| The Rainbow Sheikh and the Mercedes Factory Stoppage |
Sheikh Hamad bin Hamdan Al Nahyan commissioned a rainbow fleet of seven S-Class sedans
Sheikh Hamad bin Hamdan Al Nahyan, the Abu Dhabi royal widely known as the Rainbow Sheikh,
is recognized globally for his extraordinary automotive collection. With an estimated net worth of $20 billion, the Sheikh has spent decades curating a vast array of vehicles, currently housed across several museums in the United Arab Emirates. Among the most legendary stories associated with his collection dates back to the early 1990s, involving an order of Mercedes-Benz W126 S-Class sedans that was so extensive it reportedly forced the automaker to temporarily shut down part of a factory.
The commission was a departure from standard luxury car orders. Rather than requesting multiple vehicles with identical specifications, the Sheikh commissioned seven separate S-Class sedans, each finished in a different color of the rainbow. The customization was comprehensive, extending far beyond the exterior paintwork. Every interior detail was color-matched to the exterior, including the carpets, seats, dashboard, steering wheel, and even the air conditioning vents. To complete the collection, he requested an eighth vehicle painted in every color of the rainbow simultaneously. According to reports, the order was so large and time-sensitive that Mercedes-Benz temporarily halted production in part of one of its factories so that workers could focus entirely on completing the bespoke fleet.
Emirates National Auto Museum houses the Sheikh’s custom-built Hummer H1 and monster truck
Today, the entire collection is displayed inside the Emirates National Auto Museum, where visitors can view the rainbow-colored lineup exactly as it was commissioned decades ago. As the son of the late Zayed bin Sultan Al Nahyan, one of the founding fathers and the first president of the United Arab Emirates, Sheikh Hamad’s ability to command such a rapid turnaround from a major manufacturer has become a staple of automotive folklore.

The rainbow Mercedes collection is only a segment of the Sheikh’s massive inventory. His stockpile of vehicles is so large that it fills an entire museum, featuring builds that defy conventional automotive design. Notable items include the world’s biggest Hummer H1, a massive vehicle that features its own set of stairs, a kitchen, and a bathroom. Additionally, the collection includes a Mercedes W128 that has been kitted out with monster truck wheels, alongside several vintage Mini Coopers. The Sheikh’s reputation for commissioning unique, oversized, and highly modified vehicles has made his museum a significant destination for automotive enthusiasts.
TikTok user Sheldon triggered a Mercedes-Benz air quality sensor with vape smoke
| Modern Technology and Sensor Sensitivity |
While the Sheikh’s vintage collection highlights the height of bespoke manufacturing, modern Mercedes-Benz vehicles focus on advanced cabin technology, such as the HEPA (high efficiency particulate air) filter. Designed to remove dust and pollen, the system is particularly useful for occupants with allergies. However, the sensitivity of these modern sensors has recently led to public debate, specifically regarding how they interpret air quality.
A TikTok user named Sheldon, who owns a new Mercedes-Benz, went viral after claiming that his car’s air quality sensor provided definitive proof
that vaping is harmful. In a video, Sheldon demonstrated that after a friend blew vape smoke toward the floorboard, the vehicle’s air quality reading shifted from “normal” to “unhealthy” and then very unhealthy.
The claim sparked significant pushback from other users who pointed out that the filter system is designed to detect any particulate matter, not just substances harmful to human health. One TikToker explained: I don't vape, but like.. it senses anything that's 'NotJustAir,™' and it's meant to do this for the entirety of the car. Like avg pollutant level. You are blowing NotAir™ directly into the sensor.
Others noted that the sensor would likely produce a similarly high reading if a user sprayed air freshener or operated a humidifier in the car, as these devices also increase the concentration of particulates in the air.
The incident illustrates the divide between how vehicle sensors interpret localized pollutant levels and how users perceive those warnings. While the HEPA system effectively clears the air—as Sheldon noted in his video, Now the HEPA filters kicking in and it gets right back down
—the debate highlights that modern automotive sensors are calibrated to detect a wide range of airborne matter, regardless of the source or its specific health implications.
