In the event you observe motorsport for lengthy sufficient, you will ultimately hear {that a} System 1 automobile generates sufficient downforce above a sure pace that it may theoretically drive the other way up. McMurtry Automotive turned this idea into actuality after having its Spéirling hypercar full the spectacular feat in a video printed on Friday. Admittedly, the Spéirling’s success might be solely attributed to its proprietary ‘Downforce-on-Demand’ fan system that produces 4,400 kilos of downforce on the push of a button. It is a function that would not be misplaced on the following Batmobile.
McMurtry did not need to cope with the pesky logistics of discovering a tunnel lengthy sufficient to soundly full the run. The British producer constructed a rotating rig at its headquarters in England. The hypercar drove up a ramp onto a steel street deck and got here to a cease. Thomas Yates, the motive force and firm co-founder, then switched on the followers. For these trying to do the mathematics, Spéirling weighs 2,200 kilos. With the stopped automobile’s fan whirling at 23,000 rpm, the rig was rotated to invert the street deck. The rig was locked the other way up. Then, the hypercar rolled ahead a number of toes earlier than stopping whereas inverted. The rig rotated the street deck again down, and the Spéirling drove off like nothing occurred.
‘Downforce-on-Demand’ is not a advertising gimmick
The McMurtry Spéirling, as a 1,000-hp twin-motor electrical hypercar, did not need to clear the opposite hurdles that an F1 automobile would have clear to drive the other way up. Dry-sump combustion engines aren’t designed to run inverted and would ultimately fail catastrophically. Oil would not have the ability to cycle by and preserve the engine lubricated. To oversimplify the system, the lubricant is pumped from an oil tank into the highest of the engine. Gravity pulls the oil right down to a sump on the backside, the place the oil is pumped again into the tank.
This is not the primary time that the Spéirling has achieved the seemingly inconceivable. The prototype hypercar shattered the Goodwood Hillclimb report in 2022 after former F1 driver Max Chilton accomplished the 1.16-mile run in 39.08 seconds. He surpassed the earlier mark by over two seconds. The ‘Downforce-On-Demand’ system is not a gimmick. It permits the Spéirling to have prodigious acceleration and cornering speeds. McMurtry is working in the direction of finalizing a manufacturing model of its hypercar, referred to as the Spéirling PURE. Solely 100 might be produced.
