While this billionaire’s most famous achievement is in defining the computer age, he’s an avid engineer in his own right. And, this passion for engineering stretches far beyond that. Take the case of his monster Porsche 959, which was the nucleus of a 13-year-long legal battle with the US government. Gates bought this twin-turbocharged masterpiece in 1988, which was the most technically evolved production automobile at the time. But because the supercar did not satisfy the American safety and emissions standards, US Customs seized it, and the car sat in a storage for over 13 years before Gates could use it.

Instead of abandoning the car of his dreams, Gates and his father found an automotive expert in Bruce Canepa and a lawyer named Warren Dean who fought for a legal remedy. Their persistence eventually led to the Show or Display law, which permitted rare vehicles that met certain criteria to import into the US with limitations. While the Porsche 959 isn’t the only name in Gates’ car collection, other vehicles such as his first-generation Porsche 930 Turbo, contemporary Ford Focus Coupe, and other electric vehicles demonstrate his love of powerful, innovative cars that progress the motoring experience.

1. Bill Gates Bought a Porsche 959 but Faced a Federal Roadblock

Gates’ 959, however, was not about to impress him right out of the box-until it arrived in the U.S. Shortly after it was delivered, however, some bad news came down for Porsche The German automaker only produced a handful of the sleek, twin-turbocharged supercars less than 350 total, including only 292 of its road cars for customers. As such, the automaker didn’t bother to crash-test and certify the road car to the U.S. Federal Motor Vehicle Safety Standards and EPA emissions regs. Since the costs of certification was not worth the financial gains for such a limited production model, U.S. Customs impounded the GTG’s new Porsche in a Foreign Trade Zone near the port of Seattle the moment it arrived.

The Import Problem That Stopped Gates’ Supercar:

• Purchased his Porsche 959 in 1988
• Fewer than 350 examples produced
• Only 292 customer road cars
• U.S. certification costs proved impractical
• Customs impounded the car immediately

The impoundment, then, was the start of the most extraordinary legal battle in history between the richest man in the world and American car import laws. Instead of letting Gates take his Porsche home, Customs held onto it in storage, where it remained for 4,745 days. The fines against the vehicle grew, but the car survived, and the owner was out thousands of dollars when it was finally released. Gates paid thousands of dollars in storage and fines, alone, finally shelling out approximately $133,000 to keep his dream car at a warehouse while he waited. Other big-name auto-collectors faced similar import hurdles with exotic foreign cars, such as comedian Jerry Seinfeld and fashion icon Ralph Lauren. For Gates, however, the engineering of the Porsche 959 made it more than worth the red tape.

2. The Porsche 959 Was a Technological Marvel Born From Rally Racing

The Porsche 959 traces its ancestry to the German car manufacturer’s victorious Group B rally program which proved itself in a handful of major motorsport competitions. Two years after claiming victory in the Paris-Dakar Rally in 1984, Porsche would record a one-two finish in 1986. The road-going 959 would bring this success to the widest possible market while showcasing the firm’s engineering prowess with groundbreaking electronic features combined with startling performance. Under the hood of the 959 lurked a 2.8-liter flat-six engine with integrated sequential twin turbochargers capable of producing 450 horsepower and 369 lb-ft of torque, allowing this supercar to hit a top speed of just shy of 200 miles per hour and reach 60 miles per hour from standstill in an estimated 3.6 seconds.

Engineering Features That Defined the 959:

• 2.8-liter twin-turbocharged flat-six engine
• 450 horsepower and 369 lb-ft
• Nearly 200 mph maximum speed
• Computer-managed PSK all-wheel-drive system
• Carbon fiber and Kevlar body panels

The 959’s contribution to the Porsche story went beyond performance in a straight line. The PSK all-wheel drive system used computer management of the transfer of power to the wheels, while electronically controlled dampers and adjustable ride height led the path for the car’s technological underpinnings. Active aerodynamics and carbon fiber/ Kevlar body panels served to enhance the car’s progressive attitude. The whole package might seem like the sort of futuristic, forward-thinking engineering concept normally reserved for science fiction from 50 years ago, but for Gates and his computing-oriented career, the 959 wasn’t just an upmarket plaything  it was a magical intersection of machinery and technology that was almost too good to be true.

