The turbocharger is, at its core, an elegant piece of engineering. Two interconnected fans: one is spun by the force of an engine’s exhaust flowing over it, a motion that is then transferred to the second fan to make it spin, compressing the air and helping it generate more power. It’s been around for more than a century — found first in planes, ships, and trains, then working its way to trucks and passenger vehicles. These days, they’re ubiquitous in automotive lineups, their ability to provide more power from a smaller package a key tool in gaming government fleet efficiency mandates.

But only one car can claim to be the trendsetter that made “turbo” a household name: the Porsche 911 Turbo.

Ever had a coffee maker, vacuum, or hair dryer with a “turbo” function? You can thank Porsche for that. With the 911 Turbo, the brand took a simple mechanical means of boosting an engine and turned it into a synonym for speed and power, signifying performance in any context. Even Porsche does it now; you won’t find a turbocharger on the all-electric Taycan or  Macan EV, but the automaker still uses the T-word to denote the most powerful variants.

To learn the roots of the term’s current common use, however, we have to trace the lineage of Porsche’s turbocharged sports cars back to the first time Zuffenhausen slapped a snail on a 911’s flat-six. This is the history of the Porsche 911 Turbo.

1975: The 930 marks the start of the 911 Turbo legacy

The very first 911 Turbo wasn’t technically even called the 911 Turbo. Instead, it was known as the 930 Turbo — 930 being the designator used at Porsche to describe the model. (Keep in mind, this was back when the 911’s internal code was still just, well, 911.) The brand had been dallying with turbocharged engines for race cars since the 1960s, but in order to push into the series it wanted, it needed to homologate a vehicle for production that the racers could then be based on. So, come 1975, the automaker slapped a turbocharger on the 3.0-litre flat-six used in the sharp-edged Carrera RS 3.0 and dropped it in a 911 to make the 930.

Okay, it was a little more involved than that; engineers also upgraded the brakes, suspension and gearbox to accommodate the extra power — the latter actually a four-speed manual rather than the five-speed of regular 911s, but the added torque compensated for the difference. From the outside, the most notable change was found at the rear, where a massive spoiler dubbed the “whale tail” for its resemblance to a cetacean fluke increased downforce and helped the engine breathe; wider fenders also added panache.

Generally subtle changes, but the results were anything but. The engine’s 256 horsepower for European versions and 234 ponies for American ones wasn’t groundbreaking by today’s standards, but thanks to a delicate curb weight of around 1270 kilogram and a rear-mounted centre of gravity that aided the rear-wheel-drive car’s acceleration run, that first Turbo — or Turbo Carrera, as it was first known in the U.S. — did the 0-96 kph dash in 4.9 seconds, according to Car and Driver’s testing at the time. It was the first of many eye-popping results the Turbo would rack up in that benchmark trial over the generations.

Just as notable as the acceleration was the manner in which it was delivered. The 930’s big KKK turbocharger was notorious for its turbo lag, kicking on like an afterburner between 3000 and 4000 rpm. If that happened in a turn, the car was given to a sudden bout of oversteer; lifting off the throttle under those circumstances (a natural reaction) could make it worse. Add in the short wheelbase, and the Turbo developed a reputation for spinning out of control, leading it to receive the nickname of “Widowmaker.”

A batch of updates came in 1978, when Porsche pumped the engine up to 3.3 litres and made a few other adjustments to push power in European models to 221 kilowatts and U.S. ones to 196. The brakes, suspension and aerodynamics also received in-kind changes; the revised spoiler was dubbed the “tea tray.” By 1980, shifting emissions regulations made it too hard for Porsche to sell the 930 in the U.S. or Japan; by 1986, though, it was back, with power now up to 210 kilowatts and targa-top and convertible versions entering the fray. A new front end also became available for special order: the so-called Flachbau, or “flatnose,” which swapped out the classic round-eyed 911 face for one inspired by the 935 race car and its ever-so-Eighties pop-up headlights.

