hp. It’s one of the most hardcore off-road 911s ever to leave the factory.

Porsche 911 GT1 Strassenversion — 20 Built

The 911 GT1 Strassenversion wasn’t just rare—it was outrageous. Porsche needed to homologate its Le Mans race car for road use, so they built 20 of these monsters with a twin-turbocharged 3.2-liter flat-six cranking out over 530 horsepower. With its mid-engine layout and race-ready DNA, it barely qualified as a street car. But what a car it was.

Porsche 993 Speedster — 2 Built

Yes, just two Porsche 993 Speedsters were ever officially made. One went to Ferry Porsche as a personal gift, and the other was custom-built for actor Jerry Seinfeld. Both were based on the Carrera Cabriolet, modified with a chopped windshield and single-speedster-style rear tonneau. It’s arguably the rarest factory-built 911 variant ever created.
