Any discussion about racing (especially Formula 1) will usually include the concept of downforce—the downward lift force that pushes a car toward the ground. Think of it as the reciprocal of the upward lift force (simply called “lift”) that allows fixed-wing aircraft to stay aloft.

But just like how an airplane needs speed to maintain airflow over its wings and keep flying, a car must be driven fast enough for its aerodynamic devices to become effective. Low-speed corners, then, become a problem as forward momentum isn’t enough for things like splitters and diffusers to produce downforce.

However, track-car specialist McMurtry Automotive has a solution to work around that specific problem. Its sole offering, the Spéirling, has a fan system that will supposedly get the car to truly stick to the road regardless of its forward speed. Dubbed Downforce-on-Demand, it can apparently produce 2,000kg of downforce even at a standstill.

With the car tipping the scales at a mere 1,200kg, Downforce-on-Demand should be able to overcome gravity and keep the electric track machine practically glued to the road. But McMurtry isn’t content on mere speculations about its engineering breakthrough, so it has performed an experiment that should keep the skeptics at bay.

With Downforce-on-Demand running, a Spéirling was placed on a special platform. This platform was then rotated until the car was inverted. After that, the test driver inched forward. This reportedly made the Spéirling the first vehicle to be driven upside down, and it demonstrated the effectiveness of its unique fan system. If all this sounds too good to be true, watch this video.

Because Downforce-on-Demand literally keeps the car glued to the ground, the Spéirling can brake later, turn faster, and accelerate earlier at every corner. The need for it to take low-speed sections gingerly is massively reduced. The added benefit of its electric powertrain is that it doesn’t need equipment like a dry-sump lubrication system to reduce oil starvation at high lateral loads.

Those willing to part with £895,000 (P66.9 million) for one of the 100 units to be produced will surely have a lethal track weapon on their hands. It has to be said that anyone pushing the limits in the Spéirling should be concerned about how the human body can withstand the physical punishment of cornering very quickly.