3. Bill Gates Joined Forces With Bruce Canepa and Warren Dean

Years later, Gates was still not willing to let his Porsche 959 sit languishing in a port warehouse. So he teamed up with automotive entrepreneur and Porsche aficionado Bruce Canepa and Warren Dean, a lawyer from the nation’s capital, to take the fight to the halls of Congress. Their goal was to persuade lawmakers that unique cars like this should be able to enter the country through a special import permit. Since the Porsche 959 never held the proper certifications to be sold traditionally in the United States, Gates’ car wasn’t simply subject to a tariff it needed a special import permit. So, a group of Porsche buffs, led by Gates, successfully pressured Congress for years into passing legislation that made exceptions for these all-but-unique “race cars for the street.”

The People Behind the Legal Fight:

• Bill Gates pursued legal access
• Bruce Canepa brought Porsche expertise
• Warren Dean provided legal assistance
• Congress considered a special exemption
• Years of lobbying advanced reform

At last, the constant efforts bore fruit with the passage of the Show or Display law, a process for importing some unusual vehicles that would not have otherwise been domestically certified. Congress enacted the legislation in 1998, and it was signed by President Bill Clinton on August 13, 1999. This exemption was a boon to a handful of enthusiasts, allowing them to bring in unusual foreign cars that previously would have been inconvenient or impossible to import legally. Instead of junking or permanently storing their vehicles, qualifying owners could petition for approval by demonstrating technological or historical significance. Gates’s decade long battle showed how far the reach of a single person’s effort coupled with automotive expertise, legal counsel, and political connections can extend in solving a pressing issue for passionate, though rare-car, drivers.

4. The Show or Display Law Finally Released Gates’ Porsche 959

The Show or Display exemption offered a narrow legal channel for certain extremely rare foreign supercars to acquire entry into the United States. The new regulation allowed cars built in total quantities of 500 or fewer to qualify if they were deemed to be of extraordinary historical or technological significance. The provision was a lifeline for collectors of ultra-limited production cars that had never been officially approved for regular sales in the United States. Less than a month after the law took effect, the United States Customs office officially released Gates’ 959 Komfort, ending a 14-year odyssey and a decade’s worth of fines for the sale of a single vehicle. Though the wait was finally over, the Porsche still would not be able to be used freely on the road, as it was still subject to restrictions as a Show or Display car.

The Breakthrough That Freed His Porsche:

• Show or Display law established
• Eligible vehicles limited to 500 examples
• Exceptional historical or technological merit required
• Porsche 959 Komfort finally released
• Annual driving capped at 2,500 miles

Once released, the pilot car could be registered for use in the US, again with some restrictions. The single most important of these was the somewhat draconian annual 2500-mile driving restriction, which was instrumental in maintaining the car’s display status. The law also opened the doors to other collectors in search of exotic European models that couldn’t otherwise meet the standards required for certification, though even that didn’t necessarily guarantee freedom from the full panoply of rules that had to be satisfied. Eligible cars had to also meet local EPA emissions standards under the condition outlined in the import regulation, which was the ultimate outcome for Gates.

5. The Landmark Exemption Changed America’s Rare Supercar Landscape

But the passage of the Show or Display exemption had achieved far more than merely getting Bill Gates’ Porsche 959 out of storage. Instead, the rule established a legal process by which individuals could import any vehicle made in fewer than 500 examples, opening the door to imports of automobiles of exceptional historical or technological significance. Car enthusiasts and high-dollar investors in the US could now acquire legendary European machines that hadn’t been successfully certified to existing federal safety regulations, which was especially meaningful for very limited production supercars whose makers would have little motivation to go through the costly certification process. These designated vehicles, naturally, still faced other applicable requirements such as domestic EPA emissions criteria, so the law didn’t entirely eliminate restrictions on importing foreign cars.

