Oh My God: The McMurtry Spéirling is The First Car in the World to DRIVE UPSIDE DOWN

Oh My God: They drove the fan car upside down. With a giant fan in the back that generates thousands of pounds of downforce, McMurtry proved that the Spéirling could drive upside down. If a car can produce more downforce than it weighs, it can drive upside down. But no one has ever tried it because with traditional aerodynamic devices (wings, diffusers, etc.) such levels of downforce are only achieved at extremely high speeds. Downforce increases as the square of the speed. So building a tunnel of some kind to get a car up to speed and drive upside down was just a pipe dream. The McMurtry Spéirling Pure, a limited-production, track-only hypercar, generates downforce in a different way. Essentially using a fan to suck air from underneath the car, the Spéirling Pure can produce 4,409 pounds of downforce at 0 MPH; That’s twice the kerb weight. So McMurtry set up a rig at his UK headquarters to flip a Spéirling Pure prototype upside down and actually drive it. Again, McMurtry flipped a car. McMurtry’s rig flipped the car while it was stationary, with the fans on and producing maximum downforce. McMurtry’s co-founder Thomas Yates then rolled the car forward a few feet while it was upside down. The rig then flipped right side up, so Yates could go up a ramp and burn it to the ground for victory. Naturally. It’s one of the most spectacular demonstrations of the effects of aerodynamic downforce we’ve ever seen. Only a fan-car capable of producing that level of downforce could pull off the feat. And it came as McMurtry announced that he had run a sub-minute lap around the Top Gear test track, beating an ex-Renault Formula One car. The Spéirling isn’t the first car to use a fan to create massive aerodynamic downforce. The 1970 Chaparral 2J Can-Am car used a snowplow-powered fan to create downforce, and Gordon Murray's Brabham BT46B did something similar in 1978. Murray revived the fan-car concept for the Gordon Murray Automotive T.50 and T.50S track cars, but only McMurtry offered the public anything that offered such a large fan-generated aerodynamic load.
