Supercars are no longer enough. What really removes the hiccups are hyper -sports. Combine the SUPPORTIVE CLASS with technologies and benefits of the Formula 1like him McLaren P1 With Kers and Drs. But if there is a category that is taking off the beast, it is that of the electric with benefits that They seem taken from a video game. Specifically, one English who could have Batman in his garage. It is the McMurtry Spéirling, and its secret is a tuning in a railway tunnel of 1897. Craziness. The McMurtry Spéirling, or Spéirling Electric Hypercar, was revealed in the prestigious Goodwood Speed ​​event of 2022, and there he got some records. Before that, let’s spend the technical record of this car that is not as attractive as a Bugatti Veyronthe aforementioned McLaren P1 or its maximum electric competitor, the RIMAC Neverabut that is a rex tyrannosaurus with lamb skin. Of a lamb 3.5 meters long, 1.7 wide and barely 1.1 high. It has two electric motors that produce a power of 746 kW in the rear wheels, equivalent to about 1,000 hp. The weight is about 1,000 kg, which together with that engine guarantees a huge force. How much? As an acceleration of 0 to 100 km/h in 1.4 seconds or 0 to 230 km/h in less than 5 seconds. Record car. It does not run “much” because it is limited to 305 km/h, so that engine could give much more of itself, and is equipped with a 60 kWh battery that they wait to expand 100 kWh at some point, increasing to 1,200 kg the weight of the vehicle. But with what we have now in hand, we can talk about a car that is leaving the bar high. Very high. At the Goodwood Festival of its debut, the McMurtry Spéirling managed to spray the upload record of its traditional 1.89 -kilometer hill circuit with a time of 39.08 seconds. There have not only been supercoches and hypercoches, but also formula 1 like that of 1998 Nick Heifield. With the McLaren MP4/13, he nailed the clock in 41.6 seconds. In 2019, an electric prototype, the Volkswagen ID.R. He lowered it to 39.9 seconds, and it was the brand that prevailed. Since then, we have seen McMurtry Spéirling making All types of cars bite the dustincluding the imposing Ferrari Laferrari With an atmospheric and 800 hp V12 with Kers of 163 hp or spraying the Mercedes-Am One record in Hockenheim lowering time by 14.1 seconds. The test tunnel. And the secret of this achievement is the wind tunnel. High performance cars are analyzed in wind tunnels in which their aerodynamics are tested. They are cameras in which vehicles are static and it is the air that flows on them, allowing engineers and designers to test aerodynamics. In the case of McMurtry Spéirling, the thing is different because in its wind tunnel, it moves at high speed. The reason? Use a tunnel that could go out in any Batman movie: the Catesby tunnel. It is a railway tunnel of the Victorian era that was built in 1897 and has a line of 2.7 kilometers long and 8.2 meters wide. It is no longer used for its original purpose, and from its conversion It has become an ideal test line for two reasons. The first is because it has constant climatic conditions, which allows engineers to test the car in an environment in which they can develop systematic and precise tests. The McMurtry equipment uses equipment as pressure sensors around the vehicle and high -speed cameras, but it is best to be moving, they can put elements such as wheels, the damping or the great secret of this car under the magnifying glass: the Downforce or ‘soil effect’. Fans, your secret. Because … yes, in a car import all the elements, but when we talk about speed (and that is where the F1 are specimens), it is not so much about the strength of the engine, but how much the car can stick to the ground thanks to the aerodynamics to accelerate better or take a passage through curve faster. And if we see any video of the McMurtry Spéirling, something that attracts attention is that, both in motion and standing before accelerating, it lifts a trail of dust. There is his secret: he has two rear fans that generate a force of up to 2,000 kg. This presses the car against the ground, causing it to leave a Scalextric car and getting a great speed in the curves. It makes a F1 look slow. To get an idea, that aerodynamic load of 2,000 kg that the McMurtry Spéirling has from a stop is the same that achieves a formula 1 when it goes to 250 km/h. And, speaking of formula 1, the video that we leave below is one of those that make a smile of disbelief: In it, we can see spéirling against the Rimac Nevera and a Red Bull RB8. It is very interesting because the Nevera Rimac, which is another electric one that is in the same category, wins in the first test by tip speed because the spéirling limiter comes into play. In the second test, Spéirling has heated the wheels and gets a more tight victory, and in the third we see another surprising thing. It is a braking test in which we see that the Rimac accelerates and runs a lot, but it is difficult for him to stop. Here, spéirling achieves a performance very similar to that of Formula 1, whose braking is spectacular. And it has merit that even with Liam Lawson behind the wheel, that Red Bull looks like a utility next to the other two. Especially next to the great strong point of spéirling: the acceleration from standing. Do you have a million left? Currently, the McMurtry Spéirling is approved for circuit competitions, such as the GT1 Sports Club, but if at any time it is homologated for use in … Read more