1990: After 14 years, the second generation Turbo arrives

After 25 years on sale, the original 911 was finally retired in 1989, replaced by a new generation known internally as 964; to the public, it was still known simply as 911. The future of the 911 Turbo, however, had already been revealed by that point under another name. The Porsche 959, unveiled in 1986, was a bleeding-edge piece of automotive tech that turned the Turbo concept up to 11: it packed a compact 2.8-litre twin-turbo flat-six in the back that made an astounding 331 kilowatts horsepower, but routed it to all four wheels. Comfortable enough to drive daily yet swift enough to claim the title of the world’s fastest production car, it was unlike any street-legal machine the world had ever seen.

So when the new 964-generation 911 Turbo debuted in 1990, it would have been reasonable to expect it to follow closely in the 959’s tire tracks. In fact, though, the super-Porsche was so cutting edge, its influence would be more greatly seen in the following generation of Turbo (more on that in a bit). At launch in 1990, the 964 Turbo stuck with the 3.3-litre engine of the final 930 models — hence the car becoming known as the 911 Turbo 3.3 — albeit tweaked to turn out 316 hp. Likewise, its body more closely resembled the 930 than the 959; it still bore a tea tray spoiler out back, for example.

That first version was just a stopgap, however. By the car’s third model year, in 1993, Porsche had pulled together a more powerful motor to slide into the rear-mounted engine compartment, creating the 911 Turbo 3.6. As the name implies, the new motor — which, in naturally aspirated form, had launched with the 964 generation — displaced 3.6 litres and spun up 264 kilowatts. It wasn’t long for the world, lasting only a year, but it stuck around long enough to earn a star turn in the first Bad Boys film.

Porsche had one last card to play with the turbocharged 964 before it faded away. At the end of production, the company sent 93 chassis to its Exclusiv division to have them built into the 911 Turbo 3.6 S, which packed extra power — more boost and other adjustments turned the wick up to 283 kilowatts  — as well as unique air intakes and spoilers. The Flachbau treatment also returned as an option, although the headlights were now exposed. The Turbo 3.6 S was the first time Turbo and S were paired together, but it wouldn’t be the last.

1995: The third Turbo channels the 959’s legacy

The third-generation 911, known internally as the 993, first hit the streets in 1994 in Carrera form, and it landed with a bang. The tip-to-tail update not only brought a fresh, more streamlined design to the iconic sports car, it also civilised it, revising the suspension to tame some of the car’s more unruly traits, updating the 3.6-litre engine and adding a sixth cog to the manual gearbox.

And, with the arrival of the 993-generation 911 Turbo in 1995, the spirit of the 959 finally made its way to the mainstream sports car. The 3.6-litre flat-six was now twin-turbocharged for improved response, just like the 959; more consequentially, 959-style all-wheel-drive now came standard, helping the Turbo make the most of its 298 kilowatts. As always, flared fenders and a big spoiler in the back visually distinguished it from lesser 911s, but the new rear wing was more organically integrated into the design — less of a whale tail, more of a geologic feature.

The combination of 400 horses and four-wheel grip meant the 993 Turbo could redefine straight-line acceleration for the average driver. In Car and Driver testing, the car blitzed from 0-90 kph in 3.7 seconds — quick today, downright insane almost 30 years ago. As if that weren’t enough, Porsche quickly offered a factory option kit to add even more power, taking the flat-six to 316 kilowatts for the 1996 model year.

Then, as the 993 generation was starting to wind down, Porsche once again decided to spice up the 911 Turbo with a model wearing the S badge. Power was up, of course, to the aforementioned 316 kilowatts — but unlike the old 3.6 Turbo S, the top-shelf 993 Turbo received all the bells and whistles, from extra leather trim to carbon fibre add-ons to unique air intakes for the twin-turbo six. It didn’t make the Turbo much quicker, but it did make it more desirable — even if it meant a 60-percent higher price over the non-S version.
