When the Porsche 911 Turbo made its public debut at the 1974 Paris Auto Show, it was the fastest production car in Germany. A 3.0 litre turbocharged flat six producing 256 horsepower, a whale tail spoiler, a 155 mph top speed, and a price that embarrassed Ferrari. On paper, it was a triumph.
On a wet road, in the hands of someone who did not know what they were doing, it could kill you.
The car that would become known as the 930 was born partly from motorsport necessity. As Wikipedia notes, FIA homologation rules required Porsche to produce a road legal version of its turbocharged race machinery, and the Stuttgart engineers complied. What they delivered to the public was a machine whose race derived engine had substantially outgrown the chassis designed to contain it.
The problem was physics, and Porsche knew it.
Every 911 carries its engine behind the rear axle. The 930 took this arrangement and added a large turbocharger, shifting even more mass to the tail. The result was a 40/60 front to rear weight distribution, a setup that, as Jalopnik explains, made the rear end fundamentally eager to swing wide, particularly mid corner.
Normally, an experienced driver manages oversteer by keeping their foot on the throttle and applying counter steer. The 930 made this calculation treacherous in a way no previous 911 had, because of what happened when the turbo came on boost.

The single KKK K24 turbocharger sat largely idle below 4,000 rpm and then delivered its full force in one violent surge. A driver who entered a corner at a manageable throttle setting could suddenly find themselves with far more power than they had bargained for, right at the moment their rear tyres were already working at the limit. As Speedhunters describes it, the instinct the completely natural, deeply human instinct was to lift off the throttle. That was the wrong answer. Lifting off transferred weight forward, unloaded the rear, and amplified the oversteer into a spin. The 930 punished the instinct that every other car on the road had taught drivers to trust.
Crashes followed. Fatalities followed. The nickname followed.
SlashGear reports that a 1980 US lawsuit over a fatal 930 accident produced an internal Porsche document containing a quote from the car's own development driver, who described its driving response as "poisonous." The word was used by a man who knew the car better than almost anyone alive.
Porsche was not entirely blind to the problem. The company offered driving lessons to buyers, expanded the rear track, fitted larger brakes, and stiffened the chassis. For the 1978 model year, displacement grew to 3.3 litres with an intercooler added, raising output to 300 horsepower. Wikipedia notes that these changes increased weight, particularly at the rear, which only deepened the handling challenge rather than resolving it. Porsche corporate employees assigned to drive 911 Turbos for business or testing are still required to undergo "Turbo Training" to this day, despite the fact that modern versions bear almost no resemblance to the 930's behaviour.
The nickname itself has older roots. As State of Speed points out, "Widowmaker" was first coined by German Luftwaffe pilots to describe the deeply flawed F104G Starfighter jet, a machine famous for killing the men flying it. When the 930 began accumulating its own toll, the name transferred naturally. In German: Witwenmacher.
The long term consequence of the 930's reputation extended beyond the car itself. According to State of Speed, the difficulty of putting the 930's power down safely pushed Porsche directly toward developing the 959 a car widely considered the grandfather of the modern supercar which used electronically controlled all wheel drive specifically to manage turbo power that rear tyres alone could not safely handle.
The Widowmaker, in other words, made the modern Porsche possible.
Values reflect the legend. Jalopnik records average auction prices for early 930s sitting just above $220,000, with the car's fearsome reputation doing nothing to dampen collector demand. Across the full production run from 1975 to 1989, Porsche built just over 21,500 units in total a low number for a car that looms so large in automotive history.
The 930 was not a bad car. It was an extraordinary car that arrived before drivers, tyres, or safety technology were ready for it. Porsche sold it anyway, offered training that most buyers ignored, and watched it reshape the industry in ways that are still visible on every turbocharged sports car made today.
A lot of great engineering advances have uncomfortable origins. This one had a nickname to match.
