McMurtry has unveiled the production version of its Speirling electric hypercar, which uses giant fans to suck itself to the ground to get unreal performance numbers and has shattered track records.
For the last several years, we’ve seen crazier horsepower and acceleration numbers from electric performance cars, even from previously-unknown brands.
But EVs have gotten so fast that there’s something still holding them back: tires.
Most of the highest-performance EVs on the road are now “traction-limited,” which means they literally could not go any faster if they tried, because tires just can’t keep up.
But there’s a physics trick that can help with that, and it’s one that McMurtry has deployed on its Speirling “fan car,” which has giant fans underneath to push air out the back and to create a low pressure zone underneath the car. This “sucks” the car to the ground, increasing traction without increasing vehicle weight. (Tesla has patented a similar system, possibly for use in the new Roadster).