How the New Rules Helped Collectors:

• Opened access to rare European models
• Recognized exceptional automotive engineering achievements
• Addressed limited-production certification challenges
• Preserved strict annual mileage restrictions
• Expanded legal import possibilities for collectors

That exemption created new options for collectors interested in driving cars that had previously been off the radar due to strict import regulations. The Show or Display condition (a 2,500-mile annual limit) was still an important factor in the equation, since the car’s history was now linked to the open-or-die status for vehicles allowed in through Show or Display exceptions. Over time, the rules surrounding the Porsche 959 became part of a larger narrative about how American collectors could access key examples of innovative international designs, since Gates’ second battle was still ongoing when the Porsche 959 was eventually declared for legal import into the US. Today, pristine Porsche 959s no longer need a Show or Display exemption to bring them into the US as they are now allowed through the 25-year rule.

6. Bill Gates’ First Porsche Was a 1979 Porsche 930 Turbo

A desire to get the Porsche 959 into America was therefore a natural component of Gates’ obsession with car engineering. In fact, his appreciation for performance cars started quite a long time before his hope of importing the 959. Gates’ first Porsche was a 1979 Porsche 930 Turbo that proved to be his entry into the brand, opening the door to his future love of German cars and their standout design. Instead of simply seeing the car as a way to have something luxurious that was also a luxury item, Gates became interested in cars that had unique engineering success stories, such as when he first bought a Porsche. While he eventually saw the 930 Turbo go out of his collection, it marked the beginning of his love for high-performance automobiles.

The Porsche That Started His Journey:

• First Porsche purchased in 1979
• Classic Porsche 930 Turbo model
• Air-cooled engineering shaped his interest
• Vehicle later sold at auction
• Austrian auction brought $80,000

Perhaps the more dramatic set of details of the sale of the Porsche 930 Turbo, which went at auction in Austria for $80,000, further was a later chapter in the story of Gates’ fascination with cars, since it was one of the many vehicles that he owned that were technically beyond his means, more interesting for their conceptual appeal and construction than their price in terms of what they could accomplish on a road. But that interest in technological innovation, in technologically inspired driving mechanisms, helped explain why the Porsche 959 caught his eye in the first place, even in the face of the substantial legal and monetary roadblocks that were involved in bringing it into the country. The 959 was a particularly forward-looking showcase for the sort of engineering, innovation, and construction techniques that had attracted a younger Gates to the Porsche marque in the first place.

7. A Humble Ford Focus Was Part of Gates’ Daily Driving Life

Gates owned an impressive collection of high performance cars, but he also kept a sensible number of vehicles for everyday driving. In his final years working at Microsoft, for example, he regularly chose to power around in a nondescript 2008 Ford Focus Coupe, a car that offered simple practicality and economic running costs over the more exotic and expensive Porsche 959. Even with his passion for performance cars, he clearly found value in a car that wasn’t designed solely for top speed a car that displayed simple practicality, an understated demeanour and budget-friendly maintenance. The Ford Focus was the perfect vehicle for everyday use, and simultaneously, the Porsche 959 highlighted how a passion for automotive excellence could be combined with sensibility.

Everyday Cars Beyond the Exotic Garage:

• 2008 Ford Focus Coupe
• Regular Microsoft office commuting vehicle
• Practical everyday transportation choice
• Discreet styling and affordable running costs
• Balanced performance with everyday usability

The Focus was not the only everyday car in Gates’ extensive car collection. His garage was also populated with an expensive Mercedes-Benz S-Class, which served as a daily driver and a practical alternative to Gates’ usual mode of travel through the comfort of everyday luxury. He also kept a Chevrolet Volt in his garage, which showcased the different priorities by which he picked his vehicles by virtue of how it was an alternative fuelcar platform in addition to conventional cars. These other cars lived parallel to Gates’ set of exotic sports cars, though they represented the idea of practicality, comfort, and technological interest that could be combined with all the performances one could get out of supercars.

8. Gates Embraced Electric Driving With the Porsche Taycan

Gates has always shown an interest in modern electric vehicles as he’s evolved as a car owner. Given his focus as a charitable person who cares about the environment, this makes perfect sense. His first true electric vehicle was a Porsche Taycan, which he announced during a 2020 interview. This car represented a fusion of his interest in Porsche engines and his preference for electric motoring. This car enabled him to continue to enjoy engineering and cars that he’s been interested in for years without doing away with that interest, and he could also have an electric vehicle that was an extension of the types of cars he’s been a car collector of since the beginning.

The Shift Toward Electric Performance:

• Porsche Taycan purchased by Gates
• Purchase revealed during 2020 interview
• Fully electric driving entered his garage
• Porsche engineering remained a priority
• Electric propulsion reflected technological evolution

As one of the most significant late-career additions to Gates’ garage, the Porsche 911 shows what people who have the means to purchase many different makes and models tend to prefer. By choosing the Porsche, he selected a brand that embodied a certain approach to the experience of driving and a certain focus on engineering, while also choosing something in which performance was achieved in a different way. It was also a brand that reflected his broader interest in environmental giving, and a style of automotive use that is notable among his numerous other travel methods. Earlier vehicles in his garage had shown that he enjoyed mechanical inventiveness, turbocharged power, and the convenience of having transportation for a variety of situations and terrain. The Porsche was also a representation of a rapidly developing automotive tradition that would include electric vehicles, though not erase older sports cars that he enjoyed.

9. Gates Chose a Tesla Model X Despite His Differences With Elon Musk

The new Porsche had a sibling in the form of the Tesla Model X, another electric car that Gates bought to serve his needs as a family vehicle. While it wasn’t as sporty as the Porsche Taycan, it offered a unique seven-seat configuration for carrying off-road gear and the like, providing a complement to the slightly-minivan styling of the first Porsche all-electric vehicles. While there was some overlap in Gates’ two electric cars, this one was a tad more practical given the passenger seating layout, but it still offered all the merits of an electric car in terms of carefree motoring. But that purchase was significant for the fact that Tesla’s main man, Elon Musk, was a known rival of yours truly.

Why the Tesla Model X Stood Out:

• Tesla Model X served family transportation
• Spacious seven-seat layout offered versatility
• Electric power supported everyday driving
• Public disagreements with Elon Musk
• Model featured in Seattle video interview

Though they disagreed in public, it didn’t appear to bother Gates personally when it came to picking an electric vehicle for family use. We saw him drive his Tesla Model X for a while on video in an interview while cruising through Seattle. It was a practical decision, and one that Gates didn’t seem to have much personal investment in, at least in the context of him not being best friends with the Model X chief executive. It was an addition to the broader collection of vehicles his garage would use, allowing him a space to shuttle around with his family while helping him lean into driving electric, much like the Taycan did.

10. Bill Gates Still Preserves His Historic Porsche 959

The car can still be seen in the same garage today (top). The drama of its nearly decade-and-a-half-long storage delay was apparently enough to have preserved it as a treasured part of the collection Gates still drives it on rare occasions and within its 2,500-mile-per-year limit. The rare supercar, which is a collector’s piece for its engineering, low production count, and hard-to-understand import process, is also still tied to the Show or Display loophole that provided the legal avenue by which certain rare cars remained eligible to participate in American car culture without undergoing the normal certification process for factory-made American automobiles.

A Collection Reflecting Automotive Evolution:

• Historic Porsche 959 remains in his garage
• Climate-controlled storage helps preserve condition
• Special occasions bring the car out
• Annual mileage allowance remains applicable
• Modern electric vehicles complement classic Porsches

Gates’s broader automotive evolution demonstrates the spectrum of interests that a diverse personal car collection can encompass. Starting off with the 1979 Porsche 930 Turbo, the line-up progresses through the technically fascinating 959, and on to practical daily drivers such as the Ford Focus Coupe and Mercedes-Benz S-Class. The Chevrolet Volt, Porsche Taycan, and the Tesla Model X bring further variety to the collection, embracing Gates’s interest in alternative-fuel technology and electric motoring. Each vehicle had a role, whether daily driver, family car, semi-professional racer or in transport for a museum collection, and together they document technological change over several generations of vehicles. The Porsche 959 in particular is a significant chapter, for Gates’ persistence to import it helped garner attention for the issues facing collections of scarce foreign supercars.
